CAUTION!!! Never work on a hot vehicle. Serious
injury in the form of burns can result if the vehicle has
been in use. Allow vehicle to cool prior to installation.
Always wear eye protection when working on or
under any vehicle.
Note:
With a used vehicle, we suggest using a penetrating spray lubricant to be applied
liberally to all exhaust fasteners. When doing so allow a signicant amount of time for the
chemical to lubricate the threads before attempting to disassemble. On your application
these are the bolts in step 8, located on the rear passenger side of the engine.
