Gates 08-13 Infiniti G37 V-6 3.7L Upper Molded Coolant Hose

When you're replacing a cracked or leaking upper radiator hose on your Infiniti or Nissan, a direct-fit molded hose like this Gates 23339 is the way to go. This hose is specifically shaped to follow the factory routing, making installation straightforward and ensuring it won't rub against other engine components. It's designed to handle the heat and pressure cycles your cooling system experiences, keeping your engine running at the right temperature.

Gates uses a EPDM rubber construction for this hose, which is known for its resistance to heat, ozone, and coolant chemicals. This means it's built to last and won't degrade prematurely under the hood. The molded design means you won't have to fight with a stiff hose trying to bend into place, and it fits snugly onto the radiator and thermostat housing connections.

This hose fits a wide range of Infiniti and Nissan models, including the G37, 370Z, and EX35. Make sure to check the fitment details to confirm it's the right part for your specific vehicle.
