Regular car servicing can extend the life of a vehicle. The reason for this is simple - defects are found before they become catastrophic.
A small investment in routine car servicing and repair, plus a good inspection programme results in a good return on that investment due to:
e.g. tyres last longer, brake discs do not become scored and in need of replacement.
MOT tests can be carried out on your car up to one month prior to the expiry date of an existing UK MOT certificate provided that a current MOT certificate is presented to the examiner at the time of the test.
On passing the MOT test, the vehicle will receive a certificate valid from the date of expiry of your existing MOT certificate.
All UK cars 3 years old and over require a valid MOT certificate by law. The contents and standards required are set by the Vehicle Inspectorate.
Although there are no moving parts in an exhaust system, it's function and placement on the vehicle means it is one of the hardest worked components on the car. Effects of rust and corrosion by toxic wastes combine to attack the metals of the system leading to noisy and dangerous failures. A 'blown', noisy exhaust is illegal and can lead to a fine. In addition, the leakage of toxic fumes from a failed exhaust into the car can lead to headaches, sickness and drowsiness, with the possibility of catastrophic results.
Exhaust Manifold Connection
The front piece of the exhaust pipe has a special coupling designed to be attached directly to the exhaust manifold which in turn is part of the engine. To absorb the varying stresses of the engine's vibration, the front piece of the exhaust pipe may contain a flexible section to avoid damage to both the exhaust system and the engine.
Modern exhaust systems are designed to remove most of the harmful pollutants from the exhaust gases before release into the atmosphere. This is done by a component fitted into the exhaust system called a Catalytic Converter, or CAT.
A specially lined box filters and converts the hot polluted exhaust gases into a much more environmentally friendly mixture. This mixture then passes along the exhaust pipe to the silencer or silencers before being expelled through the tail pipe and into the atmosphere.
