Been having a hunt around and would just like to clarify....

If the coolent temperature sensor IS working correctly, will the fan operate stay OFF when unplugged?


Thanks, forgive my blonde moment

If you unplug the sensor, by default, the fan will be ON.

Cheers for that. Sensors obviously duff then. Never mind, more money to spend......

Does the fan work anyway, have you checked the wiring, hard-wired it, checked the relay???

Well mine has two radiator fans. One has seized (been like it since I got the car) and the other works as normal (ie when engine gets to operating temperature)

I cant work it out, it works when it should but when sensor is unplugged it makes no difference whatsoever to fan operation, just adjusts the engine idle very slightly

So it's registering being unplugged................... have you had any thoughts of replacing the seized one, as so many coupes are being broken these days.

I have but finding one is proving almost impossible, every pay day something else goes wrong so fan never got replaced, local scrappies have nothing, only one has a coupe and its stripped, no others have the right radiator so not getting anywhere with it yet.

Maybe only one comes on, the one that is seized.

Ah I see where your coming from. The one in question which is seized is the driver-side fan.

I have two fuses for engine fans; one under dashboard and one under bonnet, one under bonnet keeps blowing. Car overheated last month and when i replaced the fuse nothing changed, but when i replaced the a/c fuse, fan kicked in (not the seized one) really weird.

So, am I correct in thinking that the CTS is working correctly?

i thought there was stage one and stage two fans.

how about a set of slimline ones?

Hmm definate possibility. Ive only ever needed the one fan. Seems to cope absolutly fine so not incredibly bothered, though everyone in portsmouth hears it kick in :)

i've had mine running on both a few times recently, they do move a lot more air than you think!

Thanks for the advice, on that note I think I'll splash out this friday on a new fan.

can a faulty coolant temperature sensor cause hesitation and misfiring when the car is cold / reaching temperature?

yes, very much so

does anyone have a guide or picture of where the sensor is located for replacing?

i replaced my temp sensor resently if you look at the with the front end of the engine (end with cam belt) the tempature sensor in on the back right of the engine, its screwed into a cast t junction sort of thing which is bolted to the engine its fairly easy to see on a 200

cool will have a look later on does anyone know what resistance the sensor should be reading so I can see whether my original one is faulty?

not on a t-series its not.

look for the thermostat housing, there are two sensors in the side of the housing, one is a single pin used for temp gauge reading, one above it (2 pin and brown connector plug) is the one you want.

mine is a 216Sli Honda engine
