I'm prepping to retrofit the AC system from a '93 into my '90. The suction hose (compressor to accumulator) has a crack at the metal squiggle where it meets the compressor. I find this to be fairly common. The part number stamped on the hose is 3540458. Volvo parts databases tell me that it's been superseded to 3540604, which shows it's applicable for 91-93. I do not have a 91-92 accumulator in front of me to compare threads, but I'm led to believe that the '93 accumulator does have different threads than the 91-92 system. 3540604 is also shown as the replacement for 3537036, which is the 91-92 hose. I'm guessing there's a TSB that also updates the accumulator/drier p/n to one that works for 91-93 with r134a? Does anyone know what's going on here?
edit: My accumulator is 3537542, but 9131972 is also listed as 1993 fitment, possibly an updated part?
