High quality fan shroud keeps your car engine cool and protected from unwanted damage. Check out Car Parts' wide range of automotive products and resources for you, including fan shrouds.
The radiator shouldn't be solely credited for your vehicle's reliable engine cooling system. There are other auto parts that play a crucial role in keeping engine temperature at a manageable level.Among these is the fan shroud. The fan shroud is an important component of the cooling fan. While the cooling fan's blades are responsible for drawing in low-temperature air, the fan shroud's job is to make sure this air gets to the radiator core.By assisting airflow in the engine compartment, the fan shroud helps in removing excess heat from the engine. The fan shroud also prevents the recirculation of heated air through the cooling fan.So for the cooling system to work properly, the fan shroud should always be in good shape. If you need a replacement unit, you're now at the perfect place to get your vehicle's next fan shroud.

It is normal for your car’s engine to generate heat due to combustion. This is taken care of by the cooling system. Thermal management is crucial in keeping your engine running for longer periods of time. Now, you might think that the cooling system is as simple as the radiator blowing cool air into your engine but we’re here to tell you there’s a lengthy process before the cooling takes a full cycle.
Automotive thermal management is a complex process that involves multiple components like an electric cooling fan, a radiator, a water pump, and a thermostatic switch (on modern vehicles). The radiator is what cools the heated coolant after passing through the engine, and the fan directs outside air toward the radiator. If you look at your cooling fan, you’ll notice a metal or plastic case that encloses the fan from the side. This metal or plastic case is actually a radiator fan shroud.
Get to know your car’s cooling system
Before we go straight to fan shrouds, let’s understand how a car’s cooling system works. Your car’s cooling system uses a coolant or antifreeze, which is a fluid that’s used to remove the heat from your engine. When this coolant passes your engine, it draws out and absorbs the thermal energy. This makes the coolant so hot that you’re not allowed to touch the radiator cap when your engine is running. The heated coolant then gets transferred to the radiator through the upper radiator hose. The coolant is cooled in two ways: through ram air or air from the cooling fan.
If your car is moving fast enough, your radiator relies on ram air, which is an airflow that’s forced through the radiator via the grille and air dam. Cooling fans, on the other hand, enhance airflow during idling or at low speed drives. Airflow from the cooling fan can be further enhanced using a fan shroud.
What is a fan shroud?
Fan shrouds are the plastic or metal protectors that cover your fan blades. One obvious function of the fan shroud is to protect and cover the fan blades from getting hit by debris. It also protects someone who might accidentally touch the blades from severe injuries. However, fan shrouds are not just finger guards or safety coverings. They also channel concentrated air to your radiator and ensure optimum engine cooling. These are done by restricting air from being dispersed to different directions other than the radiator, resulting in a uniform air distribution to the radiator core.
Further, fan noise is reduced through the help of the fan shroud mainly because it reduces air turbulence. The result is a smoother airflow throughout your car’s cooling system.
Types of cooling fan
In order to deeply understand cooling fan shrouds, you must know the different types of cooling fans. This is essential as some fan shrouds are designed to exclusively fit only one type. Here are the two different cooling fan types in the market.
Belt-driven cooling fan
Belt-driven or mechanical cooling fans are mounted behind the radiator for one reason: they are connected to the engine’s crankshaft. They pull the hot air from the radiator and release it to the atmosphere. Belt-driven fans are believed to be less efficient because they increase engine drag.
Electric cooling fan
Electric cooling fans are more efficient than mechanical fans because they are powered by another power source instead of the engine, which maximizes engine power. A pusher electric cooling fan can be installed as an auxiliary fan to support the belt-driven or electric puller fan behind the radiator.
CarParts.com’s catalog includes fan shrouds that fit both a radiator fan and an auxiliary fan. There are aluminum fan shrouds as well as universal fan shrouds to suit your cooling system repair needs.
Cooling fan location
There are two different locations of cooling fans and it depends on which type of fan is installed on your radiator. Some cars have the cooling fan installed in front of the radiator, while others have it behind. Below are the types of electric cooling fan.
A cooling fan mounted in front of the radiator is a pusher fan. Pusher fans are designed to force or blow air through the coils of the radiator.
If an electric cooling fan is mounted behind the radiator, it is a puller fan. This type of cooling fan pulls the hot air from the radiator core, dispersing it rearwards.
