Have radiator checked for flow . you can remove the radiator cap when cold and start up the truck and look inside radiator. you should be able to see coolant flowing thru the coils. if not you may need to have radiator cleaned by a shop or buy a new one.also check your fan

Temp gauge spikes to hot


Sounds like you have air in the coolant system.. did you bleed the system after you replaced all this?.. did you replace the thermostat? You might add a comment about why you replaced these things .. and how you know they were failing>

Why does my car overheat? The mechanics don't even know...


There are multiple things it could be,thermostat,water pump,radiator,or your belt is loose.Is your coolant disappearing,having to refill,if so then water pump is leaking and needs replacing,if fluid okay,then maybe the thermostat isn't opening properly,but first check belt to see if it is turning tightly.Your radiator may be clogged and needing blowed out.

The coolant is getting hot causing the engine to overheat.


This could have several causes. Is the coolant tank full? Is the coolant relatively fresh and a 50/50 mix of water and antifreeze?
Does the heat gauge jump up to hot and then fall back rapidly at some point or just rise and keep climbing? If so, it is the thermostat. Is there a leak evident under the car? If so, it could be a bad water pump. The water pump has a small weep hole and if there is water at that point the pump needs to be replaced. If none of this is the cause, then it could be a plugged radiator or a faulty cap located on the radiator or the coolant overflow tank.

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.

Engine overheating, no heat to interior.


First off you have no heat most likely because you have no water. Did you bleed all air out of the line once you refilled it. the 3.1 has a bleeder screw to allow all air out. If that was not done you will be driving down the road and you will hit a air bubble that will cause your car to overheat!

Engine problem.


Hi Michael,

The motor shut off and the engine light came on, you won’t start right away and you wait a couple of days and start it again, sounds like your engine was over heated and because it is too hot and the engine frozen.

There are several kinds of engines, water cooling ,oil cooling and air cooling.

Over heated can cause many different problems for the cars, you should check step by step yourself.

Water cooling engine; if you know, you can help somebody.


1. Check the radiator see if you have enough coolant
2. Check the oil see if you have enough oil
3. check the water pump see if the water pump works fine
4. check the thermostat see it is function right.


Suppose your radiator has water or coolant, leave your radiator cap open, start your engine, let it is running 10 to 15 minutes and wait it is getting hot and see the water in your radiator, if the water moves, that means your cooling system works fine, otherwise either the thermostat frozen or the water pump was broken.

You mentioned when you re-start your car, sounds like a diesel engine, please check the where the noise from, if the noise from the water pump area, that means you need to change the water pump. When you change the water pump, change the thermostat at the same time, because when the engine over heated, the thermostat maybe damaged.

Oil cooling engine, check the oil pump. If the noise from the oil pump, you need change it.


Good luck,

Frank
