VOLVO AC R134 refit kit instructions for the 700 series
This is my 1988 745 Volvo which has had the AC RETROFIT
Here are some pictures of the retrofitted parts. Looks about the same.
Here is the filler cap and the filler cap opened. Notice that the filler is a quick release connection. You can also see the U joint from supplementary kit (1)
Here is a picture of the notice stickers you put on the car.
Thanks to Dave Urban for adapting this material.
