    Im not so familiar with the part but where is the head gasket and the thermostat housing located in my car in relation to my problem.

    Thanks steveepb im following you now, im looking from the top of the engine and i could see the leak coming from on top of the oil pan on the left side.

    I have the same problem, but it is hard to detect. For examining the water pump the weap hole looks as though it is at the top of the water pump. And the fluid leaks beneath. As if it were coming out of where the gasket and the pump are joined at the engine. I have been trying to find some pictures on the engine.

    Looking at the engine from the hood, it appears the leak is originating at the component that houses the belt spindle (?) between the A/C and the tension part. What is that and how do I fix it?

    it must be running off the engine someplace higher, can you follow it back to find exectly where it's coming from?

I am having similar issues with my 1997 Cavalier. It is however running hot...especially when I turn on the a/c. It takes about half a gallon of coolant a day and I do drive it quite a bit (never run it hot though). Did your problem end up being radiator hose, water pump or head gasket? I am getting nervous. Like you, I bought the car for $900 and want to do whatever it takes to keep it up to par and not let anything go to far. Any advise and/or experience would be greatly appreciated!

Thankyou for the reply post. I found it was the water pump and just because it appears that the weap hole is at the top of the water pump it is in fact there is one at the bottom. But with further inspection and replaceing the water pump I was informed that I have a head gasket leak at the front of the engine. It is at this time small. And will require $$$$$$$$ ( $ 800.00 to $ 1300.00 est. ) to repair, I paid only $700.00 for the car and to this day have put in $1100.00 to it. But I love the car! But if can survive till the taxes come next year, I can do it. Baby it and don't drive it much, God willing it will be ok.

I'm placing the order of the places to check in the order of the most frequent problems. The water pump is on the side with the belts, thermostat and it's housing is located on the motor where the rubber radiator hose connects to it, heater hoses- two hoses around 3/4 inch one off the radiator, other off the motor into firewall, freeze/frost plugs-there are several of those on the motor all of them right above the oil pan on each side, then there are the head gaskets. These are inbetween the motor and the heads. To find these, look right under the exhaust manifold, if the coolant is coming from that area, on either side, it's the head gaskets.

    It's on top of the oil pan on the passanger side? And on that car that should be where the belts are, correct? If so, run the car for a little bit, then shut it off. Check the water pump pully for wetness. It should state in your manual which one is waterpump pully. Shoud, not guaranteed. If it's really wet there, then your pump is bad.

Alright, the best way to find a leak is to fill the reservoir and get it up on ramps or a car lift would be excellent. Start the engine and find out where the leak is coming from. Most common leaks are simply just bad hoses or busted fittings. However, there could be a blown head gasket, hole in the radiator, or a bad seal on the thermostat housing.

I've even seen where a bad thermostat was causing high pressure in the water system and ended up blowing the excessive pressure and water out the overflow, even when the water was actually low. So, find the location of the leak. Use the method I told you and it will help you find the exact location. Then you can proceed on fixing the leak.

Hope this helps out! :)

My 02 chevy cavalier overheats without a sign of leaking coolant

Not sure I am with you on this. The cooling system is designed to run between 190 and 210 as a normal range. Above 210 and the radiator fan should start up. Anything over 230 is considered Hot.
Is the radiator fan coming on around 220 degrees ?

Chevy 2005 cavalier low coolant light keeps coming on and the coolant reservoit tank is empty after only 200 miles. what is causing this?

  1. Check the hoses and clamps going from the reservoir to the radiator and from the radiator to the engine. Make sure they are flexible and in good condition.
  2. Check the reservoir and radiator for leaks.
  3. Replace any parts they may be failing. If no leaks are found proceed to next step.
  4. Check engine oil. If oil has coolant in it you may have a blown head gasket or crack in the head or engine block. Another sign of a coolant leak into the cylinders is white smoke coming from the exhaust after the engine is warmed up.

1999 chevy cavalier is over heating and the resiviour is boiling what would cause this?

If there is no coolant lost on the ground or you are not having to add coolant to the system but it is still boiling in the reservoir, it may not be completely full or it has a head gasket leak. Have a coolant system pressure check run on the system or go to autozone and rent a coolant system tester to do it yourself. If it does the system does not hold pressure and the leak does not appear to be external, it probably has an internal leak most likely the head gasket.

Car overheats, losing antifreeze...the overflow coolant reservoir leaks out onto the ground when I try to put antifreeze in there - so could this cause my car to overheat? I have had the antifreeze drained...

Hello, if your car has a blown head gasket and exhaust is entering the coolant system, it will continue to run hot until it is repaired. Using pure antifreeze will make it worse. It should be at least 1/2 water. If the coolant reservoir didn't leak you could probably drive a few more miles, but not many, before it overheats again. All that is doing is giving you a little more capacity. If you continue to run the engine hot you are going to do more serious damage to it.
I suggest you have the head gasket replaced. That stuff you put in there seldom works, and if it does work, it's only temporary.

I hope this helps.

You'll have to get under the car and look. Could be frost plugs, block heater, head gasket... lots of things. But you have to see where it origionates. It could run a long way before it gets to the ground by your right tire.

I have a 1997 Chevy Cavalier 2.2 Engine. After changing my IAC Valve, TPS, Thermostat, my coolant light still stays on. Car doesn't overheat.

If the coolant level is o/k check level indicator sensor which should be on the rad. It is a one wire sensor. Hope this helps. Moe
