Exhaust System auto parts: Exhaust muffler
Muffler is back part of the exhaust system. It is used to reduce noise level emitted by the car exhaust fumes. A certain noise is made during the exhaust. The noise, made by car, mostly is defined by the muffler. That is why a great importance is attached to this part. If you will substitute the muffler, you can significantly reduce car noise characteristics without any additional efforts.
Outside appearance also plays an important role. Muffler is visible outside. That is why many of car owners highly appreciate stylish chrome-plated mufflers. Car capacity also depends on muffler. Using appropriate model of muffler you can increase your car capacity. And vice-versa, inappropriate muffler or a muffler of a low quality reduce to reduction of car capacity. Corrosion is the main cause of muffler wear. Metal undergoes acids attack that form in the result of car exhaust fumes processing. Sooner or later muffler wears out; this provokes dysfunction and noise level increase. Motor mechanic checks muffler’s state through the agency of tip.
Muffler substitution is a difficult task. It may be difficult to separate details from each other because of rust. When the muffler is substituted all the screws, nuts and gaskets should be substituted too. It is also important the muffler to be placed loosely, without any tension, with enough clearance. Otherwise it may provoke new defects. We have a wide assortment and you can find a lot of spare car parts. If you search any part for your car (flange, window raisers, ignition cable, water pump, brake disk or turn indicator) use “Search” facility. We offer you a qualitative production at low prices.
Main silencer failures
Signs of main silencer failures
Causes of primary silencer failures
The approximate time of main steel (with addition of aluminum) silencer usage doesn't exceed two-three years. After that we don’t recommend to use this part. Obstructions in the punched tubes reduce the capacity of the silencer and don't allow exhaust gases to leak outside. Due to this, pressure in the tubes increases and leads to engine temperature rising.
The exhaust system needs the preventive check every 50000 operational kilometers. Sporting driving style and driving on roads with poor surface are the reasons of more frequent diagnostics.
Main silencer repair and replacement
Minor physical damages or small gashes of the body can be repaired by the ordinary tools for welding. But such measure is temporary as it is required to carry out full replacement of a part in the shortest terms.
It is sufficient to disconnect the silencer clamp and the oxidation catalyst fastener in order to replace broken component. Then it is necessary to remove gaskets, dismantle buffers, oxidation catalysts and the silencer. The procedure won't take a lot of time if you follow sequence of steps and act carefully. To restore the work of exhaust system, it is often sufficient to connect the silencer correctly.
Installation of the silencer demands special attention. This component can damage systems adjoining to it as it is strongly heated when operating. It is important to check seating of the silencer on buffers and the supporting bracket. Also it shouldn't contact other parts of the car which are next to it.
