Fan for radiator not coming on - 1994 Mazda Protege

1 Answer

First off check your fuses and find the wiring harness for your fan and examine it. Look for any broken wires, burnt wires etc Next, grab a test light, unplug the harness from the car and test to see if you have voltage going to the fan. If you do and the fan doesn't work, the fans probably bad. If no voltage, then you may have a bad relay or temperature switch. Also, check your coolant level. That may be affecting your level of heat. If its the blower fan for the heater, do basically the same thing. check it to see if there is voltage going to it.

What is the fan in front of the radiator for? My 1996 corollas fan does not work, do i need to pull the radiator to replace it?


that fan is to help cool radiator when needed although it doesn't usually turn on until the car coolant temperature is around 200-220 degrees depending on where u live this time of year the coolant may never get that warm to need the fan to come on
as far as having to remove the radiator you might have to remove radiator but usually u can just remove radiator mounts and tilt the radiator forward enough to allow fan to come out

One of my fan is not working 1999 Honda Accord


Which fan is not working, A/C or Radiator? Check fuses, if good disconnect fan plug, direct wires from battery to fan to check fan, if fan does not work change. If fan works check water temp sensor for radiator. A/C fan only comes on when A/C is switch on. Like wise radiator fan only comes on when water reaches a certain temperature.

The fan on the radiator doesn't always come on, and there is a slow leak of water coming from the fan. What do you think is the problem?


Chances are that the radiator behind the fan has a leak (fan has no water supply so can't leak water). Have the system pressure tested to find the leak. As far as the fan not coming on, it is also likely that the sensor that controls it is sometimes deprived of coolant and therefore not reading properly (because of radiator leaking)
Therefore, have the radiator checked, repaired or replaced, then, if the fan still mis-behaves change the coolant sensor, check fan relay and connections. If water got into the fan motor, it may have caused a problem but the motor is supposed to be sealed and that's doubtful.

I just changed my radiator,thermostate.But it is still overheating.I don't see any smokes,but the gauge for the temperature above normal.What should I do?


The radiator fan may not be blowing.
Idle car with parking brake engaged.
Turn OFF Air Conditioner
Pop open hood and look at the radiator fan.
It is not spinning.
Turn ON Air Conditioner and look at fan.
The fan MUST be spinning.

Replace the "Radiator fan" relay switch.
Check primary fuses and replace as needed.

Over heating


Check fan thermostatic switch. Could be in the radiator or by the upper radiator hose on the engine. The thermostatic switch is what turns the fans on when the engine gets hot.Fans are supposed to come on when the A\C is on.
