I can't seem to get the fan shroud into the bottom side clips. What is the proper shroud installation procedure? I installed the clutch fan with the shroud loose so I could hold and tighen the bolts on the clutch fan because it's so heavy and hard to mount to the water pump pulley. Should I disasemble and mount fan shroud first, then instal clutch & fan??? I seem to have forgot the procedure, but then again, I never had a fan clutch on the motor previously. Tks Joe
