In August 2002, I developed a pinhole in the center of the evaporator on my 1988 Mazda B2200, confirmed that with soap bubbles. With 2 kids and money tighter back then, I bought a new serpentine-type copper and brass evaporator, drove to Arizona Mobile Air on W. Clarendon as it was in-stock and less than half the price of the replacement evaporator if I ordered through Mazda, and Arizona summers are hot. My 11-year old daughter helped me install that next day.

Question for Tim (and others): would that serpentine-type copper and brass evaporator be less efficient than the aluminum "plate" style Mazda evaporator, or pretty much the same? I'm still on R-12 and have a leak free system, and I would NOT be replacing the existing decent evaporator just to get a couple of minutes earlier cooling, I was just wondering. Thanks.

And only 115F today and tomorrow in Phoenix, AZ for those wondering.....

I've always linked the P & F Design.

Those aluminum evaporator cores are just fine. I would definitely not tear apart a working system to swap out one of those.

My own practice, with more than AC: "Never trouble trouble until trouble troubles you"

I tell folks that if their AC and heat keep you comfortable, then there is no need for a "check up". Change a cabin filter, clean off the condenser surface, and take a look-see at the compressor belt if you feel you want to "do something".

I totally agree with you. Leave it alone.
