Thank you very much 🙏🏽 very clear!I start by placing the belt over the rear cam, looping it under the water pump (#4), then over the front cam (#3). If the cams are on their marks, there should be no slack between. Then continuing down the right side, pulling the belt tight over the Idler pully (#2) down around the crankshaft gear. If the crankshaft gear is on its mark, there should be no slack in the belt down the right side. All slack should be on the tensioner side before pulling the pin.