Other fans are designed to be both a puller and pusher, meaning you can either mount them in front or behind your radiator. These fans feature detachable blades that you can flip to face the opposite direction. Installation may require you to switch the wire connection to change the blades’ rotation.
What happens if you remove the shroud?
It might appear like removing the fan shroud won’t make a difference in how your cooling system works, but in fact, it makes a huge difference. Unshrouded fans only move air through a portion of the radiator equal to the fan’s surface area. Even the best electric radiator fans wouldn’t be efficient enough without a fan shroud. That’s because shrouds create a vacuum that sucks air across the radiator assembly.
It is believed that removing a fan shroud could reduce cooling by a whopping 50%. You can assure that the entire surface area of your radiator is air cooled by installing the proper fan shroud size. If your cooling system fails to perform its task properly, the heat from your engine may build up and result in engine problems.
When to replace a fan shroud
One way of finding out a damaged fan shroud is through visual inspection. You should be able to locate the cooling fan either in front of or behind your radiator assembly. The shroud is exposed in plain sight and any damage should be easily seen. Another way of knowing when to replace the shroud is by observing noises under the hood. Damaged fan shrouds usually cause clicking and flapping sounds when the fan is on.
Should you find a worn fan shroud, immediately get a replacement and have it fixed. Driving without a fan shroud is driving with 50% less cooling capacity and might result in engine problems when prolonged.

Supply Your Engine the Right Air Amount Using a Fan Shroud
A car engine produces heat that reaches 280F in only a few minutes. This is why a cooling system is included to maintain the engine's temperature at a tolerable level. The radiator, fan, and fan shroud are parts of that system, and the focus of this segment is on the fan shroud. It may look like a part your car can live without, but it actually provides an irreplaceable function. Read on to find why, and discover more information.
What's a fan shroud and how does it work?
Basically, a fan shroud surrounds the fan, that's it; but there's an even deeper explanation. Since the fan assists the radiator in cooling the engine, the radiator needs all the air it can get. The fan shroud is designed to gather the moving air from the fan to the radiator. If there's no fan shroud, the air from the fan will scatter, and the radiator will not cool the engine effectively.
Are fan shrouds the same for all types of cars?
Fan shrouds are mostly different for every car type. Although the difference can be minimal, you should remember that it has to equate the size of the fan, and the need of the engine. The material used also varies; it can be plastic, aluminum or steel. Another factor you should consider is the single or dual fan types. To make it easier, check your current fan shroud and see whether it has only one fan or two.
How difficult is it to put a new fan shroud?
If you have a wrench at home and some safety gear, then there's no difficulty at all. Fan shrouds have been designed with bolt-on installation. Keep in mind the size of the fan shroud though, it ranges from 16-20 inches; make sure to get the size you need.
An Easy Reference for Fan Shroud Replacement
The arrangement of the cooling system in your engine begins with the radiator; next is the fan and then the fan shroud. Since this guide is for the fan shroud replacement, you will first discover how to remove the radiator and then the easier portion which is the fan shroud. This step-by-step guide will show you how.
Difficulty Level: Hard
Tools you'll need:
- Floor Jack
- Jack Stands
- Oil Pan
- Socket wrench
- Socket Set
- Screwdriver set
- New fan shroud
Safety Advice: Before you begin, wear a safety eyewear first. Use gloves to avoid grease all over your hands and wear appropriate working clothes.
Step 1: Lift the front portion of the car using the floor jack.
Step 2: Secure the desired height by placing the jack stands underneath the car's solid frames.
Step 3: Place the oil pan underneath the radiator drain hose, and pull the hose off. Make sure it the pan catches all the coolant.
Step 4: Remove the radiator hose located on top using the screwdriver or the socket wrench.
Step 5: Disconnect the electric connection of the radiator fan, and remove the bolts that hold the fan. If the fan is connected to the radiator, you have to pull-out the radiator first.
Step 6: Remove the bolts that hold the radiator on the top and lower portions, and pull the radiator out. You will also be able to pull-out the fan as well.
Step 7: Locate the bolts on top that hold the fan shroud on top and use the socket wrench to remove it. Likewise, find the retaining clips at the bottom, snap it loose, and remove the fan shroud.
Step 8: Attach the new fan shroud.
Step 9: Return all the parts by doing the entire procedure starting from the previous step. Remember to refill the car's coolant before you switch the engine on.
The fan shroud replacement itself takes only 10-15 minutes, but since you have to deal with the radiator and the fan, the entire process is around 1-2 hours to complete.
