Just in case anybody thinks I think, I know a lot about anything I really don't.
My job in HVAC business life was to read everything pertaining to the business. (retired now)
Anyway, I just put dyed PAG and a couple cans of 134 in my own system. I don't expect it to last more than a day or two but I need to get the dye in there and circulating.
Pulled a vacuum on the system, put the end of the low side hose right in the oil bottle, open the valve and watched it draw right into the receiver, being careful not let the hose pull air, an ounce or two was left in the bottom of the oil bottle.
Next ( after hunting down a ACME thread adapter for R134a refrigerant can tap valves) open the valve on the inverted new can on the high side and sent liquid directly in, 12oz cans so probably about 20 oz in there. Started the engine started the AC, surprise surprise surprise (re Gomer) compresser turned on, started pumping started cooling inside the cab! And immediately started short cycling, as I've often mentioned about R134a: after 10 minutes or so it was stabilizing and cutting out on low pressure way way less. The temperature is in the mid-80s today.
Notice I didn't give anybody pressures because they don't really matter at this point but they were in the ballpark for making air conditioning effect.
While looking over the system as it was running, I did notice it was an R12 system changed over to 134 so I guess this truck 1994, was one of those not changed over at the factory.
So, I have a 1994 Ranger with good air conditioning that may or may not have a very large leak!
