Overheating

[alank950]

My van was overheating and i did not hear the radiator fan comming on which tells me it could be the fan sensor switch.I am having trouble finding one of these although i think i located one on ebay from Latvia..does anyone know of any uk dealers who stock these...van is 1985 1.9D

Easy to change, even I can do it.

Have a look at this page also

Thanks...i havent had a chance yet to have a look but from what i have read the sensor is located at the top of the radiator (although the link you posted suggests it at the bottom right) this was a design flaw in VW design of these ..i will know more when i have a look at the radiator over the weekend..thanks for the links

Bottom right - this is the hottest zone on our radiators.

Ok i tested the sensor connector and the fan did come on so its the sensor thats faulty.I did notice though that the fan is only comming on at one speed when i jump the connector weather its full speed or half i dont know...any ideas why this might be?.I will check the wiring on Sat when i have more time ,i am thinking if the fans working it should be working on the two speeds..

OK,

When I did this, only had one speed, what i did was remove all the earth crowns from above the glove box, gave them a clean, put them back on and tested again.. worked. Thats what I would do first, then dig deeper if this doesnt work.

Just to to add, if the fan is not noisy and a gentle spin it will be the low speed, if its pretty darn loud then its the high speed one

Earth Crowns?...i assume these will be green wires with connectors

[crazyhorse]

The earth crowns are on the passenger front behind the fuse box, and the left attaching to the bodywork. In the footwell area

Its a a small circle should be 2 of them shaped like crowns. The have variousconnections going to them providing earth to all your electrical conncetions. Should be about 5-6 on each one.

If there is a leak in the windsceen, water runs down and sometimes rusts the connections. Mine were ok once i pulled them out 1 by one and checked them over

Don't assume green is earth, brown is. Also black isn't neutral/return/earth it is usually live/positive on German items.

I just watched a video of a guy who replaced the earth crowns with what he called a bus bar or earth bar

[alank950]

There are two types available 100amp and 150 amp..migh be worth while if the crowns are corroded
