I have a question concerning refilling the cooling system for my 1992 C4.
I purchased a Hayes Repair Manual and it states to"Open the bleed screws on the throttle body and bypass hose for 1992 and later models"before filling the radiator surge tank. I must be blind I dont see these bleed screws or i dont know what to look for. If anyone could point me in the right direction it would be much appreciated.
The screws are brass and slotted . Before you open them make sure to stuff some rags under them .You do not want coolant to get down to the Opti-spark. :seeya :flag
The bleed screws are brass. One is located on the passenger side near the top portion of the hose that goes to the lower radiator opening. The other is on the drivers side located were the small outlet pipe goes into the throttle body.
