Sounds like you have a slight bit of air still left in the system.There are 2 bleeders 1 on the t-stat housing and 1 over the water pump housing.Try bleeding again.

My grand am still overheats even after i changed the termostat and water pump plus, the fan only runs when the temp sensor is unplugged

I had the same problem with my 1999 grand am .I changed water pump, thermostat. I heard the Pontiac engines , 3.4 had overheating problems one is the intake gasket if your losing water but don't know were its going its leaking at the intake gasket and burning off or if you check the oil cap or the dip stick and theres a milky substance on them it would be your head gasket I had to change my head gasket and while I was there I changed the intake gasket too. I haven't had any problems sence I changed them hope this helps. Jack

99 pontiac montana overheaten already changed thermostat what is it?

you have a GM common problem and that is a bad intake manifold gasket. GM change the gaskets to plastic and they crank and leak causing over heating. here is a picture of one i took from a 2005 pon. bonneville with 74,000 miles on it2_12_2013_3_00_09_am.jpg

Leaking fluid from over flow hose

Could be a bad head gasket or intake manifold gasket, clogged radiator, or air trapped in the system.

I have a 2006 pontiac grand prix 3.8l my heat only blow cold aair I checked the thermostat and the heart inlet hose is hot but the outlet hose is luke war what could this be maybe clogged heater core.

Ok fellow 2006 Grand Prix owners!! By trial and error, I went through the process of elimination because my car would over heat and had no heat inside. After changing the thermostat, I had to replace the water pump. However, after you do this, you need to open the inlet hose bleeder and let the air out a few times. This solved my issue of overheating and I now have great heat!!!

I Have a 1997 Pontiac Grand Prix, For months now my temperature gauge has been running hot to nearly 260 degrees. The car has never officially overheated although the fans do kick in, In the last few...

What's chances that the temperature gauge or sender itself is wrong?
Is the heat exceptionally hot? What temperature is the heater dicharge when the gauge reads 260?
I think that the sender is not expensive, try that. An auto parts store could get you an inexpensive dial gauge that you might be able to install in place of the sender.

I need a diagram for the thermostat on the 2000 pontiac grand am 3400

The thermostat is located in the thermostat housing which is located on the intake manifold under the throttle body. If you have small hands, you can remove the air intake tube from the throttle body and the exhaust crossover heat shield. Once there out of the way, you can remove one of the bolt and losses the other to slide the thermostat housing off to replace the thermostat.

If you can not get to the bolts, then your going to have to remove the throttle body and don't forget the order the new throttle body gasket also. Not that the coolant temperature sensor is on the intake manifold in front of the thermostat housing, so take caution not to damage it when removing the housing.

Thank you for using fixya and keep us posted.

Car keeps over heating, radiator will only hold about a gallon of water, changed the intake manifold gasket, no water in oil, tempature keeps jumping around

your most likely problem is your thermostat, replace that and if is does not fix it, flush your radiator and take off all hoses and be sure they are clean of build up.

Over heating leak in water pulm gasket need to know where termo is

Thermostat is not the problem,replace the gasket on the intake,and plenum,if it has a plastic intake,replace it,you will find at the e g r port,it is distorted,and the new intake will have a stronger renforced intake,you can buy it at napa auto parts.

94 grand am over heats

it could be the cooling fan. Or it can also be the TCS temperature control sensor. when you have an opportunity have it scanned for a code at any autozone or other parts store. They do it for free at Autozone.
