When adding coolant, it is very important to use GM Goodwrench DEX-COOL®, which is an orange colored, silicate free coolant. If silicated coolant is used on these vehicles, premature engine, heater core and/or radiator corrosion may result. In addition, the engine coolant will require change sooner, at 30,000 milee (50,000km) or 24 months.
If equipped with A/C, have a certified repair shop recover the refrigerant.
Disconnect the negative battery cable.
Disable the Supplemental Inflatable Restraint (SIR) system. For details, please refer to the procedure located in Chassis Electrical of this guide.
Properly drain and recover the coolant in an approved container.
