#417 of 2171 Overheated Cavalier (please help)
Feb 01, 2001 (7:56 am)
About a week ago the A/I started to act up on me ( I could hear the fan or compressor star going on and off and could hear a loud click as it went on and off). Around the same time the low coolant light started to go red (This would happen if I made a sharp turn and I thought it was mostly because the turn was moving the coolant around to one side)
Anyway a couple of days ago I noticed the temperature dial going almost to the red. My commute is against tragic so I am almost never get stuck. But the last couple of days I was sent to another location where I was stuck in traffic, and seeing the dial on the red was scary. I stopped at an auto parts and bought some of the orange coolant and filled it up with the 50/50 mixture. This did not fix the problem as my dial went to the red again yesterday and today while going to lunch the car not only over heated but the coolant overflowed after coming back.
What could this be?

Check your thermostat or water pump. Everyone that I know has had problems with water pumps in their Cavalier, so that may be it. Good news is that neither one of these parts is that expensive.
#419 of 2171 weird noise?
Feb 01, 2001 (5:26 pm)
I just got a 2000 4dr 4speed automatic cavalier.I noticed whenever I slow down to come to a stop I hear a noise that sounds like low.. low.. low low low. Please don't laugh It's totally anoying. We also just bought a 2001 that doesn't do this. I had it back to the dealer they checked the brakes and they were fine. I came from A much bigger car, is this sound just normal for cavaliers? Please help.

Strange noise. Is it very loud? We have a 99 and it does not do that.

It is loud enough for my son to ask me what that noise is from the back seat.

Get it looked at and if your dealer can't find the problem, bring it to another. Brakes in small cars do make more noise than in mid-full size cars, but that is abnormal.
#423 of 2171 Overheating Part II
Feb 02, 2001 (7:58 am)
I took the car to the mechanic. He told me the following were bad: The fan motor, the termostat, and the seals in the bottom of the radiator went bad because of the heat. Total damage to replace those 3 items and an oil/filter change was $245.
I told him to go ahead. Do you guys think it was a fair price?

Does it happen *only* while braking, like a low scuffing noise? New or re-machined rotors have a slightly abrasive surface. This is normal. Smaller cars tend to have less sound-insulation, so you'll hear more.
Does the car seem to stumble a little or even jack-rabbit as you're slowing down (like leaving a manual tranny in top gear)? That would be a sticking TCC solenoid on the tranny.
High-speed rumbling is from out-of-balance wheels but goes away when slowing down (so unlikely).

A dead fan or bad thermostat can cause damage, yes. If $245 fixes everything, consider yourself lucky. Usually an overheated car will have some engine warping, requiring more $$$.
The fan is only needed when going slow or when stopped. At good speed, the fan is normally off because the air rush is plenty to cool the radiator. If the fan died, then you'd only overheat when going slow or stopped.
A stuck thermostat will overheat you no matter what speed you're at. The thing about thermostats is that they're one of the cheapest part on your car. Usually when the coolant hoses are changed every five years, the thermostat is changed too.
My '89 Cavalier overheated when the heater core's plastic pipes broke. This killed the water pump and warped the head block. I knew the head was warped because the water jackets no longer mated and coolant oozed out from the head gasket as well as got into the cylinders -- got white smoke out of the exhaust. I learned that day that coolant in the cylinders will make your engine run very poorly.
Replaced the water pump and remachined the head block. Amazingly, the engine runs just fine (230k miles and rustily going).
Final note when a car is overheating -- if you're losing coolant too, you have a leak in the system, meaning the car's normal method of pulling needed coolant from the overflow reservoir won't work well if at all. Make sure the car is completely cool then add directly into the radiator (if you have a cap -- the newer cars don't).
#426 of 2171 Headgasket warranty limits?
Feb 03, 2001 (8:42 pm)
Found some OLD posts about headgaskets and 100K warranty. What warranty is this? When my 92 Cav had problem last spring at 80k or so, all info I found on net said it was 7 years time also so I was SOL. Did I miss something? TIA!
