Thermostat is probably bad.

Without knowing what year your car is, the thermostat could be here:

OVERHEATING - 22a4d870-a415-4d5e-8edc-3ee4990155eb.jpg

.To test the thermostat, put it in a pot of boiling water. If it clicks, it works. If not, then replace it.

SOURCE: overheating

1. start the engine and leave the radiator cap open.
2. put a cardboard cover or a rug in the front of you radiator.
3. let it runs 20 minutes or more, see if it is overheated and see the water or coolant in the radiator circulated or not. If not, as soon as you have already changed water pump. thermostate and check the hoses, no leak, I think your radiator was blocked.


Did you put stop leak before?

hi jasso, I would recommend checking the water pump if you see no flow in the radiator. Make sure when you fill up the cooling system, that you fill it cold, and that the vent screw in the radiator is loose. fill system until fluid comes out the vent screw. tighten the screw, start the car and have someone run at 1500rpm and check for flow.also, make sure that you have your temp setting full hot and blower on middle speed so that you don't trap air in the heater core.

you could have a bad hose, check the upper and lower hoses and hake sure they are not caving in on themselves. sounds like it could either be that or you might have something cloging the hoses. run the engine with the hood open so you have the pressure build up, and look at both raditior hoses. see if they are bulging out as pressuer gets built, or if they cave in .

SOURCE: engine overheating

The same thing happened with my 01 cavalier. My dad replaced the thermostat and it did the same thing. Then he discovered that there is something called a temperature control sensor that had to be replaced because when the thermostat froze open, it destroyed the sensor. It was a lot cheaper than any of the other parts and once it was replaced, it worked fine.

SOURCE: Kia Sedona overheating. New radiator/compressor. Now what??

Hi,
To start with you have to do this:
With the engine cold, start the car and say after 30 to 40 secs. open the radiator cap.
Carefully and slowly, cause if the problem is either in the cylinder block or cylinder head this shows immediately as water would be compressed in the radiator ( even though the motor is still cold ).
If nothing happens and you would not notice any bubbles in the radiator, then we have to talk again.

My x585 overheating if I hose down the radiator it cools down but I don't know why it keeps overheating.


if its overheating but staying cool at radiator then its more likely to be a failed thermostat, the thermostat should open up to let more water though to cool engine down, if it becomes faulty it does not open so there is inadequate flow and courses on over heat. and weak part is the header tank, it can also cause rubber pipes to pop or split. and blow the head gasket, so don't drive until thermostat is checked and changed, air in system should be released but the header tank it has a valve fitted to let off steam,

Serpentine belt tensioner pull


Belts only drive the water pump and other accessories and do not cause overheating. Have a pressure test done on the cooling system. Have a compression test done to check for head gasket or cracked head. Have a flow test done to check for blocked cores in radiator .check external fins of radiator to see if they are flaking off. Flushing radiators doesn't work because once the cores are blocked up there is no way to un block them. If you have a viscous fan hub have it check out as they stop driving after a period of time.

Overheating when driving down the road


Most common cause is a internally plugged radiator.
The water and coolant often react negatively to the metals and rubber inside the passageways to clog the radiator over time. If you wish to try to "reverse flush " it yourself, ask "fixya".
Other causes may be: Stuck thermostat, plugged fins of radiator outside, water pump slipping or starting to fail by "freezing up",
loose or slipping serpentine belt, and problem with the engine cooling fan.

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.

2001 subaru legacy overheating


Well it sounds like you have covered most of the bases.
One thing that could cause overheating is a restriction in the exhaust.
Do you know if the radiator fan is coming on when the engine reaches 220 degrees ?
How long can you drive it before it starts overheating, and does it boil over when it does ?

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!
