This HPS High Temp 3-ply Reinforced Silicone Radiator Coolant Hose Kit is designed to replace stock OEM rubber upper and lower radiator hoses which weaken and fail over time. With premium quality silicone and performance inspired design, this coolant hose kit can withstand the harsh, high temperature and high pressure operating conditions under the hood through a wide range of driving conditions.
