Updating to r134a Free live beach cams

I was looking at around 0 in parts whether or not I converted to R134a.

The incremental cost in tools for the R134a conversion offset the higher cost of R12 refrigerant and labor (you have to be EPA certified to get and dispense R12) had I not converted.

After I converted my Buick, I performed the following comparison.

The R12 system on the Grand National was a 3.25 lb (52 oz) system.

My old switch wouldn't come out, I destroyed it, and had to pay for a new switch.

If you do need to replace this switch, it's important to tell the auto parts store what color your original is (was) and how many prongs are on the electrical connector.

Most 3.8 liter Buick turbos of the era will be similar.

I'm going to assume you know how to replace your compressor.

Checkout the Auto AC board at AC Source There are some good people on there. You do need to flush the old oil out of the system because they don't mix.

Also it's difficult to flush the compressor so odds are it will not last if you don't replace it.

The advice I got most on these systems was between 6-8 oz of oil total, with 2 oz being put in the compressor - I'll get to where the rest goes later.

The oil, Ester oil, is specifically designed for R12-to-R134a conversions and comes in the conversion kits you buy at the auto parts store.
