Boar with bad vision took his last step as he walked right up yo my pickup a few days ago. Dad's 54 chevy had the square Mark IV with a long louver across the top front. Compressor drive belt had to be removed in winter before adaption of a clutch. Temp control by knob on suction pressure regulator ...

Re: Mark IV AC evaporator history questions
pic #1 was popular as a beer cooler when louvers are removed and holes just fit a beer can. Pic #2 established my level of progress in AC development after I went to work for $2.50/hr in 1960 at age 18. Made every drawing on this Monitor and traveled USA to die casters etc. to get tooling. Didn't ow...

Re: 1961 cadillac conversion
SD5H11 LOL You may need to modify OEM blower inlet in AC mode for 100% recirculating air. At 95F/50%RH most OEMs will meet or beat 45F discharge air with 100% recir air but the boggy is only 55F with full outside air. I usually install a shut off water heater valve for summer cooling on vintage OEM ...

Re: 1961 cadillac conversion
Outside the box: 2xo is 75% correct that compressor swept volume displacement can solve your low refrigerant mass flow problem. Suction gas flow restriction is the rest of the story. Relatively small suction hose I.D., bends and choke diameters inside fittings at the compressor should also be includ...
