968 cooling Help !!!!

[phib]

Right so after three years of 993 / 968 heaven I decided to sell my 993 to buy someting else (not bought yet) and having had no issues with the 968 decided I would run it for a bit everyday the 993 went on friday so what happens to day ......

Yes the bl**dy 968 starts overheating !!!! Now I am convinced that its probably the fan motor but I am not sure how to check things I have done so far

1. Checked fuses both ok

2. Listened for fan and raised temp to 3/4 on the temp gauge fan does not cut in.

So either its a faulty thermostat or the fan motor has gone

Is ther anyway ofd checking these

Thanks

If the fan motor wire is easy to access and has just two wires try connecting it straight to 12 volts. If it works then look for a switch fitted into the radiator somewhere - if this has 2 wires try connecting them together and see if it makes the fan come on - if it doesn't then it probably needs a new switch.

I haven't done any of this on one of these cars, this is just back to basics stuff that I'd try. If there are more wires or you are unsure then seek expert advice - probably why you asked here in the first place I know but the above might be useful in the meantime.

Had the same on my old S2

It was a faulty temperature sensor

It is usually the temp sensor in the radiator, but take care replacing it. Don't use a wrench or spanner or you can crack the plastic end cap - use a deep socket and don't overtighten.

You will probably have a 3 pin radiator switch but you can test the fan by unplugging it and just using 2 wires from a battery.

If that does work link accross 2 off the wires in the plug for the switch and see if it comes on.

take a nice deep breath, remind yourself that occasionally things go wrong with a 12-14yr old car and give thanks to whichever deity you defer to that its not a wiring loom or a door check-strap

[phib]

Its ok I have had issues with the loom and check strap's already !!!

[phib]

Well the fan works !!!!!! so now either its the temp switch or the wireing, now normaly this would go to the garage but I cant get it booked in in time and its having its cage fitted on thursday !!!

So where does the temp switch live and what does it look like ? Oh and how do I change it ??

Thanks

Friend of mine had a problem with his 968 cooling fan, turned out to be a crap earth connection that kept blowing the fuse on the fan.

Ask/search over on 968uk.co.uk if you havent already
