The HPS Blue high temperature 3-ply reinforced silicone radiator hose kit (part number 57-1859-BLUE) replaces the stock OEM rubber lower and upper radiator coolant hoses with high-heat resistance material that meets or exceeds OE specifications (Maximum temperature rating: 350F).
Made with correct bends and curves, the premium grade high-heat resistance reinforced silicone hoses ensure perfect fitment.
For easy installation, it includes 100% stainless steel non-perforated embossed hose clamps that do not cut through the silicone hoses.
The coolant leaking and engine overheating problem caused by cracked, damaged, or collapsed OEM rubber lower and upper radiator coolant hoses can be prevented and fixed.
Compatible with OEM part numbers 16571-31350 and 16572-31350, the race proven design is engineered for extremely high temperature service (Max.
350F) and prolonged exposure to under-hood and coolant heat.
Warranty: 2 Years.
Remark: The silicone hose water permeation rate is 10 to 15 times greater than standard EPDM rubber hose.
Checking the water level regularly is highly recommended when silicone coolant hoses are used in a daily driving vehicle.
