EXHAUST SYSTEM
INSPECTION
Safety glasses should be worn at all
times when working on or near the exhaust
system. Older exhaust systems will almost always be covered with loose rust
particles which will shower you when dist urbed. These particles are more than a
nuisance and could injure your eye.
CAUTION - Do NOT perform exhaust repairs or inspection with the engine or
exhaust hot. Allow the system to cool completely before attempting any work.
Exhaust systems are noted for sharp edges , flaking metal and rusted bolts.
Gloves and eye protection ar e required. A healthy supply of penetrating oil and
rags is highly recommended.

Fig. 2: Check the muffler fo r rotted spot welds and seams
Your vehicle must be rais ed and supported safely to inspect the exhaust system
properly. By placing 4 safety stands under the vehicle for support shoul\
d
provide enough room for you to slide u nder the vehicle and inspect the system
completely. Start the inspection at t he exhaust manifold where the header pipe
is attached and work your way to the back of the vehicle. On dual exhaust
systems, remember to inspect both sides of the vehicle. Check the complete
exhaust system for open seam s, holes loose connections, or other deterioration
