94 V6

I don't know how to. Looks like air could get trapped in the top of the thermostat housing. NO BLEEDER ON THE HOUSING.

Pulling the hose loose looks like it could be messy.

My Chilton's manual indicates that the bleed valve is near the EGR valve outlet pipe ("place rag under bleed valve to avoid getting coolant on the EGR valve outlet pipe"). I have never looked at a V6 that close, but that might point you to the correct area.

No bleeders in this area by the EGR outlet tube.



Just the valve cover & plug wires. The cap at the bottom is for the A/C.

The 3800II has a bleed valve near the EGR system (driver's side). The 3.4L doesn't seem to have one according to the Haynes, which is the only manual I've got with the 3.4L Camaro/Firebird engine.

Agreed, NO BLEEDERS.

Still to be answered:

How is the system bled?

Bleeding the system seems to be a problem pimarily with the "reverse flow" cooling system on the LT1 engine. I've never run into a conventional flow system that had a bleeder. The conventional system flows from low in the block, and rises to the heads. Air/bubbles will rise to the top and flow out the return line to the radiator. With reverse flow, the coolant flows to the heads first, then drops down through the block, leaving bubbles and air pockets at the top of the system.

leave the cap off the radiator and fill it to just below the next and start the car up, when it warms up the thermostat will open and suck the coolant in, then just keep adding till the radiator is full then top off the overflow tank to the hot mark
