    Four bolts holding on the water pump pulley: 25 Nm (18 lb-ft).

    Crankshaft pulley bolt: "Install the bolt and washer. Tighten the bolt in four stages. Stage 1: Tighten the bolt to 90 Nm (66 lb-ft).
    Stage 2: Loosen the bolt one full turn.
    Stage 3: Tighten the bolt to 50 Nm (37 lb-ft).
    Stage 4: Tighten the bolt an additional 85 to 95 degrees.

    So sayeth the shop manual.
