My 1993 Cavalier V6 radiator fan runs almost all the time, even when the engine is cold, and I suspect the temperature sensor. However, the sensors I have located online do not look like the ones I can see in the crux of the 'V' on the transmission end of the engine. Can anyone tell me where the radiator fan temp sensor is located?

On most 4 pot cavs it's screwed into the radiator itself somewhere

It's the same on the V6. It's on the drivers side of the radiator, mid-way down on the side facing the engine.

Many thanks for the swift responses. I've now located the sensor on my radiator and confirmed it looks like the replacements I've found. Don't know why I didn't think of it being on the radiator but there's so much stuff crammed into the V6 engine compartment that it's difficult to see a lot of of items. Thanks again.

Yes, there isn't much room to work around on those V6 lumps! I managed to replace mine with a bit of hassle, obviously removing the air filter housing helped me a little I think, I had the same problem with mine, but with mine, it was the resistor pack which is mounted on the other side of the radiator, it's like a ceramic block, those are hard to find. The fan ran as soon as it warmed up a little and wouldn't shut off so I had to disconnect it on short trips unless I was stuck in traffic.

I've often thought a fan overide switch could be a good idea, just means accomodating it somewhere on/under the dash.

No problem glad to help

Easily done via a relay.
If you don't have air con, you could always fit a switch in one of the blanks.
Or even one of the seat heater switches.

I have done a thread on this somewhere, although I probably need to re do all the images after fotobucket pulled the plug and I deleted my account - pah!
