Hey guys I have a question. I have a coolent leak on my 01 S4. The problem is I cant freaking find it. It started out small but now it is really bad. Was wondering if u guys have any ideas where it could be. Im use to the the little 1.8t motors. But now I have this big guy under the hood and I can't find ****. Please help thanks.

 

check the axillary water pump under the intake manifold.

 

^^^^
this first.

are you getting a puddle on the ground or is your coolant just "disappearing"? It will help to figure out what might be leaking if you can narrow down whereabouts the leak is coming from.

 

Yeah I am geting a puddle under it

 

Back or front part of the motor where you are finding the puddle

 

The back I think. When I am under the car it is dripping in the back

 

refer back to post #2 in this thread

 

Ok thanks alot guys

 

Hey what do I need to do in order to replace the seal and what other gaskets will have to be replaced thanks.

 

you will need: intake manifold gaskets, aux. water pump, and throttle body gaskets. some people do this with out removing the throttle body. you will also need new hose clamps if you have the stock audi ones(one time use). you might also want to replace the two hoses that connect to the aux. pump. the are usually pretty beat up.
