If you're a proud owner of a 1989-1998 Nissan 240SX with an LS swap, specifically using the LS3/LS7 water pump and 8 o'clock thermostat paired with a KA24DE radiator, then the HPS Blue Silicone Coolant Hose Kit (Part Number: 57-1991-BLUE) is a must-have upgrade for your ride. This high-performance kit replaces the factory rubber hoses with top-tier silicone, designed to handle the demands of your modified engine.
The HPS silicone hoses are built to last, featuring a 3-ply reinforced design that can withstand temperatures up to 350°F. Unlike standard EPDM rubber hoses, which can degrade over time, silicone has a water permeation rate that is 10 to 15 times greater, ensuring your cooling system remains efficient and leak-free. Regular checks on your coolant levels are recommended, especially if you're using your 240SX as a daily driver.
One 240SX S14 owner mentioned, “After installing the HPS silicone hoses, my cooling system feels more reliable, and I can definitely push my LS engine harder without worrying about overheating.” Another S13 driver noted, “The fit was spot on, and the stainless clamps made installation a breeze. No more worrying about cracked hoses!”
Upgrade your cooling system with the HPS Blue Silicone Coolant Hose Kit and experience the difference in performance and reliability. This is not just a replacement; it’s a solution for serious enthusiasts looking to maximize their Nissan 240SX's potential.
