This is my first post here, so please keep the flaming to a minimum.
I've been driving a 1986 Toyota Tercel wagon for 9 years and about 200k miles with no a/c. This is the summer that I'm bringing it back to life. The stock compressor is a 10P13A, and I have a remanufactured one to install. I'll be replacing every component in the system except the hard lines. I realize the stock condenser is the weak link in a 134 conversion; it's a serpentine style that measures just 13" x 13". The radiator and condenser sit mostly side by side (there's a little overlap), and they each have a dedicated fan. The radiator fan is a pusher, and the condenser fan is a puller.
I was considering a 12" x 14" parallel flow condenser, but now I'm thinking of going with something close to full-width. I can do this in the existing space by slightly trimming the brace for the radiator support, and by keeping the condenser short enough to keep it between the tanks on the radiator (they're top and bottom tanks with almost 14" between them). there's no clearance for a puller fan behind the radiator, so I'll either have to cut the shroud on the stock fan or find something else that fits better. Just to plug in a number, let's say I go with the 12" x 27" condenser.
I've been wrenching on cars most of my life, but I've always left a/c work to others. This one will go to the shop to be evacuated and charged after I put it together. My question is how much more effective will the longer condenser be than a 12" x 14", and am I thinking in the right direction?
If I remember correctly we did a conversion like your mentioning. Tossed the small T & F condenser and installed a PF which ran both in front of the radiator and the gap where the old T & F sat. Added a puller fan to that section and it worked OK. That was years ago and was a custom job but turned out much better compared to the small condenser with R12!
Thanks for the info. I've been looking at the stock fan setup, and I believe I can make the radiator fan work with the new setup. The condenser fan is easy, it won't take any modifying at all.
My next question is; How can I set up the stock radiator fan to work with either the a/c or the radiator temp sensor, since it's currently only a single purpose fan? I assume I'll need to build some sort of relay harness, but I'm a mechanic, not an electrician.
Fan, relay and wiring harness is all that is needed. You can trip the relay either by wiring into the a/c on circuit or the clutch circuit. You must use a relay or you will trash you clutch with feedback. We can set you up with all these items if interested.
