Question about 1992 Honda Civic

1 Answer

Engine is getting hot and radiator fan will not come on- would like to test the fan connector plug with jumper wires or the fan temperature switch, the sensor for the fan and the cooling fan relay - do I need a diagram and where can I find one online?

You should have a check engine light on if your coolant temperature sensor is bad. It could be your fan relay. It's position should be located on your fuse box cover(s). To check the fan itself, unplug it and notice that the black (or darkest) wire is the ground, so you can hook your jumper wire to any metal part of the car. The other wire goes to the positive terminal of a car battery. Good luck.

Motor fans not turning on even when I turn on a.c it still doesn't how can I fix


What is year--make and model?
If your talking about radiator fan/s, how hot does the engine get in degrees F? Some fans won't come on till about 220 degrees F.
You might be able to test the fan using jumper wires from the battery for voltage and ground, run the jumpers to fan connector, see if fan would run.
Can you check applicable trouble codes? I could look up wiring for fan, but, I need year--make--model.

If bypassing the sensor in the car allows the fan to start, then I would say the issue has to do with the sensor. I've heard of them getting an air pocket around the sensor and preventing the fan from coming on. Maybe the contacts aren't making up in the connector? Corrosion could be causing an issue. Maybe a loose wire that opens the circuit when plugged into the sensor.

Cooling fan wont come on car running at a high tem


You could verify fan motor is good by using jumper wires from battery to the fan motor. If the motor is good, you will probably need a wiring diagram and at least a test light to start checking the fan circuit. There will be a cooling fan relay that when signaled, will send power direct to the fan. The signaler to relay to turn the fan on may be the engine computer when the coolant temperature sensor tells it engine is getting too hot- or it may be signaled on by a fan temperature switch mounted in the radiator. When coolant reaches a set temperature the switch closes contact, and the relay is energized to pass power on to the fan. One could pull the relay and with key on, use test light to probe the terminals where relay plugs in. The power feed for the fan should light up the test light on one of the terminals, verifying power is still available to turn the fan on. Next one could check if the signaler to turn the relay on is working.
See? So you do need a wiring diagram to see how the circuit is wired. But the first step is to verify fan motor is good. Good luck, Nigel.

please follow this steps and fix it.
A fan failure, or a failure of the fan relay or control circuit is bad news because it can allow the engine to overheat.
Five things may prevent an electric cooling fan from coming on:
  • Defective temperature switch or coolant sensor
  • Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan)
  • Failed fan relay
  • A wiring problem (blown fuse, loose or corroded connector, shorts, opens, etc.)
  • Bad fan motor
ELECTRIC COOLING FAN QUICK CHECKS.
One way to quick check the fan circuit is to start the engine and turn on the A/C to max. If the fan runs, the fan motor, relay, fuse and wiring are all okay. But this test doesn't show if the temperature switch or temperature sensor and PCM are energizing the fan when coolant temperatures are high.
To check the temperature at which the fan comes on, turn the A/C off and keep the engine running until it reaches normal operating temperature. Most fans should come on when the coolant reaches about 200 to 230 degrees. If the fan does not come on, something in the control circuit is defective. Resistance checks should then be made on the temperature sensor or switch, and a voltage check on both sides of the relay (you will probably need a wiring diagram of the fan cooling circuit on your vehicle to identify the relay terminals and wiring connections).
The fan motor itself can be checked by using jumper wires. Unplug the wiring connector on the fan, and use the jumper wires from the battery to route power directly to the fan. If the fan motor is good, the fan should spin at normal speed when supplied with 12 volts. Noisy bearings or a slower than normal speed would indicate a worn motor.

2000 radiator fan test, is there any way to test the fan before o get a new one


check cooling fan fuse or fuse link.it all is good. fan relay or engine coolant temperature sensor.could have ECM FAULT it controls coolant fan relay and coolant fan.code scan for ECM FAULT YOU WILL SEE CHECK ENGINE FLASH IF PROBLEM IN THE ECM.but check cooling fan hot wire it using jumper wires to battery.if fan okay replace engine coolant temperature sensor.

I have 1999 VW Beetle 2.0 have change all cooling fan parts all new relays sensors fans control modules and the temperature dash light keeps showing hot what could it be thats going wrong


connection to radiator fan switch could be bad.

If I take out the connector from the fan switch (thermo switch/fan control switch) that light acts just as you described.
So check the fuse box on top of the battery, take out the fuses and make sure nothing is melted. Now check if you are getting power to the switch connector. red wire is hot wire, 2 striped wires can be used as ground. Make use you get around 12 volts, not mV.

if you got no power there then try checking continuity in the wiring... you need power there to make thing work :D

learning from experiencing.

Installed B18 used engine now the radiator fan won't come on


If you used the sensors that came on the used engine, replace the coolant tempertur sensor. this should fix your fans

Car will overheat while at idle


yes the head gaskets leaking on modern aluminum head engines is all to common. never overheat them, if they start to get hot shut it down and find out why, it can of course be the fans and plugged radiators or faulty thermostats but sounds like in your case the head gasket is leaking and combustion gas is entering the cooling system and this causes an overheat

It starts fine, runs good until the engine heats u...


Check to see if the radiator fan is coming on when the van gets hot.If it does not then on a 2.6 liter engine.look on the bottom part of the radiator on drivers side for a fan switch that could be bad and not letting the radiator fan to come on. On a 3.0 liter engine the coolant temperature sensor is screwed into the thermostat housing. And on a 3.3 liter and on a 3.8 liter engine the coolant temperature sensor is screwed into the front cylinder head. Anyone of these can cause the van to run hot and eventually die with no restart until the temperature has cooled down. Check the fan first with two jumper wires from the positive/negative post to the fan connector on a 2.6 liter engine (positive wire to open pin on plug,negative wire to insulated plug side. On all v6 engines hook jumper wires to motor. To the left side will be positive and negative to the right. Do not let both wires touch together while testing. If motor does not respond to direct wiring then replace it. Another thing to look at is the catalytic converter on van. Check the exhaust flow when the van is running cold and again when it gets hot. If the flow starts to slow down when the van gets hot then remove the converter(plugging up). After doing that run the van again to see if the van runs ok. Hope this will help you.

Radiator fan not working


CHECK FUSE AND RELAY.IF ALL IS GOOD.HOT WIRE COOLING FAN USING JUMPER WIRES.USING CAR BATTERY.IF FAN RUNS.ITS GOOD.IF FAN DONT RUN.REPLACE FAN ELECTRIC MOTOR.ALSO SCAN IT. TO MAKE SURE COOLANT TEMPERATURE SENSOR IS NOT OPEN.MAKE SURE ENGINE COOLANT TEMPERATURE SENSOR AND COOLANT TEMPERATURE READS SAME ON SCANNER IF NOT REPLACE THE COOLANT TEMPERATURE SENSOR. SEE IF COOLANT TEMPERATURE IS BAD THE COOLING FAN OR FANS WONT RUN.
