Cooling System Specifications
SMCS - 7606
Coolant Information
The proper coolant mixture is important in today's diesel engines. Diesel engine operating temperatures have increased to improve engine efficiency. This also means proper cooling system maintenance is especially important. Overheating, excessive cooling, component pitting, cavitation erosion, piston seizures and plugged heat exchangers are results of cooling system failures.
Proper coolant is critical, as is the quality of fuel and lubricating oil. Maintenance practices may need to be re-evaluated to properly maintain the engine's cooling system. It is important that this section be read carefully.
NOTICE
Never operate without a thermostat in the cooling system. The thermostats maintain the engine coolant at the proper operating temperature.
Never add coolant or water to an overheated engine, engine damage can result. Allow the engine to cool first. Filling at over 5 U.S. gallon (20 L) per minute can cause air pockets in the cooling system.
Caterpillar does not recommend the use of cooling system solutions that are intended to stop leaks. Use of these products may result in engine damage.
Caterpillar recommends that the coolant mixture contain a minimum of 30% Caterpillar Antifreeze, or equivalent.
The cooling system should be protected with a minimum of 3% concentration of liquid supplemental coolant additive at all times, regardless of the concentration of antifreeze.
If the engine is to be stored in, or shipped to, an area with freezing temperatures, the cooling system must be protected to the lowest expected outside (ambient) temperature.
Check the specific gravity of the antifreeze solution frequently in cold weather to ensure adequate freeze protection.
Coolant Mixture for Caterpillar Engines
Proper engine coolant is a combination of water, antifreeze and supplemental coolant additive. Each ingredient of the mixture must meet specific guidelines for the engine coolant to perform properly. The coolant mixture used in Caterpillar engines must provide the following functions.
* Adequate heat transfer.
* Cavitation erosion protection.
* Freeze & boil protection.
* Sludge & scale protection.
* Corrosion protection.
* Compatibility with system hoses & seals.
Water (Coolant)
All water is corrosive at engine operating temperature. Distilled or deionized water is recommended because of less mineral drop out than hard or tap water. Tap water, even artificially softened with salt, is not recommended for use in your engine's cooling system.
Calcium, magnesium, chlorides and sulfates are all minerals that make up the dissolved solids in the water. Excessive amounts of these minerals (in hard water) can combine with supplemental coolant additives (silicates and phosphates) to form sludge or scale deposits. The mineral deposits (silicates, phosphates, calcium and magnesium) reduce the effectiveness of the cooling system, especially after a number of heating and cooling cycles. They may collect on hot internal engine surfaces and in the cooling system to reduce the effectiveness of the cooling system.
If distilled or de-ionized water is NOT available, use water that meets the minimum acceptable requirements in the chart. To determine your water characteristics, contact the local water department, agricultural agent or an independent laboratory to perform the testing service.
NOTE: Some applications have elected to run with supplemental coolant additive treated water without glycol. Do not mix coolant additive treated water in the cooling system with Caterpillar Antifreeze. This incompatibility could cause cooling system damage because the coolant will have an excessive concentration of coolant additive. Follow the instructions provided by the antifreeze supplier.
NOTICE
Caterpillar recommends that the coolant mixture contain a minimum of 30% Caterpillar Antifreeze (or equivalent) with 70% distilled or deionized water to maintain an adequate cavitation temperature for efficient water pump performance. Antifreeze concentration should be selected to provide protection to the lowest expected outside (ambient) temperature.
Check the specific gravity of the antifreeze solution frequently in cold weather to ensure adequate freeze protection. Premix coolant solution to provide protection to the lowest expected outside (ambient) temperature. Pure undiluted antifreeze will freeze at -10°F (-23°C).
Antifreeze concentrations above 60% antifreeze to 40% water are NOT recommended because the higher concentrations limit the ability of the coolant mixture to absorb supplemental coolant additive.
Use Caterpillar Antifreeze or any low silicate (ethylene or propylene glycol) antifreeze that meets ASTM D4985-89 (GM Specification 6038-M) requirements. Most commercial antifreezes are formulated for gasoline engine applications and have high silicate content. Caterpillar Antifreeze is formulated with a low silicate content and the proper coolant additives for heavy duty diesel engines.
Caterpillar Antifreeze is available through your Caterpillar dealer in quantities that follow.
Adding pure undiluted antifreeze as a makeup solution for cooling system top-off is an unacceptable practice. Add antifreeze premixed Cooling System Specifications with acceptable water to the same freeze protection as your cooling system. Use the Antifreeze Concentration chart to assist in determining the concentration of Caterpillar Antifreeze to use.
Check the coolant solution frequently in cold weather for glycol concentration with the 5P0957 or 5P3514 Coolant Tester (for Caterpillar products) to ensure adequate freeze protection. The testers are identical except temperature scales (°C or °F) and give immediate accurate readings for antifreeze/coolants that contain ethylene or propylene glycol. Both testers are available at your Caterpillar dealer.
