Heater Inlet Hose Replacement (RPOs L61, LE5)

Tools Required

J38185 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.

1. Remove the surge tank cap.
2. Slide a drain pan under the front of the dash under the heater inlet hose.
3. Remove the dash panel exterior sound barrier.
