D5254T (to 2002, Audi) - Engine Coolant drain tap?

alangorham · Nov 8th, 2008, 15:14

Does anyone know where this tap is?
I want to replace the coolant on my 850 TDi but the only coolant drain I can find is on the right hand side of the underside of the radiator.

I am sure that if I can't locate and open the drain tap on the engine, then I will get airlocks when I refill the coolant.

The owners manual is very vague. It mentions that the tap is on the front of the engine block?

Thanks

Alan

It's on the front of the engine (front side that is) around half-way along IIRC. VERY hard to see and get to, it's underneath the manifold but you will need to drain from it or you won't drain sufficient a/freeze. You're looking for a downward pointing drain tap which is operated with an open-ended, possibly ring spanner. Regards.
