What is a radiator fan shroud and where is it located?
The fan shroud helps the radiator fan cool the radiator more effectively. Basically, coolant from the radiator is pumped through the engine via the water pump, and the warm coolant then exits back into the radiator. The warm coolant is then cooled down by the air that is passed through the radiator by the radiator fan. Cooled coolant is then pumped back into the engine, and the process repeats itself.
The radiator fan shroud is a plastic piece that surrounds the radiator fan. It is partly funnel shaped. This helps it draw cool air through the radiator. It also keeps warm air from recirculating through the radiator. This helps the fan cool the radiator more effectively, which in turn keeps the engine cool and prevents overheating.
The radiator fan shroud mounts to the radiator and is secured to it by bolts. Fan shroud designs vary from one model to another. Some are one piece, while others are made of an upper and a lower piece. In many cases, the fan shroud is also what holds the radiator fan in place. For most modern cars, the fan and shroud are integrated together into one assembly (rather than being two separate parts) and are not sold separately. Trucks and large SUVs are a different story, however.
How do I know if my radiator fan shroud needs to be replaced?
Since it is exposed to extreme heat on a regular basis, radiator cooling fan shrouds can break down or overheat and melt. In some cases, they can also be damaged by the cooling fan itself. If a bearing wears out in the fan motor, it can cause the fan blade to shift and strike the shroud, causing damage to the shroud (as well as the fan blade itself).
A damaged fan shroud will hamper the efficient flow of cool air through the radiator. This can result in overheating the engine. Since driving at speed pushes some air through the radiator, a damaged fan shroud is most likely to cause overheating at low speeds or especially when the vehicle is not moving. If your vehicle’s engine is overheating at low speeds, it's time to get a replacement radiator fan shroud. Also, if the shroud is damaged, the radiator could also get damaged by the fan being lose and moving out of position. In this case, a small problem that could be solved with a simple fix could become more costly if left unfixed.
Can I replace a radiator fan shroud myself?
With a bit of effort, removing a radiator fan shroud can be accomplished by a do-it-yourselfer. The difficulty and exact method of doing so will vary depending on your fan’s design. First off, as with any electrical job, it is recommended to disconnect the battery prior to further work if it’s an electric fan. Next, you may have to disconnect the radiator hoses in order to pull the fan shroud up and out of the engine compartment. Usually, this is not necessary but taking a look at your setup ahead of time is always a good idea just to be sure.
Since the shroud is around the fan and wedged between the engine and the radiator, you will often have to remove the fan blade or the radiator itself to make room to pull out the fan shroud after you have unbolted it from the radiator. You can remove the top fan shroud of a two piece assembly without removing the fan, but may still need to remove the fan to take out the bottom piece. Assemblies that include the fan and shroud can be pulled out as one piece once the fan wiring has been disconnected. After you install the new fan shroud (by reversing the removal procedures) and replace all the parts removed, you should run the engine to check that the fan and shroud are aligned correctly and that the fan is not striking the shroud at any point.
