Question about 2003 Pontiac Grand Am
It is probably the problem. To make shure that need to change the gaskets, one of the symptoms use to be thet the temp rises when you are running at speed 50+ average, where is supposed that the car gets a lot of air due by the speed and nobody thinks that will be overheated.

Hi Melody- it feels like you could be right. it feels like your car was well worn when you got it. common causes of overheating are coolant too low, which is what i suspect was the case when you first got it. a stuck closed thermostat not allowing coolant to circulate. i assume you have an electric cooling fan- check to see if your fan motor is fried. you could also have large air pockets inside your cooling system which can give false coolant level. when you pour coolant into your radiator rather than your overflow tank, you introduce air into the cooling system that has to be purged by allowing the bubbles to work their way out through your radiator by squeezing your coolant hose you can assist the escape of these air pockets (with engine running) evidence of a cracked head can be presence of coolant in your engine oil-pull your oil dipstick and look. you say no evidence of coolant leakage, however, look underneath your car and check to see if there is coolant splatter surrounding the underside. it maybe that your car is maintaining enough pressure to run but when engine temps reach a point to where the radiator fan should kick on, and/or the thermostat should open to allow coolant flow and these things dont happen-the result is what you describe with no power and overheating that will eventually overstress your head(s) warped heads can cause the symptoms you describe. you can perform a compression test to help pinpoint a blown cyl. an idea for fixing your car for cheap would be to take it to your local high school auto shop. the only way kids learn the trade is by subject cars. ill bet you can even arrange them to pick it up. the will fix your car for cost. you would only need to supply whatever parts are needed to make the repair. its a win-win situation because they get to learn by fixing your car and you get to use your car for doing mommy things without fear of labor fees. which are around $120/hr. I hope i have helped you with your car good luck!

If your timing is off you will have no power.check and make sure all timing mark's are correct.Some engine's are contact motor's,which mean's if your timing is off you could cause damage to valve's or piston's.Also you should do a compression test to be sure each cylinder has adequite pressure.Hope this help's.

Most often on those the motors are shot. as soon as they are activated they overheat and slow down or stop. Only way I know of to repair is to replace them. You will need a manual to do this or do them one at a time so you can check how it goes back together by looking at other one. Motors are riveted in and need to be drilled to remove...use small bolts to re-attach.
I've seen motors online for about $30-40 each.
