The HPS black high temp 3-ply reinforced silicone heater hose kit (part number 57-1694-BLK) replaces the stock OEM rubber heater coolant hoses for 2010-2024 Toyota 4Runner 4.0L V6 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 heater hose kit has all the correct bends and curves for perfect fitment.
The HPS silicone coolant hose kit includes 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 problems 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 while maintaining peak efficiency during daily driving or racing competition.
The HPS silicone hose kit is backed by HPS Performance Products limited lifetime warranty.
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.
