All you have to do is run the car untill the fan turns on while waiting touch the top of each relay with your fingers, and the one that clicks will tell that it is the relay for the fan.

Have you confirmed the water pump is working? If the car is moving at 10-20 MPH you should have enough air going across the radiator to prevent overheating in a moderate climate at this time of year.

Where can i find the fuse for the cooling fan for a 2000 mazda 626


There should be two fuses for the cooling fan relay in the main box near the battery.
You could have air pockets in the cooling system which would affect the temp sensor.

Where is cooling fan switch located on 1999 mazda 626 2.0L


Cooling fan switches are located on the bottom of the radiator. These often control a relay that runs the fan. If the fan is not working, it could be the fan that is faulty. Make sure that the fan blade will rotate manually. Try applying +12v directly to the fan to test that it runs.

My mazda 626 2002 is overheating we have replaced the resevoir and the caps and its still doing it its fine when driving than when you come to an idle it starts to heat up again and than will go back down...


it sounds like the radiator fans are not coming on. Check the fuses and relays for the fans. there is a temperature switch to control when the fan(s) comes on. If you have AC then the fans should come on when you turn on the AC.

I have a 1996 Mazda 626, the check engine light came on and the car has been redlining the the temp gauge. I got the engine codes which are: p0117 and p0421. Does anyone know how to solve this problem?...


The cooling fan must run or the car must be running into the wind to keep from cooking the engine. Physically turn the fan to see if it turns freely (cold engine). The computer reads coolant temperature and trips the fan relay on when normal temperature is reached. You need to read the control voltage at the relay to determine the problem. Possible bad temp sensor.

2001 Mazda 626, intermittently overheats - especially but not always when not moving


Sounds like a fan issue...

Maybe a fuse, could be the relay.

Start the car and let it run at idle while not moving... if the car over heats and the fan never kicked on, then you need to figure out why it isn't kicking on.

to check the fan you simply need tro run a direct lead to the battery..if it doesn't come on then the motor is probably burnt up, if it comes on with a direct lead, then you have another issue.. fuse, relay, or thermostat.
