Some auto parts are installed to perform more than one function. This is true for a vehicle’s body. The body does more than project an image of luxury and style. It also acts as protection and foundation for various auto parts. GMC is aware of this and in turn, produces vehicles with a complete and efficient body having superior exterior features. One component of the body that contributes to its multiple functions is the fender. In GMC vehicles, the GMC fender is a part that not only completes the body’s overall design but also ensures the capability of motorists to improve both the appearance and performance of their cars.

From the outside fenders make a great impact on the look and style of the vehicle. Together with the body, fenders help define the appearance of the car. This is one reason why rear fenders are integrated onto the car’s main body in newer vehicles. Fenders are located at the side portions of a vehicle. They are part of a metal assembly on either side of the vehicle over and around the front and rear wheels. The fender on the front contours from the front doors and runs forward to the bumper and upward to the hood. Meanwhile, a rear fender runs from the rear bumper up to the trunk lid.

Fenders are also intended to house the wheels and tires of a vehicle. They protect other components of the body from rust and sludge formation. Fenders do this by catching the mud and road debris spewed out by a wheel. The fender also contributes in the performance of the vehicle by having extra space in the wheel housing in case motorists may want to get bigger tires and wheels. The GMC fender, for example, gives a spacious housing for GMC parts upgrade, whether for customization or increased performance.

GMC radiators are just some of the essential equipments in vehicles. The radiator is basically responsible for cooling the engine and nearby components by distributing cooling agents like a coolant. This coolant is a liquid, usually a mixture of water with ethylene glycol or antifreeze and a little corrosion inhibitor. This fluid then moves in a closed system from the radiator to the engine, where it conducts heat away from the engine parts and carries the heat primarily to the radiator. GMC radiators are strategically placed behind a vehicle's grille in order to benefit from the cool air coming in. The radiator not only cools the engine but also takes the heat away from the engine.

Radiators are tasked to at least take one-third of the heat produced in the combustion process, in order to avoid overheating. Motorists should know that for each vehicle type and capacity, there is a corresponding radiator. It is important that the radiator suits the needs of the engine for an efficient vehicle performance. For more effective cooling process, some engines have an additional oil cooler. This is a separate small radiator to cool the motor oil. Today, some cars that come with automatic transmissions have extra connections to the radiator, which is responsible to let the transmission fluid transfer its heat to the coolant in the radiator. Meanwhile, Turbo charged or supercharged engines may be equipped with an intercooler. As one of the highly used component in a vehicle, regular maintenance of the radiator is recommended. It is advised that vehicles more than five years old have their radiators check at least once every two years.
