Attention! Allow the exhaust system to cool completely before working on it. When working under the vehicle, securely support it.
Warning! On all models described in this manual, the exhaust system elements are connected by flexible pipes. Such pipes are very sensitive to sharp bends. Do not let the exhaust system hang on such a pipe, otherwise the pipe will be damaged.
1. The exhaust system includes exhaust manifolds, catalytic converter, muffler, exhaust pipe, connecting pipes, brackets, hangers and clamps. The exhaust system is attached to the bottom of the car with brackets and rubber suspensions. If any part of the exhaust system is defective or incorrectly installed, noise and vibrations will occur in the cabin.
2. Periodically inspect the exhaust system throughout its entire length in order to detect malfunctions in time. The exhaust system can have a variety of malfunctions - bent pipes, dents, burnouts, loose connections, corrosion. Leaks in the exhaust system can cause exhaust fumes to enter the passenger compartment. Faulty elements of the exhaust system cannot be repaired - they must be replaced with new ones.
3. If the elements of the exhaust system are rusted to each other, then you will have to use a gas cutter to disassemble the system. Such work in the garage should not be done - you need to send the car to a service station. If you want to save money and replace parts of the exhaust system yourself, in the absence of a gas cutter, cut the pipes with a hacksaw. You can also use an electric or pneumatic metal cutting machine for this chain. Wear protective goggles when doing this work.
4. Below are some tips for repairing your exhaust system.
- A) When removing the exhaust system components, start at the rear of the vehicle and work your way forward.
- b) To make it easier to loosen the fastener, moisten it with a low-viscosity liquid that can penetrate the rusted connection (pic. 16.4, a, b).
- V) When assembling the exhaust system, replace all gaskets, clamps and hangers (pic. 16.4, in).
- G) Lubricate all threaded connections with anti-seize compound when assembling
- d) Make sure that there is sufficient clearance between the exhaust system components and body parts to protect the passenger compartment floor from overheating. Be sure to install heat shields where they are provided by the vehicle design.
