I've noticed lately that my cooling fan has not been coming on when I've been idling for extending periods of time or I've been in heavy traffic. While the car hasn't gotten above 210 deg, this is the second engine in this car (first one blew a head gasket and cracked a piston), I would like to keep the motor as cool as possible. I've checked the relay, the fuse, the fan motor, changed the temp sensor and the sensor connector and it's still not coming on. I know that many state that the fan is not supposed to come on until the radiator is nearly boiling, but I was thinking of installing a toggle switch to be able to manually turn it on myself.
I was checking the fuse/relay panel to make sure with a grounded test light to make sure that it's not a wiring problem. According to the Haynes manual the number 30 terminal should have power all the time, and it did, but the 85 terminal should only have power with the car switched on, but the light indicated it was getting power with the car switched off. Any one have an idea what this is indicative of?
I've got a 97 2.4, my fan doesn't kick on until it's really hot. Instead of doing the fan switch mod, I added a pusher fan in front of the rad with it's own relay/switch.
Does your fan come on when you turn on the AC?

I wished I could tell you, but my a/c does not work. I have a leak and it doesn't have enough freon in it for the compressor to even come on.
Is it a good idae to put a manual switch in, wont affect anything?
My car is the same way; fan never comes on, and sometime she gets way up there in temp.; i would not mine having a switch to flick it on myself.
Is this hard to do(install of the manual switch?

It's fairly easy and won't hurt anything. I've killed my battery twice now by forgetting to turn it off though.
