Personal injury can result from hot coolant, steam and alkali. At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns. Remove filler cap slowly to relieve pressure only when engine is stopped and radiator cap is cool enough to touch with your bare hand. Do not attempt to tighten hose connections when the coolant is hot, the hose can come off causing burns. Cooling System Conditioner contains alkali. Avoid contact with skin and eyes.
Note: Put identification marks on all lines, hoses, wires, and tubes for installation purposes. Plug all lines, hoses, and tubes. This helps prevent fluid loss and contamination of the cooling system. 1. Disconnect the battery. Refer to Operation and Maintenance Manual, "Battery or Battery Cable – Inspect/Replace".
