On my 97' A4 1.8TQ I replaced the gasket on the intake manifold this evening and I thought everything was fine.

Well you know the connection for the coolant line that goes over top of the intake manifold and connects to a fitting on the back side of the engine? It has some sort of slip joint with two bolts holding together the slip joint.

For some reason now when I put it back together it is leaking from that joint and it won't hold coolant. Was there suppose to be some kind of rubber o-ring maybe that fell off?

Any one know what I'm talking about?

Thanks,
Chris

If so, yes, there's an O-ring in there that seals it against the head. It costs like a buck or two at the stealer and takes 5 minutes to change.

It looks like a housing with a sensor, but the connection point is not on the head. It is where the upper coolant pipe fits into the housing. It is a male/female slip fitting and has a little bit of slop in it so i think it needs an o-ring, which some how must of disappeared when i had the intake manifold off.

Yes, there's an o-ring there too
