Heater Hose: Service and Repair

The heater hoses attach at the engine compartment cowl onto the heater core inlet/outlet and on the left side of the engine.

The heater hoses are serviced separately of each other. The hoses can not be serviced with bulk roll heater hose. If it is necessary to replace a hose, use hose of the exact diameter and size and shape. The hoses are attached using spring tension clamps.
