There are a few things you need to check:
First, make sure the cooling system is free of air. This can be done by loosening the bleeder screw while the engine warms up and closing it when only coolant spills out.
Also, look for any leaks from the radiator. Keep in mind it could be leaking internally.
Make sure the cooling fans are working. Check the fuses and switch the cooling/radiator fan relay with a nearby relay like the A/C compressor relay or another relay you know to be working. If the cooling fans aren't engaging, there may be a wiring issue or they may need to be replaced.

Water not circulating radiator engine running hot


Hi ytabaja97,
Sounds like the thermostat on the hose that goes to the top of the motor is stuck closed, or does not open completely. Try replacing the thermostat. Make sure it is correct for your Jeep, and that the seals on the thermostat housing are replaced correctly.
Hope you have no more overheating problems.

Ok, g35 coupe 06,52k miles Had over heating problem in april 2010,replaced thermostat, all's well. Now Jan 2011 overheating again, noticed upper & lower radiator hoses collapse, changed thermostat...


Heres a couple of things you can check. Start your car and remove the radiator cap,(before it gets hot mind you) when it reaches norm operating temp, look inside radiator to see if water is circulating. If its not moving, its a bad water pump. Also, youre hoses should never collapse, if they collapse when they get hot maybe you need new hoses? Finally, if those dont work, flush out your radiator. Open the bottom cockpit and use a garden hose and let it flush out the system while the car is running, about 10 mins should do the trick. If the radiator looks clean inside then it doesnt need flushed.

Top radiator hose hot and lower hose cold. car overheating. I've changed thermostat.


Either the water pump has failed, the radiator core is plugged, or the lower hose has collapsed and blocking the flow of coolant. Hope this helps!

Car is over heating changed thermostat water pump isnt leaking or making any noises


Ok well there are a number of possibilities. One to keep in mind is that some water pumps are really cheap and the fins will corrode and rust off leaving nothing behind to actually pump the water. If the pump really is working fine then there are two more possibilities. 1 the radiator is clogged, 2. there may be a head gasket leak. 3. you are sure your gauge is working right? 4. you didnt say what year or kind of car it is.. Is the electric fan working? When the engine is overheating, are both upper and lower radiator hoses hot? If the water pump or the thermostat are failing the upper radiator hose can be hot while the lower can still be relativly cool. If the radiator is plugged or the fan isnt working then both hoses can be Hot. There is also a remote possibility that water passages in the head gasket could be plugged.

Overheating


Yes they could. Some thermostats are bad out of the box and if you bought a rebuilt water pump it may never have been anything but cleaned.

What causes 1991 toyota camry to over heat? we put a new radiator in it last year cause the radiator got cracked. but it didnt start overheating til this year. so we changed the thermostat thinking it...


Change the radiator cap, it may be the wrong pressure rating which will cause the coolant to boil at a much lower temperature than designed.

Heating problem


If you changed the thermostat yourself and have noted that the lower radiator hose is cooler than the upper radiator hose, you may have installed the thermostat incorrectly or have purchased a faulty thermostat. A lower radiator hose that does not get hot (or as hot as the upper radiator hose) is a direct indication of a faulty thermostat. Please vote for this solution if you found this to be helpful. Thanks,

Overheating


there are three hoses leading to the water pump. the biggest one oviously goes to the thermostat housing, but the other two are much smaller 1 inch hoses, one of wich goes on the water pump and the other on the thermostat housing. if you follow the hoses one will connect to the upper part of the overflow for the radiator after hitting a T in the lines, that hose connects to the thermostat housing, and the other goes to the water pump its self.
