Question about 1997 Chevrolet Cavalier

1 Answer

Only thing left that could cause overheating of my 97' Chevy Cavalier is the engine block restricting flow and boiling the coolant because i now have a new pump, thermostat(put heat to it and it works at proper temp) flushed the radiator and hoses checked everything else up to the block and all passageways are clear so the only thing left thats possible is the passageways through the engine itself. just not entirely sure how(apprears to have a fairly new head) and my dad bought the car in florida near the coast sadly, original dealer was in vero beach. and it belonged to a college student, and from the amount of corrosion on the pump it would seem that they poured some salt water in the resovour....

Do a combustion test at the radiator

I bet the head gasket is failing

    well i took 3 days and replaced the head gaskit and got everything buttoned up. BUT it all turned out to be a kinked coolent hose most likely, due to the heater core not working they took a small hose and bypassed it. BUT they put a straight one that had kinked so i took it up to carquest and got one that was curved in a almost U so now everything is working great :D

Car coolant boiling but not overheating what could be the issue? In a 2006 chevy impala

How hot does the engine get in degrees F? If it is boiling the coolant is overheating. Does the radiator fan work? Check the thermostat, check coolant flow through the radiator. Could be head gasket issue? Sometimes air in the system can cause problems? Just my opinion.

I have a 97 Cavalier and it runs hot it the cast isn't moving, plus the coolant boils over into the reservoir canister what causes this?

Sounds like your coolant is not flowing through the system. Could be a few things. Thermostat faulty. Blocked radiator. Water pump etc.

My problem is when the sun is hot and I stop my car and turn off the engines the water boil out.this only happen when the place is hot,in the night the water ok.

Your problem is the engine is overheating. On warmer days its causing the engine to overheat to the point your coolant gets too hot. There could several issues here. Start with your radiator as it may be clogged with rust or deposits from never having a flush. The next thing to look at would be the thermostat. these are a common part to go bad as they are exposed to varying temperatures throughout its life. The thermostat be stuck/seized in the closed position which in turn is not allowing coolant to flow freely around and through the coolant lines, causing the overheat and boil over issue you are experiencing. You may want to get this repaired soon or you this will cause irreparable engine damage; blown head gasket, warped head, cracked head. Etc.

Can cat. Converter cause 97 chevy cavalier to overheat?

The cat could restrict the exhaust flow and cause the engine to run hot.
You would also notice a reduction in power and the check engine light would probably be on.

Over heating

I assume you have checked the cooling system to ensure that first, that it is completely full of coolant (not just the overflow tank) with no air locks and second that there are no leaks anywhere and the radiator cap is in good condition. The heater hoses and those pesky little bypass hoses in the cooling system tend to go hard and split if they are over 10 years old, allowing coolant loss. Those spring type hose clamps tend to be less effective in clamping as the hoses become hard. Worm drive ones are the best to use.

If there are no leaks or air locks, the over heating could also be caused by a clogged radiator (more than 15% restriction in the radiator flow capacity will cause overheating problems), a faulty water pump or a faulty thermostat.

If there are no leaks and water pump and thermostat are working correctly, but undetected loss of coolant once the engine heats up, then it could indicate a problem with the head gasket (Usually caused by allowing engine to become excessively overheated when cooling system has run dry and warping the head) allowing very hot high pressure combustion gases into the engine water jacket, which super heats the coolant in the engine block, which then boils off, and is released via the cap. If the head gasket leak is bad enough it will allow coolant into the combustion chambers which will produce white steamy smoke in the exhaust and allow coolant to get into the sump while the engine is stopped. This is indicated by a white oil and water emulsion on the dipstick.

If unsure take vehicle to a cooling system specialist and have them do a pressure test and more thorough diagnosis.

1999 chevy cavalier overheats

When the engine has cooled down check the coolant level and make sure it is full. If the coolant is in the operating range, I would suspect one of two problems, water pump or thermostat. With the engine on check to make sure the serpentine belt (should be only one belt for your engine) is turning the pulley for your water pump is rotating without restriction.
The thermostat will allow coolant flow when it reaches operating temperate. You may be able to squeeze the hose and feel the pressure of the water flow when the engine is heating up. Be careful of loose fitting clothes and your body stays away from moving parts of the engine. If you have no flow check the thermostat first and if the flow of coolant is not circulating when the engine warms up you will have to drain the coolant to remove the pump to check the operation and replace if necessary.
The thermostat is inexpensive but you may have to drain and refill the radiator. If the water will not flow though the radiator it will not cool the engine. Follow the large radiator hose to the engine block. The hose connects to a cast iron elbow with two bolts holding it to the block. Drain the radiator fluid, unbolt the two bolts and you should see the thermostat. Clean off the old gasket off the block and elbow then bolt the elbow and new thermostat with gasket to the block to the manufactures torque specs. I would buy some radiator flush if it has not been flushes for several years. Fill the radiator with the correct ratio of coolant and water replace the cap then run the engine for 15 minutes and look for leaks or listen for hissing from the leaks.

97 Cadillac deville only overheats on hills it has a new radiator, water pump and rad cap. it runs fine on flat roads and at idle rad fans kick on about 222 degrees.

There's a few things I'd take into consideration. As stated in other posts, yes make sure transmission fluid is up to proper level. Also, depending on what engine you have, there may be an electric assist pump or even 2 in the system. On some, they have an electric pump to circulate coolant through heater core at idle to maintain proper heat , as well as another to assist mechanically driven pump when coolant temperature gets to approx 195F. Obviously when going up hills there is an added continuous load on engine, which will cause it to run hotter, thus I would expect that electric pump to be kicking in, and if not, may be the cause. Also the added load of climbing hills, creates added exhaust temperature, and if there is any restrictions, the results would be overheating. Quite often you may feel at least a little lack of power compared to what it used to be, or an increase in fuel consumption, or both when exhaust has a restriction. With that said, a weak water pump is also a possibility. Hope this sheds some light on what to pay attention to.

Overheating when driving no mixing of the coolant and oil

The three most likely thing's cause overheating are faulty thermostat,electric fan or clogged radiator. Only at has been overheat so much it boils dry that it will cause engine trouble. Most common problem's are blown cylinder head gasket or a cracked cylinder head.
mixing coolant and water depends on where the gasket has blown or head is cracked. You will first need to check if it actually is overheating. The reason is. If the head is cracked or gasket blown then you can get a false boiling which is compresion from the cylinders blows through the crack in the head or gasket causing the coolant to blow out of the radiator cap.Fill the radiator to the top leave the cap off then start the engine.If the water blows out then you will need to remove the cylinder head check the gasket is ok. If its damaged replace if not get the head checked for crack's. If no water blow's when you start it check the thermostat is working properly. To check the thermostat put it a in a saucepan cover it with water bring the water to the boil. It should open before the water boil's but near boiling-point. If its ok then start the engine again leave it running until it boils and check the fan is running. If that's ok then its radiator problem. Their is no way to check if the radiator is ok you will need to get a new one. One last point. If the cylinder head or gasket are faulty it was caused by overheating so by just fixing the cylinder head problem is not a cure it will overheat again. Check the three things I mentioned at the begining and told you how to check them. Hope this help's. Cheer's
