Water radiator hose clamp, 32-50 mm
Genuine Porsche OE water radiator hose clamp, 32–50 mm, for Porsche 986 Boxster and 996 Carrera models. This original Porsche hose clamp is used in the engine cooling system to secure radiator and coolant hoses, helping maintain a tight, reliable connection between cooling system components.
Sold individually,

Fits:
Porsche 986 Boxster 2.5L / 2.7L / S 3.2L 1997 - 2004
Porsche 996 C2 / C4 / C4S 1998 - 2005

Diagram Ref No 10

Part number 99951249900 is a Genuine Porsche water radiator hose clamp, also listed as 999-512-499-00. It is a factory-style clamp with a 32–50 mm clamping range, used on selected Porsche coolant hose and radiator hose connections.

What This Part Does / Functions
  Secures radiator and coolant hoses to pipe connections
  Helps maintain a tight seal in the cooling system
•  Prevents coolant hose movement or disconnection under pressure
  Helps reduce the risk of coolant leaks at hose joints
  Maintains correct clamping force around the hose connection
  Supports reliable coolant flow and cooling system pressure
  Provides OE Porsche fitment for factory hose sizes and routing
•  Replaces corroded, weakened, damaged or incorrect hose clamps.

Why Replace This Part?
Radiator hose clamps are exposed to heat, coolant, moisture, road dirt and repeated expansion/contraction of the hose. Over time, the clamp can corrode, weaken, seize or lose its ability to hold the hose securely. Replacing an old or damaged clamp with a Genuine Porsche OE 32–50 mm hose clamp helps maintain proper hose sealing and reduces the risk of coolant leaks, pressure loss or overheating. It is good practice to replace hose clamps when removing or replacing coolant hoses.

When to Replace This Part
  If the original clamp is corroded, rusty or seized
  If coolant is leaking from a hose connection
  If the clamp no longer tightens securely
  During radiator hose or coolant hose replacement
  During radiator, water pump, thermostat or coolant pipe repairs
  If the hose has been removed and the clamp is no longer reusable
  When replacing non-original or incorrectly sized clamps
  During cooling system overhaul or preventative maintenance.

Where It Fits on the Car
This clamp fits in the engine cooling system, securing coolant/radiator hoses to pipes, radiator connections or related cooling system fittings.

 It may be used on upper, lower, inlet, outlet or water hose connections depending on model and cooling system layout. Exact position and quantity should be confirmed using the vehicle parts diagram.

Water radiator hose clamp, 32-50 mm
This OE Match water radiator hose clamp is a replacement clamp for Porsche 986 Boxster and 996 Carrera C2, C4, and C4S models. It is designed for hose diameters within the 32–50 mm range and helps secure coolant hoses within the radiator and engine cooling system.

Fits:
Porsche 986 Boxster 2.5L / 2.7L / S 3.2L 1997 - 2004
Porsche 996 C2 / C4 / C4S 1998 - 2005

Diagram Ref No 10

The radiator hose clamp tightens around the coolant hose connection to help hold the hose firmly in place and maintain a leak-free seal. A correctly fitted hose clamp is essential for cooling system pressure retention, coolant flow, and reliable engine temperature control.

Functions
•  Secures coolant and radiator hoses to their connection points
•  Helps maintain a tight, leak-free hose seal
•  Supports correct cooling system pressure
•  Helps prevent coolant hose movement or detachment
•  Suitable for 32–50 mm hose applications
•  Replaces corroded, weak, damaged, or missing hose clamps
•  OE Match replacement for cooling system service and repair.

Why Replace This Part?
Radiator hose clamps can corrode, weaken, distort, seize, or lose clamping force over time due to heat, coolant exposure, vibration, and age. A worn or damaged clamp may allow coolant seepage, hose movement, pressure loss, or overheating issues. Replacing the clamp during coolant hose or radiator work helps restore a secure connection and dependable cooling system performance.

When to Replace This Part
•   The original clamp is rusty, corroded, seized, or damaged
•   Coolant is leaking around the hose connection
•   The clamp no longer tightens correctly
•   The coolant hose has been removed or replaced
•   The radiator, thermostat, water pump, or coolant pipes are being serviced
•   The hose connection shows signs of pressure loss or seepage
•   Preventative replacement is being carried out during cooling system maintenance.

Where it fits on the car
This clamp fits on coolant hose connections within the water radiator and engine cooling system on Porsche 986 Boxster and 996 C2, C4, and C4S models. It is used where a 32–50 mm hose clamp is specified.

About Hose Clips / Screws / Brackets and Fixings

Hose Clips, Screws, Brackets & Fixings for Reliable Coolant System Performance

Hose clips, screws, brackets and fixings are the essential hardware that keeps your coolant hoses, pipes and auxiliary lines securely in place. These compact but critical components maintain stable pressure, prevent coolant leaks, and ensure the entire cooling system functions efficiently under varying temperatures and engine loads. Whether you're upgrading cooling components, performing routine maintenance or completing a restoration project, dependable hose fixings are vital to long-term engine health.

What Hose Clips, Screws, Brackets & Fixings Do

Cooling systems operate under constant pressure and temperature fluctuations.

These fittings perform several key roles:

  • Securing coolant hoses and pipes to prevent movement, abrasion or disconnection
  • Maintaining a reliable seal against leaks and pressure drops
  • Supporting correct routing of hoses throughout the engine bay
  • Preventing vibration damage by keeping lines firmly positioned
  • Ensuring proper airflow and coolant flow by holding components safely in place

From simple worm-drive hose clamps to engineered brackets made for specific vehicle models, these components are designed to ensure stability and performance.

Why Hose Clips & Fixings Commonly Fail

Over time, coolant system fixings endure significant strain from heat cycles, vibration and coolant exposure.

Common reasons for failure include:

  • Corrosion due to moisture or coolant seepage
  • Material fatigue or weakened tension from age
  • Cracked or brittle brackets caused by heat stress
  • Over-tightening or incorrect installation leading to thread damage
  • Degraded rubber insulators on mounting brackets
  • Hose expansion causing clamps to loosen

When these components weaken, the system can no longer maintain proper pressure, often resulting in leaks, overheating, or hose detachment.

Why You Should Replace Worn Hose Clips & Fixings

Replacing worn or damaged fixings with high-quality, precision-made replacement components designed to match original performance levels ensures your cooling system remains secure, leak-free and efficient.

Benefits of replacing them include:

  • Restored clamping strength and sealing reliability
  • Reduced risk of coolant leaks and overheating
  • Proper alignment and support for coolant hoses and pipes
  • Improved durability under heat and vibration
  • Enhanced long-term cooling system resilience

Quality fixings are a small investment that protect major engine components, ensuring dependable performance in both daily driving and high-demand conditions.
