The HPS black high temp 3-ply reinforced silicone radiator hose kit (part number 57-1703-BLK) replaces stock OEM rubber upper and lower coolant hoses with premium grade high-heat resistance material that meets or exceeds OE specifications (Maximum temperature rating: 350F).
Compared to universal hoses from local auto parts stores, the HPS silicone radiator hose kit has all the correct bends and curves for perfect fitment.
Included in the HPS silicone coolant hose kit are 100% stainless steel non-perforated embossed hose clamps for easy installation, which do not cut through the silicone hoses.
HPS silicone hoses can fix and prevent coolant leaking and engine overheating issues caused by cracked, damaged, or collapsed OEM rubber coolant hoses.
Excellent for extreme ambient and radiant temperature conditions, HPS silicone hoses withstand harsh high temperature and high pressure operating conditions of the engine while maintaining peak efficiency during daily driving or racing competition.
The HPS silicone hose kit is backed by a limited lifetime warranty from HPS Performance Products.
Remark: The silicone hose water permeation rate is 10 to 15 times greater than that of standard EPDM rubber hose.
Regularly checking the water level is highly recommended when silicone coolant hoses are used in a daily driving vehicle.
Fits 2005-2009 Jeep Grand Cherokee 4.7L V8 WK1 / 2006-2009 Jeep Commander 4.7L V8 XK.
