Coolant: Description and Operation






Cooling System/Coolant

Risk of scalding due to hot steam and hot coolant:

The coolant system is under pressure when the engine is warm.

Wear protective goggles and protective clothing to prevent damage to eyes and scalding.

Reduce pressure by covering the coolant expansion tank cap with a cloth and carefully opening.

When doing any repair work, especially in the engine compartment, pay attention to the following due to clearance issues:

Route lines of all types (for example, fuel, hydraulic, Evaporative Emission (EVAP), coolant, refrigerant, brake fluid and vacuum) and electrical wiring so that the original path is followed.

To prevent damage to the lines, make sure there is sufficient clearance to all moving or hot components.

Only use approved clamps for hose connections. Refer to the Parts Catalog.

The arrows on the coolant pipes and ends of the coolant hoses must align when installing.
