Volvo vnl AC problem, charging the system properly?

One more thought, 3 yrs ago when I redid the whole system, I also added some green dye. They sell it already added to 12 oz can of 134a, or they sell it in a liquid form, much cheaper. I only added a small amount. Also bought infra light and glasses kit. I doubt I’ll ever use the kit, as the dye showed up bright green right at the leaking condenser, also came in handy just now, as I had the leaking fitting. Well worth it to add the dye, for future leaks.I never bothered in the past, didn’t realize how good it shows up when there’s a leak.

 

put put gauges on it

 

I just had to charge mine. Had a leak at hose end.Luckily, I have re usable ends. Simply cut the bad end of hose, and re did it. Hose was stuck in fitting, bought another fitting at TA $20, put 5 cans in it. Good to go. I’ll pull a vacuum soon enough, and fill it again As long as you put the required amount in weight. No need for gauges. It’s on the money.
