Oil the threads on the lines and in the expansion valve and turn your nuts counter clockwise by hand till you feel where the treads would catch and then give them a little tap on top of the line gently forcing the threads tightly together. Then gently wrench them clockwise to tighten them.
I just did a dash out changing the evaporator and expansion valve on my 1987 420 SEL and I know it’s a …, but be patient.
Connect the top two lines and the suction line on the bottom before tightening them. After those three are tight then do the line from the dehydrator since the bend on this line rests under the suction line.
And by the way you will need a set of crows feet to get them torque to specs!
Hope This Helps!
