The car has never overheated.
Heat works fine @ low speeds(0-40), but @ high speeds(40-70) the temp gage Drops. and heat is lost. You can actually watch the tem gage drop.
During the Summer it's not a problem, I maintains a constant temp. but during the winter is when the car has problems.
Before anyone says replace the Thermostat That was the first thing done.
Everyone I have asked looks at me like im an idiot. I have no clue of what to start with to fix the problem

The behavior you describe indicates that the radiator capacity for cooling is too great for the need and this causes the temperature to drop. The thermostat is designed to open and close as heat demand dictates. If the thermostat is open too far, you will see exactly what you describe when it is cold out like in winter. In summer, when the ambient temperature is higher, you will not.
The themostat is either improperly installed or blocked in the open postion. Although you replaced it, you may need to do that again. You can also test the thermostat if you have a hot plate, a large pan of water, and a thermometer. As you heat the water with the thermostat in it, you will see the unit open; measure the temp where it opens as it may be too low.

I know you said the you already have replaced the thermostat but just because you put a new one in it doesn't mean that it is good after all it is man made, if it isn't the thermistor then you have something blocking it open or else it is installed wrong., If you check all of that and it still Dons';t work then try getting a lower therm and try that.

first of all, i've got faith that your motor would not have a timing belt, it has a timing chain. in assessment to a belt, they grow to be badly stretched and could no longer destroy. Secondly, the blow via ought to intend as low as a defective PCV valve or as important as undesirable piston rings. if your motor is hitting the firewall, it is by using a foul setting up and could be checked for risk-free practices motives as nicely because of the fact the knocking nuisance. finally, you will locate many areas on your Cavalier. i got here across some on eBay, Summit Racing equipment or purely Google: "Cavalier overall performance areas". I even have even got here across a turbocharger for mine which will make it able to working 12's interior the quarter. via the way, I own a 2004 Chevy Cavalier and the only issues replaced on it are the headlights, brakes, tires and oil. It has over a hundred and twenty.000 miles on it and nonetheless runs like a raped ape! they seem to be a great automobile. maximum folk forget the crap out of them and nonetheless anticipate them to run like a clean automobile.

You might want to check your radiator cap... but if anything No offense it is a Cavalier. In my opinion sell it and buy an import like Honda, Toyota since they are more dependable vehicles.
