Cooling System bleed

jmccloud · 10-10-03, 09:44 AM

I've located the bleed valve on the thermostat housing and the GM manual shows another just behind the housing and below the throttle body assembly -- but the second one isn't there!
Was this eliminated for a '95? Or am I just going blind?
Anyone know the location or whether it was un-necessary?
Thanks for inputs.

I have noticed the same thing & can't find a valve other than the one on the t-stat.
I guess the terminology they use can cause you to look for a valve that isn't there.

Thanks for the sanity check!

It appears that F-body LT1s have a second bleed valve located in a tee where the coolant from the throttle body connects to the heater return hose.
