Heater Hose: Service and Repair
Heater Hose Replacement - Inlet
HEATER HOSE REPLACEMENT - INLET
TOOLS REQUIRED
J 38185 Hose Clamp Pliers
CAUTION: With a pressurized cooling system, the coolant temperature in the radiator can be considerably higher than the boiling point of
the solution at atmospheric pressure. Removal of the surge tank cap, while the cooling system is hot and under high pressure, causes the
solution to boil instantaneously with explosive force. This will cause the solution to spew out over the engine, the fenders, and the person
removing the cap. Serious bodily injury may result.
REMOVAL PROCEDURE
1. Remove the surge tank cap.
2. Slide a drain pan under the front of the dashboard under the heater inlet hose.
3. Reposition the heater inlet hose clamp at the heater core using J 38185.
4. Remove the heater inlet hose from the heater core and tilt the hose downward toward the drain pan to drain the coolant from the hose.
