Hello - I am new to this forum and have a question for you all.
I just recently acquired a '94 Trans Sport 3.8
The van sat for over a year in the harsh Michigan weather-
the A/C is froze - thus not allowing the serpentine belt to move-
I don't care about havin A/C - so I would rather not spend the $300 bucks on a new one-
Is there a way to bypass the A/C ?
any help would be greatly appreciated

Hi onepercent:
Your A/C compressor pulley wheel and clutch plate should spin freely when the A/C is switched off. Remove the serpentine belt and try to turn the pulley wheel by hand , if the wheel will not turn then the clutch hub bearing is siezed. A new bearing is required and will cost approx $30.00 + fitting. All this can be done without touching the A/C compressor internals. Once the bearing is replaced you can use the vehicle even if the A/C system is empty and the compressor will not engage.

do you think it's something i could do myself -
keep in mind i'm no pro - but not a complete idiot either -
thanks again

You can buy a shorter serpentine belt that avoids the A/C pulley. I have one indeed, because with my '93 Transport 3.8 I used to completely disable the A/C in winter and wrap the a/c compressor and clutch in plastic to avoid salt from degrading these components.
. With A/C the serpentine belt is 102.5", PN 1025K6. With out A/C the belt is 72.5", 30" shorter, PN 725K6. A valid listing in reference books is for 1989 Olds Delta 88 with out A/C because there is no such listing for Transport...
