Only inspect or repair the exhaust system when the system is completely cold. When working under the vehicle, make sure it is securely mounted.
Muffler and pipes
The exhaust system consists of the exhaust manifold, mufflers and all connecting pipes, brackets, hangers and clamps. The exhaust system is fixed to the body using brackets and rubber hangers.
If any parts are not secured correctly, excessive noise and vibration may be transmitted to the body.
Inspect the exhaust system regularly. Look for damaged or bent parts, open seams, holes, loose connections, severe corrosion, or other defects that allow exhaust gases to enter the vehicle. In general, exhaust system components that are worn out cannot be satisfactorily repaired; they should be replaced.
If the exhaust system components are connected together due to severe corrosion or rust, it may be necessary to cut off the old components with a hacksaw. Remember to use reliable glasses to protect your eyes from metal filings, and gloves to protect your hands.
Below are some recommendations for repairing the exhaust system:
- When removing exhaust system components, start at the rear of the vehicle and work your way forward.
- To make it easier to loosen the exhaust system nuts and bolts, use a rust remover.
- When installing exhaust system components, use new gaskets, hangers and clamps.
- When assembling, apply anti-corrosion compound to the threads of all exhaust system nuts and bolts.
- Make sure there is extra clearance between newly installed parts and all points on the underbody to avoid overheating the floor and possible damage to the carpets and insulation. Pay special attention to the catalytic converter and the protective screen. Also make sure the exhaust pipe does not come into contact with suspension parts, etc.
