The engine cooling system of your GMC is made up of many complex parts like the radiator, the thermostat, the heater core and the water pump. It's quite amazing, however, that for all of these components to cool the engine efficiently, they would rely on a much simpler component: the cooling fan. Usually made up of simple fan blades and a clutch to control its speed, the GMC fan pulls air to pass through the radiator, cooling the coolant that runs through it and aiding the cooling system to cool the engine properly.

The function of the GMC cooling fan assembly, however, is not as simple as it sounds. The function of pulling air through the radiator core may sound too simple, but to cool the engine efficiently, cooling fan assemblies must do more than that. The air that the fan pulls, for example, must pass directly through the radiator core, not over or around it. The fan must also prevent the hot air that is pushed into the engine compartment from simply re-circulating, thus not cooling the coolant efficiently. Now, a simple fan assembly cannot possibly do this. But GMC fan assemblies can, thanks to the help of another simple component: the GMC fan shroud.

The GMC fan shroud is the hood or ring, usually made of plastic, that encloses the cooling fan. Often mistaken as a simple finger guard that protects your finger from the fan blades, or an unsightly obstruction from easy access to the various cooling fan parts, many people would opt to completely remove the shroud from the fan assembly. Auto performance experts, however, would constantly warn vehicle owners who do so. According to these experts, the fan shroud is not just a simple plastic panel but a very important cooling system part.

The GMC fan shroud has basically two functions to perform: to direct the flow of air through the radiator core and to prevent the re-circulation of the warm air in the engine area. Of course, the fan shroud should be mounted properly for it to perform its function efficiently. It is also important to check on the condition of the fan shroud regularly. If damaged or cracked terribly, it won't be able to perform its job properly and thus would have to be replaced.
