Show original supplier description
The HPS Performance Silicone Heater Coolant Hose Kit (57-1422) is engineered as a direct replacement or upgrade for the stock OEM rubber heater coolant hoses on the 1986-1992 Mazda RX7 FC3S Turbo Left Hand Drive. Constructed from high-temperature, 3-ply reinforced silicone, this kit is designed to withstand extreme temperatures of up to 350F, ensuring reliable performance and longevity in demanding conditions. The hoses feature correct bends and curves for a perfect fitment, making installation straightforward. Included are 100% stainless steel non-perforated embossed hose clamps, which are designed to prevent damage to the silicone hoses during installation. It is important to note that silicone hoses have a higher water permeation rate compared to standard EPDM rubber. Therefore, checking the coolant level regularly is highly recommended when this kit is used in a daily driving vehicle. The kit is backed by a 2-year warranty.
