Try:

when ur car next overheats unscrew the oil fill cap and look on the inside of the cap, if you see mayonaise then:

you have a blown gasket, hot oil is leaking into the coolant

Is it really overheating or is the GAUGE reading hot. I had the same problem on a 72 Cougar and it turned out to be the sender. If it really is getting hot after all that the check the rad for blockage. Dan

2007 nissan exterra overheats


Hi Kim,

I can feel your frustration. It sounds like you've done all the logical stuff already. The "donut hole" in your process would seem to be not changing the water pump. The water pump as you might imagine, is responsible for circulating (pumping) the relatively cool water in the radiator into the running engine that contains the hot water. Hoses connect the two together. A thermostat is between the radiator and the engine. Once the water in the running engine gets to a certain temperature, the thermostat opens allowing the water pump to send cool water into the engine and hot water out to the radiator to be cooled. The heater core is usually on the passenger side firewall area.

It sounds like the water pump is the only thing left to change - if it isn't working - it can't circulate the water - and will result in overheating. Lastly, a clogged heater core shouldn't cause the engine to overheat - in fact, if the engine begins to overheat, you should turn the heat to HIGH fan and HIGH temperature to help remove some of the heat in the coolant.

Good luck!

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?


!st check and make sure the water is flowing in the radiator, then check
the timeing, Mazda will run hot if the timeing is rong.

I had the same problem with my daughters truck. Changed everything finally changed the radiator, that was it.

The problem is that more heat is entering the water than is being extracted by the radiator.

But there can be a lot of causes for that. If you have a head gasket leak, it can introduce hot gasses into the water, increasing the heat load while raising the pressure in the cooling system. That in turn can push water out of the cooling system, and into the recovery reservoir, where it can't help with the cooling of the engine.

If the fins of the radiator are blocked or folded over, that part of the radiator will not contribute much to the cooling.

If the internal water passages of the radiator are blocked, the area of the radiator is effectively reduced.

A worn out bottom radiator hose can collapse from the suction of the water pump, blocking the water flow.

If the fuel mixture is too lean (not enough fuel in the given volume of air) the engine will generate quite a bit more heat, possibly overwhelming the system.

When the engine is cold, the thermostat (a valve in the hose where water exits the engine to go to the radiator) is closed. This prevents water from going to the radiator, and that in turn prevents water coming from the radiator to the engine.

Water instead leaves the engine through the heater hose near the upper radiator hose, and circulates right back to the inlet of the water pump. So the water circulated through the engine, but it has no way to shed any heat it picks up. This speeds up the warm-up process.

The water circulating this way passes by the back of the thermostat, causing the thermostat to warm up along with the water.

When the thermostat reaches its opening temperature, it starts to open, allowing some water to go out of the upper hose to the radiator, and therefore some water from the radiator to enter the engine.

Right away, the water in the engine falls below the opening temperature of the thermostat and it closes.

The newly cooled water gets warmed by the engine, raising it to the opening temperature of the thermostat, and the whole process begins again. But this time, the water coming from the radiator is just a little warmer.

Eventually, the thermostat will stay at a partially opened position where the cooling by the radiator just matches the necessary heat loss through the radiator.

If there is not enough water, the surface area of the radiator is effectively less.
If the radiator is blocked, or the fan is not working properly, the surface area of the radiator is effectively less.

If the thermostat doesn't open properly, the radiator is not sufficiently utilized.

If too much heat is generated by the engine, it can over heat (heavy load at low speed will make a lot of heat without spinning the water pump fast enough, for instance).

These are a few preliminary tests to see what's going on. With a stone cold engine, start it and let it idle. The heater hose leaving the thermostat area should begin to heat up but not the upper radiator hose.

Once the heater hose starts to become uncomfortably hot, the upper radiator hose should start to warm up, slowly at first.

If the heater hose does not heat up, there might be insufficient flow throw that part of the system.

There is a quick check a shop can perform to see if you have exhaust in the water. There is a syringe they can use to draw the vapor in the radiator through a sensing liquid. If it changes color, you have a head gasket leak.

The radiator cap only need to be replaced if it is letting the coolant move into the reservoir improperly. If you coolant level remains fine, that is probably not a problem.

Ford Escape 2003. Engine suddenly overheat.


Engine over heating can be caused by a number of things. When you say the water pump and radiator appear to be ok I am also guessing that you checked the coolant level to make sure it is normal.

If the level is low then you obviously have a leak. Insufficient coolant circulating will not cool the motor properly because it won't be able to draw enough heat out. If the level is normal then you need to check the thermostat to make sure it is opening properly. To do this, run the motor to temperature and check the top and bottom hoses. They should both be hot and firrm once the thermostat opens meaning the circulation loop is operating properly. If the top is hot and firm and the bottom is cold/soft or collapsed then the thermostat isn't opening.

If the thermostat is operating properly then you ned to look for some other obstruction or cause for coolant loss. Check the head/intake gaskets, hose connections, hoses, over flow tank, radiator fins, radiator side tanks etc..

Good luck.

Over heating, engine only, just had radiator replaced


Thermostat, is where top radiator hose connects / it could be that it is air locked /also could be water pump after removing the thermostat you should be able to see if water pump is circulating. if it was a used radiator ? it could be just as bad as the one you just changed / Have it flow tested .gallons Pier. minutes. also mack sure no kinks in hose./ let us know .Thank You.

My car over heating


Could be water pump propellar going bad, doubt if its the thermostat they either work or dont work. Check your belts make sure they are tight belts could be slipping.
Also clean the front of the radiator this can be done with radiator cleaner you can buy at most any parts store.

Overheating, antifreeze is okay ? thermostat vs water pump


does your have a grining noise? if not its the thermostat.

Overheating.


You mentioned that the cooling system had no pressure when you removed the radiator cap. Somewhere the system is loosing pressure. Have your cooling system pressure tested. Have it pumped up to 20psi and watch for any water coming out somewhere. By the way the lower hose and the upper hose are 2 different temps., this suggests the thermostat could very well be stuck. Take a peek at the under side of the water pump with a flashlight. If you see a trail from the weep hole, there is your problem, a water pump going bad.
