Did you check the coolant tempurature sensor.

    no alarms on a scanner for that problem should i replace anyway?

    yes you should to be safe. a check engine light will not come on for this, not usually. I dont think the fans are getting the proper tempurature to turn fans on. as long as the wiring and fans are ok. replace coolant tempurature sensor. good-luck!!

Even with a fully charged battery i need to use a battery pack to start the van when it does start the cooling van comes on for a minute then goes off and that continues


Check rear AC in van and turn it off. Most vans have dual AC. Even if the front AC is off, the rear is still usually on and some vehicles have the cooling fan and condenser fan run together to help with cooling. Check relay and fuse also.

Car over heats fans dont come on


Check fuse for cooling fan, check temperature sensor functioning for cooling fan, check relay for the fan (if you have one), check cooling fan motor circuit with resistance check (should read low Ohms, less than 2 Ohms beacause the fan is a powerful motor with 10-20 Amps).
If everything is measured O.K. you should check the wiring. Disconnect the connector at the cooling fan motor, connect a test light to the harness from the car (not to the motor side) and run the engine. Watch the temperature gauge and before you the boiling (overheating) the bulb should lit up. If not you should go back with this test step by step to the relay. The relay can be tested if you can find a same one on your relay board and swap temporary (e.g. swap the AC clutch relay with the cooling fan relay)

98 Honda civic cx over heating when stopped in traffic - I went thru cooling system, replaced hoses, thermostat, fan, radiator cap. After that stated to overheat on freeway after about 40 miles. pulled...


Unplug the fan on sensor. It should have one green wire and one black wire. Use a paper clip and jump the two wires. Turn the key to the run position, the engine does not need to be running. Does the fan come on? If not check the green wire for 12 volts and the black wire for ground. If there is no ground than run a new ground wire. If the is no power check the heater/air conditioning fuse in the under dash fuse block. If there is power and ground make sure both the cooling fan fuses are good and both the cooling fan relays are good.

1989 Toyota Corolla 2bl Fan not coming on to cool radiator


You would first need to jumper the relay to make sure the fan can run, and then check the relay circuits for power and a ground signal from the computer. The computer grounds the relay when the fan is needed.

My cooling fan will not turn on. What could this be? I had someone tell me the water pump, but it does not leak.


Step 1:

This cooling fan circuit has 2 cooling fans and 2 cooling fan relays, both cooling fan relays are located in the BJB (battery junction box, underhood fuse box) there is a low speed or main cooling fan relay in cavity location # K-46 and the high speed relay is location # K-47! Also check the main cooling fan power fuse # 2 in the same BJB, The fuse is a MAXI-FUSE (large one) it is blue in color and is rated at 60amps!

Step 2:

Also check the coolent tempature sensor thats what signals the fan to turn on.

Step 3:

Do the fans turn on when you turn the a/c on. if not may have bad fan motor

Engine heat get high & whats kind of fan radiator suitable


i am familiar with the car and the problem . the best thing to do is go to the local parts store and ask for an adjustable thermostat fan switch its about 40 dollars you wire it to the battery the fan and a ground mount it near the battery start the car and adjust the knob to the desired fan turn on temp . to fix the setup you have there is a fan turn on temp switch on the passenger side head toward the rear should have one wire on it that grounds the relay on the radiator support . 87 should have one fan one relay sometimes the relay burns and melts the plug you have to buy a replacement plug from a parts store along with a relay so to test it ground the sensor wire with the key on and fan should turn on if it does that's the problem you could also buy a low temp one from summit racing.com the fan will turn on sooner if it still wont turn on the relay is the next culprit check if you have power and a ground with key on at relay plug if you do the relay is bad change it . hope this helps
