chicago,
ive got an anti-freeze leak on the drivers side rear side just at or above the oil filter,but its been raised up on a lift and the left wheel well has been removed and 3 trained mechanics can't find the leak ,its at the chevy dealer now ,could it be the eng oil cooler [isn't it in that spot?]
 
Oil cooler is right there, all the coolant flow from the water pump runs directly through it before entering the engine. Freeze plug and head gasket are also other possibilities.
