#4: Re: Hdi engine temp and fan not working Author: Seabook, Posted: Sat May 14, 2011 12:00 pm ---- just follow the general rule to check if the fan is working or not
#5: Re: Hdi engine temp and fan not working Author: eddrj, Location: BerkshirePosted: Sat May 14, 2011 12:01 pm ---- whats that?
i mean hasnt come on at really high temp or when i put air con on still nothing.
#6: Re: Hdi engine temp and fan not working Author: Seabook, Posted: Sat May 14, 2011 12:02 pm ---- like you said check the wire first.
#7: Re: Hdi engine temp and fan not working Author: eddrj, Location: BerkshirePosted: Sat May 14, 2011 12:11 pm ---- sorry for being real stupid here but which wire is it ?
#8: Re: Hdi engine temp and fan not working Author: eddrj, Location: BerkshirePosted: Sat May 14, 2011 12:42 pm ---- holy s**t dont think air con is working either is that why ? or would not make a difference ??
Also just seen there is a white connetor plug hanging down at bottom of radiator is that for air con compressor because had it done few months back where does it go ?
#9: Re: Hdi engine temp and fan not working Author: perry081064, Location: staffordshirePosted: Sat May 14, 2011 12:54 pm ---- first off you need to check if the fan works ( 12v directly to the fans power plug. )
if this spins the fan, the problem is elsewhere, you need to check the wiring around the relays for rot, and check to see if both fan relays work too.
mines got a similar problem but havent had time to sort it yet, however im lucky becouse my temp rarely goes anywhere near 80 , even on a hot day.
#10: Re: Hdi engine temp and fan not working Author: eddrj, Location: BerkshirePosted: Sat May 14, 2011 12:57 pm ---- ok thanks ,
yeah mine only goes up really high when in traffic which is normal, but then fan meant to kick in and mine doesnt.
#11: Re: Hdi engine temp and fan not working Author: eddrj, Location: BerkshirePosted: Mon May 16, 2011 1:50 pm ---- just had my mechanic fix it it was corroded relay controls and fan resistor open circuit but its still not coming on lol what the hell ? is it the cold air outside ? even tho car temp said 90 didnt come on is it just wait for a hot day ?
Thought they where meana come on certain temp.

fan should kick in around 20 seconds after you press the aircon button.
you should hear the relay click the moment you press the button.
( this should happen even if it needs regassing too )
how much did he charge you ?
... and obviously he hadnt checked the work after completion, otherwise he would have known its not working.
#13: Re: Hdi engine temp and fan not working Author: Steve206, Location: UKPosted: Mon May 16, 2011 2:28 pm ---- The fan should kick in at about 95 degrees. I wouldnt worry to much on a HDi, they dont run as hot as a petrol engine anyway. Sounds like your mechanic fould the problem anyway, a common fault.

... so the fan for the aircon is working then ?
as i said in my last post , the fan for the aircon should still work within around 20 seconds, if its not , isnt there still a problem ?
#15: Re: Hdi engine temp and fan not working Author: eddrj, Location: BerkshirePosted: Tue May 17, 2011 12:36 am ---- ok not sure my air con works tho so will the fan still come on ??
yeah il try and get it to 95 see if it comes on .
Im well confused if still doesnt come on after that give up , got mot and tax in 3 weeks il concerntrate on that now , car has never overheated anyways like said not so important on a hdi as they dont run so hot.
