Cooling System Specifications
General Coolant Information
Date Updated -30/01/2002
Many engine failures could be avoided with proper cooling system maintenance. Cooling system maintenance is as important as fuel and lubricating system maintenance. Coolant quality is as important as the quality of fuel and lubricating oil.
The three main functions that coolant serves are:
* Adequate heat transfer and anti-boil protection
* Cavitation erosion and corrosion protection
* Freeze protection
Coolant is normally composed of three elements:
* Water
* Additives
* Glycol
Water
Distilled or deionized water is recommended for use in cooling systems. DO NOT use hard water, tap water, or salt softened tap water in engine cooling systems. If distilled or deionized water is NOT available, use water that meets the minimum acceptable requirements.
NOTICE
Water that does not meet the minimum acceptable limits will reduce engine service life when used in cooling systems.
If you are not sure of the content of the water, contact your Caterpillar dealer, your local water department, your agricultural agent, or an independent laboratory to analyze the water.
Additives
Additives must be included in all coolant mixtures. Additives help prevent the formation of rust, scale, and mineral deposits. Additives protect metals from corrosion, prevent liner cavitation, and contain anti-foaming agents. Additives are depleted during engine operation and need to be replenished. Additives can be replenished through the addition of supplemental coolant additives (used with conventional coolants) or Extender (used with Caterpillar Extended Life Coolant).
Nitrites or nitrite and molybdate additives protect the cylinder liner from cavitation corrosion. Nitrites are depleted, creating the need for additives or Extender. Additives and Extender also contain other inhibitors that can be depleted from cooling systems.
An insufficient additive concentration does not provide adequate protection for cooling systems. An excessive additive concentration can cause additives to drop out of the solution, deposit inside the cooling system, or form a gel in the radiator. Deposits can be in the form of sludge and scale which accumulate on hot engine surfaces. Deposits reduce cooling system effectiveness, or cause water pump leaks.
To maintain conventional cooling system protection, it is necessary to monitor supplemental coolant additive concentration. Maintain the proper additive levels in the cooling system.
Glycol
Engine coolant glycol is normally either ethylene or propylene. Glycol raises the boiling point of water to help prevent boil-over, provides freeze protection, helps prevent water pump cavitation, and reduces cylinder liner pitting.
NOTICE
For ambient temperatures requiring lower freeze protection (higher than 50 percent glycol), use ethylene glycol. DO NOT use propylene glycol.
Proper freeze/boil protection requires the proper ratio of glycol and acceptable water. Use the following charts to determine glycol concentrations to mix with acceptable water.
Use the 1U-7298 Coolant Tester (°C) or the 1U-7297 Coolant Tester (°F) to check the coolant solution periodically to ensure adequate freeze/boil protection. The refractometers give immediate, accurate readings and can be used with ethylene or propylene glycol.
NOTE: For more detailed specifications, refer to: Know Your Cooling System, SEBD0518, and Coolant and Your Engine, SEBD0970, or contact your Caterpillar dealer.
Coolant Recommendations
* Preferred - Caterpillar's Extended Life Coolant (ELC).
* Recommended - Caterpillar's Diesel Engine Antifreeze/Coolant (DEAC).
* Acceptable - Any low silicate coolant that meets Truck Maintenance Council (TMC) Recommended Practice (RP), 329, TMC RP330, or ASTM D4985 requirements when used with supplemental coolant additives.
* Permitted - A mixture of acceptable water and a supplemental coolant additive, where freeze protection is not necessary.
* Unacceptable - Any high silicate coolant that is classified as meeting ASTM D3306.
NOTICE
Most commercial engine coolant/antifreezes are formulated for gasoline engine applications and have high silicate content. High silicates are conducive to cylinder liner cavitation and corrosion. Caterpillar DOES NOT recommend high silicate coolant/antifreezes.
NOTE: Due to individual engine applications, engine cooling system maintenance practices may need periodic evaluation.
NOTICE
Never operate without thermostats in the cooling system. Thermostats maintain the engine coolant at the proper operating temperature. Cooling system problems can arise without thermostats.
NOTICE
Never add coolant to an overheated engine. Allow the engine to cool first. Do not add coolant too quickly. Filling the cooling system at over 19 L (5 U.S. gal) per minute can create air pockets in the cooling system. Engine damage can result.
When filling or adding coolant to the system, premix the coolant solution prior to pouring it into the cooling system. Pure, undiluted glycol will freeze at -23°C (-10°F). Use a coolant solution that is in a range which will provide protection to the lowest expected outside (ambient) temperature and provide the required boil-over protection.
