Hello
I have 1978 Toyota Chinook all original with a rebuilt original carb. I want to install an AC. I need to know if this carb for the 20r was setup for an AC kit to receive the vac lines and/or a solenoid?
I need to know what all the parts i should look for and what to look out for in terms of bad parts.
if i can't find 1978 parts what years and parts can i use?


i snagged this from another post somewhere down the line:
AC compressor(and brackets)
3rd front pulley ?
Underdash AC unit (don't forget all hardware)
AC Amplifier (Under the dash...like an AC computer)
AC compressor On/Off button from the dash
Idle kickup solenoid/valve (On top of the motor... easy to miss)
condensor, lines, evaporator

anything else i need or dont' need from this list?
any hints or warnings?
thx
john

 

I have a 1978 pickup with AC. The under dash AC unit has all of the switches, it's just an on/off and fan speed deal, no climate control or anything like that. The AC compressor hooks up above the smog pump and a longer belt is used with the smog pump as a tensioner. If I were you, I would try to source a junk truck with AC and pull all of the parts out. Finding each individual part is going to be tough. I'm pretty sure all of these trucks were set up to be compatible with AC as an option

 

or you could buy a brand new AC kit from vintage air for around $800. Summit racing has a few kits also.

Thx for the advice. I'd love to find the fsm install instructions and have them posted on the forum.

 

I have a 77 chinook with ac that I'd be thinking about selling the entire rig if you're interested
