If your coolant level is dropping, I would suggest that you take a good look at the water pump. That is a very common coolant leakage probelm area on your vehicle. I change 2-3 a week.
Hope this helps.

First thing I guess I better ask is how much water did you add,vs antifreeze? If your adding to coolant return bottle, and it's already used the antifreeze, and bottle is full of straight water, in a cold area, bottle could freeze. If it's already entered in to rad & cooling system, then it's probably mixed in already & a simple antifreeze tester ($5-$10) from autoparts store, or hardware store will give you your mixture strength. Now, you may end up changing your thermostat, but lets check a few things out first. Do this with engine cool or cold. Take rad cap off, observe level in rad and add coolant at least 50/50 for now, to top it up about an inch or 2 from top of rad, if necessary. Now, Start car, turn heater on (not defrost) and let engine run while you observe level in rad & temperature gauge from time to time. If level goes down, add as needed. As engine warms up to normal operating temperature, observe rad fan and make sure it comes on, before engine runs in to hot zone on gauge. Let it run until rad fan comes on & off 2 or 3 times, while you keep an eye on coolant level & temp gauge. After 3rd time fan on & off, coolant level up to inch or so from top, put your rad cap back on, and now fill your return bottle to proper level with coolant mix. Try that & see what happens & if it overheats, get back to us, if not "happy motoring", and get that coolant strength tested, as well as keep an eye on return bottle level. If it keeps going down and you have to add frequently, then you need to have it tested for a leak in the system.

If you had to add that much coolant, you have a serious leak somewhere! Find and fix leak! Probably got air in cooling system. Sensors only read when submurged in fluid.If antifreeze/coolant did NOT say 50/50% and/or ready to add and/or premix then yes you can dilute it up to 50% with clean water. Hope this helps! Rate me please.

If the unit overheated and there was no coolant flowing into the reserve tank, then there is two possible issues that must be addressed immediately. Either (1) There was not enough coolant in the system. This is because when the coolant heats up it expands and will go to the reserve tank. The fact that there was going to the tank indicates that the system is less than full, or (2) The radiator pressure cap is defective.

I would flush the cooling system, clean the reserve tank, replace the radiator cap, and refill the system and retest.

Either get a coolant pressure tester, or take it to a shop for a cold pressure test. What you may be experiencing is a leak when the system is hot, and the liquid doesn't

stay liquid, but steams off as a gaseous vapor. So, you can look for the remains of what used to be liquid, a crusty discolored buildup near the leak, or pressurize

the system when it is cold and look for signs of a leak, in other words, a liquid.

My temp guage just shot up to past the H, my coolant is empty. Do I just wait for car to cool down and add water to radiator or add coolant at any time, or both?


DON'T PUT WATER IN IT HOT!!! You need to wait a few hours to add water water, the engine should be cool to the touch. Or if you can heat several gallons of water to around 170 degrees or so you could add to the system hot. This is also dangerous since that hot of water can burn you. Adding cold water to hot metal you run the risk of cracking your engine, or at least your radiator. Best of luck hope this helps.

It is much more likely you are low on coolant or you have an air bubble trapped in the cooling system. You should bleed the cooling system to get any trapped air out and make sure it is full of coolant.

I think your buick has a pressure coolant system so you may have air in the system and need too bleed it and for the light coming on while on the highway most likely low coolant when your driving the higher rpm the more coolant is drawn into the motor and triggering the light from coolant reservoir running low on coolant

1997 2.4L Chevy Cavalier LS; Low Coolant Indicator and Temp Gauge


take the cap off of the radiator (whil engine is cold) start and run the vehicle. keep runnig 30mins after the vehicle is hot keeping notice of the rad fluid level.
keeping the cap off will prevent the pressure build up that woiuld keep the air in the system, keep adding water or antifreeze as the level goes down. this may take an hour or so.
also with the cap off, you will be able to see if your water pump is operating correctly. you will visibly be able to see movement in the rad when the pum is engaged.

Still losing coolant


Hi, Sounds like the water pump is not circulating the water, as soon as the engine heats what water is in it, it will boil. Since you are brave enough to open the radiator when it is hot ( Bad Idea ! ) open it when it is cold, start the car and watch to see if the coolant circulates. You may have to wait unit the thermostat opens and if the water pump is bad when the thermostat opens it may spray hot coolant and steam instead of circulating what is in the radiator so don't be in the way. Not the best way to test this but works if you don't have diagnostic tools. Good Luck! By the way, coolant means antifreeze mixture which if it gets too thin lowers the boiling point significantly.
