REMOVAL PROCEDURE
1. Remove the surge tank cap.
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.
2. Place a drain pan under the heater hoses near the front of the dash.
3. Remove the dash panel exterior sound barrier.
4. Reposition the heater outlet hose clamp at the heater core using J 38185.
5. Remove the heater outlet hose from the heater core and tilt the hose downward toward the drain pan to drain the coolant from the hose.
