Removal Procedure
Notice: When adding coolant, use DEX-COOL® coolant. 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 mi) or 24 months.
- Disconnect the negative battery cable. Refer to
Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing
any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to
the vehicle or its components.
