GMC's Yukon model was introduced in the market in 1992 as a full-size SUV; it was the result of the rebadged full-size edition of GMC Jimmy. The Yukon was offered both in 2-door and 4-door models while rear- and four-wheel drive models were also offered. In 1998, an upscale Yukon was introduced which is the Denali. In Yukon's early models, considering its specifications and body styles, the GMC Yukon is said to have great similarities with Chevrolet's Tahoe. At the introduction of the Denali, it was equipped with a standard 6.0 Liter V8 engine which blasted an impressive 335 horsepower and achieves 13-mpg in the city and 17-mpg on the highway. Also in this model, a 4-speed automatic transmission with overdrive is standard. GMC's Yukon is indeed one great player in the SUV market; with all the great features GMC has provided it and the durable body styles it has. But one thing that's great with GMC's creation is its performance and capability; hence, all GMC models, including the Yukon have reliable radiators.
Your vehicle basically needs a cooling system that includes radiator and water pump; in this system, the water circulates through passages around the cylinders and then it travels through the radiator to cool it off. In some vehicles, the engine is air-cooled instead but this makes the engine lighter but hotter which in turn, decreases the engine's life and performance. So mostly, in this modern automotive era, radiator is popularly used. In this sense, radiators are defined as a heat exchanger that is used to cool an engine once it has reached operating temperature. Usually, radiator and the rest of the cooling system's parts use water mixed with antifreeze or coolant and the cool air that passes through the vehicle's grille cools that water which then returns to the engine through a hose. In some instances, your vehicle have fan that switches on when there's not sufficient air passing through the radiator to cool the water; this is among the most essential feature of the cooling system.
Since radiator is important in your vehicle, especially in its performance, you should at all time make sure that they are functioning and damage-free. You should replace damaged radiators so you can always get high-performance function from your GMC Yukon. The market offers lots of replacement products for your GMC Yukon radiator; available choices are OEM radiator, aftermarket radiator, factory original radiator or even used GMC Yukon radiator that are available in most parts dealers in the automotive market.
