Head seems low on 98 GMC

System cools ok, but I have seen a decline in vent temps over the past summer. It has the HT6, the suction is around 40 and the head around 180 which seems to low to me, can something happen inside these compressors to where they don't pump correctly? I've recovered the charge, pulled a good vacuum ...

Mr. Bill - this is off topic, but I saw your signature line "Experience is a hard teacher because she gives the test first, the lesson afterwards" -Vernon Law Well, Vernon Law rented a house a few up from my family in 1959 and 1960 on Gilmore Drive in Eastmont (an area east of the Pittsbu...

Re: Stop leak damage, truth or not?

Personally, I would never use any stop leak in any customers system. This becomes the issue, when, not if, you go to change out your system at some point to the new 410A refrigerant, you will have that mess in your copper line-set. A service tech can usually tell if this stuff has been injected into...

Is it me, or does that condenser look either beat up or dirty?

Re: Custom A/C system diagnostic

Hard to beat you listed pressures. IS the capillary tube on the exp valve attached to the suction line and wrapped with moisture resistant tape? I did not even realize it could be a TEV guess my thoughts about changing the orifice can be thrown out the window. :) I have a suburban and it uses a val...

Re: Custom A/C system diagnostic

A smaller orifice should increase the suction pressure, an increased suction will increase coil temperature. If your vent temp is 60° you probably need to increase the orifice tube size "meaning the hole in the tube need to be larger". A lot of things increase vent temps. fan blowing to ha...

Re: Custom A/C system diagnostic

Am I understanding you're using a 71 ford evaporator? I'm not sure that you will ever get that evaporator to work correctly with the newer stuff off the mercury. At this point you're probably going to have to experiment with a few different orifices, probably would not hurt to use an adjustable low ...

Your right, matter fact I called GM many years ago, the answer they gave me was, the valve cap is what keeps it from leaking. :roll:
