What happens if you remove the fan shroud?
What happens if you remove the fan shroud?
With the cooling fan shroud removed, the engine cooling loses about half its effectiveness. If the cooling fan shroud is cracked, damaged or missing, it can contribute to your engine overheating and less efficient air conditioning system operation.
Do you need a shroud for an electric fan?
An electric fan is preferred because when you need a fan the most (at idle or cruising speeds) an electric fan is delivering maximum air independent of engine RPMs. All shrouded fans should be on the engine side of the radiator. 3. Always use the right shroud with your fan.
What does the fan shroud do?
The fan-shroud assembly is an important component of the cooling system. While the fan is responsible for drawing in air, the fan shroud’s job is to ensure uniform air distribution to the radiator core. By assisting airflow in the engine compartment the fan shroud helps in dismissing excess heat from the engine.
How much does a fan shroud cost?
Radiator fan shrouds cost somewhere between $20-100 on average.
What is a fan shroud on a car?
A fan shroud covers the area around the cooling fan in a car. The shroud is important in the safe operation of your vehicle. Shrouds also reduce fan noise.
Why do you need a fan shroud on a radiator?
Judging from the calculations above, you can see that without a shroud directing the airflow across the entire radiator, you are effectively not using 44% of your radiator. By simply adding the proper size shroud behind your radiator, you’ll ensure that 100% of the radiator’s surface area is used to cool your engine.
Which is the correct position for a fan shroud?
A commonly held thought is that fan blades should recess 50% into the shroud for optimum cooling. To get your fan in the correct position, use fan spacers or shims.
Is the fan shroud in the engine bay useless?
You may think some of the things in your engine bay are pointless, like that fan shroud on the back of your radiator. We are here to tell you: LEAVE it there! You may think that a shroud is a useless piece of plastic or metal, but they really do serve a purpose.
Can a fan be recessed into a radiator?
Electrolysis can result and it can destroy your radiator. A commonly held thought is that fan blades should recess 50% into the shroud for optimum cooling. To get your fan in the correct position, use fan spacers or shims.

How do you install a air conditioner shroud?
When installing, lower the shroud into engine compartment, lower shroud with fan into engine compartment, screw cooling fan onto coolant pump in a counter-clockwise direction (left handed thread). Once hand tight, use a 32mm wrench and coolant pump holding tool and tighten. Install shroud, be sure it is flush with radiator.
How big is the shroud on a cool craft fan?
Fan manufacturers have continued to reduce the thickness of the fans and now there is a shroud from Cool Craft that when combined with the fan only measures 2-5/8-inches thick. It’s made up of a 1/2-inch thick formed-aluminum shroud and one or multiple electric thin-line fans.
Where is the best place to place a fan and shroud?
This makes the traditional mechanical fan/shroud combo impractical. Electric powered fans offer the best alternative. They are thin and can be located anywhere on the face of the core, though near the top is recommended because in top-to-bottom flow radiators hot coolant is returning there from the engine.
