Vintage Air questions
Greetings,
I installed a vintage air system in my 69 C-10 non air truck. I took it to a local shop to have it charged. The instructions said the system took 1.8 lbs. We installed about 1.5 lbs, the high side psi was about 300, and the low side was between 35 and 40. The mechanic said I needed a higher velocity water pump fan. I bought the fan/clutch from LMC, installed it, and went back to the shop. No change. I explained to the mechanic (??), the instruction said to set the rpms to 1500, and place a whoop ass fan in front of the condenser. The mechanic (??), said he's been doing this for 20 years, that is BS, there is something wrong with the system. I called vintage air. They said it is fine, we have too much coolant in it. It should have 240 to 250 lbs on the high side, and 25 on the low, at 1500 rpms, with a whoop ass fan on the condenser. Went back to the shop, we did set it at 1500 rpm, placed a fan (they did not have a whoop ass fan) on the condenser, pulled the coolant out, and installed 1.25 lbs, then added about .10 more lbs to get 250 psi on the high side. We could only get 20 psi on the low. The mechanic (??), said the fan/clutch I bought isn't working right, WTF??? I may go buy a gauge set, borrow a whoop ass fan from the fire department, and do it myself. Before I do that and/or call vintage air back, I was wondering what experiences and/or tips others may have???? I was an electronics technician for 35 years for a pipeline company, and dealt with a lot hammer head mechanics, but I was paid to do it. I don't like paying to deal with them now. I'd just like for it to work before summer is over. Thanks for all replies. Phil |