NOTICE
If propylene glycol based antifreeze is used, DO NOT allow concentration greater than a 50/50 antifreeze to water mixture. The measurement of freeze protection must be made with a refractive-type tester (5P0957 or 5P3514) rather than the hydrometer-type tester commercially available. The hydrometer-type tester can be used to test ethylene glycol based antifreeze.
Supplemental Coolant Additive (Conditioner or Inhibitor)
The cooling system MUST contain supplemental coolant additives (SCA) (conditioner or inhibitor) to control corrosion, cavitation and deposits. It is also necessary to prevent rust, scale, pitting and/or corrosion of engine parts contacted by coolant. The cooling system should be protected with a minimum of 3% concentration at all times, regardless of the concentration of antifreeze. Use supplemental coolant additive liquid OR an element (if equipped) to maintain a 36% concentration in the cooling system.
NOTICE
Never use antifreeze/water coolant only, in Caterpillar engines without supplemental coolant additive regardless of antifreeze concentration.
Caterpillar or other manufacturer's products can be used as the supplemental coolant additive. Do not mix Caterpillar Supplemental Coolant Additive (Conditioner) liquid or elements with the other commercial products available; select a cooling system treatment and use it exclusively.
Excessive concentration of supplemental coolant additive can form deposits which may cause engine damage, reduce the engine's heat
transfer characteristics and could also accelerate water pump seal wear.
Use the 8T5296 Test Kit to check and monitor the SCA concentration for antifreeze/water coolant mixture. The Caterpillar 8T5296 Test Kit checks for concentration of nitrates in the coolant solution.
NOTE: Some other manufacturers' supplemental coolant additive (SCA) are phosphate based and the 8T5296 Test Kit will not provide accurate results. Caterpillar recommends that their test kit be used to check coolant solution concentration.
If other than Caterpillar products are used as the supplemental coolant additive, follow the manufacturers' recommendation for cooling system treatment and test evaluation. Commercial supplemental coolant additive products must contain silicates and a minimum of 70 gr/U.S. gallon (1200 ppm) nitrites.
Caterpillar liquid supplemental coolant additive (Conditioner) is available through your Caterpillar dealer in quantities that follow.
Supplemental coolant additive must be added Every 250 Hours between initial fill and the Every 3000 Hour cooling system maintenance interval. Install a supplemental coolant additive maintenance element (if equipped) OR .47 liter (1 U.S. pint/16 oz) for each 75 liter (19.5 gal) of cooling system capacity Every 250 Hours.
Pre-charge
Caterpillar Antifreeze DOES NOT require supplemental coolant additive added at initial fill, however additive is required on a maintenance basis. For systems equipped with supplemental coolant additive elements, the last MAINTENANCE element should not be replaced at FLUSH & FILL or Overhaul until the next 250 hour interval.
Water-Only Coolant
Although Caterpillar recommends a minimum concentration of 30% antifreeze, a coolant mixture of acceptable water and Supplemental Coolant Additive (SCA) can be used in applications where conditions do not require freeze protection (or where antifreeze is not available).
A coolant mixture of water and SCA will cool and provide some protection to engine components, however, it will not provide normal engine service life. Antifreeze/water mixtures provide better performance life than water-only coolant.
If the engine cooling system is filled with water ONLY, supplemental coolant additive (Conditioner) concentration should be maintained at 6 to 8 percent maximum. Do not exceed 8% maximum concentration. Check with supplemental coolant additive test kit.
Maintenance of the water-only coolant is the same as maintenance of the antifreeze/water coolant. The 8T5296 Test Kit can be used to evaluate the SCA concentration of water-only coolant with the following modifications to 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 6% to 8% concentration will yield a 20 to 27 drop range. Less drops will indicate under concentration of SCA and more drops will indicate over concentration. Adjust the concentration accordingly to maintain the proper concentration.
NOTE: If the SCA concentration is greater than the maximum of 8%, drain some of the coolant and refill with acceptable water, then retest the concentration level.
Cooling System Cleaning
Clean the system according to the Maintenance Interval schedule or sooner if the coolant is contaminated, if the engine overheats or if foaming is observed in the radiator. Disregard for the proper maintenance of the cooling system can cause engine overheating problems that could result in severe damage to the engine and its components. If testing and proper maintenance of antifreeze and/or SCA concentrations are not performed as recommended in the Maintenance Interval schedule, the system drain interval must be shortened.
Coolant should be drained, the system cleaned and new coolant added by the fuel consumption interval, Every 3000 Hours or Two Years, whichever comes first for the engine being maintained. If not using Caterpillar Antifreeze and supplemental coolant additive as recommended, the drain period must be shortened to Every 1500 Hours or One Year.
