lower temp after-run pump switch F98

[Error404]

Anyone know the OE part number for the lower temp after-run pump switch. I have read it is from an LT van and also a Golf II / Corrado, but got no part number.

AFAIK it closes at 105deg, opens at 95deg

Cheers

I am after this also, I looked back though the archives but could not come up with a definitive answer

Dont use the LT Van switch if your car does any stop start use. If it's a weekend blaster it's ok

Volvo one:

FAE 3581 or FAE 35810, open 100ºC and close 95ºC. Standard on Renault 5 and Volvo 480. Works really well installed on on the Avant

nope probably like me the ****ing search function doesn't ever find stuff properly

[Jamo]

Nah comes up in searches, depends what keywords if you type after run or FAE it comes up quickly

Who is the best supplier to get these from?

[UrS4boy]

1990 90q20v (p/n 034 919 369 A) for $25 which measures underhood temperature (not coolant temp) and is set to turn on at 85 celcius and off at 80 celcius

That would come on too often, so thanks but not what I'm after.
The Volvo one Jamo quoted above looks the ticket

They have a different after run system based on air temp IIRC. The S2 sensor measures coolant temp in the water rail

Really.

Yes as someone suggested it before and they are not the same

You missed the sarcasm (sorry). My point is/was there is an alternative method of triggering the after-run pump using that air-temp sensor from an Audi 90 7A, mounted as Sean D. (quattro20V on the NAmerican forums) did.

Yes, it is an air-temp, not water temp, sensor but it does bring the after-run system on more often than the OE 110/97 water temp switch.

I installed the 7A sensor into my water manifold and while using the Vagcom recorded the switch activated the pump and fan at 95.8c. It shut down approximately 3 mins later at a temporary of 81.5c.

Appears to work very well.
