Re: Expansion Valve
Just some backround on my 70-SS Wagon with a Von-Jet carb. Dateline 2004--- Drained and flushed all the R-12. Rebuilt A-6 from Advance ( drain crankcase and fill with 134 oil). Did not mess with POA.
Charged with 134 or 75% of factory 60 oz= 48 oz.
Now A/C kinda works OK.
2007--Screw around with trying to adjust the POA. AT HOME, Drain fill Vac two or three times. A/C still kinda OK.......
2009--Send POA to Classic Air in Tampa,Fla.( 877-342-5526 Ron Mineo or Mike ) POA valve is now set for 134. A/C is getting better. At highway speeds A/C is fine. In the city, Still not up to Par. ( $15.00 shipping & $15.00 to adjust)
2011-- Talked to Ron M. at classic air. They now have a Paralell Flow Condenser for 70s. Paralell Flows are what ALL new 134 car/trks have.
Install new P.Flow Condenser from the Fla. guys, Also new hoses from Hinshaw, For the nice looks. Shot it with argon and test for leaks-A-OK Shot it up with 48 Ozs. of 134. HEY NOW !
Comming home from CB-12 It was 93-94 degrees in Kentucky around noon or one oclock. Started with the blower on " 4 " went to" 3 " then went to " 1 " then I cracked open a wing window.
Befor I left for CB-12 I charged it on a 90 degree day here in Pennsylvania, Wagon was outside in the sun, Black interior, A lot of CU. FT. of space inside......... I was getting 43-44 degrees from the center vent.
Also I have some new rubber bushings for the Condenser mounts, I bought a dozen. Got the info from Tom P.
Note: My expansion Valve and Evaporator have never been off the wagon. Bottom line .. I had the POA set for 134, New Condenser, New hoses ( for looks in 2012), A new dryer came with cond. I bought a Alum. 70 style dryer, Why? You can see it through the grill. Very KOLD air on the highway and in TRAFFIC.
Mech. gauge NEVER hits 200 with the A/C on. I let it sit and idle for around ten min. with the A/C on just to see if it would get hot.
If I can be of any help just ask. Talk to Ron or Mike. They know me very well.
