2. How to Fix a Cooling Fan in a Car in 4
Simple Steps?
• The cooling fan in a car is activated whenever
the engine temperature rises above a certain
temperature. The fan doesn’t run all the time.
Typically when a vehicle is driving at slower
speeds or stuck in traffic it will be needed.

3. Is your car’s temperature gauge
getting too hot?
• There’s no need to panic. If the temperature gauge
needle moves into the red, this usually means a
problem with the cooling fan. If this happens while
you’re driving, you should pull over as soon as possible.
• The cooling fan will need to be fixed quickly, as
continued driving will cause the engine to overheat
and lead to a lot of trouble. You can easily identify and
fix this issue yourself. There are four failure points that
need checking.
• Note: the following are general instructions. Check
your owner’s manual for further instructions and
precautions.

4. 1. Test the motor
• Check under the hood, locate the cooling fan and see if it is
spinning. If it isn’t then something is wrong with the fan system.
• Cooling fans are simple DC motors. You should start by testing the
motor. You should see a cable coming off the motor. Follow the wire
from the fan motor towards the engine, until you get to the plug for
the fan connector. Gently unplug the cable from the connector.
• Get a hold of jumper wires for testing. Hook up one end to the
positive and negative terminals of your car battery and the other
end to the terminals on the fan motor. It doesn’t really matter
which way you connect this.
• CAUTION: the fan blades are sharp. Take all necessary safety
precautions.
• If the fan motor doesn’t start working, then the problem is with the
motor and you just need to get a replacement.

5. 2. Check the fuse
• If the motor does come on then the problem
is somewhere else. At this point we know the
motor isn’t getting any power. So check the
fuse to make sure it hasn’t blown (it should be
continuous). If the fuse has blown, then it
needs replacing.

6. 3. Check the temperature switch
• The fan gets its power by a switch called the
cooling fan temperature switch. The position
of this switch depends on your car. Check your
car manual to locate it. To check it you need to
unplug it, ground the terminal from that end
and take the other end of the ground wire to
the negative terminal of the battery. If the fan
starts working, then all you need is a new
sensor for the cooling fan.

7. 4. Check the cooling fan relay
• After all of that, the fan may still refuse to
work. There is one more thing left to check,
the cooling fan relay. Go to the fuse box which
should show you where the relay is. Unplug
the relay and just replace it. Over time these
relays can stop working and simply need
replacing.
