To remove the fan shroud, first detach the bolts connecting it to the radiator and reposition the shroud over the fan. Next, take out the fan/clutch assembly along with the shroud, followed by the drivebelts. Mark the crankshaft pulley and vibration damper for reassembly in their original positions, as they are balanced together. Unbolt and remove the pulley, ensuring to mark it and the vibration damper beforehand; the large vibration damper bolt may be tight, so a six-point socket and breaker bar are recommended for loosening. Remove the bolt from the front of the crankshaft, preventing it from turning by wedging a large screwdriver between the teeth of the starter ring gear against the transmission housing. Use a puller to detach the vibration damper, ensuring it applies force only to the hub to avoid damage. Clean the crankshaft nose and seal contact surface of the vibration damper, keeping the Woodruff key in the crankshaft keyway. For installation, lubricate the oil seal contact surface of the vibration damper hub with grease or clean engine oil, aligning the keyway with the Woodruff key. If necessary, use a large washer and bolt to pull the damper into place, or gently tap it with a soft-face hammer or a block of wood. Tighten the bolt to the specified torque, then complete the remaining steps in reverse order of removal. Finally, add coolant, check the oil level, and run the engine to inspect for any leaks.
