Vehicle Fitment

Also fits (verify with VIN):

Signs of Failure

• Coolant leaks – visible drips or puddles under the vehicle from the thermostat area

• Engine overheating – temperature gauge reading above normal

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

• Cracking, swelling, or deterioration – visible damage to the plastic pipe

• Sweet coolant smell – from the engine bay

💡 The factory plastic water outlet pipe is prone to cracking and failure over time due to heat cycling – upgraded metal alternatives offer improved durability-. A sudden failure can lead to rapid coolant loss and serious engine damage.

Critical – Verify Your VIN Before Ordering

Coolant hoses are VIN‑, engine‑, and model‑year‑specific. Variations in engine type (5.0L NA vs. 5.0L SC), production date, and chassis configuration 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. When replacing the thermostat coolant hose, it is recommended to perform a coolant flush to remove any sludge that may have formed over time. Replace coolant with OEM-specified fluid at the correct mixture ratio after installation. Inspect all hose connections and clamps during replacement.
