Notice: Failure to flush out the oil cooling system or the engine cooling system
may result in premature failure of the replacement engine.
If the engine is damaged internally and a new engine is installed, make
sure that all foreign material is completely flushed out of the cooling system.
The oil cooler system should also be flushed out (if equipped).
- 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.
