Hey all,
Has anyone converted an M809 series from direct drive fan to an air clutch setup like the M939 series? I know the fans are different from M809 to M939 even though the NHC 250 engine is in both. Fan spacing is tight on the older trucks but it sure would be nice for the engine to warm up quicker and not hear the fan all the time. Might help the power and MPG a little too.
