Diagram ref no: 1, 9, 10
The kit helps maintain correct camshaft timing, belt routing, and belt tension within the engine timing system. The timing cam belt synchronises crankshaft and camshaft movement, while the tensioner roller and idler roller guide and support the belt as it operates.

Fits:
Porsche 928 S4 5.0L
Porsche 928 GTS 5.4L
The kit helps restore coolant circulation and timing belt drive reliability. The water pump circulates coolant through the engine cooling system, while the timing cam belt, camshaft tensioner roller, and camshaft idler roller support correct belt routing, belt tension, and camshaft timing operation.
Functions
• Replaces the water pump
