Can anyone tell if the pulleys from an m44 (crank,water pump,alternator,PAS pump) all swap over to an m42(no air con) ... Does an m44 have tooth missin from its crank pulley same as 42 for crank sensor... thanks

as far as i remember, the M44 uses the same timing as the M42 apart from it has a coil per cylinder, so effectively, everything should fit

why do you want to change it??
