Reply to "4 row condensor vs. stock 3 row"

Definitions: the Pantera's condenser is in the rear while the evaporator is under the dash, just so we are talking of the same parts. OK; remember, the interior volume of a 2-seat car is quite small, similar to a mini-pickup truck, so increasing the size of the cooling components IMHO is like bandaging a bleeding bullet hole- it addresses the symptom, not the problem. The Pantera's components are OK (for the'70s); the arrangement is unusual. The only real design issue is the excessive length of the lines, and the fact that they are all rubber, promoting leaks. A leaky $30,000 system won't keep one cool. To have an operating system in your car, use the absolute best lines you can find such as barrier hoses with o-ring end connectors.Second, a positive shut-off of the hot water running thru the heate core (the stock valve cannot shut off water AND open fully). Third, be sure the tiny "secret" filter in the under-dash valve is clear of 30 yrs of debris. And finally, move enough air through the AC condenser core to heat-exchange the freon. The rotary compressor is lighter, more efficient and vibrates less than a rotary, but there are may cars out there with fresh lines, tight connections, full loads of freon and old Yorks, that pump 34-degree air. Oh, yes- forgot: according to the mfgr (Aeroquip) braided-stainess teflon hose is porous to R-12 & not recommended.
