Exhaust System Check

WARNING:
To avoid getting burned, do not work on exhaust system when it is hot. Exhaust system must be completely cool before beginning any service on it.

At every interval of periodic maintenance service, and when vehicle is raised for other service, check exhaust system as follows:
^ Check rubber mountings for damage, deterioration, and out of position.





^ Check distortion of exhaust manifold seating surface of cylinder head.
^ Check exhaust system for leakage, loose connection, dent and damage.
^ If bolts or nuts are loosened, tighten them to specified torque.
^ Check nearby body areas damaged, missing, or mispositioned part, open seam, hole connection or any other defect which could permit exhaust fumes to seep into vehicle.
^ Make sure that exhaust system components have enough clearance from underbody to avoid overheating and possible damage to passenger compartment carpet.
^ Any defect should be fixed at once.
