The cooling system in high-performance SUVs like the Cayenne 4.8 L must manage significant heat generated by the V8 engine, especially during heavy load, highway driving, towing, or hot ambient conditions. Over time, radiator cores can lose efficiency and material integrity, and hoses can harden, swell, or crack, leading to leaks or reduced coolant circulation.
This kit forms the core of the Cayenne’s coolant circulation loop at the centre radiator position. The radiator dissipates engine heat through airflow while the hoses route coolant in and out of the heat exchanger. Proper function of these components maintains optimal engine temperature, prevents overheating, supports heater performance, and protects critical components like cylinder heads, head gaskets, and turbocharger interfaces from thermal stress.
Function
• Radiator: Transfers heat away from coolant to ambient air
• Coolant Hoses: Provide secure, leak-free coolant routing
• Mounts: Secure radiator in place with correct vibration isolation
• Clamps: Ensure watertight connections under pressure and thermal cycling
Over time, radiator cores and coolant hoses degrade from heat cycling, pressure fluctuations, and environmental exposure. A weakened radiator or aging hoses can cause coolant leaks, overheating, inconsistent temperature readings, heater performance issues, and increased stress on the engine cooling network. Replacing these components as a matched kit increases reliability, restores cooling efficiency, and reduces the risk of roadside breakdowns and expensive engine repairs.
When to replace:
• Coolant leaks at the radiator or hose joints
• Frequent temperature gauge fluctuations
• Hose bulging, cracking, or soft spots
• Bent, collapsed, or clogged radiator fins
• During scheduled cooling system service
• After front-end collision or coolant system work

What This Product Does:
- Vents air and vapor from the coolant cooler system
- Helps regulate cooling system pressure
- Supports consistent coolant circulation
- Reduces strain on hoses, seals, and cooling components
Symptoms Of Wear Or Failure:
- Coolant leaks near the coolant cooler or hose connections
- Sweet coolant smell from the engine bay
- Coolant residue or staining around fittings and clamps
- Cracked, brittle, or collapsed hose material
- Loose or leaking hose connections
- Gradual coolant loss requiring frequent top-offs
- Pressure buildup in the cooling system (may cause swelling hoses)
- Steam from under the hood in more severe cases
- Engine temperature running higher than normal if coolant flow is affected
- Replacing a worn or damaged coolant cooler breather line is important because it helps the cooling system properly vent air and regulate pressure during normal engine operation. Over time, heat and constant exposure to coolant can cause the line to become brittle, cracked, or leak.
- If the breather line fails, it can lead to coolant loss, pressure buildup, and added strain on surrounding hoses and seals. This may reduce cooling system efficiency and increase the risk of overheating or costly component damage.
- Installing a new breather line helps prevent leaks, supports stable cooling performance, and protects the engine by maintaining proper system pressure and ventilation.

The radiator is the primary heat exchanger in the cooling system. Coolant heated by the engine flows through the radiator’s core, where airflow draws heat away before the coolant returns to the engine. This circulation:
• Maintains stable engine operating temperatures
• Prevents overheating under load or heat stress
• Supports efficient engine performance and emissions
• Ensures proper cabin heating when required
A failing or inefficient radiator can lead to engine overheating, poor climate control performance, coolant loss, and accelerated wear on other cooling system components. Symptoms such as rising temperature gauge readings, coolant leaks, or reduced heater output indicate that the radiator may no longer be functioning optimally. Replacing it with an OE Match radiator ensures reliable cooling performance and helps maintain engine health and longevity.
When to replace:
• Persistent engine overheating
• Visible coolant leaks or core corrosion
• Bent, damaged, or clogged cooling fins
• During front-end repair or cooling system service
• After water pump, thermostat, or main hose replacement
