Install a new gasket onto the water pump and put the 3 bolts and 3 nuts in place before torquing them to 8.0 Nm (82 kgf-cm, 71 inch lbs.). A 10 mm socket hexagon wrench should be used to install the timing belt idler sub-assembly No.1 through its plate washer and timing belt idler No.1 with the pivot bolt, ensuring a 34 Nm (347 kgf-cm, 25 ft. lbs.) torque. Install the timing belt No.3 cover followed by camshaft timing pulley with Special Service Tools 09960-10010 (09962-01000, 09963-01000) and 09249-63010 and timing belt idler sub-assembly No.2 then inspect the timing belt before hanging the belt with Special Service Tool 09960-10010 (09962-01000, 09963-01000).
