SOURCE: Where is the heater core hose in my 2000 ford expedition?

check closer to just underneath the firewall--it could be a smaller problem than a heater core--Ford 4.6--5.4 engines have a tube just underneath the intake manifold that the rubber hose goes bad and it will leak towards the back of the engine.Lets hope so-what i hear its very expensive to change a heater core in an Expedition.

SOURCE: i have a 2000 ford expedition and the heater blows

Check the vacuum hoses from the switch to the engine compartment. If you manually operate the heater valve on the firewall (follow the 5/8" hose) you will get heat.

I have a 2001 ford expedition my ac works just fine but the heater does not work at all. Any suggestions?


Could be a couple of things. Newer vehicles have a heater control valve inline with the hoses that lead to the heater core. Another thing to check would be your coolant level. If it is low air can become trapped in the line and restrict flow to the heater core. Be careful when checking your coolant level it is a pressurized system.

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

Can not find heater control valve 2000 expedition


what year? for 2000, there are no control valves. It mixes a/c air with heater core air to blend the right temp.

SECTION 412-02: Heating and Ventilation 2000 Expedition/Navigator Workshop Manual
DESCRIPTION AND OPERATION Heating/Defrosting The heating and defrosting system has the following features:
  • Controls the temperature and, during A/C operation, reduces the relative humidity of the air inside the vehicle.
  • Delivers heated or cooled air to maintain the vehicle interior temperature and comfort level.
  • Controls the A/C blower motor speed.
  • Cooling or heating can be adjusted to maintain the desired temperature.
  • Uses a reheat method to provide conditioned air to the passenger compartment.
  • The blower motor draws outside air through the A/C recirculating air duct, except for MAX A/C cooling, when recirculated air is used.
  • All airflow from the blower motor passes through the A/C evaporator core.
  • The temperature is then regulated by reheating a portion of the air and blending it with the remaining cool air to the desired temperature.
  • The temperature blending is controlled by the temperature blend door, which regulates the amount of air that flows through and around the heater core, where it is then mixed and distributed.

I cant locate my heater control valve, where is it???


The heater flow can be checked by feeling the hoses at the inlet and outlet to the heater core. If the heater has a control valve and it is open, both hoses should be warm. This indicates that coolant is flowing through the heater core. If the outlet hose is cold, there must be an obstruction in the heater core or control valve.
