Re: Need AC advice for 2000 Silverado
By 1990 most compressors except 2 cylinder York recip and A6 had dual lip seals (one for vacuum and one for positive pressure) lip seals should not seep oil because oil causes clutch slip modern lip seals have a spiral groove to return tiney amount of seeped oil back into compressor electronic leak ...

Re: 2004 Stratus
My memory is Stratus has a txv with scroll compressor which has a temperature protection switch (TPS) less than 1 pound refrigerant charge is dubious txv systems are typically slow to equalize 1)TPS will cycle compressor clutch with low charge and high side will be abnormally low while low side will...

Re: Odd restriction problem...need another perspective
HI GM Tech Yours is nominated for post of the month! Pretty good advice to look through the resistor mounting opening. Reminds me of the air flow problem in a pick up I fixed. Turns out the dove hunter/owner threw his doves on the passenger floorboard and the dove feathers were sucked into the evapo...

Re: R134 service port leaks
1) New charging valves typically have a light oil film which aids in sealing. When servicing any elastomer in a A/C system, best practice is to apply lube 2) Refrigerant flow through the charging valve washes off all oil from the sealing surfaces 3) OEM charging is into the high side charging valve ...

Re: Opinions: building a Mark IV(?) under dash system
The OEM evaporator was a energy waster because it always draws in approx 30% outside hot humid air for cigar smokers pleasure, therefore a add on underdash evap should be matched with a smaller compressor displacement or lower drive ratio. OEMs never use variable compressors with a standard txv beca...

Re: Mounting evaporator on its side
Among the most compact evaporators are the european OEM rear seat A/Cs mounted under the seat (pugeot) or in the console (VW Jetta early euro version) The Kysor heat/cool coil you refrerence is more than 5" (maybe 8" overall) and is probably less than 6000 BTU for sleeper cab An evaporator...

Lots of changes for Tim and his Band of Brothers
Hope we can recover the picture of the Duke with A/C gage manifold set.
Perhaps Tim will include Duke on the home page if we've lost picture/cartoon ID. I heard the Duke had a cattle ranch in Arizona
