Porsche 928S2 4.7L 1984 - 1986

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.

Functions
•  Replaces the timing cam belt
•  Includes camshaft tensioner roller
•  Includes camshaft idler roller
•  Supports correct camshaft timing
•  Helps maintain proper belt tension and belt tracking
•  Replaces worn, noisy, rough, seized, or aged timing components
•  Suitable for Porsche 928 timing belt service and preventative maintenance.

Why Replace This Kit?
Timing belt and roller components are exposed to heat, age, mileage, engine load, and constant rotation. A worn timing belt can crack, stretch, lose teeth, or fail without warning, while worn rollers can become noisy, rough, loose, or seized. Replacing the belt and rollers together helps protect the timing system and supports reliable engine operation.

When to Replace This Kit
•   The timing belt service interval is due
•   The timing belt is cracked, worn, contaminated, stretched, or aged
•   Rollers are noisy, rough, loose, or seized
•   Belt tracking or tension issues are present
•   Front engine timing components are being serviced
•   Preventative replacement is being carried out during major maintenance
•   The vehicle is undergoing Porsche 928 engine service or restoration.

Where it fits on the car
This kit fits at the front engine timing belt drive area on Porsche 928 models from 1978 to 1986. It supports the camshaft timing belt system according to the factory timing layout.

About Water / Coolant Pumps

Water / Coolant Pumps – Reliable Engine Cooling for Porsche Vehicles

Water / coolant pumps are at the heart of your Porsche’s cooling system. Their job is to circulate coolant through the engine, radiator, and heater core, maintaining the correct operating temperature and preventing overheating. A properly functioning water pump ensures efficient heat transfer, optimal performance, and long-term engine reliability.

At Design911, we supply a wide range of genuine and high-quality water pumps for Porsche models including 911, Boxster, Cayman, Cayenne, Macan, Panamera and the transaxle cars. Each pump is precision-engineered to deliver consistent coolant flow, high durability, and dependable performance - ensuring your Porsche’s engine stays cool under all driving conditions.

What Do Water Coolant Pumps Do?

Water pumps are a critical part of your engine’s temperature control system. They:

  • Circulate coolant between the engine block, radiator, and heater system.
  • Regulate temperature by dispersing heat efficiently throughout the system.
  • Maintain coolant pressure for consistent engine operation.
  • Support performance and longevity, preventing damage from excessive heat.

Without a properly working water pump, coolant circulation stops — leading to overheating, loss of performance, and potential engine failure.

Why Do Water Coolant Pumps Fail?

Even the most durable water pumps can fail over time due to heat, age, and coolant contamination. Common causes of failure include:

  • Bearing wear or seal leaks caused by prolonged use or poor coolant quality.
  • Corrosion or pitting from old or incompatible coolant mixtures.
  • Cracked impellers or worn components reducing flow efficiency.
  • Coolant leaks around the housing or pulley.
  • Age-related wear, especially in high-mileage vehicles.

Signs of failure include visible coolant leaks, high engine temperature, whining noises from the pump area, or reduced cabin heating.

Why Replace a Faulty Water Coolant Pump?

A failing water pump can cause severe engine overheating, loss of coolant, or total breakdown. Replacing a worn pump restores reliable cooling and helps protect your engine from costly damage.

Benefits of replacement include:

  • Restored coolant circulation and cooling efficiency.
  • Improved engine reliability and performance.
  • Prevention of leaks, overheating, and corrosion.
  • Long-lasting, high-quality construction for dependable operation.

All water pumps in this range are built using high-strength materials, precision impellers, and sealed bearings designed to deliver durability, quiet operation, and efficient coolant flow over time.


Porsche Water Pumps: Common Issues, Fixes, and Upgrades #porsche #porscheparts #porscheupgrade

In this tech talk, Lawrence from Design 911 breaks down everything you need to know about water pumps for Porsche models. From the iconic 911 to the Cayenne and Macan, discover why the water pump is one of the most crucial components in your car’s cooling system. 

Learn how water pumps work, the common signs of failure, and why regular replacement is essential to avoid catastrophic engine damage.

Whether you're maintaining your Porsche or considering a water pump upgrade, this video covers original and aftermarket options, as well as the pros and cons of plastic vs. metal impellers. Watch now to keep your Porsche running at its best!