Caterpillar's Extended Life Coolant
Caterpillar's Extended Life Coolant anti-corrosion package is different from the conventional antifreezes that have been used. Extended Life Coolant is an ethylene glycol-based coolant/antifreeze containing organic corrosion inhibitors and anti-foam agents with fewer nitrites than conventional coolants.
Extended Life Coolant was specifically designed for use in diesel engine cooling systems and natural gas engine cooling systems.
Extended Life Coolant extends coolant life to 6000 service hours or four years, whichever comes first. One addition of Caterpillar's Extender is required to maintain Extended Life Coolant.
Major Extended Life Coolant advantages:
* Twice the coolant life
* Considerably less maintenance
* Improved corrosion protection
* Better aluminum protection
* Better liner protection
* Fewer additives (chemicals) and no chemical drop out
* Longer radiator life
* Increased water pump seal life
Extended Life Coolant is available as a 50 percent Extended Life Coolant and 50 percent deionized water solution or in concentrate. See the table for quantities that are available.
NOTE: A 50 percent Extended Life Coolant and 50 percent deionized water solution provides freeze protection to -37°C (-34°F) and anti-boil protection to 108°C (226°F). DO NOT use Extended Life Coolant at reduced concentrations (less than 50 percent), as the additives would be reduced along with the antifreeze. Extended Life Coolant concentrate is available to lower the coolant freeze point when used in arctic conditions. Extended Life Coolant concentration can be increased to 60 percent for -52°C (-62°F) freeze protection.
Extender
Extender should be added to the cooling system at the 3000 service hours or two years, whichever comes first. See the table to determine the recommended amount of Extender to add to Extended Life Coolant.
Extended Life Coolant Cooling System Maintenance
NOTICE
Use only Caterpillar products or commercial products that have passed Caterpillar's EC-1 specification for premixed or concentrated coolants.
Use only Caterpillar Extender with Extended Life Coolant.
Mixing Extended Life Coolant with other products reduces the Extended Life Coolant service life. Failure to follow the recommendations included in this section can reduce cooling system component life.
In order to maintain the correct balance of antifreeze and additives, care should be taken to maintain the proper Extended Life Coolant concentration. Reducing the amount of antifreeze lowers to proportion of additive, thus lowering the coolant's ability to protect the cooling system from pitting, cavitation, erosion, and deposits.
Proper Extended Life Coolant Additions
NOTE: DO NOT add Extended Life Coolant Concentrate as a makeup solution for routine cooling system top-off. Adding concentrated Extended Life Coolant increases the concentration of glycol in the cooling system.
During normal maintenance, use a premixed solution of approved water and Extended Life Coolant as a top-off to the cooling system to bring the coolant to the proper level. Use Extended Life Coolant or a coolant that meets Caterpillar's EC-1 specification. If a coolant that meets EC-1 is not available, use distilled or de-ionized water as a make-up. Check the glycol level of the cooling system with the 1U-7298 Coolant Tester (°C) or the 1U-7297 Coolant Tester (°F). Use Extended Life Coolant Concentrate to restore the proper glycol concentration before the engine is exposed to freezing temperatures.
NOTICE
Do not use conventional coolant to top off a cooling system using Extended Life Coolant.
Do not use supplemental coolant additives other than extender in cooling systems filled with Extended Life Coolant.
If a cooling system using Extended Life Coolant has been to0ped off with a small amount of conventional coolant or if a supplemental coolant additive was added to the system by mistake, the system will not be harmed.
Should the cooling system become contaminated with conventional coolant or supplemental coolant additive exceeding 10 percent of the cooling system's total capacity, perform one of the following actions:
* Drain the cooling system and refill the cooling system with Extended Life Coolant, or
* Maintain the cooling system as if the cooling system is filled with conventional coolant.
Extended Life Coolant Cooling System Cleaning
NOTE: No cleaning agents are to be used when a cooling system using Extended Life Coolant is drained, flushed, and refilled.
Clean water is the only system cleaning/flushing agent required when Extended Life Coolant is drained from the cooling system.
Extended Life Coolant can be recycled. The drained coolant mixture can be "distilled" to separate the ethylene glycol and water for reuse. Contact your Caterpillar dealer for more information.
After draining and refilling the cooling system, operate the engine with the radiator filler cap removed until the coolant reaches normal operating temperature and the coolant level stabilizes. Add coolant mixture as necessary to fill the system to the proper level.
Converting a Cooling System from Conventional Coolant to Extended Life Coolant
NOTE: When the coolant is changed from conventional coolant to Extended Life Coolant, a Caterpillar cleaner should be used. After the use of Caterpillar cooling system cleaners, the system MUST be thoroughly flushed with clean water.
