OK its a 99 gt, i can see coolant pouring from right behind the altenator... Took the alt off and see no cracks or anything..... any ideas on what it may be??? ....... thanks

 

gotta find where the leak is coming from. You should be able to start taking off pieces, and maybe get one of those flexible, telescopic little mirros to help you see behind something to locate the leak. Probably a bad intake manifold gasket.

 

The 99's have the plastis intake crossover peice and thats probably what broke on you.

 

99.9% chance your intake cracked...buy a new one like 180 dollars..call it a day...

 

+1.

 

Pretty much sums up the solution.

 

ts the plastic intake, i had the same thing happen to me and I couldn't find the pinhole leak. I beleive it is a recall item, check your dealership. Mine was, didn'y pay a dime.
