1. First remove the fixing nut of the cooling chamber tank from the shock absorber seat, and then remove the cooling chamber tank from the cooling chamber tank bracket and put it aside.

2. Insert the intermediate ratchet into the square hole of the tensioner and rotate the tensioner counterclockwise to remove the belt. Then before installing a new belt, it is necessary to check whether each pulley is normal, mainly whether the rubber connection between the inner ring and the crankshaft pulley has been disconnected. If disconnected, replace the crankshaft pulley.

3. Ensure that the belt completely enters the groove of the pulley and the belt transmission route is correct. Insert the middle ratchet into the square hole near Zhang, rotate the tensioner counterclockwise to install the drive belt, and then install the antifreeze recovery tank. Tighten the nut of the antifreeze recovery tank to 3.3 mm During installation, pay attention to that the lower part of the recovery tank should be inserted into the bracket. The end of the hose from the recovery tank to the water tank must be flush with the neck of the water tank filler, and the hose cannot rub against the generator belt.
