    we replaced the water pump, thermostat, radiator cap,and fan relay.
    Nothing helps. Everything works fine for awhile then the pressure builds up in the cooling system and blows all the coolant out and the pressure destroys the radiator. We are now on our fourth new radiator!
    Please help.

If the head and gasket are good, and hoses not blocked, and the coolant pump is good and the rad is not blocked, all sensors and thermostats good, then it could be the heater core.

If you can bypass this during summer, it may help. The heater core is like a very small radiator, and often they get blocked up. This can restrict the collant getting around the engine properly, and cause overheating. If you leave this bypassed, you won't get hot air blowing into your cab during winter with the heater on --------- hey, who cares right now when it's summer!

2000 FORD EXPEDITION OVERHEATING....changed thermostat,radiator cap, confirmed fan clutch is working, no radiator leak noted, changing coolant temperature sensor as a type...water pump not leaking or...


yes. the impellor on these engines have a tendency to come off the water pump.First you can see if the pump is working by removing a heater hose then have someone to start the engine. if the water sprays a good, solid stream out then the water pump is good. if the water just barely comes out or not at all then the pump is weak or "bad".

Ok, g35 coupe 06,52k miles Had over heating problem in april 2010,replaced thermostat, all's well. Now Jan 2011 overheating again, noticed upper & lower radiator hoses collapse, changed thermostat...


Heres a couple of things you can check. Start your car and remove the radiator cap,(before it gets hot mind you) when it reaches norm operating temp, look inside radiator to see if water is circulating. If its not moving, its a bad water pump. Also, youre hoses should never collapse, if they collapse when they get hot maybe you need new hoses? Finally, if those dont work, flush out your radiator. Open the bottom cockpit and use a garden hose and let it flush out the system while the car is running, about 10 mins should do the trick. If the radiator looks clean inside then it doesnt need flushed.

My van is overheating. The coolant is full. The heater won't get warm. The fan is working.


Check your thermostat to see if it is sticking. You may need to replace it. It is located within the large hose coming from the radiator and at the engine where the bolts attach.

It overheated, smoking and water pouring


If water poured out you probably busted a hose or radiator sprung a leak. Sounds like that and a bad thermostat or water pump went out.

My car is overheating. I just replaced thermostat and recently replaced the water pump. I checked for water leaking but dont see any. What could it possibly be


If the thermostat and pump have been replaced, it's most likely the radiator. They corrode after time. Try flushing the antifreeze (not just draining and refilling it, but flush the system with clear water.) Most auto stores, Walmart, etc. carry the flush kit for very little $$. Once it's flushed, refill the system with the correct ratio of antifreeze.

If the problem persists, then it's most likely gunk in the radiator. Auto shops can boil them clean.

Short of all of the above, overheating can also be caused by a cracked cylinder head. If it overheated too bad at any point, it can crack the head and will continue to overheat regularly. Check for antifreeze in the oil. If there "is" antifreeze or water in the oil, the head is most likely shot (and yes, it will still run that way).

The water on my car keeps heating up alot and it goes into the engine coolant resevoir leaving the rediator dry


You need to replace the radiator pressure cap. I would also replace thermostat, drain and flush radiator to start. If it continues the water pump may be not pumping water. If the thermostat is stuck closed it wont allow water to cycle through the engine causing it to boil and the pressure cap is not holding the pressure allowing it to flow to the reservoir. So first change the thermostat and the radiator pressure cap.

RADIATOR.


remove radiator and power wash fins they could be blocked then install again then get a good engine flush drain water then refill with flush and water then start and drive read the flush bottle for instructions then let all out again then refil with clean water and a good coolant , remember to blead the system when filling every time you drain water etc, hope this helps. it will work.

Keep overheating ,wont hold water in radiator


If it overheats very quickly, it likely has a bad thermostat. If the radiator does not fill easily when re-filling, likely the radiator is internally blocked and requires either a flush, boil out or replacement. Make sure any electric fans are properly operating. If you have any white smoke or coolant in engine oil, you may have a blown head gasket. A shop can identify this condition by checking for hydrocarbons in the cooling system, or by doing a compression or leakdown test.Do the easy stuff first...change the thermostat. If problem continues, go further with your diagnostics.
