Check your relays and or fuses that go to your fan or fans ...also make sure you check your fans connections ...something in the wires can be faulty

Testimonial: "jump the 2 wires on the temp. switch conector and the fan runs fine. I purchased the coolant temp. sending unit at advance, and when I got home the receipt called it a radiator fan switch? looked just like the one I pulled out with just 1 wire, right under the distributor. I thought the coolant temp. switch was on the back side of engine by thermostat."

SOURCE: How do I diagnose a bad thermostat or temperature

You can remove the thermostat and put in a pot of water and boil it.(should open near the stamped temp on yours, 195f) From what you have posted, ti seems that you have a partially obstructed radiator core and at present, it's just bad enough for the electric fan to deal with it. (you can actually see that the temperature fluctuations happen when the fan is on and off) If you do not clean out the radiator, eventually the fan will not be enough to lower the temp and it will begin to actually go into overheat.

I'm not certain if this engine has coolant bleeder valves, but if it does, make sure there aren't any pockets, particularly around the sending unit. Something is fooling the computer into thinking that things are really, really hot.

check the 25 amp fuse that had fan rad on it . Check the fuses under the dash. Finally replace the fan switch in the head as it may not be communicating with the CPU to put power through the fan relay

to check if air in system, let cool down and remove radiator / coolant reservoir cap and systematically squeeze coolant hoses including heater hoses, you should see bubbles in reservoir as you squeeze hoses, continue until no more bubbles, then top up coolant to required level.

93 Honda civic vtec auto, does the coolant temperature sensor have a wire that goes to the coolant temperature switch sensor? one comes from the ecm. I assume the other goes somewhere?

here is better help

first off most cars, old, have 2 or three coolant sensor;.
1 for the dash gauge (dedicate) usually 1 pin sensor.
2: a two pin sensor, this is called (back then) CTS, coolant temp sensor, (this is the main ECU sensor ,if bad , ecu goes to horrid limphome mode. the ecu sends 5vdc to it and uses current flow
(measured) to read water temps, (and scale injections!)
3: an optional, A/C overheat sensor.

the drawings are all at any time you want too look

Radiator fan won't turn on at all

on the 92 civic you have 2 sensors for the coolant, one is a coolant fan switch and the other is a temp sensor. the fan switch tells the computer to turn on the fans at a certian temp. i would suggest replacing the fan switch which is located on the thermostat housing. if that doent work it could be the relay. I have owned my 92 civic hatch for 10 yrs and have done all the work to it myself. Also a mechanic by trade. Hope this will help you out

The electric radiator fan runs after truck is shut off. Will turn off after 30-40 min. Is this normal?

no it is not normal....have a repair shop check the coolant fan sending unit or the coolant fan relay...a bad sending unit maybe sending a false overheating signal to the fan causeing it to stay on or the on off fan relay maybe sticking make sure the jeep is not actually running hot the temp guage maybe reading the wrong temp

My honda civic radiator blowup what can be the fault

A radiator can blow up due to several reasons, the main and most frequent are:
  • A faulty Thermostat.
  • Low or leaking Coolant,
  • A defective or unplugged Coolant Temp. Sensor,
  • Defective Water Pump,
  • Faulty Radiator Fan Relay or blown Fuse.
  • Faulty Radiator Fan Motor or wiring,
  • Clogged Cooling System passage or Radiator.
  • Worn out (too soft) Radiator Hoses.
  • Wrong size Radiator Cap.
  • Dirty A/C Condenser Coil (the coil in front of the radiator)
Good Luck!!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Radiator fan not working

Hi. Check the bottom of the radiator or on the side, as you also have a temperature-sending switch. The switch must reach a certain temperature before sending a signal on to the fan relay.

The switch just screws into the radiator.

If you would like to contact me again about this or other problems, feel free to do so.
