What should I do if my radiator fan is not working?

A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan. The fan itself often uses a big fuse of around 50A, while there might also be a separate small fuse to the fan control module.

How to troubleshoot an electric cooling fan problem?

1.Has the Cooling Fan Actually Failed? 1 If the fan comes on when the AC is running at MAX, but doesn’t run when the engine is hot, check the temperature sensor… 2 If the fan fails to come on, first check for a fan blown fuse or triggered breaker. On older vehicle models, you may… More …

Why are there two fans in the radiator?

If the coolant temp got higher yet, it would kick on the 2nd fan as well for additional cooling. Yep, dual fans in the shroud that bolts to the radiator. At the moment the coolant temp won’t get over 192F, and when I directly observe the fans, they are both spinning, albeit at a very slow speed.

Where is the relay on a radiator fan?

The fan relay is often located in the engine bay’s fuse box, but the best way is to check your repair manual to find where it is located. Testing a 4 pin relay is often very straightforward. Remove the relay and give 12 volts to pin 30 and 85. Ground pin 86 and check if there is voltage coming out from pin 87.

Why are my radiator fans not turning on?

Unplug the coolant temperature sensor while the engine is running. This should cause the fans to turn on low then kick to high, IIRC. Typically when the engine computer loses the signal from the coolant temp sensor, it just turns both fans on high so the engine will not overheat. IIRC if you ground the gauge wire, the gauge should go to full scale.

Why do I need to replace my radiator fan clutch?

Fan Clutch The fan clutch is the assembly that holds the radiator fan to the engine and makes it turn. If this burns out or fails, you’ll need to replace it. There are springs within the fan clutch that can wear out or corrode over the years.

What to do if your radiator fan is overheating?

Check the coolant level in your engine. The simplest way to do this is to look at the reservoir in the engine. It will be marked with maximum and minimum levels. Always make sure the coolant level is up near the maximum level to avoid possible overheating. 5. Fan Clutch
