i dont know if anyones done it but thats how i was going to go on my escos

as far as i know you need a ribbed belt pulley for crank, water pump and alternator, you will also use a 2wd alt bracket and tension it like you would ona twin belt system

the p/s pump would be v belt and need to be spaced out to keep it inline with the front of the crank pulley as this would use the v groove on the crank usually for aircon
