Title: Radiator and Oil pressure switches
Post by: Jetta90 on June 09, 2021, 08:22:38 AM
OK so I have a 1990 1.8 8v jetta (carb, engine code GU)

I want to get some new bits but not too sure which ones I need.

I want to get new radiator fan switch and oil pressure switches but places like GSF website just leave me more confused as to which colors or how many poles mine should have..

Don't have the car at the moment so can't even go pull them out and check.

Send help!!

Hi,

Unfortunately, you'll definitely need more information before you go buying.
Your fan switch is almost certainly a 3 pole switch (one earth, one low speed, one high speed).
But you'll need to identify which oil pressure switch you need, as there are two on the car, one high pressure and one low pressure.

There are early and late fan switches, the early ones same as MK1 and just have 2 poles. Later have 3 as that includes the ability to have the fan overrun with the ignition off for cool down after switch off. As a 1990 you'll have the later fan switch.

Oil pressure switch, I wasn't aware there were multiples, but sites like this http://www.oemepc.com/vw/ are good for getting part numbers for specific models/years/engine codes with the OE part no it's often easier to search or cross reference and get the right part.
