Coolant 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 open carefully.

Secure all hose connections with hose clamps appropriate for the model.

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