1994 volvo 850 A/C refill refrigerant

[cambiecbc]

I just used $22 for Red Tek leak stop & refrigerant to refill the A/C of 94 volvo 850.
We can only get Red Tek 12a in Canada whether than r134a in US.
Just upload some photos to share for those who are interested. There are lots
of instructions of how to refill in the forum.
Low side port to fill:

It took less than an hour and the temp dropped 15C.
