This is more than likely a failed water pump. The OE pump has a plastic impeller that tends to seperate from the shaft and doesn't pump coolant. It is easy to check through the thermostat hole. You can stick your finger through the hole and feel the impeller. If the pump is bad you will be able to move the impleller with your finger through the thermostat hole.

I have found that the best way to eliminate the thermostat as being a route cause to to run the car without it. Outside of this it sounds like it may be a water pump issue.

2002 pontiac aztect overheating has new thermostat and water pump


Try removing the thermostat and reverse flushing the motor, Actually try flushing in both directions, this will tell you if you have a circulation problem but 1 thing you should know is that the water goes in the water pump and out the thermostat, try running it without the thermostat and check your water flow

Water doesn't seem to be running around the system and is getting overheated. From the water bottle the hose to the engine is cold but the hose from the engine is hot as tho there is an airlock. is this...


there are a few possibilities .. first a bad thermostat is likely if the hose attached there isnt getting hot ... if the thermostat has been changed recently then make sure its in the correct way .. the spring or thermal sensor goes toward the engine .. the flipper valve goes toward the radiator .. make sure its not blocked by the gasket .. another possibility is a bad water pump .. an internally collapsed radiator hose is also possible ... make sure the cooling fan is turning on and actually moving air when the radiator gets hot ... you dont need the fan while moving but while idling the radiator will overheat if its not working .. you also have to check the pressure cap .. if it doesn't built pressure then the coolant or water will boil before the fan turns on .. when the engine is hot the radiator hoses should be hard from the pressure .. ... your problem sounds most likely a bad thermostat ..

My pulsar in overheating put new coolant in no change fans dont seem to be working but engine was hot and gauge showing only halfway, cant find the thermostate is it in the housing the top hose is...


Make sure the fans are coming on or it will over heat. If the fans come and the gauge is reading hot check the thermostat. Follow the top radiator hose to the engine block it probably has 2 bolts holding the thermostat housing on.

1994 Honda Civic LX\overheating within 2 mile drive


Remove and raise upper hose at thermostat end and remove lower rad hose.
Fill rad with a hose and watch for flow from bottom rad hose and/ or bottom rad hose connecton.......water should fall though rad easily.
Honda rads are cheap.....any restriction....replace rad.

Remove thermostat....fill thermostat housing with hose and watch for water flow at bottom rad hose.
Flush good.

Remove heater hoses.......flush back and forth until a good flow is present "With heater control set to hot" if no or poor flow....replace heater core.

Stop leak can plug everything.

Also.......not likely causing over heating....but ....at your mileage,if you do not know if the timing belt has been changed.....CHANGE IT NOW!
Water pump is optional at this mileage.

My VW Cabrio is overheating after 1-2 miles. Coolant in recovery tank is boiling by this time and making bubbling noises. Someone changed radiator hoses, flange, some housing. They are saying that radiator...



Run the engine and look at the header tank , is there lots of air bubbles coming back out of the water if is then the head gasket may have split and that is down to either a can of Radweld or a strip down repair

If the radiator is not uniformly hot them I would go for that as your problem

Normal operation is that the engine starts the thermostat is closed , engine block heats up and opens water starts to circulate around the block

So to check that you need to fill the radiator with cold water run it for a few minutes check the bottom hose it should be cold

The stat opens and the bottom hose should get hot as the water from the block is pumped into the radiator for cooling.

The radiator should get hot all over and the cooling fan should kick in when the sensor hits the over limit stop.

If that does not happen then get someone to remove the stat altogether (It is only there to get the engine block warm quickly in cold regions )

In which case the bottom hose should go from cold to warm to hot

Engine overheating-----1994 Olds Cutlass Supreme 3.4 liter v/6


There seems to be an air pocket or no antifreeze in engine block. Try this method disconnect upper radiator hose and pour water directly into hose down into engine block until it full. when its filled reconnect hose and fill up radiator. as the vehicle warms up open bleeder valve on the thermostat housing and release air from system. open slowly and BE VERY CAREFUL WATER WILL BE HOT, bleed until you get a steady stream opening and cosing valve. However if all of this don't work. You may have a bad pump. Good Luck

Heater blowing cold air


My 2005 Nissan Sentra 1.8s with 55,000 mi. blows cold air from the heater. Coolant not circulating in engine. Lower hose stays cool to touch. Both heater hoses cold. Changed thermostat - didn't fix it. Coolant not leaking or dirty. None in oil - no oil in radiator. Changed worn water pump belt - pump spins freely with no noise or resistance. Cooling fans come on after warm-up. Temperature gauge stays in normal range then jumps to hot and back again. Coolant good to 10 below - didn't freeze here yet. No other problems or repairs to car. Afraid to drive and make worse. Help!
