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.
