1994 Grand Am running hot
Need some help on this one. I replaced a head gasket on a 94 Grand Am with a 2.3 Quad 4 in it. I replaced the water pump and thermostat. It now gets hot (240 degrees in climbs) 15 or 20 minutes after start up. Don't know if it was getting hot before I replaced the hed gasket because I did not drive it. I feel of the hose entering the radiator and no flow. I replace the thermostat with another new one and same thing. I am at wits ends with this thing. Does anyone have any suggestions. I will be going back down to Albany this weekend to work on it again. Thanks in advance for any help... :? :?

I would say try it without the thermostat in. It could be the thermostat you got is bad.

Is it possible the bottom rad hose is soft and collapsing shut? See if it has wire retainer inside of it.
Also, after changing the pump and thermostat, did you "burp" the system, get all the air out of it...? This is a common problem in circle track modifieds when radiator cap is lower than the thermostat housing... air trapped in the system blocking flow. Jim |
hey chris, i have a 2000 grand am and problems never stop. looking
at your post and trying to come up with something, now just checking. did you boil the thermostat and make sure it opened? if that is fine, did you run the car w/o the stat to see if the pump was working, i replaced a pump from autozone 3 times and ended up with one from NAPA, learned my lesson. and if not, there must be something blocking in the hose, i'd like to go help just to get the answer, good luck bud, and post your findings :wink: |
its air locked, this engine is a bi**h to bleed. did you use a cooling system filler to fill the system? or (your not going to want to here this) did you check the head for warpage? if you didn't there is a very good chance that it is, its air locking on exaust getting into the system because head gasket did not seal. presure check it.
