Silicone Radiator Coolant Hose Kit

The HPS Performance Products 57-1859-BLK is a high-temperature, 3-ply reinforced silicone radiator coolant hose kit. It serves as an ideal replacement or performance upgrade for stock OEM rubber hoses, which are prone to weakening and premature failure over time. This kit is specifically engineered with the correct bends and sizes for a precise fit, making it easier to install than universal hose options. It is rated to withstand operating temperatures of up to 350°F (177°C), ensuring sustained peak efficiency during both competitive use and daily driving. The kit includes 100% stainless steel, industrial-grade embossed hose clamps that are designed not to cut through the hoses, ensuring a secure and long-lasting connection. This HPS silicone radiator hose kit is designed to fit a range of Lexus models, including the 2014-2017 Lexus IS350 and the 2016-2020 Lexus GS350. It replaces OEM part numbers 16571-31350 and 16572-31350. Fitment is critical for performance and safety; while this product fits a wide array of vehicles, buyers are encouraged to confirm compatibility for their specific year, make, model, and trim using the available search tools. Retailers offer assistance in confirming fitment, and in cases where their recommendation is incorrect, they may accept returns without restocking fees if the item is in like-new condition.
