I'm in the process of replacing the water pump on my 95 LT1. The book says to open the bleed screws on the throttle body and bypass hose before refilling the the system. I have not located the screws they are talking about. Can anyone tell me the location of the TB screws and the bypass screw? So far, the only screw I've seen is connected to the top cover that fits over the thermostat.
There should be one under the throttle body where the hose goes into to it from the cooling system. I have tried the books method of bleeding and found that the system wil still have air in it.
I disconnec the hose that goes from the coolant resevour above the ac evaporator to the top part of the radiator on the passenger side from the radiator as I fill the system. Once coolant drains from this opening. I close it and then follow the bleed procedure using the bleeding screws.
