Re: hardline and Swagloc fittings for auto a/c

F-150: Maybe you need a #8 hose at the compressor discharge instead of a #6 (you said) Detroit: welcome back to Tim's band of Brothers. You are long time gone but certainly not forgotten. I also spent too many years in 130 degree (military) hot labs and cactus lands and DV (& jim Baker grade) !s...

Re: condinser too hot

20 psi suction proves that discharge valve and scroll tangential gas bypass are ok. Scroll mounted thermal protection switch (TPS) may disengage clutch at low suction/high discharge or air in system Excessive oil just raises louver temp with scroll application Normal scroll wear turns oil gray but d...

Re: AC overhaul pressure problem

Delphi tech The scroll compressor can run liquid slugs all day because of the compliant eccentric with swing link that allows the scrolls to separate which allows tangential leakage with abnormal liquid. Tested 4 times at Lockport with TRS120 scroll on LT and monster condenser which provided 29,000 ...

Re: Liquid line inside suction line?

The suction line heat exchange increases the overall icentropic system efficiency which results in slightly less horsepower per ton of cooling and can reduce liquid refrigerant below ambient for colder louvers Worked on a Rolls Royce with a larger SLHX made by ARA. Rolls was a salesman and Royce a e...

Re: System design with GMA6 Compressor

G'day Mate, FYI: OEM A/C engineers measure "engagement bump" on a dyno with a dial indicator touching the underside of the front bumper. The scroll and external control compressors are first prize for this fully objective evaluation. Vintage Air book "How to Air condition your Hot Rod...
