After Run Cooling System Fixed

[Billman]

and yes i have changed rad fan sensors with the rad in the car, it's tight but can be done, better to do it from underneath and the new ready to go straight in otherwise you end up loosing all the coolant, mind you good time to change the coolant if required.

You mean also the After run cooling Pump Sensor?

My local Bosch dealer wants £92.76 for the aux. pump....perhaps I shouldn't have mentioned it was for an Audi quattro!

Hi there

Not sure what the Audi PN is by I sourced my replacement directly from a Bosch (washing machine!!) agent. The Bosch pump was about 40% cheaper than the OEM. The Bosch PN for the pump is: 0-392-020-054 and it is identical to the Audi verison even down to the electrical plug.

For those that haven't seen it before. Must make a sticky

Than'x

Hi guys.
Just changed the little switch and the mfts on the water rail. Refilled the coolant as I took the rad out.
Okay start car wait to get hot and now the fan foes not even come on at all. Suggestions please. Checked all the fuses in the engine bay and all okay. Where to go next

Cheers

Fan "thermostat"/thermal switch not connected? Dunno if it's on radiator as it's in the larger body (UrS)

Hi there, I need some help, I can´t stop afterrun system.

I replace the sender and the 214 relay. All the fuses tested and ok in the fuse box.

The only way to stop it, is removing one of the 214 relay´s.

My car is an 1994 coupe ABY engine.

Many thanks
Fernando
