Question about 1999 Ford Expedition

1 Answer

There isnt coolant going through the heater core, therefore no heat. Is there a valve or could the core be blocked with something? It's a 99 Expedition Eddie Bauer.

    Are the hoses going in and out of the core getting hot? if only one side is hot the core is blocked, if this is the case, is the cooling system rusted or otherwise contaminated??

Yes very common you will have to flush it out using a garden hose with good water pressure. disconnect both hoses connect one to the hose and turn the water on keep switching to back flush it until clean water runs out of it. reconnect hoses and it will be fine.

My 99 GMC sonoma with a 2.2L is not warming up properly


Possibly plugged or inerporable heater core. Possibly heater core valve (this diverts hot air through your heater system) When you flushed the block, was there a lot of contaminant? 95% of the time, cold heat means thermostat. Also there are a lot of really cheap after market thermostats, you can buy one as low as $6.00. That being said, just because a thermo is new doesn't necessarily mean it opens/shuts when it should. You can look on You Tube on how to test one in your kitchen with boiling water,.

So three basic things affect interior heat temps. Thermostat, plugged heater core/.valve, and insufficient coolant or liquid to tranfser heat. If your interior coolant (engine temp) is working normally and your vehicle reaches operating tempature according to the needle, your thermosat is probably not the cause.

My bet is somehow, your heater core is plugged so that their is not enough "flow"

Will my coolant not circulate if my heater core is out? If my heater doesnt work does that mean the heater core is out?


change out your thermostat, heater core will leak inside of car if damaged and another thing the water pump is what circulates the coolant thru out engine

The heat in our 1998 continetal doesn't work. We replaced our thermostat. Still on heat. The a/c works fine. The vehicle run fine without any sign of over heating. We can't undrestand why the car's heating...


Two possible reasons, one is that your heat control valve that directs hot coolant to the heater core may be stuck or blocked. Two, you may have an airlock in the heater core that prevents water getting in to the heater core. You need to let the air out by loosening the upper most hose that feeds the heater core.

Vw golf 2001. coolant system not working


Your most probable cause for this is because your water valve needs replacement or repairing. Not all cars have a water valve that brings the heated coolant into the heater core unit.

Essentially, the heated coolant is brought from the engine block directly, into a mini radiator that has a fan to blow heated air into your vehicles cabin.

If that valve were clogged, or the switch itself to open up the water valve that blocks the coolant from going into the heater core unit, then you wont be able to get heat from the vents.

ALSO, another reason why your car might also be overheating as well, is you need to check your coolant levels as well to make sure it is fully filled up, if it is, then your thermostat might also need replacement.

good luck with your problem.

I am not getting any heat from my heater when turned on just cold air


Check operation of the heater core coolant control valve and associated remote control mechanism.
Chech heater coolant hoses are not kinked or crushed,
Check that both inlet and return heater hose is equally warm, as this indicates coolant flow through the heater core.
If no coolant flow:-
Check cooling system is correctly filled, taking care to bleed off any air locks from the system as necessary (with heater coolant valve open);
Check heater core is not blocked- if blocked you may be able to backflush.

My heat not workini but blow cold air where is


Has the car been changed coolant since it was bought? If it is time to change, let do a flush through a heater core. There are 2 coolant hoses going thru a fire wall. One for coolant in and one for coolant out. Heater only works if coolant is flowing through the heater core. Therefore, there are one or both following cases contributes to the problem: 1-If the valve control coolant flow gets stuck, then it always closes  so there is no heat. 2-If the valve is working, but the heater core gets clogged up, then there is no heat.

No heat


This sounds like one of two things, either there is not enough coolant in the system, or the heater control system is messed up. try this, with your car running at about 205 degrees (feel the upper radiator hose, it should be hot to the touch) grab both of the hoses going into the heater core behind the engine, the should be warm to hot. if they're not warm at all, or just luke warm, you either don't have enough coolant, or the hoses are blocked somewhere. if there is a valve in line with one of the hoses, try to operate it by hand, sometimes those valves (called heater valves) fail.

if the coolant is full and there is hot coolant in both hoses going into the heater core, then you're controls inside are likely the problem. try to turn the heat control from cold to hot and back again a few times, you should be able to hear a clapping sound,it might be very faint, so listen carefully. if you can't hear anything, it's likely the controls itself, unless you hear a hissing sound from behind the dash when you turn the control, that would be a vaccuum line unhooked. you'll have to pull some panels under the dash to find this vaccuum line to hook it up, but it's not too hard , just takes patience. (it's more common for a heater control to go first)
