What does a heater valve do?
The heater control valve regulates, by opening or closing, the amount of hot water that enters the heater coil.
Why restore or replace your heater valve?
A good indication that your heater control valve is failing is if your air conditioning is functioning correctly and your system gauge readings are correct, but you’re getting heat or warm air out of the vents. This could be as a result of a failed heater control valve that will not shut off the flow of water to your heater coil. The heater control valve can also fail by leaking, or even by not opening and allowing water to flow into the heater coil in heat-mode.

Classic Auto Air carries new heater control valves, we have thousands of NOS & NORS. While we do have some of the most common heater coils, many are no longer available. In most cases, Classic Auto Air can re-core your original or we may have a NOS coil available. Please call or email for more information.
We offer many NOS & NORS heater control valves for Ford vehicles and also restoration services for most lever-operated heater control valves. Call or email for more information!
What is an expansion valve?
The expansion valve is mounted at the evaporator inlet and regulates the refrigerant going into the evaporator.

Why replace or restore my expansion valve?
Most a/c technicians will automatically change out the expansion valve as it’s commonly a source of air conditioning failure. A good indication that your expansion valve has failed or is failing is a negative or high system gauge reading. This is either as a result of contaminants clogging the valve up or valve failure.
Because many valves are no longer made, Classic Auto Air offers testing and reconditioning services for your original. There is also a good chance that a NOS or NORS might be available. Please call or email!
Expansion valve reconditioning consists of:
- Flush clean internally
- Clean externally
- Re-plate, if originally plated.
(POA, By-Pass, Suction-Throttle)
What is a suction valve?
The suction valve (aka Suction Throttle, By-Pass or POA Valve) is found on some late 60’s & through early70’s Fords. It is mounted to the evaporator’s suction (top) outlet and regulates system pressures so as to prevent the evaporator from freezing up.
Why restore my suction valve?
A good indication that your suction valve has failed or is failing is a high low-side system gauge reading. This is either as a result of contaminants locking the valve or clogging the valve up or valve failure. If you’re converting to 134a, your valve will need to be properly calibrated as by-pass pressures differ from that of R12. More on Converting to 134a!
