Most likely there's air in the cooling system that needs to be bled out. The other possibility is a blown head gasket. The 3400s are notorious for blowing head gaskets. Pressure test the cooling system. Also pull the oil dipstick and look for white milky "goop" on the dipstick. That's a sure sign of a blown head gasket. HTH. -Jim

Someone told me since my air dame is missing that could cause my car to run hot also. Ive bleed the system theres no water in my oil.

That's definitely a possibly. The air dam increases the airflow through the radiator while driving. Has it started heating up when you lost the air dam? HTH. -Jim

I have had it flushed and new thermostat. It starts running hot with in 10 minutes of me driving it but when it does I pull over and open the bleeder value and the temp. drops then I can drive it for a while but when I cut it off I have to add more water to it

Before spending the money on the air dam refer to my first post. Rule out a blown head gasket before spending any money needlessly. How many miles are on the car? HTH. -Jim

Not sure the motor has been switched to a 3400

I see. They usually failed between 90,000 and 120,000 miles. That's probably why the motor was changed. The original engine probably blew a head gasket. - Jim

I have a question I replaced my fans on my alero and they are going slow and I was wondering why are they going so slow?
