Done a search but no luck. My valver is overheating in very slow/ stationary traffic. But fine when moving. Had new rad and coolant oil and oilffilter. No gunk on the oil cap and not looking coolant. Any thorts as to what it might be?

Temp sensor? Does it cool down when driving? (drop below 90)
-
Drops back down. Bit stays at 90
-
Do the fans come on? There's a video on YouTube to check if working on both speeds
-
Yeah check if the fan is actually coming on. If it isn't try shorting it to see if it's the fan or the fan temp sensor at fault.
-
I shorted the fans when I changed the inlet mani. Thinking about it I've never heard the fans come on before :undecided: guess um gonna be checking that next. Cheers
-
Start it up from cold, and keep your eye on the oil temp on MFA, my fans come on at 82 - 84 oil temp on my 8 valver and on me VR6 I think it about 86.
Check to see if I comes on and if the oil temp rises and no sign of fans being on, then you have a problem with the fan module. But don't let it rise anymore than 90.

No worries, cheers for the link! Come to think of it,when I changed the rad, I had trouble getting that plug back in, so it might not be connected properly, will test it out tomorrow.
Cheers :afro:
-

Right, so done this test, and the fans don't come on. I also earthed the sensor that's on the inlet manifold, and I can hear the relay in the fan switch under the expantion tank clicking, and the fans twitch but they don't come on. What's wrong with it?

Well then if thats the case i think you'll be needing a new radiator fan.

But i think your fan motor has gone bust. Try the switch first its cheap to replace, but if that doesen't solve it, then its defo the fan motor :wink:
-
Thanks for all the help. So a new set of fans it is then? :sad:
-
Also there's only one fuse in the fan control unit. Is that normal?

Is that for a 8v or 16? Or are they the same? Il order one now. Hopefully it ain't the fan motor
-
I don't know if it's for 8V or 16V, but it should be same for both.
On second thoughts it can't be the switch, becuase your giving direct live to the fan motor and if they ain't working then you have problems with the fan motor, which is prob burnt out.

It knows you dont love it anymore..
-
I do love it, but I hardly ever get to drive it like it's ment to be driven, and I can't keep pouring money into it that I'm nit going to make back when I do sell it.
-
Right. I've got a New fan motor. I theory before I go ripping the front of the car off il test it. So I plugged it in. Then I did the sensor bypass test again. And it still didn't work! Should I look at replacing the fan control switch? Help!
-
so you tried testing the fan like in the youtube video and it worked fine? I tested mine earlier and the paperclip heats up really fast,...(gotta be careful as I burned my fingers!)
If that is working as in the video then the fan motor is ok...
Then at least the fan is alright..!
-
Tried that test and it didn't work, with both fan motors I have, which leads me to think its the FCM
-
Right, drove it home, then had to stop in the village :wink: to post something, after I parked and turned the engine off the fans came on! :huh:
-
They do run on if its hot after you switch off.

I know but they didn't work at all. I spend money on parts then they go and work!
-
Do you have any idea how they came on? mine work when i bypass the switch, but ive tried 2 seperate switches and the fan still doesnt work at temp?
