The HPS high temperature 3-ply reinforced silicone radiator hose kit (part number 57-2055-BLK) 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).
The premium grade reinforced silicone hoses with high-heat resistance are made with correct bends and curves for perfect fitment.
It includes 100% stainless steel non-perforated embossed hose clamps for easy installation, which do not cut through the silicone hose.
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.
The race proven design is engineered for extremely high temperature service (Max.
350F) and prolonged exposure to under-hood and coolant heat.
It is compatible with OEM part numbers 21501-1MC0A, 21503-1CA0A, 21047-1CA0A.
Note: The silicone hose water permeation rate is 10 to 15 times greater than that of standard EPDM rubber hose.
Checking the water level regularly is highly recommended when silicone coolant hoses are used in a daily driving vehicle.
Warranty: 2 Years.
