Re: radiator fan for honda civic 1988 not switching on
There is a temp switch located on the radiator ..with a quick realease plug..replace the switch or get the old switch from the old rad and try it. be careful..keep the cabin fan on full hot to relieve heat off the engine..and top upp coolant.

it is possible that when the water pressure rises in your radiator, and the radiator shoots the water into the reserve tank, that hose is not properly put on(happens alot when changing radiator) and the coolant leaks rapidly through there. another thing i suggest is observe your fan behavior. fans usually are only supposed to turn on for a couple of seconds, around 10 or 15. park your car, and let the car reach normal operating temperature. when the car starts to over heat, check to see if your fans turn off at all. if they do, then it is most likely the tw swith,or the water temperature switch. if you notice the fans stay running, then i suggest obesrving your hoses and replaing any that spill coolant because even a pressure test on your cooling system can miss a small pucture in a hose, which after a while will cause your coolant to leak, and your car to overheat. hope this helps. if still nothing, drop a comment and ill help you out somemore, but for now, this is the practical thing to do. hope this helps, goodluck.
verify the plug of the fan and the fan switch located in termostat housing, if all are pluged in remove the conector of fan switch and short it with little piece of cable, if fan turn on replace the switch! it cost around $20. if the fan no turn on when short the conector verify if the fan conector have 12v if have it changer the fan motor if not check the fuse.
Sounds like your electric cooling fan(behind the radiator) is not functioning. The thermostat might not be working,making the fan
not come on at all. I once put a toggle switch in my dash,when I had
an old CRX, just to turn on the fan, or it would overheat.
hi 1st u have to replace condenser fan and radiator assy , it will solve your problem , cause due to no coolant radiator fan is not working and cause of engine overheating a/c system got trip . replace both condenser fan and radiator and put new coolant. thanks.
you know the fans are ok most honda have a two terminal switch at the right corner bottom of tthe radiator if you put a jumper across this terminal the fans should kick in, this indicates that the coolant temp sensor is bad replace it, secondly some honda have a temp sensor located right on the thermostat housing and you can disconnect the wire and just ground the wire and the fan should come on so replace the temp switch last thing to check for is coolant leak around the readiator seem i mean the edges the radiator being fiber glass may have hair crack through which antifreeZe keeps leaking out the only suggestion for honda is to replace the radiator.
If it's an auto, remove the cooler lines. Remove the upper and lower hoses. Remove the top bolts that attach the radiator hold down to the core support. Unplug the electric fan harness's and pull up on the radiator. Switch the fans with it out of the car to the new radiator and install in reverse of removal.
