Hey man great video, I'm currently using it to help me replace mine. Is there supposed to be coolant leaking out of the bolt hole for the top tensioner pulley?
Good on ya! I'm just not so sure if the diesel 4jg2 is popular. If you're after the brand of the timing belt, check if they have continental, gates, bando, or genuine isuzu belt. Is your unit going to be a 4jg2 or 4jx1?
