F your engine is overheating, Try this procedure:

  • Dirt and debris can get lodged in the radiator air flow paths. This can block the radiator and cause your engine to overheat and damage the engine.

  • The thermostat can be stuck close. If you feel the upper hose very hot and the lower hose cooler than normal, it may be a stuck thermostat.

  • Make sure the radiator and the overflow bottle are filled to the proper levels.

  • Bleed air from the coolant system:This is best done by running the engine with the radiator cap off until you see when the air bubbles stop coming up.

  • Check the radiator fans: The easiest way is to turn on the cars air conditioner and turn up the A/C fans. Both radiator fans should come on when the A/C starts

  • Make a pressure test by using a pressure testing tool (available at most auto parts stores). Use the pressure shown on your radiator cap. Most cars are 16 PSI or less, so don't exceed that pressure. Replace the radiator cap if it doesn't hold the pressure.

SOURCE: losing radiator fluid. is it water pump or

This is a water pump or worse yet, a head gasket issue which is very common on the 1998 deville. I had the same exact problem but mine was fortunately a water pump. I was leaking fluid and adding anti-freeze every 3 days. I had a pressure check and it led to the water pump. Be sure to have the gaskets replaced within it as well. The thermostate is located in that housing too so have them check that since they're already in it.

SOURCE: 1997 cadillac eldorado running hot

Make sure you put in the correct temp thermostat. GM usually has 2. A low temp and a high temp. Most shops will give ya the high temp just because thats usually what the book calls for. you might want to try a low temp. Also, sometimes, when a car runs hot and everything has been repaired....well, almost everything......it might be the head gaskets. And those my friend are no easy task. But..somewhere to start. have your cooling system pressure tested. Only way to really know for sure. Oh..also make sure your fan is working!!!! You might have a faulty fan switch.

SOURCE: 1996 cadillac deville overheat..radiator?

Check for coolant flow at the Purge line,this is a common problem on the Northstar.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.

SOURCE: i have a 99 cadillac eldorado it is overheating i

Hello: Open hood, stand in front of car look on left side (driver side) of engine toward the radiator, there will be a black metal guard, under the guard there will be a small belt. This is the belt that drives the water pump. Make sure the belt is there. If belt is there start car and with engine running check to be sure belt is turning and that the water pump is turning. If all that is okay then you may have blown head gaskets. To check head gaskets you need a sniffer tool to smell the engine coolant which will tell you if you have exhaust gas in the coolant.

2002 dodge intrepid.if water pump is leaking will this car run hot


If you lose sufficient radiator coolant any water cooled engine will overheat as will yours. You do not need to lose very much coolant for an overheating condition to occur.

If you allow the engine to run in an overheated condition you WILL cause very expensive engine damage many times what it will cost you to have a new water pump and new WP gasket fitted.

Hi my camry 300sei boil the water out but the haetgage seems ok when I open the rediotor cep the water is empy and the car is warm can u please help!!!!


When cold fill the radiator with water and leave the cap off. Make sure that you have all the air out.
Start the car and watch the radiator, you are looking for air bubbles coming out of the radiator. If you have a steady stream of bubbles appearing you have a blown head gasket.

Overheating and no heat


With what you describe sounds like the hot water is just heating up but not circulating and cooling correctly. Possible causes, airlock, faulty water pump, check fan belt tension, not broken etc, blockage in engine water way or collapsed hose. Are you losing water at all? Head gasket?

Radiator overheating


If the overheating is only occasional, it sounds like the radiator still has some blockage that moves around and plugs up again. Try flushing it backwards again. If it continues, consider a new radiator. A radiator is cheaper than head gasket work, which may happen if it keeps overheating.

Took out the thermostat, replaced the radiator, the water is circulating in the radiator but it is still running hot. what do i do next?


Overheating can seriously damage a car's engine if left unchecked. Although overheating simply means that a car's engine temperature exceeds normal operating temperatures, the causes of overheating are varied. What follows is a brief list of some of the most common causes of engine overheating.

