Constructed from corrosion-resistant materials and engineered to withstand constant exposure to heat, coolant, vibration and pressure fluctuations, this hose clamp helps ensure the integrity of the cooling and heating circuits. Proper hose retention is essential for maintaining coolant flow, heating performance and overall engine cooling system reliability.  

What This Product Does:

• Secures heater hoses to pipes, fittings and cooling system components.
• Maintains a leak-free coolant system connection.
• Provides consistent clamping force under varying temperatures.
• Prevents hose movement caused by vibration and pressure changes.
• Supports efficient coolant circulation through the heating system.
• Helps maintain correct cabin heating performance.
• Contributes to overall cooling system reliability and safety.

Symptoms Of Wear Or Failure:

• Coolant leaks around heater hose connections.
• Visible corrosion or rust on the clamp.
• Loose or slipping heater hoses.
• Coolant residue around hose fittings.
• Reduced heater performance due to coolant loss.
• Sweet coolant odour from the engine bay.
• Low coolant level warnings.
• Overheating concerns caused by coolant leakage.
• Visible clamp deformation or loss of tension.

Why Replacement Matters:

• Heater hose clamps are exposed to continual heat cycles, moisture, coolant chemicals and engine vibration. Over time, corrosion, metal fatigue or loss of clamping tension can reduce their ability to maintain a secure seal between hoses and cooling system components.
• A failing hose clamp can allow coolant to escape, leading to reduced heater efficiency, cooling system pressure loss and potential engine overheating. Even minor coolant leaks can worsen over time, increasing the risk of damage to cooling system components and resulting in costly repairs.
• Replacing a worn or damaged heater hose clamp restores proper hose retention, prevents coolant leaks and helps maintain the efficiency and reliability of the cooling and heating systems. An OE Match replacement provides factory-style fitment, dependable clamping performance and long-term durability, ensuring reliable operation of your Porsche cooling system.

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.
