thanks Guys, it was the water pump. Once I pulled it out, the upper weeping hole was the one that was leaking and sending water out to the back and sides. I replaced the water pump and hoses etc., and started it up. Thank Goodness, no more leaks. Took it for test drive and back, everything is back to normal.
The metal fan is very heavy. Why? After installing the water pump, I fired it up with the fan and the truck ran very smooth and quite.
GLC: The lower and upper intake gasket was replaced in 2008 on this truck before I bought it. the truck was running fine, the original problem was the coolant leak.
Thanks for the input.
