2004 grand am is overheating and i coolant going down

pull the oil fill cap and look at the bottom and tell us what you see , also what does the exhaust look like ?

Make sure your cooling fan on the radiator is working then make sure your radiator cap is tight ... if it's loose the radiator won't have the pressure to keep the coolant from boiling

There is no radiator cao in this car and the coolant cap is tight fitted in there... ???

The cap is probably buried and coolant goes in the reservoir but yeah , see if the rad. fans are clicking on when it gets too hot , that should have been # 1 ,(oops)

I checked the fans and took the temp over 100°C but fans doesn't start on thier own...i need to turn on the AC first... then the fans start.. Don't know why is this happening

The relay/fuses are inside that black fuse box just in back of the battery ... You can use the AC to keep both fans running until you locate the problem

I would think normal operating temp. would be about halfway on the temp. gauge , give or take . So 100 c is above what you think is normal , whats that 212 f , yeah thats a little high I guess . Usually it's the temp. sensor , If I knew how to test it I would tell you , or you can replace it .Fans coming on when A/C/ is on is normal and the gauge drops when they do ? what does it look like under the oil fill cap ? what does the exhaust look like?

A 7 lb radiator cap will not open until about 231F and a 15 lb cap is good for about 250F before you boil over

I'm not loosing coolant but my 2004 grands am gt s fans only kick in when the air is on. They don't kick in themselves. Idk what to do. I just changed an alternator, I'm a girl that's going off memory of my father. Can anyone help me? Is it a fuse?

I’m having the same problem There is a bleed off valve just above your water pump you may have air in the coolant lines I just changed my water pump and thermostat And it’s still over heating fans kick on but the built up air in the lines keeps water from circulating properly And I am also losing coolant I think I may have a crack in my radiator hose that goes into the intake

These engines like to leak coolant through the lower manifold gaskets into the oil. If you pull the drain plug, the very first thing to come out would be water if this is your issue. I have never seen a GM 3.1, 3.4, or 3.8 that did not eventually need an intake set done on it. They are reliable but that is their weak spot. Head gasket problems are rare, but intake will produce the same symptoms.

Whenever I have a coolant overheat or coolant loss issue I use a radiator pressure tester kit to see if it leaks somewhere. If no outside leaks appear in 30 minutes at 15 PSI on the tester but the tester needs to be pumped again (pressure loss), then drain the oil and let it sit overnight. Test it again when the oil is done dripping. If it starts leaking water out the engine oil drain plug within 30 minutes then intake has to be done. You can borrow the kit from Autozone or most other parts houses.
