How To Retrofit R12 To R134

It Is A Lot Easier Than You Might Think

BE SURE TO HAVE THE R12 REMOVED AND CAPTURED BIG BROTHER IS WATCHING !!!!!!!!!!!

I have converted my 1978 Trans Am and a 1989 Ford F150 they both cooled as well as R12. So don't be scared away from this it gets too hot out there (I live in Texas if it works here it will work where you live).

Check and repair all leaking hoses and parts.

After removing the old R12 properly there are several companies that make retrofit kits. They are usually about $20.00 to $25.00 with fittings and oil. Remove the compressor and drain out the old oil. Install the new correct type oil and reinstall compressor. Next you will need to replace the dryer (the big aluminum can).

The kit will show you how to know which valve to put on the high and low side. Usually the low side will be on the drier. Be sure to have a wrench handy as there is a self sealing compound on the new fitting. Install the fittings on the high and low side. On the kits I used the old valve stem stayed on the valve, read the directions with your kit. Now it is time to install the R134, put in one can to start the compressor then add a can of oil. Now add the rest of your R134 your amount may very both of the ones I have done took 2 to 3 cans. There is a gauge that I purchased at Pep Boys that looks like a tire gauge tester that can help you with how much to put in (it cost less than $5.00).

Now your ready to hit the road in a cool car.