To convert the cooling system from conventional coolant to Extended Life Coolant, perform the following procedure:
1. Drain the coolant.
2. Flush the system with clean water to remove any debris.
3. Use a Caterpillar cleaner to clean the system. Follow the instructions on the label. Caterpillar cleaner is available from your Caterpillar dealer.
4. Drain the cleaner. Flush the cooling system with clean water.
5. Fill the cooling system with clean water. Operate the engine until the cooling system temperature is 49 to 66°C (120 to 150°F).
6. Drain and flush the cooling system with clean water.
7. Repeat Step 5 and Step 6.
8. Fill the cooling system with Extended Life Coolant.
9. Attach a label to the cooling system to indicate the system has been converted to use Extended Life Coolant.
Conventional Antifreeze/Coolant
Recommended - Caterpillar's Diesel Engine Antifreeze/Coolant
NOTE: The following information and recommendations are for Caterpillar's Diesel Engine Antifreeze/Coolant only.
Caterpillar's Diesel Engine Antifreeze/Coolant was specifically designed for diesel engine cooling systems and natural gas engine cooling systems. Diesel Engine Antifreeze/Coolant is an alkaline type, ethylene glycol-based formula containing inorganic corrosion inhibitors and anti-foam agents. Diesel Engine Antifreeze/Coolant was formulated with the correct additive levels to protect metal parts in diesel engines. Diesel Engine Antifreeze/Coolant will furnish adequate corrosion protection, anti-foam protection, and cylinder liner/block pitting protection. Use a 30
percent Diesel Engine Antifreeze/Coolant and 70 percent acceptable water/supplemental coolant additive solution.
Major advantages of Diesel Engine Antifreeze/Coolant:
* Minimal silicate content - High silicate coolants, used with supplemental coolant additives, can cause a build-up of solids over time. Build-up of solids can cause plugging, loss of heat transfer, and water pump seal damage. Diesel Engine Antifreeze/Coolant significantly reduces solid residue build-up that causes inhibitor dropout and water pump seal damage.
* No need to add supplemental coolant additive on initial fill - Supplemental coolant additive must be added with other commercially available coolants.
Diesel Engine Antifreeze/Coolant is available from your Caterpillar dealer in the following quantities:
Proper Antifreeze Concentrations
Use the table to determine concentrations of Diesel Engine Antifreeze/Coolant to mix with acceptable water and supplemental coolant additive.
Acceptable Antifreeze/Coolant
Any low silicate coolant that meets Truck Maintenance Council (TMC) Recommended Practice (RP) 329, TMC RP330, or ASTM D4985 requirements when used with supplemental coolant additives is acceptable.
Caterpillar recommends a minimum of 30 percent glycol to 70 percent water/supplemental coolant additive for proper corrosion protection. All Caterpillar engines with air-to-air aftercooling (ATAAC) require a minimum concentration of 30 percent glycol to prevent water pump cavitation.
While 30 percent glycol is the minimum acceptable volume, Caterpillar prefers a 50 percent glycol and 50 percent water/supplemental coolant additive mixture for optimum performance.
When using Diesel Engine Antifreeze/Coolant, no supplemental coolant additive is necessary on initial fill because supplemental coolant additive is in the Diesel Engine Antifreeze/Coolant. Supplemental coolant additive must be added with commercial coolants meeting ASTM D4985 at initial fill. Supplemental coolant additive must be replenished with both Caterpillar Diesel Engine Antifreeze/Coolant and other commercial coolants at regular service intervals. Refer to the chart for quantities of Caterpillar Liquid SCA to mix with ASTM D4985 commercial coolants at initial fill.
Supplemental Coolant Additive
Supplemental cooling system additive contains alkali. To prevent personal injury, do not drink, avoid contact with the skin and eyes.
NOTICE
The cooling system MUST contain supplemental coolant additive for proper engine protection, regardless of antifreeze concentration.
NOTICE
DO NOT mix Caterpillar's supplemental coolant additive or coolant additive elements with another manufacturer's products. Select a cooling system treatment and use it exclusively.
Supplemental coolant additive is necessary for proper conventional coolant maintenance. Most coolant solutions DO NOT contain sufficient supplemental coolant additive for diesel engine application.
NOTICE
Do not exceed the recommended six percent supplemental coolant additive concentration. Excessive supplemental coolant additive concentration can form deposits on the higher temperature surfaces of the cooling system, reducing the engine's heat transfer characteristics. Reduced heat transfer could cause cracking of the cylinder head and other high temperature components. Excessive supplemental coolant additive concentration could also result in radiator tube blockage, overheating, and/or accelerated water pump seal wear. Never use both liquid supplemental coolant additive and the spin-on element (if equipped) at the same time. The use of those additives together could result in supplemental coolant additive concentration exceeding the recommended six percent maximum.
