Rear head coolant leak

[taz069]

Morning all!! What is the name of the coolant tube that enters the rear of the head on the driver side. I have a slow coolant leak and for the life of me i cannot find the proper diagram. It is looking like it is the o-ring because the hose is not leaking. I have been to ecklers, and autohaus, and googled it also. And cannot find the proper seal. Maybe some one has a better clue than me. Thanks.

Hate to sound like an ass but for the love of God people please post year / engine!

There's a plastic pipe at the firewall on all 202's for the heater core, they are cheap but a little pita to replace. They crack and crumble.

I'm assuming you are talking about the metal flange fitting that bolts to the back of the cylinder head? Then yea there's an O-ring there. If you post a pic of the leak I can probably get that O-ring for you.

Sorry remo. It is a 1996 c280 with the m104 inline 6. The tube enters the block at the back side of the intake where it mates to the block. The tube has a small o-ring.
