2000 windstar is leaking coolant behind motor and smells with ac on...Heater core?


Yes u have a leaking heater core, below fin d the instructions to replace it.
1997-2000 Ford Windstar 3.8
Heater Core
Inspect ' Replace
Drain the cooling system

Heater Housing

The heater housing is usually under the dash and must be removed to gain access to the heater core. Procedures for replacing the heater core vary with the year, make, and model of car. It is therefore necessary to consult the manufacturer's repair manuals for the proper procedure for replacement.
The heater housing is disassembled to get to the heater core.
Heater Core Remove the access panels(s) or the split heater/air conditioning case to gain access to the heater core. Remove the heater coolant hoses. Remove the cable and/or vacuum control lines (if equipped). Remove the heater core securing brackets and/or clamps. Lift the core from the case. Do not use force. Take care not to damage the fins of the heater core when removing. To reinstall the heater core, reverse the removal steps. When the heater core leaks and must be repaired or replaced, it is a very difficult and time-consuming job primarily because of the core's location deep within the firewall of the car. For this reason always leak test a replacement heater core before installation.

Can a sweet smelling heater be a water pump problem or only a heater core leak


I could be either one,but if you smell antifreeze, than you should be able to see a leak while the engine is at running temp. Fell the floor for wetness for heater core, Check under the hood for wetness for hose or radiator. Also, if your windshield fogs up, it is most likely the heater core. You can also pressure test the cooling system to verify where the leak is.

Why does heater smell sweet


Hi yu heater smelling sweet is not a good thing. There is an engine coolant leak probably in the heater core and the smell your noticing is aspirated ainti-freeze. Check your engine coolant. It should be slowly lowering. The only fix is to have the heater core replaced. You can for the moment bypass the heater core by looing the hoses together with a nipple on the engine side of the firewall but you will have no heat or heated defrosting abilities until you replace the heater core.

Thanks for choosing FixYa.

What kind of battery is recomended fora Ford Winstar 1999 in terms of durability and capacity to feed the alternator properly?


There are two different engines Ford installed in the Windstar. The following information is assuming your vehicle has the 3.8 liter v-6...850 cold cranking amps, 750 cold cranking amps, 650 cold cranking amps, or 720 cold cranking amps. It is highly probable that your vehicle has the 3.8 liter, as 94% of Windstars had that engine installed. Hope this helps you out.

My 1999 ford windstar is only blowing cold air and no heat


possable problems:

1. coolant leak (level too low to fill heater core)
2. headgasket leak forcing the coolant out of the overflow.
3. stuck thermostat.
4. bad water pump. if the impelers are broken, coolant wont flow.
5. HVAC malfunction. system may think you selected cold or is unable to move diverter. maybe a fuse,solenoid or vaccum leak? (hvac controler uses vaccume controled soleniods)
6. airlock. if you have resently changed your coolant, you may need to repeatedly squeeze the heater core hose to help force out the air.

1999 ford windstar heater lever will not turn on front heat


Check on the heater control valve. It is probably close to the firewall behind the engine. There will be coolant lines attached to it. This valve should have an arm on it that opens and closes a valve inside, either shutting off or allowing hot coolant to flow into the heater core. The arm should be attached to a cable coming from inside the car. See if the arm moves when you move the heat temperature level inside the car.

My heat doesn't work in the front on my 1999 ford windstar


You will have to service your cooling system including the heater core which supplies heat to the cabin. Also, if you have not had your thermostat replaced, now is a good time to do it before it malfunctions.
A heater core replacement may be needed.
