pop the radiater cap off and let the van engine run for 30 minutes. this will burp out any air in the cooling system and your engine will not overheat then. afterwards, fill the radiater back up as needed.
by either using a pressurized tool for filling it or along the top of the intake there is a coolant line that has a *bleed screw* that can be opened while filling it till coolant comes out of the hole then close it up
i need a pictrure of the cooling system diagram for 1995 Chevy suburban
R134a
yes
I've got a better question, why is this question in the Chevy venture forum ?
Engine cooling system is not a closed system you can't remove the air.
i can,t find the acumalator on my 2002 Chevrolet venture
Engine cooling system is not a closed system you can't remove the air.
When the engine is cold, remove the radiator cap, top off with a 50/50 mix, and start the engine. This will allow air to escape from the radiator. It may also have bleeder valves located high on the cooling system. The location will be listed in your owner's manual.
Use a flared end wrench or crows foot to loosen.
There is a screw right on top of the line about in the center of the engine (maybe a bit to the right as you are looking at it). Loosen it and let the air out, when fluid starts to come out, tighten it back.
You will need to remove the anti-freeze from your 1997 Chevrolet Venture cooling system. Remove the water lines from the heater core. Remove the heater core retaining bolts. Reverse the process to install the new heater core.
