Cooling System: Service Precautions

Cooling System


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

Risk of scalding due to hot steam and hot coolant.

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


Note the following whenever working inside the engine compartment due to limited space:

• Route all lines and wires in their original locations.

• Ensure sufficient clearance to all moving or hot components.

• When the engine is warm the cooling system is under pressure. If necessary release the pressure before beginning any repair work.

• Secure all hose connections with hose clamps, allocation, refer to the Parts Catalog.

• Use spring type clamp pliers to install spring clamps.

• Always replace gaskets and seals.

• The arrows on coolant pipes and coolant hoses must line up across from each other.
