I have a 97 yukon with the 5.7 vortec. Its been loosing antifreeze. Granted i just did the head gaskets maybe 10,000 miles ago. Today i brought it home and a puddle of antifreeze on under the truck by the rear of the motor on the passenger side. I can see it its all over the starter trans and oil pan. What would cause this? Freeze Plug. I am not to familar with the vortec motors. can someone help me please.. it snowed here now i dont have my 4x4 just 2 camaros lol..

Well, check to see if the heater hoses are in good shape.

also check the coolant nipple on the intake. could be leaking and letting the coolant run towards the back of the engine......... also check your heater hoses and back of the intake........

Jusst checked heater core hoses.. I can't see th other because it is dark now.. it is wet on the passenger side of the motor.. and it only leaks after the car is heated and cooled down

the cooland nipple is on the front passenger side of the intake usually the o rings rots away and it starts to leak

Check to see if you can borrow/rent a cooling system pressure tester. That should help narrow it down.