    Faulty Radiator
  1. A car that overheats will often have a faulty radiator. A radiator is responsible for cooling hot engine coolant that picks up heat from inside a car's running engine. A radiator "radiates" the heat from engine coolant out into the outside air. A faulty radiator loses its "radiating" effects and allows engine coolant to become overheated, thus rendering it ineffective at adequately cooling and engine.
  2. Faulty Water Pump
  3. A faulty or malfunctioning water pump prevents adequate engine coolant flow and can cause a car to overheat. A water pump serves to pressurize and propel engine coolant throughout a car's engine and radiator to increase the heat-reducing capabilities of engine coolant. A faulty water pump loses its ability to adequately pump and propel engine coolant, and can cause a car to overheat.
  4. Coolant System Leaks
  5. A leaky engine coolant system reduces the level of circulating engine coolant, which increases engine temperature and leads to engine overheating. Radiators, water pumps, and coolant system hoses and seals--all of these coolant system parts can develop leaks, which can result in low coolant levels and engine overheating.
  6. Faulty Thermostat
  7. A car thermostat regulates the flow of engine coolant. A thermostat is a heat-sensitive valve that opens when a car engine reaches a set operating temperature and closes when a car engine is cold and warming up. If a thermostat gets stuck in the closed position, coolant will be prevented from reaching the engine, which will quickly lead to engine overheating and potential engine damage.
  8. Low Engine Oil Level
  9. Engine oil, in addition to lubricating an engine's internal parts, helps to keep engine operating temperatures reduced by eliminating friction within the engine. If engine oil levels are low, friction and heat build up inside an engine, a condition that causes increased engine operating temperatures and can lead to engine overheating.

Hello and welcome to FixYa!


If you have overheating problem, it can lead to multiple issues. You may be running on low coolant that's why the vehicle overheats. If that's the case, please add coolant and make sure that it sits on the right level, too much coolant can cause overheating too for coolant will overflow.


The vehicle may have a faulty or worn out radiator blower motor that's why it overheats. If that's the case then you will need a blower motor replacement to resolve the issue.


If the radiator is clogged with dirt and rusts this issue occurs too. The coolant doesn't flow normally on the cooling system if it's clogged. If that's the case, I strongly suggest that you have the radiator flushed to drain out dirt and rusts. If you think that the radiator served you enough then it's better to have it replaced.


Please do check the radiator hoses, If you have worn out hoses it can cause coolant leakage which can result to overheating. A tiny hole is good enough for the vehicle to overheat.


A faulty thermostat sensor can cause the issue too. If you have worn out thermostat, the fan may not trigger that's why the fan won't work when under stressed conditions. A blown radiator blower fuse can cause this issue too so I suggest that you check the radiator blower fuse and replace it when necessary. What causes the radiator blower fan fuse to blow? It's because of a failing radiator blower motor, If that's the case have the radiator blower fan motor replaced.


If the fluid in radiator doesn't circulate then it means that you have a blown head gasket or a faulty water pump. I suggest that you go for the water pump replacement first specially if you think that it's near the end of it's service life. Usually, water pops out the radiator when engine is reved (a sign of faulty water pump and possible blown head gasket).


Hope you find this information helpful enough and thank you for using FixYa! Have a good one!

Car is overheating, thermostat was changed and the radiator was flushed, car does not overheat while idoling, but when you start driving it overheats


It sounds like water pump may be your problem. It circulates a 50/50 mixture of glycol (or some form of) and water through the engine block and cylinder head and back through the radiator. In the radiator the mixture is cooled when air passes over the fins of the radiator. This is accomplished by driving or a mechanical/electrical fan when stationary. The water pump also circulates the mixture through the heater core giving the car heat. If the water pump is not circulating the water back to the radiator to cool, it will overheat. More heat is caused by the engine when driving (much less heat when idling), hence the overheating while driving.
I hope this helps and good luck!

1989 Ford Escort GT overheating


Sounds like to me it would be your water pump before a heater core. When the water pump goes out, it stops pumping the coolant through the system which is what would cause it to still overheat even with the thermostat out. Change the water pump and you should be good. Let me know if you have any other questions. Thanks for using FixYa!
