1990 HONDA ACCORD looks to me it's R12 but no sticker saying it has been converted in hopes someone can identify this service port.

 

stock r12 go to autozone or whatever and get a r134 fiting retrofit conversion and get some r134 oil and freon filler up

 

You cannot purchase "Freon" anymore since after 1994. You can though purchase the refrigerant gas 134a. You will need a retrofit kit to use that gas. It will not be as efficient as R-12 Freon in systems designed for R-12 usage, so it will not be cold.

 

Freon (R12) can still be purchased; but, it'll costs a premium. Places like ebay and a few shops still have old stock.

Conversion may be the best bet.

 

geez my bad i meant r134 why would i suggest r135 conversion then say put r12 in it

 

Most of the R12 for sale on ebay is not real R12 but a replacement. Real R12 is not available for resale to the general public. You must be EPA section 609 certified.
Agreed.

 

It will be cold. At least 45 degrees F

 

I found some R-12 on craigslist if you didnt want to do the conversion, but the conversion is simple and easy...

 

I have vacuumed a 90 accord after conversion and recharged with R134a, blows 40 degrees on ambient temps of 100.
