Need some help identifying a part. It appears to be connected to the coolant lines comeing from the heater core. Haynes was no help in figuring it out (no suprise). Its pissing out coolant when my truck warms up. Any idears?

 

Heater Control Valve, sometimes called a Diverter Valve. It it shuts off and bypasses coolant flow from the heater core when the selector is in the OFF or MAX AC position.

Ford OE replacements last about 10 years. Cheapies from AutoZone, etc. often last a year or less before leaking again.

 

Excellent, thanks alot

 

Ive been having problems with my HVAC controls latley. It wants to blow heat no matter where I have it on the temp dial. Could this be a symptom of this valve failing?

 

That sounds like a Blend Door failure.

 

I have 07 Ranger and even when it's on defrost and feet and kicks on the A/C compressor if that's the correct term. Anyone else having this happen?

 

All Rangers in recent memory do that. Try selecting Vent Only, Floor Only or Off to keep the compressor off.
