Hey Guys, brand new member here. Have been hanging around and reading for a while though. Alot of good info and knowledge to be had from you.
Anyway, a little background before my question. I've got a 98 Suburban, 5.7 Vortec, 160k, 2WD, Auto.
A little while back I had to replace the intake gasket. And about a week later, started to see coolant again. Thought it was the gasket again, but lo and behold, it's coming from somewhere else. And it's the "somewhere else" that I need help with.
It seems to be leaking from a plastic housing valve that has a small vacuum operated diaphragm attached to it. In addition, there are four 1" (ish) coolant hoses coming out of the plastic housing. Since it's dark here, the only 1 that I can positively tell where it's coming from is the top of the water pump. The leak seems to be coming from the valve body itself or possibly one of the connection points for the hoses. My best guess is it has got something to do with the heater system.
It is located in between and about 6" below the coolant resevoir and the intake filter housing. Some of you probably already know what I'm talking about, but i'm at a loss on this one. I have also attached a few pics to kind of clarify my rambling.
Thanks for any and all assistance! Greg
