Hi there, does anyone knows the part number of radiator fan switch? Also where exactly is it located? is it the one which connects to fan and you can reach it from top? any pictures info advice would help.
Thank you lads

What car and engine is this for ?

Its a Coupe 2.0 16v ACE engine. been looking at parts numbers on your s2 site. i think they differ slightly. so just want to make sure im getting the good one as nowhere is accurate picture. cheers

If it's like the 2.0 8v, it'll be down the bottom of the radiator on one side or other. it has a plug on the end of it and unbolts with a big open spanner (19mm plus iirc) Made of brass so easy to spot, but don't forget to put a washer in when you replace it. You'll lose a lot of coolant when you remove it so have a tray underneath so that antifreeze doesn't go everywhere! Don't know part no, sorry.

Hello mate,

found it today.it is on the passenger side bottom corner.easy to reach from bottom but havent got spanner bigger than 15- bugger Confused

so when i remove it is it all coolant which will bleed? just hoping it is the switch which is causing fans not starting, iam not a big friend with wires and fuses:} thank so much for this post bud. will keep updated how i get on but if someone knows the part number it would be even better

893 959 481 for a 2 pin
191 959 481 C for a 3 pin

N 043 808 C is the seal

pretty sure it's a 29mm spanner for removing it

I think i used one of them plumbers wrench's on mine. Very Happy

dont need to be in super tight and no need to drain coolant if your quick, just make sure its cool when yo do it.

yeah got one from ebay for 12 quid incl washer. getting new belts done next week so will change it with water pump once the coolant is out. hopefully the switch is the thing what causes fans not kicking in.... Confused

3 pin radiator fan switch old

you should test the system before stabbing in the dark.

ignition on, disconnect the rad fan switch. use a bridge wire to join two of the wires together in the loom and verify the fan runs

Lol did it this afternoon and bang fans are working. Just wondering- on the switch i bought reads 84 degrees. Does it mean the fans wil kick in at 84? that would mean they will be on all the time Confused

thanks mike

Have you got a link to your Ebay special as it's more than likely the wrong one

Posted: Tue Aug 16, 2011 4:44 pm

argh hi mike i send it to you tomorow iam at work and my work pc is webmarshalled to ebay Evil or Very Mad

why do you reckon its a wrong one?

Posted: Wed Aug 17, 2011 7:14 am

84 degrees should be a clue.

Your thermostat opens at 87 so why would the fan start running before the thermostat has reach operating temperature

good question havent thought about that. anyway here is the link from my ebay http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=170515595672&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

hi luigi-3. the thermostat is correct, and the thermoswitch has 84 on it because it switches the fan on at 95 and off at 84 , its a two stage switch for low and high speed fan and it also comes on at 102 and off at 91 for high speed. had a look at the ebay links and seems to be right part numbers and spec.

that's the correct switch
