Hi all this is probably addressed somewhere but I haven't found it. Trying to bleed the cooling system on my 1994 LT1, but either I am not opening the screws far enough or not leaving them open long enough. About how many turns should you open them and about how long does it take before coolant starts to come out? Does it usually come out of the throttle body bleeder or the thermostat bleeder first? Because this may affect your answer I drained the radiator and got the knock sensor out on the passenger side but I couldn't get the one on the drivers side out. In total I drained a little more than 2 gallons of coolant.
Thanks.
Thanks.
