1998 Pontiac Sunfire..... HELP!
 

Ok, my dad's friends' daughter has a '98 Sunfire with the 2200 4 cyl. She said it runs a little hot, so she put GREEN antifreeze in it instead of the Dexcool, so they are mixed :roll: .
Now the problem is, is that the car warms up fine, fans work, doesn't overheat but has NO pressure in the cooling system whatsoever. I can open the tank cap after it ran for 25 minutes and didn't even make a slight psssh. The car has 164k on it and idles perfect, no coolant in the oil and vice versa. What can it be? It's very odd. We are draining the coolant out of it tomorrow and fully flushing the system.

Fully flush and replace the thermostat as well... Might be slightly stuck open, Might not be a good thing if it does get really hot( may not be open far enough )...

Another note for you... Make sure she does not let that engine get too hot... That head will not tollerate being overheated at all... I have seen too many 2200's with a warpped head... Usually seem to leak towards the transaxle side of the head..

A bit easier to fix than a Quad tho ;)
