ok the best way is off a fj post basically with the cams and crank locked, exhaust gear loose intake gear tight. you turn the intake gear towards the windshield and watch the oil come out of it and then turn it back towards the bumper untill it comes to a solild stop. the problem is when you remove the old belt the leftover oil in the gear forces it to turn towards the windshield when it needs to be turned all the way to the front bumper to not get a code. I know this sounds hacked up but once you get to putting the belt on it would make since the key is DONT loosen the intake gear!
The best modifications cannot be seen from the outside.
I work on Fords all day so more than likely i know more about your car than you.
