It started out one day at the car wash in the automatic one. I turned off the expedition and let the wash do its work. after it was done i went to turn on the expedition but it didnt even crank so i had to push it out. once i had it outside i tryed again and it finally cranked then a few more times it turned on. i let it sit because it wasnt idling normal. i let it sit over night, next day i came back and it was aright. then after awhile (i don't really remember how long after) my heat stopped working. then again after awhile (dont rememebr how long after) the expedition started to overheat. after like 2 times of having to buy many anti-freeze liquid i realized it was an ongoing thing. so i just parked it and havn't moved it since then. the battery is dead now but after winter passes i'm going to try and get it fixed but im not sure whether its the thermostat, heater core, water pump, radiator, fan, etc... SOMEONE PLEASE HELP!
The problem possibly could be due to a hole in the coolant system, i.e. a hole in a radiator hose or even the radiator. Loss of coolant will cause the heater to stop working and the engine to overheat. If it runs normally for a time, such as several days or a few weeks, and only after that time has passed the heater stops working and the engine starts overheating, then suspect a leak someplace. If it starts overheating after driving 5 to 10 minutes regardless of how recently antifreeze was added then, possibly the thermostat. It is staying stuck shut and preventing the hot coolant from leaving the engine and cooling in the radiator. The radiator overflow will probably have antifreeze pushing out the cover as a clue. However this can also be the result of a blown head gasket. As far as the fan, does the vehicle have an electric fan or is it driven directly by the drive belt. If it's electric, then warm it up to operating temp and open the hood and listen if the fan runs or not. It will start and stop depending on how warm the engine antifreeze is. If it does run, then the fan is fine, if not then the temp sensor that activates it is not working and needs to be replaced, or the plug into the fan may have become disconnected. If it's driven by the drive belt, then it should not be an issue unless the belt is broken, which would probably be affecting the power steering and alternator as well. If the vehicle has no power steering and the alternator light is on when running and it overheats, check to see if the drive belt is broken/missing. Check also to see if the water pump pulley is wobbly or loose. That would indicate a bad pump and would need to be replaced. Hopefully you just have a hole in a hose, and a simple hose replacement will fix it. incidentally, it's a good idea to replace both upper and lower radiator hoses at the same time, and the upper radiator hose is usually attached to the thermostat housing, so replace the thermostat at the same time too. Good luck.

water pump ,its a plastic impeller and its loose on the shaft ,,,,,had one a while ago exactly the same but the first time i came across this on a saab i done the same as you ,changed everything ,felt a right you know what

Check voltage at fan motor, sounds like fan motor has had it, that's why it was spinning slow, kinds like a starter, won't work as fast when starting to go out or not work at all, if you have voltage, replace it.

Easiest solution is air trapped in the cooling system. Make sure you have bled all the air out of it. If it has been properly bled then it might be your head gasket or a crack in the head itself.

Follow your glowplug wires towards the Firewall. The glowplug wire goes into a Timer which is suppose to be internally regulated by outside Temperature and feedback from the glowplugs.
When you are in Cold weather, the Timer is suppose to keep the glowplugs on longer. When the engine is fully warm and you shut it off, you will notice it starts up like a gas engine. First you want to remove your glowplugs and check them by using Jumper cables and heating them up.
Be careful because they can melt or distort if on too long. I usually pull out 4 at a time because it is a comparison test and when you find the quickest, brightest glowplug you measure the others against it. When the glowplug stays dark or does not heat as quickly it is bad. Remember when it is in the engine the glowplug only has bumps of current coming from the Timer to warm up.
Once you are confident the glowplugs are okay, try starting the truck. Or for good measure, just change the Timer, but it will add to the cost.
As for the engine light, if you mean the "check engine" light, you can get that checked free at Autozone, Oreillys, or Advance. I believe Advance may be better equipped to test the PCM.
I hope my solutions are very helpful to you and thanks for using this service.
Testimonial: "Thanks for the fast response. I'll let you know the results of my testing as soon as possible. For your information the truck has only about 70,000 km"
