The radiator has been changed to a new one and all the sensors changed and coolant added but it still heats up. The water pump and radiator hose are new-was told we need to bleed the coolant system and change the bleed valve. Can you tell me where it is located? After coolant was added and car ran the water came out of the resevoir,very rusty looking water. Can you help????
Was the thermostat changed? I would suggest replacing the thermostat refill the system with new coolant and purge the air out of the system.
I am a 64 yr old grandma who bought a lemon and even though I have had many cars in my life that overheated the problem was never this complicated. My friend flushed the system again until water was clear and took out the thermostat and it doesn't overheat anymore but-the temperature gauge registers way over hot before you start the car and after started it goes down about 1/4th of the way. It's a bit too weird for me. And what if he puts the thermostat in again, will it overheat once more?? Your answers are VERY helpful and I really appreciate your time. Thank you-
Not a problem that's what we are here for. Now, I'm against not having a thermostat the thermostat should be installed it should've been replaced with a new one. Not having the thermostat may cause other issues and will affect fuel consumption. After replacing the thermostat purge the air out by adding A 50/50 mixture of coolant and water with the engine running until the radiator is full and the fan cycles atleast 2 times. Without a thermostat water may flow to fast through the engine and not have the ability to absorb the heat from the engine and on the other side of the spectrum the hot water may not have enough time un the radiator to be cooled resulting in an overheating condition. Whatever you do good luck to you.

SOURCE: Trying to flush the radiator--cannot find the bleed valve for coolant.
The drain should be on the drivers side at the bottom of the radiator, facing the driver. It's a plastic "wing" that unscrews. There should also be a bleeder for exhausting the air from the system when you refill. The bleeder I'm familiar with is a brass screw screwed into the thermostat housing. (where the top hose attaches at the engine)
SOURCE: coolant not flowing to engine, overheating after replace radiator
Remove the thermostat and then try it. If it works then replace t-stat
SOURCE: I am losing coolant, not from the radiator and not
you could have a blown head gasket and coolant could be leaking into your combustion chamber.
rent a radiator pressure tester and see if the cooling system will stay at constant pressure. If the pressure drops you have a leak, and it could be your gaskets. pretty costly to repair.
make sure you have not blown the seals on the engines water pump. when they go out, the burst disc on the pump open and gush coolant everywhere.
SOURCE: bleed coolant system
Old methos id to leave the raditor cap off and squeeze the coolant hoses to get the air out.
SOURCE: car overheating, coolant in resevoir cold,
First-change the thermostat and bleed the system.If the problem is still there change the water pump.
