Fixed the A/C in the ol 79 K10

[2018GMC]

Decided to fix the A/C in my 1979 K10.

 

Cost me less than $500 to get it fixed.

 

I bought the following parts new and installed myself. Saved some $$$ at Rockauto

 

Evaporator

Accumulator

Main A/C Hose from compressor to Accumulator

Hose from condenser to accumulator - could only find at LMC

O-ring kit

Belt

just under $300

 

Took to local mechanic to have system evacuated and flushed.

System held a vacuum

Converted from R12 to R134A

Charged with R134A

$200

 

Just wanted to let people know it's not crazy expensive if you do most of the work yourself, then have it professionally charged.

Only issue is 400 rpm idle in drive with A/C on due to my Edelbrock 1406 650 com carb not having the idle selonid to slightly increase throttle when A/C is on. $155 !!!

Did you keep the stock condenser or upgrade?

[2018GMC]

Kept stock condenser.

I guess there is newer design? It was 85 today and A/C was ice cold on highway. It would warm a bit when stopped at a light but through town it seemed to cool fine.

The original condenser isn't efficient enough to shed heat using 134a. That's why most conversion include the condenser

Thanks!

 

I thought about selling it awhile back but couldn't do it :-) A few years back you would see this body style all over the road but now The few I see are hammered ones or 8 - 10 in lift with cut fenders.

 

I will get mine repainted some day but then I won't want to take it off road lol.

 

A/C wasn't expensive to fix if you replace most parts yourself from Rockauto, Online, Etc.

 

I should have fixed it 10 years ago lol. Nice having it on hot days. My mpg sucks anyway.
