First thing, did your mechanic pressure test your cooling system ? If not, request it.
If you are having to add a half gallon of coolant after a trip then you have a leak. A pressure test can help determine where the leak is coming from. The most common places for a leak is around the head gasket and around the water pump or through the water pump seep hole. Also, another suggestion would be to check your oil. If it looks milky, you have an internal coolant leak. If you have an internal coolant leak, get it fixed ASAP before serious engine damage occurs. Also, white smoke & a sweet smell are a good indication you have a coolant leak. On another note, your mechanic is wrong. Your thermostat is not causing the coolant loss.

Sounds like a plugged radiator. Same thing happened to me last year in my 1994 cavalier.

I had the same issue with a 2000 Cavailier. Mount a small plastic container and run the overflow hose into it. If coolant is coming out of the hose before buying another radiator cap do a compression test. If all cylinders are not up to pressure it could be the head gasket. Unfortuntely that is what was causing my coolant loss

ive recently had my thermostat replaced and my radiator flushed, i have a 2001 cavalier, instead of dex cool they put in the green type of coolant after the flush, but instead of my tempurature staying at 195 (exactly half), it goes up to 3/4 about 230 degrees, is this because of the different coolant (doubtful), the aftermarket thermstat, or the summer heat, it never done this in all these years since ive had the car i am the only owner..a mechanic said it WAS NOT a head gasket problem, please help
#10 of 48 Where is my coolant going?

My 2000 cavalier is loosing some serious coolant. There is no sign of external leakage and I've checked the oil and it's normal. There isn't any smoke either. Where is it going. I'm also loosing power and it's getting hard to start. The heater blows hot on and off, the thermostat has been replaced and the temp. gauge is on red and fluctuates. Please give me a clue!

Disconnect the radiator hoses, run water through the hoses and ensure no blockagein radiator or hoses. If blocked flush or remove and boil. Take the overflow hose from plastic resivoir & duct tape a soda bottle to it and wedge in engine compartment. If soda bottle fills up after driving car after enssuring radiator is not blocked run compression test. Most likely head gasket.
#12 of 48 Same issue, but its the water pump

Mine has been loosing coolant too. I suspected the head gasket, because my oil was smoking when I removed the cap, but it was still the same color. Also I couldn't smell any coolant burning in my oil. There wasn't any leaks on the ground, but I went and had it pressure tested, and it turns out that it was my water pump that has a small leak on it. I would have it pressure tested before you throw away tons of money to get a new head gasket, because that may not be what is wrong.

It sounds like you may have air trapped in the cooling system. The Cavalier has a bleed screw located on the high part of the metal coolant pipe in the front of the engine.
From: 2carpros.com forum...
"Always bleed air from cooling system after replacing coolant. Set heater for maximum heat. Remove radiator cap. Loosen drain plug and remove drain bolt (if equipped) from engine block. Drain coolant reservoir. Fill coolant reservoir to MAX mark with 50/50 water-coolant mixture. Loosen bleed bolt and fill radiator up to base of filler neck. Close bleed bolt when coolant flows out without bubbles. Tighten bleed bolt. With radiator cap removed, start and operate engine to normal operating temperature. Add coolant if necessary and check for leaks "

How can you test a relay so you know if it is bad or not?

My low coolant light has came on too with my 2000 cavalier. I keep on putting in anti-freeze, and have recently put it in 3 times within the past month and a half. I checked my oil and nothing is wrong with my oil, and my engine seems to be running fine; its not over heating on bit. What possibly could be wrong with it? Its leaking somewhere, but I'm not sure
