When Should You Upgrade Radiator Fan on Jeep JK?

There can be two possible reasons for upgrading the radiator fan in your Jeep JK.

Either the old one has become inefficient or bad. You may be thinking of replacing the stock cooling fan with a better aftermarket one.

But all of them are almost the same. There is no significant difference between them. Here, let me tell you some signs and symptoms of a bad radiator fan.

Stopped working:

Due to various reasons, the motor gets burned up, or simply the coil fails. As a result, the radiator fan stops working suddenly.

Also, a failed electrical connection can lead to the same situation. Replacing the old radiator fan is the only solution here.

Blown fuse:

A sudden surge in the electrical system can blow the fuse and stop the fan from working. A physical inspection can reveal the problem.

Replacing the fuse can solve this issue, but don’t hesitate to change the whole unit if you notice more problems with the fan.

Engine overheating:

The coolant in your engine keeps the parts from overheating and failing. But do you know which one keeps the coolant at its right temperature?

It is the radiator fan that maintains the temperature. As soon as you see the temperature light turned on in your dash, address the problem right away.

Poor A/C performance:

Similar to the overall temperature control, the radiator fan is also responsible for keeping the A/C unit working properly.

If you don’t feel that inside of the car is not cooling off properly, you will have to check the A/C unit as well as the radiator fan.

Hearing whirring sounds:

As a car owner, you know that any odd noise or sound is alarming. When you hear something suspicious, you have to check the engine immediately.

When the radiator fan is bad or about to go bad, it can create a loud whirring sound or clicking noise.
