No, probably a bad thermostat or blown head gasket.

Please see my tip at http://www.fixya.com/cars/r5929960-s_thermostat . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.

My 1997 isuzu rodeo overheats and has no heat what's wrong


Could be that the heater core is clogged... for the car to operate at optimal temperature (not to cold, not too hot) all cooking system had to be working properly, I had a '97 camaro, it had 2 previous owners and I had heater core issues and also the hose that goes to the expansion tank was clogged, causing the water to build enough pressure to escape trough radiator cap... anyways they're two totally different cars but seems to me you need a cooling system flush.

They sell a kit which includes a T fitting that goes in the hose flowing towards the heating core, and allows you to connect a garden hose to push water through the system with radiator cap off so all can circulate and clean up. Being careful (water pressure in houses is more than the system is designed to withstand, for instance a radiator cap can be 15 - 20 psi, depending on area, some homes have above 40 psi) is a great diy little project. Alternatively you can pay a mechanic shop to do it. After a flush, drain the radiator from bottom plug and refill with coolant always. Don't run your system with water and don't drive an overheating car, it will blow a gasket and that's when you kiss your car goodbye, repair is not only expensive but blown gasket might leave sequels on engine.

I have replaced the the Thermostat on my Chrysler 300 with the 5.7 Hemi Engine. It still over heats. Is there more than one thermostat on thi engine?


You didn't state when it overheats, if it is while driving the fault can be : belt driving water pump slipping , lower radiator hose collapsing, most common is clogged radiator. Start the engine with the radiator cap off when it is COLD and observe the flow in side. If you see really fast flow of coolant you have the bottom portion of the radiator stopped up. The only way to know is to remove the radiator and have it flow tested.
A blown head gasket or cracked head will cause steam to come out of the exhaust, water in the oil (milky). If it is running hot while idling , check fan to see if it is turning as it should when it should. Older cars have fan clutches that go bad, newer ones have temp thermostats that go bad.

I have an 1997 chevy camro rs w a 134000 miles that is overheating the engine an water pump has been replaced an i stil cant find what is causing it to overheat


It could be the thermostat not opening and closing as it should. Or it could be a bad overflow/radiator cap. If the cap starts to go bad, it won't hold pressure and this will cause overheating. Good Luck. There are other major issues possible, but hopefully it's not. Start the engine cold and as the engine warms you should feel the thermostat open and water flowing as you hold the radiator hose, just be careful around moving fans.

What are all the possible thing that could cause overheating in a Car to the extent of water boiling and as a result ogt the radiator bursted?


1.If your radiator burst replace. 2.With the car COOL, open the radiator cap or overflow and fill it.3.Leaving the cap off, start the car and let it warm up as you keep the radiator topped off. 4.Once it wont take anymore and your sure the car is completely warmed up, reinstall the cap.5.Everything else your gonna have to hurry on or your car may start overheating. Grab the top hose and squeeze it. If you can't almost grab it till it closes then you have a bad thermostat. Replace it, if you have any doubts, pull it off the car and boil it inside in a pan of water, you should see the spring move and open the plate.6.If thats not it check your water pump for flow,bearings, and belt condition.7.Also check all your fluids for antifreeze contamination, mainly the oil, as this can be a sign of a blown head gasket which is very common on these years of Gallants. REMEMBER your cooling system cools by building pressures of over 300 psi, and any flaws in your radiator during a overheat will blow! Hope this helps ya buddy! Shannon(Shizzo)

Hey, I'm not a car guy at all but I'll try my best to describe the problem. I have a 1986 Buick Century Estate Wagon, and for some reason it likes to randomly overheat/probably for a certain reason. My...


Probably thermostat sticking or bad water pump. CK the belt to the water pump to see if it's loose. If the thermostat sticks, water can't be pumped thru the motor, overheats and overheats the radiator causing hot water or steam to build up pressure.and the relief valve will open allowing the peessure to be relieved and blows coolent everywhere. If the radiator overheats turn off motor wait until the radiator cools before removing cap. been there, done that-------once

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

1997 suburban overheating


Hi my name is Allen. Your hose blowing like it did can be 2 different problems. One your thermostat could have stuck causing it to overheat to the point of building so much pressure within the radiator that it caused the hose to blow. The other possible cause is you may have a blowed head gasket which is very expensive repair. The water not moving through the system with the hose off, could be because the water is going in the oil pan, pull the oil dipstick and check to see if the oil looks milky like a real light tan color and if the oil is way above the full line on the dipstick. If it is you have a blown head-gasket. If it is not, I would suggest replacement of the thermostat and see if that repairs your problem. You may contact me for futher assistance through FixYa.
