SOURCE: water pump replacement in a 2002 Mazda MPV

The reason is the water pump is driven off the timing belt, extra parts and allot more labor. No the eng does not have to be removed, labor time around 4 hours, parts about, about $125 US for parts, if it is a dealer add $75 US

You probably never cleaned the cooling system out.

If you have not get it done by pros.

It seems something is blocking the flow. If the water pump went bad you will know. Rarely ever heard a impeller breaks off like you think. The bearings and the seal break first.

Check and see also if the heater valve is working.

As for the over heating even new thermostats fail. Reverse flush is needed or the procan measure the pressure in the radiator cooling system and edetermine if there is a engine pressure problem. Tools and experience is the key in the game of diagnosis.

SOURCE: engine overheating

The coolant flush on radiator doesn't do any good. Since you have changed all the key components and still gotten overheated, then the root cause of the problem is the radiator. It got clogged up in small tubes blocking coolant flow. No matter how good the water pump is working but the radiator got clogged up, coolant is not circulating therefore the heat from the engine can't be dissipated to the radiator. Replace your radiator, don't even think about rebuild it. It has been used for 11 years. Make sure to have the correct coolant/water ratio to keep radiator life for years. Good luck.

Mazda 626 is overheating. changed the thermostat twice in 10 weeks Both fans are working;increase temp when Accelerating.tried to bleed air from the system but this model doesn't have a bleed valve.


is coolant circulating in motor/radiator? does radiator top hose get hot when engine has been warmed up? might be water pump, not thermostat. and you do have plenty of antifreeze/coolant in radiator I'm sure.

possibly air trapped on engine side of thermostat-possibly. HOW TO BLEED: loosen coolant temp sensor. Start engine. As engine warms, slightly unscrew sensor to allow air to escape. Once a steady stream of coolant trickles out you're good. Let us know if this helps. Good luck.

Engine overheating i have replaced the radiator has plenty of water


replace thermostat.then bleed coolant system, this is how you do it.fill the cooling coolant system with 50 / 50 dexcool and water to raise boiling point,straight water will evaporate boil away cause engine to overheat catch fire thats why you need 50 / 50 mixture antifreeze and water.to bleed coolant system first fill coolant system until coolant stay at the full cold mark on the the coolant overflow jug,then you start engine allow it to idle,place the heater and ac control in any ac setting except max and the temperature control to the highest setting,run engine until lower hose to water pump is hot. with the engine hot run the engine speed up to 3000 rpm and allow it return to idle, repeat this 5 times. slowly open the bleed valve on the thermostat housing or look for bleed valve at the water pump heater hose.open bleed valve for 15 seconds to expel any trapped air.then top off the coolant as necessary,and when top radiator hose hot thermostat open up.keep adding cooling to overflow until coolant level stop at full cold mark dont over fill coolant.if engine seem like overheating while looking at cooling gauge turn off engine wait a while until cool off add more coolant until coolant level stay stable and dont drop any.when open radiator overflow cap use large rag over the radiator cap to keep from getting scald open radiator cap a little at a time but dont open radiator cap until engine cool down first.replace the radiator overflow cap, thermostat,and engine coolant temperature sensor and check the cooling fans fuses and relays see what happens.

1988 b2200 is overheating--we've changed out the lower radiator hose, thermostat, and the upper hose is fine. Why is it overheating? Radiator, heat pump, or water pump?

Where is the bleed valve located on a 1998 pontiac grand prix 2.8 engine? The auto parts store has never heard of a bleed valve.


Was the thermostat changed? I would suggest replacing the thermostat refill the system with new coolant and purge the air out of the system.

Replaced thermostat but still overheating?


Coolant system have bleed points. There is air in your system that needs to be purged out through the purge valves.. There maybe a few. You have to slightly open them when you first fill the system and let the coolant circulate till a little bit of coolant comes from bleed valves then you close them. Letting the system purge air by leaving the radiator cap open is not enough. Are you sure you put the correct temperature thermostat in , and facing the correct way?

Are you sure that the spring side of the thermostat is toured the engine/ look for a bleeder near the top highest spot in a line or hose that may be able to release the air it may even be near the water pump side.on some water pumps for the ford's the pumps will bolt on and look almost the same but the fins on the impeller are the opposite.clock wise instead of counter clock wise or vice vars. you my wont to check with your parts supply store to see if that is possible.hope this helps give you some ideas.feel free to ask again if you would like any further assistance.thank you for asking fixya .

2005 kia spectra over heating


Did you install a new thermostat and make sure to bleed all the air out of the system when you replaced the radiator? If you didn't, or installed a Stant thermostat, replace it with a FACTORY OEM thermostat. Make sure the cooling system is bled by opening your radiator cap (WHILE THE CAR IS OFF AND COLD), starting the car and running the heater. Add coolant to the radiator as the engine heats up, until is at normal operating temperature AND starts spitting coolant back out.

Hope this helps,
matt

No Heat and Overheating in 1999 Chevy Silverado


After replacing the thermostat, you must bleed the air from the cooling system.

To bleed air from the 2.2L and 2.5L engines, remove the plug or sensor on the top of the thermostat housing. Fill the radiator with coolant until the coolant comes out the hole. Since the plug is made out of steel and the thermostat housing is aluminum, it is a good idea to apply an anti-seizing compound or Teflon® tape on the plug threads prior to installation. Install the plug and continue to fill the radiator. This will vent all trapped air from the engine.

Any trapped air in the heating system will have to be displaced by coolant. Once the cooling system is filled, with the radiator cap off, turn of the heater at it's highest setting. Start the engine and allow it to reach operating temp. You should see a drop in the coolant level as the air in the heating system is displaced by coolant. Add coolant to the proper level and replace the radiator cap.

Keep a close eye on the coolant level for at least the next couple of weeks. The cooling system is a "closed" system. Any significant decrease in coolant level indicates a problem.

If you have any questions, let me know.

Please take the time to rate this solution.

Drive safe and be warm.

The best way to flush it would be to take off the bottom radiator hose and pump water through the fill nozzle after all the coolent is out you can then hook the hose back up and replace it with new coolant.
