In some Nissan Pickups of that year, the fan clutch is actually integrated with the water pump as an assembly. Therefore, the fan clutch cannot be separated from the water pump. There are six bolts holding the water pump to the engine block; remove those bolts and the water pump/fan clutch assembly should come out as a unit.

A Datsun 280ZX clutch may not engage due to several potential issues, such as low or contaminated clutch fluid, a worn or damaged clutch disc, or a faulty release bearing. Additionally, problems with the clutch master or slave cylinder can prevent proper hydraulic pressure from transferring, leading to disengagement issues. Inspecting these components and ensuring proper fluid levels can help diagnose the problem. If these checks don't resolve the issue, further investigation into the clutch assembly may be necessary.
