I have a 2001 Duramax with 147,000 Miles on it. Over the winter I noticed a little puddle of coolant under the truck. It appeared to be coming out of the back of the engine somewhere. This spring I took it in for a coolant flush and to have the dealer locate the leak. They called me immediately and said its coming out of a seal in the back of the engine. To fix it, they would have to pull the motor. Anyone else have this problem?

Quick fix?

Let me know

on the top passanger sid eof the engine there is a plate with a gasket that i had a small weep.... ill see if i can find the parts diagram, dealer said to pull motor but i got a gm tech friend to take it on, he removed the turbo and beat up his knuckles pretty good.... tough job...

My heater hose was leaking intermittently where it goes into the firewall.It has the spring clamp on the hose,not a regular wormgear clamp.It dripped down the right side of the engine and appeared to be coming from a multitude of places before I finally traced it to the heater hose.I just squeezed the clamp with pliers and rotated the hose back and forth and it has not been a problem since.
