General Description
Maintenance
WARNING:
To avoid the danger of being burned, do not touch the
exhaust system when the system is hot. Any service on
the exhaust system should be performed when the sys-
tem is cool.
At every interval of periodic maintenance service, and when vehi-
cle is raised for other service, check exhaust system as follows:
• Check rubber mountings (1) for damage, deterioration, and
out of position.
• Check exhaust system for leakage, loose connection, dent
and damage.
• If bolts or nuts are loosened, tighten them to specified torque
referring to "Exhaust System Components" in this section.
• Check nearby body areas damaged, missing, or misposi-
tioned 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.
