•  Supports correct coolant circulation
•  Helps maintain accurate camshaft timing and belt tracking
•  Suitable for Porsche 928 S4 and 928 GTS front engine service.

Why Replace This Kit?
Water pump and timing belt components are exposed to heat, coolant, bearing load, mileage, age, and constant engine operation. A failing water pump can leak, become noisy, or reduce coolant circulation. A worn timing belt can crack, stretch, lose teeth, or fail, while worn rollers can become rough, noisy, loose, or seized. Replacing these parts together during service helps protect the engine and supports long-term reliability.

When to Replace This Kit
•  The timing belt service interval is due
•  The water pump is leaking, noisy, or showing bearing wear
•  The timing belt is cracked, worn, contaminated, stretched, or aged
•  Camshaft rollers are noisy, rough, loose, or seized
•  Coolant circulation or engine temperature issues are present
•  Front engine timing components are being serviced
•  Preventative replacement is being carried out during major maintenance.

Where it fits on the car
This kit fits at the front engine timing belt and water pump area on Porsche 928 S4 and 928 GTS models. It supports both the engine cooling circuit and the camshaft timing belt drive system.
