2008 Nissan Serena radiator hose — what it does and when to replace it

Radiator hoses are absolutely relevant and used on the 2008 Nissan Serena. Technical documentation for the C25-series Serena with the MR20DE 2.0‑litre petrol engine confirms a conventional liquid-cooling layout with an upper radiator hose (engine outlet to radiator top tank) and a lower radiator hose (radiator bottom tank to water pump/thermostat housing). This is shown in the Nissan Serena C25 Electronic Service Manual (Cooling System section) and corroborated by Nissan’s FAST parts catalogue, which lists distinct upper and lower radiator hose assemblies for this model.
