Check to see if the fan is actually coming on. (possible bad sensor) Also, check to be sure the thermostat isn't put in backwards. The Coolent system also needs to be bled, kinda like brakes. There are two bleeders. they are both on the top of the engine were the hoses connect. Mine were both broke off. They are dealer items only, cost $9 each. Open the one on the left as you fill the radiator. when anti freeze comes out with no air, close the valve. Start the car and open the one on your right(drivers side) let out air then close. I had to play around a bit with it but it is now running at the right temperature. Anti freeze sprays all over the engine but that can't be helped. Good-Luck
Low coolant, inoperative water pump, head gasket failure, inoperative radiator fan, etc.
There could be several things that will make your 2005 Grand Cherokee Limited overheat even if you just changed your radiator. There may be a head gasket blown.
A bad thermostat can cause an overheat. A bad temp sensor can show an overheat when the temperature is normal.
Low coolant, inoperative radiator fan, stuck thermostat, slipping belt, failed water pump, etc.
low on water or bad thermostat
Intake manifold gasket leak? (Never heard of a heat sensor). Many possibilities.
2000 Pontiac grand am se keeps over heating I changed the water pump, the thermostat, radiator cap, head, and it is still over heating. make sure thermostat is going the right way , spring gose to the motor
I do not have a Grand Marquis so my engine does not overheat! Fords and Ford products tend to overheat and always have! Let's check a few things. How long has it been since you changed the thermostat and the coolant? Those two things are the most likely culprits. What is the condition of the hoses? Have those been changed in the last several years? If you have changed the hoses, the thermostat, and the coolant, and it still overheats, then it is time to take it to a radiator shop and have the radiator rodded out. ========================================================== I have been driving Ford models for over 40 years and have never had an engine overheat . Don't forget the basics , engine cooling system level etcetera . Check for a fan clutch problem , a problem with the water pump not circulating . Ford also states that if you exceed 60% antifreeze in the distilled water / antifreeze mix that it could overheat in hot weather
The radiator fan is not working,or not working properly,or possibly the thermostat is bad.But,usually if the thermostat is bad the engine would still overheat even if you speed up,so I would suggest testing the radiator cooling fans.
I suspect that either your thermostat is plugged with debris from the radiator change or that the thermostat was replaced backwards. The spring side should be towards the block.
We don't know what relay you are referring to. Check your thermostat and radiator fan. Fluch out your cooling system.
3.1 engine leaks at the intake gasket
no water in radiator? when is it over heating and in what conditions
The thermostat is located near the intake on a 1999 Pontiac Grand Am GT. The thermostat can be located by following the upper radiator hose directly to the thermostat.
Locate the radiator. Locate the upper radiator hose. Follow it to where it connects to the motor. That's where your thermostat is. In the little housing that your upper radiator hose connects to.
On a Jeep Grand Cherokee v6, the thermostat is located in the thermostat housing. The housing can be easily located by following the upper radiator hose to it.
Could be the rad. , the thermostat, hoses, fan. You have to check all.
Follow the top radiator hose to the engine. You have just found the thermostat housing. Remove the 2 bolts and replace the thermostat and gasket if your engine uses a gasket. Be sure to note the orientation of the original thermostat before removing it.
if you take the cap off of the radiator it is in there actually no its not. follow the top radiator hose to the engine. that is where your thermostat is. you will have to drain the radiator, remove the engine side of the hose and remove the thermostat housing to access it.
could be alot of things, either check debris in the coils of radiator or check the thermostat. Make sure shraud is undamaged or you can flush the motor and radiator, a radiator flush can be done yourself or at any quick stop lube shop
At the point where the upper radiator hose clamps to the engine is the thermostat housing. Inside is the thermostat.
if it is a four cyl it is most likely under the passenger side of the engine at the end of the bottom radiator hose it is best to take of the exhaust manifold to replace it is possible that it can overheating if it it bad I have a 1996 Grand Am SE, and mine runs hot too. Its probably not the thermostat, if not, then try flushing the coolant system, or the radiator might be clogged up.
thermostat is located inside thermostat housing, this is where the top radiator hose connects to engine
The thermostat on the V8 is under the housing where the lower radiator hose attaches to the engine. The thermostat on the six cylinder is under the housing where the upper radiator hose attaches to the engine.
Drain all the coolant from the radiator. Disconnect the upper radiator hose from the engine. Remove the aluminum thermostat housing. Should be held in place with 2 bolts. There you will find the thermostat.