Use liquid supplemental coolant additive or a supplemental coolant additive element (if equipped) to maintain a three to six percent supplemental coolant additive concentration in the coolant.
NOTE: Caterpillar test kits check for concentration of nitrites in the coolant solution. Some manufacturers' supplemental coolant additive are phosphate based. Caterpillar test kits provide inaccurate results with phosphate based supplemental coolant additive. Commercial supplemental coolant additive products must contain silicates and a minimum of 70 grams per 3.8 L (1 U.S. gal) (1200 ppm) nitrites. If another manufacturer's supplemental coolant additive is used, use that manufacturer's test kit. Follow the manufacturer's recommendations for cooling system treatment and test evaluation.
Test the coolant periodically to monitor supplemental coolant additive levels. Use the 4C-9301 Test Kit to check for Caterpillar supplemental coolant additive concentration. The kit also provides cooling system maintenance recommendations. This kit is specifically for use with Caterpillar supplemental coolant additive's. The 8T-5296 Test Kit can also to check for Caterpillar supplemental coolant additive concentration.
The tables lists the part numbers and quantities of supplemental coolant additive (liquid and solid) available from your Caterpillar dealer. Follow the instructions on the label.
Permitted-Water/Supplemental Coolant Additive
NOTICE
Never use water alone without supplemental coolant additive or inhibited coolant. Water alone is corrosive at engine operating temperatures.
NOTICE
A mixture of water and supplemental coolant additive does not protect against freezing or boiling.
NOTICE
A coolant mixture of water and supplemental coolant additive will cool and provide some protection to engine components, but it will NOT provide normal engine service life.
NOTICE
Caterpillar's recommendation for proper coolant is a minimum concentration of 30 percent glycol and 70 percent acceptable water and supplemental coolant additive (three percent of the total mixture). This recommendation will maintain cooling system corrosion protection.
In applications where freeze protection is not required, or where antifreeze is not available, a coolant mixture of acceptable water and supplemental coolant additive can be used. A water/supplemental coolant additive system should maintain a six to eight percent supplemental coolant additive concentration. DO NOT exceed eight percent maximum supplemental coolant additive concentration. Supplemental coolant additive concentration levels must be monitored.
The 8T-5296 Test Kit can be used to evaluate the supplemental coolant additive concentration in water/supplemental coolant additive coolant, with the following modifications to label instruction Step 3 and Step 5.
STEP 3. - Add tap water to the vial up to the 20 ml mark.
STEP 5. - With the defined procedure, the six to eight percent concentration will yield a 20 to 27 drop range. Fewer drops indicate a low concentration of supplemental coolant additive and more drops indicate a high concentration. Adjust the concentration appropriately.
If the supplemental coolant additive concentration is greater than the maximum of eight percent: drain some of the coolant, refill the system with acceptable water, and retest the concentration level.
Conventional Cooling System Maintenance
Check the antifreeze solution frequently in cold weather to ensure adequate freeze protection. Test the concentration or submit a coolant sample to your Caterpillar dealer in order to monitor the supplemental coolant additive concentration in your engine's coolant mixture every 250 service hours or monthly, whichever comes first. Supplemental coolant additive or a maintenance additive element (if equipped) may be needed every 250 service hours or monthly, whichever come first.
NOTICE
To prevent over-inhibiting the engine's cooling system, do not use both supplemental coolant additive liquid and a supplemental coolant additive element (if equipped) at the same time. Use one method exclusively.
When using Diesel Engine Antifreeze/Coolant and supplemental coolant additive, the cooling system should be drained, cleaned, flushed, and filled with new coolant every 3000 service hours or every two years, whichever come first. Refer to the topic Maintenance Intervals in this manual.
When NOT using Caterpillar Diesel Engine Antifreeze/Coolant and supplemental coolant additive, the drain/flush procedure must be performed at least every year.
After you drain and you refill the cooling system, operate the engine with the radiator filler cap removed until the coolant reaches normal operating temperature and the coolant level stabilizes. Add coolant mixture as necessary to fill the system to the proper level.
Cooling System Cleaning
Draining, cleaning, and flushing the cooling system removes small particles, undesirable chemicals, scale, and other deposit formations. Not performing maintenance on the cooling system can eventually cause engine overheating problems that could result in severe damage to engine and components.
Clean the cooling system if the system becomes contaminated, if the engine overheats, or if foaming is observed.
Caterpillar's Fast Acting Cooling System Cleaner is designed to clean the system of harmful scale and corrosion. The cleaner dissolves mineral scale, corrosion products, light oil contamination, and sludge.
Fast Acting Cooling System Cleaner is available from your Caterpillar dealer in the quantities listed. Follow the product label directions for proper use.
