how to removed crankshaft pulley

It doesnt just unbolt and come off, there is a large bolt holding it on that requires an impact driver to dislodge and you need to pull the radiator to get at it. (Some have reported success using a breaker bar and cranking the starter, I wouldnt go that route tho) Once the bolt is off you need a bolt puller to get the balancer off. However he is right dont just go replacing a timing belt, diagnose the issue correctly first.
