I will be pulling down the AC system sometime in the near future due to a leak. The AC has never been what I consider great in this truck in 100 degree weather with 100% humidity. Highway speeds vent temps will hover about 48 and in traffic climb to 60. One downside is the serpentine condenser which I don't plan to change due to its fairly new.
Currently the system has a fixed OE orifice tube in it that is .072". I am thinking about going with the variable orifice tube. Does it help or would the smaller orifice tube such as .062 or .067 be a better choice.
