Description:
Genuine OEM Nissan Lower Radiator Hose, part number 21503-9BT0B, for the 3.8L V6. This factory hose carries cooled coolant from the radiator back to the engine, completing the coolant circuit that keeps engine temperature in check.
Rubber radiator hoses harden and crack with age and heat cycling — a failed lower hose can drop coolant quickly and lead to overheating if not caught early. Watch for visible cracking, bulging, or coolant leaks near the hose connections as signs it's due for replacement.
Fitment:
- Nissan Frontier, 2020–2024 (PRO-4X, PRO-X, S, SV, 3.8L)
Compatibility Warning: ⚠️ This hose is specific to the 3.8L engine. Please confirm your exact year and trim before ordering, or provide your VIN so we can verify correct fitment.
Condition: New, Genuine OEM Nissan Part
Walser Nissan Wayzata is an authorized Nissan dealership, and all parts sold are genuine OEM Nissan parts backed by manufacturer warranty. Questions about fitment? Message us before you buy — we're happy to verify compatibility with your VIN.