When you drain, clean, flush and replace the coolant, small particles, undesirable chemicals, scale and other deposit formations are removed. These deposits reduce the necessary heat transfer characteristics of the cooling system and accelerate wear to the water pump seal. Refer to the Cooling System (Clean/Flush Coolant) topic in the Maintenance Section of this manual.
Caterpillar Cooling System Cleaners are designed to clean the system of harmful scale and corrosion. It dissolves mineral scale, corrosion products, light oil contamination and sludge. Cooling system cleaners are available from your Caterpillar dealer in the quantities listed. Follow the label directions for proper usage.

* Inspect final drives for leaks.
* Be sure covers and guards are firmly in place. Inspect for damage.
* Inspect and repair any transmission leaks.
* Maintain the fuel level to the bottom of the fill neck. Clean the fill cap as necessary.
NOTICE
Overfilling the fuel tank will not allow sufficient air space for normal expansion and can cause loss of fuel out the vent.
* Drain moisture and sediment, as required, from the fuel tank. On earlier models the fuel sump tank drain valve is located under the fuel tank, above the differential.
* Inspect fire extinguisher for proper charge. Recharge if low. Replace if damaged.
* Inspect the steps, walkways, and handholds for their condition and cleanliness. Inspect the Rollover Protective Structure (ROPS) for damage. Contact your Caterpillar dealer for repairs if necessary.
* Make sure the horn, lights, hazard lamps, guards, etc., are in proper working order. Adjust the mirror to allow proper viewing from the seat to see close behind the machine. See the topic Monitoring Systems and Cab Features in the Operation Section of this manual.
* Inspect the operator's compartment for cleanliness. Keep it clean.
* Check that glass hammer is installed on right side window sill.
* Check for oil leaks on suspension pivots, midroller hubs and front idler hubs. Repair if necessary.
* Inspect for rocks or mud build-up between drive wheels (1) and idler wheels (2). Clean if excessive debris is present.
Lines, Tubes and Hoses
Inspect all hydraulic, pressure oil, fuel, high temperature water, etc., lines, tubes and hoses for damage, excessive wear, and looseness. Do not use your bare hands to check for leaks. Use cardboard or a board. See the topic Fluid Penetration in the Safety Section of this manual for more detailed information.
Replace damaged, worn, etc., lines, tubes, and hoses. Contact your Caterpillar dealer for repair or replacement.
Drive Belt Inspection
Inspect for damaged and excessively worn belts. The drive belt is the only moving undercarriage component expected to have substantial wear. However, all components should be examined for damage during each machine inspection.
Use the following guidelines when inspecting these components:
Inside the rubber belt carcass are four layers of cable, similar to the cables used in radial tires.
The most important set of cables are located about 8 mm (.3 in) beneath the inside surface of the belt. This set of cables, called zero degree (0°) cables, controls belt tension.
The other three sets of cables, called breaker cables, are located between the 0° cables and the outside surface of the belt. These are laid in various angles to provide lateral support and to protect the 0° cables.
When any of the cables are exposed to moisture by cuts or gouges in the rubber, they deteriorate by rusting.
To prolong belt life, a kit is available from your Caterpillar dealer to repair the cuts or gouges. Refer to Special Instruction SEHS8713 for more detailed information.
Cuts, gouges and minor wear on the guideblocks are not expected to cause operational problems.
Portions of individual grouser bars that become separated from the belt are not expected to affect traction and need not be replaced.
Pieces of rubber may become separated from the mid roller rim due to rocks and debris that get in the undercarriage system. If more than 50 percent of the rubber is missing from any roller, the roller rim should be replaced.
Pieces of rubber may become separated from the drive wheel rim due to rocks and debris in the undercarriage system. If missing rubber causes slippage between drive wheel (1) and belt (2), the drive wheel must be replaced.
Contact your Caterpillar dealer for information on belt repair or replacement.
Windows, Glass Hammer, and Fire Extinguisher
Use commercially available window cleaning solutions to clean the windows.
Glass Hammer
Inspect
Check if glass hammer is installed and damaged. Replace if damaged or missing. The hammer is located on the right side window sill.
Fire Extinguisher
Inspect
Check if the fire extinguisher is charged and undamaged. Recharge or replace if necessary.
Seat Belt
Inspect for Wear or Damage
Replace the seat belt after three years of usage, regardless of appearance.
Seat belt and mounting hardware must be inspected for wear or damage before operating the machine. Replace the belt or mounting hardware if worn or damaged.
Engine Crankcase
Check Oil Level
NOTICE
Make sure you read and understand the information under the topic Lubricant Specifications in the Maintenance Section of this manual before you proceed with maintenance of the crankcase lube oil system.
NOTICE
The machine must be parked on a level surface to perform this maintenance procedure.
1. Check the oil level with the engine stopped.
