Overheating problem

i would take a close look at the water pump
if the water isnt moving through the system it basically becomes a kettle
thats why steam comes out of the bleed nipple

I have a 2005 Buick rendezvous that has had a radiator cap and radiator water pump intake gasket flushed radiator why is it still running hot

Being it appears from your post the intake gasket was changed (I'm hoping it was the lower intake gasket) then I would suspect the thermostat.

IF the thermostat was changed then another, and pretty common cause can be an 'air lock' in the cooling system.

There should be 2 bleeder valves or screws located on the engine.
One should be on the thermostat housing and the other should be located above the water pump.

There are a couple of different methods of bleeding the air from the system. One is to do it while the engine isn't running, the other is while the engine is running and starting to get warm.

Both methods can work and I've used both.

The method with the engine not running I usually use while I'm refilling the cooling system after I've made repairs.

The method with the engine running is the one I've used if there have been previous repairs done but the engine still overheats or the heater/defroster doesn't put out any heat, even though the temperature gauge says the engine is warm or getting hot.


Hopefully this video will show you where the bleeders are located.
Hope this helps.

Opened bleeder valve on charger 2.7. Only vapor comes out. Bad pump or thermostat?

Continue to add water until the vapor "lock" is purged of all air. All coolant bleeders are supposed to reside higher than the radiator/coolant filling area...the coolant should flow out of the bleeder valve before tightening the bleeder shut.

Car started knocking really bad got a cylinder 2 misfire code after opening coolant bleed valve with enging hot

Okay, it may be due to overheating, that may be the noise you heard, lets hope. first allow engine to cool, open radiator cap or the resivoir cap, which ever is the fill, remove the bleeder at top hose and fill radiator slowly until coolant comes out bleeder.

note if water pump was replaced due to leaking and engine was overheated at that time then it may be a good idea to replace the thermostat .
after filling is done start engine and allow it to run. watch temperature if temp start to climb past half way shut engine down and let sit for 5min. then restart and check level, in res do not open cap . feel air from fan and see if it is getting hot, this may take up to a half hour but do not drive,

A few questions, does this jeep have an electric fan?
when you heard the knocking was engine temp hot?
If you start jeep cold does engine knock?
Did this jeep get a new thermostat with waterpump job?
did it overheat when pump went bad and why did water pump get replaced?

sorry for all the questions ,just trying to get all the info to help you .

I got a 98 Buick century I change the water pump. Thermostat hoses and top and bottom gaskets I put water on the radiator and spitsit right back would you toll me what could be the problem thanks

You have an air bubble inside the cooling system. There is a little bleeder valve by either the thermostat or where the hose goes into the motor. It should look like a bleeder valve on the brakes or just a thumb screw. Anyway you need to open that bleeder when the motor is cool while you are adding the antifreeze. Leave it open just until all air bubbles come out and it's straight antifreeze. Then close it and finish filling the resevior. Run the motor about 10 minutes. Let it cool and then recheck fluid level again.

Where is the bleeder valve

bleeder valve for the fuel injection is on the fuel rail
for the anti-freeze it should be on top of the thermostat housing
if not there check the pipe above the water pump

Does my cooling system have a air bleeder valve? I have filed my system with antifreeze, changed my water pump, thermostat and still it heats up quickly.

According to my data base it has one, but it doesn't give the location. The ones I've seen are located on the thermostat housing or on the engine close to it and they look like a brake bleeder valve.

My 04' over heating when idoling and ac is on

Fixed problem HERE........................

We changed thermostat, belts, water pump, hoses... you name it we changed it nothing worked. Just before we ordered a new radiator I took a few pics sent them to my dad and instantly he said to remove the bleeder bolt then fill radiator. That's it guys months of overheating a lot of money and hours of work when in the end it was so simple, cost nothing and took 2 mins.

Turns out most the Nissan motors have a type of bleeder bolt or something (not sure what its called exactly) on top of the motor and that should be removed while filling radiator. step 1 wait till engine is cooled down all the way. step 2 remove radiator cap. step 3 remove the bleeder bolt on top of motor (look around for it. Its just a little old bolt all alone) step 4 slowly fill radiator until coolant/water to come out of the bleeder hole. step 5 put bleeder bolt back in. step 6 put radiator cap back on. That's it. Good luck

if you do not do these steps air get caught in the system and when heated turns to steam. and your radiator cant circulate that steam because the hot air raises. The steam will just sit at the top of the motor and block the coolant/water from circulating through the radiator like it should. Without it passing through the radiator correctly it will not cool. Having a new radiator helps because when they installed it they probably filled it correctly (by removing that bleeder bolt). They knew they could have just filled the old one correctly but there isn't any $$$money$$$ in that for them. trimble7383_0.jpg

Coolant pouring out surge tank

if one radiator hose gets hot and the other doesnt, the the thermostat is shot, but you said you replaced it, it is possible the thermostat has been put in backwards
