Tried again today, 100 deg outside & sunny. Ran at 2000 rpm for a bit & LO 13psi, HI 275psi. Cond in 200 deg, drier out 145 deg. Vent temp 65 deg. Started misting condenser with spray bottle & LO 20 psi & HI 250 psi. Condenser temp IN & drier OUT about the same, they didn't drop like I thought they ...

Thanks for the ideas.

Overcast & cloudy today, very little sun heat load. About 7pm, ambient 85 & very humid. When I ran at 2000 rpm & misted condenser it dropped from 225 psi to 200. At that rpm, low was 5-10 psi. Condenser input temp 185 & drier output temp 120 before misting. Vent temp was about ...

Hello,

I bought a 74 F100 with a later model engine using a FS10 compressor, TXV, & parallel flow condenser of original size. The previous owner never tried making AC work. The compressor & condenser & evaporator were on the truck & they dont look new, but they were capped off. I removed ...

i finished rebuikding the system and it seems to be working well. Got in touch with comp mfg and he said although draining all PAG 46 oil out & replacing with 150 would work, he recommended staying with 46. I did that and added the remainder to the other components to get to 9 oz total. I had ...

got the parts and started working. Noticed the new compressor says it has PAG46 in it. But the kit also has an 8oz bottle of PAG150. Should I drain out the 46 and refill with 150?

ok, I'll replace all of those parts and the suction/discharge line as it does have mufflers. I'll flush the evaporator and its lines. I definitely want to do it right and not have to go back into it later so I don't mind spending a little more for a better chance at success.

On the oil, I ...

Finally got back to this car. Recovered and recharged to oem level. No help, still poor cooling. Pulled orifice and it looks like this. Not a good sign, this is going to be entire system as John described?

it has 90K

Hello,
On a 2005 LeSabre it has poor cooling performance. At 80deg ambient, vent temp at 72deg. Low side is 55-60, high side 170. Thought maybe a bit low, put about 10 oz in, low stayed same, high came up to 200, but no better cooling. I'm considering trying just the mechanical control valve ...
