The HIGHROAD radiator for the machine was developed in the United States of America to suit the thermal properties of the 6-cylinder Lexus ES350 engine. The radiator relies on "dense parallel channels" technology that increases heat transfer efficiency from the coolant to the outside air by 25% compared to commercial radiators. High-purity aluminum: Uses oxidation-resistant aluminum alloys to ensure the internal passages do not clog. Thermoplastic tanks: The upper and lower plastic parts are designed to withstand high cycle pressure without cracks at the corners (a common problem in traditional radiators). Signs of radiator damage in Lexus ES350: Fluctuating temperature indicator: Especially during long stops or when running the air conditioning in midday hours. Pink fluid leakage: Noticing dry coolant spots (light pink color) on the radiator body or connections. Hose swelling: Resulting from excess steam pressure caused by radiator cell blockage. "Burnt sugar" smell: A distinctive smell emanating from the front of the car indicating coolant vaporization from a tiny vent hole. Why choose the American HIGHROAD for your Lexus ES?
