My question is is this enough antifreeze for the heater to blow heat? I will be putting
in 3 gallons of straight anti freeze tomorrow then top it off with distilled water, I hope this
fixes my heat issue. If not then I'm back to square one and still open for suggestions.
make somebodys elses diagnostics easier. Thanks
I just ordered my blend door (previous issue) and followed the HeaterTreater video on You Tube. I will let you all know the outcome of that also.
I have no signs of leakage of coolant anywhere
I have no noise or cavitation fron the pump
I have drained & flushed radiator, both heater cores
T-Stat has been replaced (hard to determine when it opens because engine temp remains below standard, 180 degrees); after a long drive the upper hose & heater hose are hot but not as hot as they should be.
How can I test the water pump efficiency without removing or replacing it?
Thanks, Scott
Thanks for those who replied with some suggestions.

I Have A 2003 Expedition with 139K Miles.
The A/C Works On "Max" Okay But Not As It Did When New.
The A/C Normal Settings Barely Gets Cold.... Just Luke Warm Air.
The A/C And Heat Doesn't Come Out Of The Back system?
What And Where Should I Start To Look?
Andre :confuse:
the front ac only blows hot air and only on highest fan setting.
Apparently we replaced a vacuum hose cause of a check engine light and the ac now blows out the front instead of just the defrost.
but now only hot air comes out. HELP. I live in texas and summer about here.
This is a heater performance problem with a Automatic climate Control LCD panel.
I've read the posts and cannot find anything that seems to fit my problem. First, I have a 99 Explorer Eddie Bower Edition, not many of the Explorers have the Automatic Heater Control Panel with the LCD display, so I have posted to the Expedition forum, as the Expedition has the same automatic control panel.
The symptoms are as follows. The display jumps from 85 to 90 degrees, I'm not sure this is normal, and I never noticed whether this was that way originally because I never had to set the heat setting that high. All of the controls seem to work, air, vent, heat; except for when trying to get heat you will only get it at 84-85, or 90 temp setting. There seems to be a difference in the intensity of the heat at those temp settings, but anything lower is cold air.d. On the 90 degree setting you get cooked. I replaced the Heater Control Valve, because it was easy and relatively inexpensive. When I select different vent options, e.g.: Floor, PNL, Defrost or combinations of, all of those seem to direct the air to the correct vent, but only cool air until you hit the 84-85, 90 temp range. The air conditioning works properly when selected. I've checked the fluid levels and they are correct. My original thought was a leaky vacuum diaphragm in the Heater Control Valve, but as it turns out, the vacuum keeps the valve closed, when the vacuum is released the valve opens, I left the new control valve in. From the forums it doesn't seem like a mixer door problem. My next best guess is the control panel is faulty, or perhaps something has come unhooked. Any thoughts would be appreciated. Thanks, roger@morrisons.ws
I have a 1998 expedition that will not blow hot air out of heater. Have replaced thermostat and didn't help. Is the cool/hot selector switch bad?
Probably the blend door behind the dash board, it is what moves when you select hot or cold. Notorious for breaking.
Thanks again.
That is a vacuum leak, the default in that event is the defrost vents. The usual place for the vacuum lines to break down is where they pass under the battery tray. The clicking in the rear is a broken blend door actuator. There are two back there, one for temp control, one for floor to ceiling.
1: there is air in you coolant system. make sure all of your hoses are sealed properly and no leaks. the system needs to pressurize properly to pump through the heater core. you can change your radiator cap and make sure your overflow line isn't clogged.
2: my biggest problem...the climate control A/C control unit in the dash is malfunctioning. I suggest replacing it, it's only about $40 and saves a huge headache.
3: and last, but not final, check your vaccuum lines! it's very possible you have a broken vaccuum line somewhere on the engine. Fords are natorious for the lines drying out and cracking. I've replaced all my lines with metal (alot of work but well worth it).
my problem was the climate control. it was causing the heater to not blow hot because it was stuck mid-way between hot and cold. wiggling it and nursing it along worked for me until I could replace it. now, HOT air!
hope this helps all
