I reside in Arizona and the temperatures are starting to get into the triple digits. I have read all over the internet that an A/C in a Samurai isn't worth it. Well, I want one regardless. I've done a wee bit of digging online and I've found that most people use the A/C from a Geo Tracker. Is there a website I can either buy an ENTIRE A/C system or in pieces? 1986 Suzuki Samurai 1.3L if that helps narrow it down. Thanks a bunch!

Hit up Mikodaindustries, thats where I got mine. My guess is he will probably have others.

It's not a difficult swap if your fairly handy and have the install sheet. As far as I know they were all dealer installed. Make sure you get the under dash and under hood AC harnesses along with the components. Plan on an aftermarket condensor fan as many of the OEM ones are bunk at this point. I'm using a small universal 10" rad fan. Let me know if/when you want a scan of the AC install manual.

I'm about to charge mine up after I adapt the lines because I have a Sidekick compressor. Dont make the mistake of thinking that 134 will work efficiently in your system at those temps (or any temps really). R12 is still obtainable at a price but I'm running into more folks that use 152 with excellent results, which is what I'm about to try.

They do say that, I have also read that its an acceptable drop in replacement for R12 in secondary loop systems, which the Samy is not. There are benefits to 152 over 134, benefits that could be well reaped by the under-powered Samurai. Also many benefits if your a green person. It takes less to charge and less HP to turn the compressor.

The extremely special circumstances that would have to be present for it to be an issue are like winning powerball. To get hit hard enough to release refrigerant into the cabin would probably already have turned the vehicles occupants into chunky salsa. A fuel fire is plenty more likely than a refrigerant fire.

The alternatives are using 134 and having lackluster A/C performance. 134 is perfect and preferable in a system designed for it so there is no reason NOT to use it there, but for a Suzy it will work but not well by all accounts I know of. I ended up going back to 12 in my truck after a 134 conversion failed to impress when warmer than 85. There are PLENTY of documented cases where 134 failed in R12 systems for various reasons. R12 is a great option if you can find, get and afford it but lofty prices and sketchy availability make that iffy for some.

There is a ton of information and experience out there to read up on, lots of opinions, fact and folks that have been using it for years. I know of people using LP and/or Butane blends without trouble. I opted not to go that route but the 152 looks like a great candidate for this vehicle.

I would encourage doing the research and make an educated decision, I read plenty and talked with those that use it before I made the decision to use 152 instead of 12 this time around. I would not even consider 134 as it would defeat the purpose of staying cool when its >90 deg.

Sorry this is so long but this is a really "hot" subject, especially as July and Aug approach. Whatever you choose please let it be known how it works.

Many years ago I had a Toyota LC FJ40 tin top. The family hated it! Even the family Old English sheep dog jumped our of the side window because of the heat one day.

So I ordered an after market A/C and put it in. It worked okay until it really got hot. The solution was to insulate the cabin. What happens is that an FJ-40and Samurai are bare bones on the inside both of mine were metal tub covered with a thin rubber mat. On a really hot day it doesn't take too long before your motoring around in a giant convection oven.

R12 is definitely better than 134 but you really should work on insulating the cabin of the Sammy. For me, what worked the best on the FJ40 was "closed cell" quality foam insulation. It is very similar to the foam backpackers use to sleep on. Cover it everywhere then a light carpet over that. The tranny tunnel may need extra. It gets extra hot on long highway runs.

My FJ would freeze you out after that!

I'm now thinking of doing an install of an AC on my off road "toad". I have a TBFI 16 valve in a Ca. smogged 87 Samurai. I still have the evaporator and stuff in the cabin, but the 16 v we put in didn't have the ac compressor or mount, pulleys etc. not sure yet what I'm gonna need.

The AC/PS brackets from any other 16v should work, I'm told the 8v ones are the same but not done it personally. The sami compressor will not fit the sidekick brackets and line up correctly so you will have to adapt the lines. This is where I am right now. Or you could modify the brackets and use the Sami compressor.

I have my Sami dynamatted along the floors, firewall, trans tunnel and inside doors and kick panels along with new carpet. I'm planning a partition behind the front seats for temp and noise isolation, and to significantly reduce the volume of air that needs to be cooled/heated.

I'm working out a few details on the lines still but I'm planning a full writeup once its working properly.
