Fuel system
The fuel system consists of a tank, a fuel pump, an air cleaner, a fuel injection system, and the steel, plastic, and nylon pipes that connect them. The fuel pump is electrically driven and mounted inside the fuel tank.
Exhaust system
All vehicles are equipped with either a single exhaust manifold (four-cylinder engines) or two V6 manifolds, a catalytic converter, tailpipe and muffler. All components are replaceable. The four-cylinder engine uses a "double bottom brick" type converter, which uses both a triple catalyst and a conventional catalyst - oxidizer. The 3.0LV6 engines use a single triple catalyst, secured under the oil pan.
In the 3.8LV6 there are three of them - a pair of small triples under each exhaust manifold and a larger conventional catalyst - oxidizer, located in the exhaust pipe (more detailed information about the catalytic converter is given in chapter 6). Exhaust systems on cars from the point of view of their replacement differ only in manufacturing features and the number of main parts. The systems installed by the manufacturer have one-piece neutralizers. The neutralizer assembly is fastened with bolts. On exhaust systems of four-cylinder engines, a connection with a gap between the catalyst and the muffler is used, the muffler is connected with a U-shaped bolt.
The gap connection is used in the resonator-muffler unit (3.0LV6) or the catalytic converter-muffler (3.8LV6), the muffler is attached with a U-bolt. All exhaust systems usually consist of 4 parts. The rear section of the muffler exhaust pipe (in the middle opening of the muffler) is supplied separately from the muffler.
