Topping off dual a/c system??
2001 EXCURSION LTD, 5.4L
Can anyone give me a "rule of thumb" method for topping off the refrigerant in a dual A/C system that uses a TXV in the rear and an orifice tube in the front? Can I use compressor cycle time to approximate the correct charge?
Any suggestions would be greatly appreciated.
THANKS
