NOTE

Disconnecting the negative battery cable on some vehicles may interfere with the functions of the on board computer system. The computer may undergo a relearning process once the negative battery cable is reconnected.

Removal & Installation

NOTE

If your vehicle is equipped with air conditioning, refer to the information regarding the implications of servicing your A/C system. Only an MVAC-trained, EPA-certified, automotive technician should service the A/C system or its components.

In the process of removing the engine, you will come across a number of steps which call for the removal of a separate component or system, such as -disconnect the exhaust system- or -remove the radiator.- In most instances, a detailed removal procedure can be found elsewhere in this manual.

It is virtually impossible to list each individual wire and hose which must be disconnected, simply because so many different model and engine combinations have been manufactured. Careful observation and common sense are the best possible additions to any repair procedure.

Always tag any wire or hose and the components they came from before disconnecting them, so that you can be assured of proper reconnection during installation.
