MY 1st POST CONCERNS ALL WEDGE DRIVERS LOOKING TO REESTABLISH CONTROL OF THE HOT WATER GOING TO & FROM THE HEATER. WE ALL KNOW THAT REPLACEMENT VALVES ARE NONEXISTANT HOWEVER THERE IS HOPE. SEE VOLVO 1977 240/260 SERIES VALVES. NOT FROM VOLVO,<b></b>. NOS $165.00, BUT AUTOZONE $47.00. AZ VALVE IS NEW MFG {SPAIN} ALSO AVAILABLE AT KRAGENS @ A HIGHER PRICE. I JUST PICKED UP MINE THIS AM. NEAR PERFECT COPY OF ORIGINAL VALVE. MFG <b>READY AIRE #5864</b>. I HAVE CONTROL AGAIN!!!!![:)]

Put in a non A/C heater unit and you don't need the valve [:p]

Cliff,
Have you figured out the purpose of the capillary tube? I know it gets clipped onto the AC coil, but I don't quite understand what it is for. Does it modulate the temperature when running the AC?

Beans, I live in a southern California desert. Summer temps reach 110F on a regular basis, 90 miles from Death Valley..Two windows and top down at 70mph is not enough to keep cool, kind of like driving fast in an oven.

Kimmet, the capalliary tube will releas hot water to heater coil warming air going across the evaporator coil to prevent freeze-up inside the evaporator coils..not a good thing, the compressor makes a loud noise when it freezes. Liquid does not compress. Been there done that..It hurt the compressor.[:(]

Don't know how hot 110F is in good old Celsius but Death Valley sounds pretty hot to me [:I]

110F equalls 43.33C for the rest of the world. Hot hot hot. A/C broke down going acrossed the Mohave Desert. That was not fun either. Couldn't drink enough Coke out of the cooler. Temps in the high 90's makes it too hot to drive with top down. We people of the cooler climes tend to laugh at people with A/C in their convertibles but when you experience it you understand it.
