I just bought a 95 pontiac grand am that had the same problem. I immediately suspected the cooling fan so I went to remove it and realized that the fan blade wasn't even attached to the fan motor...you may want to take a continuity test through the fan or a voltage reading from the plug once your temp gauge gets half ways up. otherwise, check the fan relay

I need to remove the fan from my 95 pontiac grand am and the repair manual says to remove the front wheel (but it doesn't say which one. lol) , then remove the bolt from the lower torque axis mount (but doesn't show me any pictures or tell me where it is), then I'm supposed to be able to rock my entire engine backwards so I can remove the fan. does anybody know where to find this lower torque axis mount?...pictures would help

I have pretty much determined that I have a blown head gasket. my engine is a quad 4 and I found out that the fan for the car was missing the nut that holds the fan blade to the fan motor. I have started ripping apart my engine to remove the head and have it re-surfaced and replace the gasket. I am currently stuck on removing the rocker arm covers. it looks lik,e the may be bolted to the timing chain housing and if this is the case, I will have to support the engine with a jack, remove the upper motor mount so I can remove the timing chain cover...boy is that gonna be fun. but that is not my main concern right now. I am borrowing my girlfriends car which is a 93 Grand Am. Her brothers replaced the harmonic balancer, and the master brake cylinder. But when they put the wheels back on, now the steering wheel shakes when you drive like something is unbalanced on one of the wheels. she said that before they did this, the wheels only had 3 lug nuts on them so I don't know what's going on, but I'm gonna try and fix it tomorrow. I could use some advice on what could cause this.

Hi every1..im new to this site and was wondering if you could help me out. I have a 99 grand am gt with the 3400 series engine that has overheated on me more than once since i got it. There are no visable leaks in the coolant system but the coolant keeps going dry. my son suggested that i replace the thermostat. Would the thermostat be helpfull or would it be sumthing more serious? Oh and when i bought the car, the car lot i bought it from had the headgaskets replaced and the oil looks perfectly fine.

If there's no apparent leaks either on to the ground or into the oil then the only place the coolant can be going is into the cylinders or cylinder and out the tailpipe. Any competent shop can do a pressure check of the cooling system and diagnose the problem. My gut feeling is either a bad gasket somewhere (head or intake manifold) or worse a crack in the engine somewhere.

GA overheating and coolant leaking

My 93 grand am is leaking coolant from a hose under the car. I took it to a shop and they replaced the water pump and the thermostat, and then did a pressure check to make sure that the block wasn't cracked. $350.00 later the car is still leaking coolant out of the same hose. Anybody know what I'm talking about, or has anyone experienced the same thing?

If you have a confirmed leaking hose, then why was all this other work done? I mean, why wasn't the leaking hose replaced in lieu of all this other work? Also, what engine are you talking about, the V6 or the Quad 4?
