HPS red high temp 3-ply reinforced silicone Heater hose kit (part number 57-1702-RED) replaces 2007-2011 Toyota Tundra 5.7L V8 stock OEM rubber heater coolant hoses with premium grade high-heat resistance material which meets or exceeds OE specifications (Maximum temperature rating: 350F). Compared to the local auto parts store universal hoses, HPS silicone Heater hose kit has all the correct bends and curves for a perfect fitment. HPS silicone coolant hose kit includes 100% stainless steel non-perforated embossed hose clamps for easy installation, which do not cut thru the silicone hoses. HPS silicone hoses can prevent and fix the coolant leaking and engine over heating problem caused by cracked, damaged or collapsed OEM rubber coolant hoses. Excellent for extreme ambient and radiant temperature conditions, HPS silicone hoses can withstand the harsh high temperature and high pressure operating conditions of the engine yet still maintaining peak efficiency during daily driving or racing competition. HPS silicone hose kit is backed by HPS Performance Products limited lifetime warranty.
