Surge Tank Hose Replacement Gas

Tools Required

J 38185 Spring 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.

Notice: When adding coolant, it is important that you use GM Goodwrench DEX-COOL™ coolant meeting GM Specification 6277M. If silicated coolant is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner -- at 50 000 km (30,000 miles) or 24 months.

1. Drain the cooling system. Refer to Cooling System Draining and Filling .
