Vehicle Fitment

⚠️ Important: This hose is for 3.0L V6 naturally aspirated petrol engines only. It does not fit supercharged variants, 2.0L petrol engines, or diesel models. Fitment varies by model year, production date, and VIN range.

Signs of Failure

• Coolant leaks – visible drips or puddles under the vehicle

• Engine overheating – temperature gauge reading above normal

• Loss of coolant – recurring need to top up the reservoir

• Cracking, swelling, or softening – visible damage to the hose

• Sweet coolant smell – from the engine bay

💡 Radiator hoses degrade over time due to heat cycling and coolant exposure – regular inspection is recommended. A sudden hose failure can lead to rapid coolant loss and serious engine damage.

Critical – Verify Your VIN Before Ordering

Radiator hoses are VIN‑, engine‑, and model‑year‑specific. Variations in engine type (3.0L N/A vs. supercharged vs. diesel), production date, and VIN range affect fitment. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. Inspect all hose connections and clamps during replacement – replace any corroded or damaged clamps. Replace coolant with OEM-specified fluid at the correct mixture ratio after installation. Bleed the cooling system to remove trapped air.
