Show original supplier description
The HPS Silicone Heater Coolant Hose Kit (part number 57-1435) offers a high-heat resistance upgrade for the 2003-2006 Nissan 350Z 3.5L V6 Left Hand Drive. Engineered to replace stock OEM rubber heater coolant hoses, this kit is constructed from high-temperature, 3-ply reinforced silicone material, capable of withstanding up to 350F. This kit includes HPS Performance Reinforced Silicone Hoses and 100% stainless steel non-perforated embossed hose clamps for straightforward installation. The premium grade silicone hoses are designed with correct bends and curves to ensure a perfect fitment, preventing and fixing coolant leaks and engine overheating issues caused by cracked or damaged OEM hoses. It is important to note that silicone hoses have a higher water permeation rate than standard EPDM rubber hoses. Therefore, checking the coolant level regularly is highly recommended when using silicone coolant hoses in a daily driving vehicle. The kit comes with a 2-year warranty and is available in Black, Blue, and Red.
