Adding AC to a 1980 pickup 20R, looking for the mounting brackets an clear images to help guide me in the right direction. I’ve called all Toyota yards and no luck. Please let me know if you can point me in the right direction.
thanks for any help your can offer.
happy healthy holidays

Did you buy that one on ebay?

 

I did find brackets after calling every yard in the US and Canada. Re: eBay I check it offer and you most likely will NOT see a 1979 or 80 AC brackets. They are very rare based on my experience. Got lots of other parts on eBay :-)
cheers

 

I had one on my watchlist for months and someone just bought it.. i should have pulled the trigger on it. Actually it might have been a PS brqcket, nvm
Keep me updated on the conversion. Are you gonna do r134a?

 

I added AC to my '81 and had to make my own mounting bracket. I used paper and pencil to rub an outline the hole pattern on the engine. Cut and drilled some 1/4" aluminum plate. Then made 2 standoff brackets and attached to compressor with the bottom trough bolt, aligned the compressor v-belt pulley on the crankshaft and marked their location on the plate. Welded on the standoffs and made an adjustment arm.

This what the finished bracket looks like. Hope that will help.

Thanks for that note and image. I actually did find a bracket but many people I know will love the image and knowledge of making their own. I live in the LA area around Encinio and looking for a mechanic help me put everything together… I have everything I need just not sure I have the confidence to put it all together and the AC fluid… charging. deananux@gmail.com. I’m not sure the forum etiquette for leaving my email. Love to pick your brain on what all you’ve done.

 

You can go to my build thread, page 5. to get an idea of what I've done so far concerning my A/C install. My build has stopped temporarily due to health problems. .https://www.yotatech.com/forums/f197...ghlight=lons81 If you have questions, just fire away.

 

Do you have all the parts and lines you need?

If you can assemble everything, any shop should be able to charge the system for you. And if you can put the components in place, you can find a hydraulic shop to make any hoses you need to connect everything.
Im not sure what level of mechanical aptitude youre at, but you can do the whole process yourself if you have the time. All you need is a set of gauges and hoses from Harbor Freight and an hour on youtube.
but, theres also no shame in taking it to a shop if you can afford it. You can call around to any shop that advertises AC work or any shop youve had good experiences with should also be able to do the job. The hard part about taking it to a shop is they might not want to have you do half the job then have them finish it

 

All good points. I can probably do it, I guess I was hesitating for some reason. Just didn’t want to mess anything up. I haven’t t seen a good of YouTube videos on installing AC. I shall look deeper.
I hope your health improves, thanks again for your two cents. I means a lot.

 

So after a closer look, It looks like I need to remove the fuel pump, Install electric fuel pump, I need a block off plate from where the old fuel pump was. I have both, just not sure about wiring the electric fuel pump. I do however need to buy an dryer, overlooked that.
and I need an dash switch to turn on the system… and does that entail some extra wiring harness? I’d like to do it myself but as the list grows my confidence shrinks.
thanks again for any encouragement

I bought all my stuff from Old Air Products in Ft Worth. But there are other vendors for all the parts. Why do you have to replace your fuel pump? I added the A/C bracket in place of the smog air pump, and made it not to fit under the RH motor mount. Just try to mock up something with cardboard first and it will an idea what you can do

 

Living in Los Angeles I’m not sure I can remove the smog pump because I need to get it smog test every two years. I’ve checked out all of your last post over the last 10 years wow you’ve done an amazing job. Thanks for your service by the way. I shall take your advice and make a cardboard template and see what it looks like. As removing the fuel pump that’s just what everybody told me I needed to do for the 20R motor. Not a lot of people share their knowledge in images of the 20R motor. It seems like a unicorn in this community.

 

 

Awesome looking truck. You'll need to download the 83 Toyota Truck FSM up in the Stickies above, this will give an idea of what parts you'll need to install an A/C system. From what I can find, you don't need to remove the stock fuel pump as the compressor sits above the smog pump with the required clearance

 

Download and learning a lot and now know what I need. Good suggestion. Thank you.
I need to wrap my head around what I have
and how to proceed.

 

Next time I'm down where our '80 lives I'll try and take some photos. Sorry I don't have them handy at the moment. The truck is down in Fallbrook but I'm in OC. Our truck has factory air and the mechanical fuel pump is right where it's been since day one. We are the original owners and so I know the truck has never been molested. Sadly it's not in as nice shape as yours. haha. I don't see why you would need to remove the FP??

 

Thanks for the response. I’ve looked at a few images online of the 20R engine and most have the original fuel pump, this is good news. Just found and bought an AC wiring harness yesterday. It would be good to seem more images so I can confirm all the little details.
I think it needs a carburetor judgment, it never ends with these old trucks but I enjoy every minute of it. At least the engine is quite simple compared to most these days.

 

I'm planning a trip down to check on my mom(where the truck is) this weekend, so I'll grab some pics. Any specific detail you need? Is your truck a CA delivered truck? If so the 20R is simple, sadly the vacuum line/operated smog system is a nightmare. Are you still running the stock Asin CA version carb? BTW are the stripes original or the reproductions? https://jamesdeancreations.com/1979-80.htm

 

Yes, As far as I know it’s a California delivered truck and yes it is original carburetors far as I know. I guess it would be nice to see several angles of how the AC compressor is mounted to the engine and relates to everything else around it. That would be great thx. Thanks for the James Dean graphics link - he’s who did these:-)

 

I got down to the truck yesterday and managed some photos. Hope they help. Hard to really see the bracket with everything installed. https://photos.app.goo.gl/zcmzb8hZtZUKnoqq6
