Re: What water coolant source should i use for ball bearing turbo?
Actually I think its the other way. Unless the 4.3 ( which to the best of my knowledge is the same as a small block chevy) is reversed cooled, it flows into the block and out of the intake manifold. This is why the heater core gets its coolant from the top of the manifold, its at its hottest. I never had a stock turbo on my truck but if the lines were ran that way does anyone know how to get cooled water before it goes to the motor to the turbo? I was told tapping the side of the water pump was one way and the block drain plug hole was another. Anyone ever tried either of those?
