It appears to be coming from the lower right bolt on the front cover plate. (while looking aft) That's the best I can trace it. The bolt is not loose and the only work I've had done in the area is the alternator bracket SB. It flows down then drips off the oil pan. The leak stops once the engine reaches operating temp. I'm at a loss. Could it be the overflow, the water pump??? Please help.

 

maybe i am thinking of the wrong place but check the coolant hoses on the bottom of the throttle body.

 

It is at the bottom of the engine near the oil pan, right side, front of engine. Coolant is actually running down the block. Car is stock.

 

Headgasket? Waterpump?

 

That is where the thermostat is. Check the hose there. Mine never leaked, but the GM factory clamps are worthless in my experience....

 

i've got the same thing. mine (the best that i can trace it) is coming from the water pump. i could be wrong, though.
