SOURCE: 2001 expedition heater does not heat well

I would flush the whole system with radiater flush then replace with new coolant. But make sure the heater is set to full heat when you flush it ( while driving around the block with flush in it) so the small radiater that has the hot water flowing through it gets flushed too. It may have some build up in it stopping the full flow of heated water/coolant through. If it is bad enough may need to remove and spray out the rubber hoses from the motor to the heater core, and possibly remove the heater core and hose it out to make it flow better and therefore increase the heating ability. Hope this helps.

SOURCE: 2000 expedition heat problem

first of all I would make sure the car has proper amount of coolant and you are right it is very possible you have an air pocket in the system also ask your self did you change the thermastat after you did the heater core when the car is cold make sure there is coolant at the cold mark on the reservior bottle because you might not have enough coolant then start the car and get it up to temp and if the coolant goes not go up to the hot mark when the car gets to temp you do not have enought coolant just keep adding coolant and you will see the bubble after the thermastat opens

SOURCE: The heater do not work in my 2001 ford expedition

sounds like your thermostat is not working (stuck closed). if the hose on top is soft after several minutes of engine running this is definitely the problem. good luck

SOURCE: 1999 FORD EXPEDITION 2WD 4.6L EGR VALVE,EGR

Remove the throttle body housing on the top of the intake, it is a 90 degree tunnel like small piece held by 4 small bolts, turn it over and look for two holes, these holes are for the EGR valve flow, they are probably plugged up with carboned crud, clean them out with the tip of a screwdriver if neccessary to remove all the crud, once its clean reinstall it and reset your check engine light, hope this helps, let me know

Rear heat not working in 1999 ford expedition. the blend door is operating, is it a good idea to back flush rear heater core ? only one hose getting hot!


It won't hurt to backflush it, but be sure to isolate it from the rest of the system to prevent flushing the blockage somewhere else upstream. Don't be supprised if it won't flush out and you have to replace the core.

My 1999 ford expedition is overheating. Replaced thermastat. Top hose doent get preasure. As im driving starts to over heat then when I turn the heater on gauge goes down then its fine. What can be the...


no pressure in top hose ,where are u losing pressure, the coolant will boil if not under pressure suspect you have a leak or faulty rad cap. some minor leaks dont show until engines warm and are mostly steam leaving little evidence. look for an antifreeze stain or scale deposit around every connection . if electric fanned make sure it works and cuts in before it go,s into the red

I need to replace the heater hoses on a 99 expedition, does the hoses have an especial tool removal?


normally , these are the factory type of hose clamps, you can purchase a pair of hose pliers from a auto part store or try using a pair of channel locks, you will have to squeeze the clip together , then work it back off of the heater hose enough to remove the hose from the heater core tubes. it is a good practice to remove and replace1 at a time, that way , you don't forget the proper location for the hoses.

How do you bypass the water heater on a 97 Ford Expedition?


With long needlw nose pliers the longer heater hose needs to be removed from the heater core by grabbing the clamp squeezing it open and turning the hose till it comes free of the core, Follow the other hose to the place that it hooks to the engine and unhook it there and put the hose that you removed first on the engine. When you get the new core, the hoses will still be good and can be used with the new core. 2) the quick and more expensive way. Stop at an autoparts store and get a hose connecter and two hose clamps. Get out your sharp knife and cut the two hoses where you can get to them, put in the connector and tighten up the clamps. 3) Another way is to get plugs and hose clamps or reuse the old ones and remove the hoses and plug them the engine will cool OK this way too. Don't forget to refill the cooling system and recheck it after driving.

4.6 triton engine expedition put thermastat in still no heat no cold air blowing from defrost but blows on floor only


an expedition has a heater control valve, being from california the heat rarely got turned on so the coolant just sat in the core, expeditions are prone to plugging up heater cores anyway and this would be my guess as to what has happened. the fix would be to remove both hoses from the core and attach a garden hose to the core itself, see if the core will flow water in both directions, if it will, run water in both directions until it runs clear, if not replace the core, also make sure the control valve is not stuck and that the vacuum lines going to it are routed properly, finally.... make sure to completely bleed the cooling system so that there is no air trapped in the system, especially in the heater core
