Drive Belt for cars WITHOUT Air con
The Genuine Porsche 99610215167 water pump drive belt is an OE Poly-V / serpentine belt for selected Porsche 996 and 986 Boxster models without air conditioning. It drives the water pump and related auxiliary components according to the non-A/C belt routing, supporting correct coolant circulation and reliable accessory-drive operation. Ideal for routine servicing or replacing a cracked, noisy, slipping or worn original belt.

Fits:
Porsche 996 Carrera 1998 - 2005
Porsche 986 Boxster 1997 - 2004

Diagram ref no 27

This belt is specifically for Porsche 996 and 986 Boxster models without air conditioning. It is not the correct belt for vehicles fitted with air conditioning, as the belt routing and length differ.

What This Part Does / Functions
•  Drives the water pump from the engine pulley system
•  Supports correct coolant circulation through the engine
•  Helps maintain stable engine operating temperature
•  Drives other auxiliary components according to the non-A/C belt routing
•  Maintains correct accessory belt tension and pulley engagement when installed correctly
•  Helps prevent belt slip, squeal and accessory-drive faults
•  Provides correct OE Porsche belt length, rib profile and fitment
•  Replaces a cracked, worn, stretched, glazed or noisy original belt.

Why Replace This Part?
The drive belt is a service wear item and is exposed to heat, tension, pulley contact and engine movement. Over time, the belt can crack, glaze, fray, stretch or lose grip on the pulleys. A worn belt can cause squealing, slipping, reduced water pump performance, charging issues or complete accessory-drive failure. Replacing it with a Genuine Porsche OE belt helps restore reliable auxiliary drive operation and supports correct cooling system performance. On cars without air conditioning, using the correct belt length is essential because the routing is different from A/C-equipped models.

When to Replace This Part
•   If the belt is cracked, glazed, frayed or visibly worn
•   If the belt squeals, slips or makes noise during engine operation
•   If the belt has stretched or no longer runs correctly
•   During scheduled service or preventative belt replacement
•   When replacing the water pump, belt tensioner or idler pulleys
•   If the belt has been contaminated by oil, coolant or debris
•   If accessory-drive faults or cooling issues are linked to belt slip
•   When converting or servicing a vehicle with non-A/C belt routing.

Where It Fits on the Car
This belt fits on the engine accessory drive system. It routes around the crankshaft pulley, water pump pulley, idler pulleys and tensioner according to the factory without air conditioning belt layout.

Replacing the belt at the recommended service interval helps maintain efficient cooling system performance and prevents unexpected belt failure.

When to Replace the Water Pump Drive Belt
•   Visible cracks, fraying, or glazing on the belt
•   Squealing noises from the auxiliary drive system
•   During water pump replacement
•   During major engine servicing
•   If the belt has been contaminated by oil or coolant
•   At the manufacturer's recommended replacement interval

It is designed to match the original-style fitment and function. This replacement belt helps drive the water pump, supporting correct coolant circulation and reliable engine cooling performance.

Fits:
Porsche 996 Carrera 1997 - 2005
Porsche 986 Boxster 1997 - 2004

Diagram ref no 27

The water pump drive belt transfers rotational drive from the engine pulley to the water pump. This allows coolant to circulate through the engine and radiator system, helping regulate engine temperature and protect the engine from overheating.

Functions
•  Replaces the water pump drive belt
•  Drives the engine water pump
•  Supports correct coolant circulation
•  Helps maintain stable engine operating temperature
•  Suitable for vehicles without air conditioning

Why Replace This Part?
Water pump drive belts wear over time due to heat, engine vibration, pulley contact, age, and tension changes. A worn belt can crack, glaze, stretch, fray, squeal, slip, or fail completely. If the belt fails, the water pump may stop circulating coolant, which can lead to overheating, coolant temperature warnings, or serious engine damage. Replacing the belt helps maintain dependable cooling system performance.

When to Replace This Part
•   The water pump drive belt is cracked, glazed, frayed, loose, or worn
•   Belt squeal or chirping is heard during start-up or acceleration
•   Coolant temperature rises higher than normal
•   The water pump, pulleys, or tensioning components are being serviced
•   Preventative belt replacement is being carried out during scheduled maintenance
•   The cooling system is being inspected or repaired
•   The vehicle is undergoing Porsche 996 or Boxster 986 engine service.

Where it fits on the car
This belt fits within the water pump drive system on Porsche 996 and Boxster 986 models without air conditioning. It runs around the relevant pulleys according to the factory belt routing.
