I'm looking for the timing belt specification for my 1999 Subaru Legacy Outback. I need the number of teeth that are supposed to be between each mark, as my (replacement) belt came without the white marks. Do I need to use specific tooth numbers between marks on pulleys, or do I just line up the pulleys and then put the belt on however it fits?
I don't like those "preprinted" marks anyway. You are much better off following the sprocket alignment pictures below.
After the belt is installed and the tensioner properly set, crank the engine over BY HAND (in the running direction) at least four full revolutions, and check that all marks come back to perfect alignment.
I've done dozens of these, and following those silly marks painted on the belt only leads to trouble. Sometimes they are not exactly right from the "belt factory", and sometimes you start with the wrong mark - only to pull it off and start over.
I prefer Gates, Continental, or OEM Subaru, but YMMV. A cheap belt is not money saved. Replace the water pump while you are in there. Same theory. Even though Subaru drives the water pump with the smooth "backside" of the belt [smart move, Subaru] if it needs the belt, it could probably do with a new water pump, and fresh coolant. The best kits come with everything: tensioner, belt, idlers, water pump, gaskets, "grenade pin", date/mileage sticker for the airbox, etc. - even DETAILED instructions on the alignment, torques, and installation procedure. Conti or Gates. Money well spent IMNHO.
Take your time and Good Luck!
