Manufacturer specifications
Your vehicle’s coolant hoses play a crucial role in the cooling system. Over time, these rubber hoses are exposed to high temperatures, engine heat, and chemicals contribute to the aging process and lead them to develop cracks, leaks, or become soft and mushy. The HPS Silicone Ancillary Bypass Coolant Hose Kit is designed to deliver ultimate durability and resistance to wear and tear for your thermostat bypass, throttle body, air control valve, and oil cooler hoses. These multi-ply reinforced hoses can withstand high temperatures of up to 350F and are less prone to cracking, swelling, or becoming brittle compared to traditional rubber hoses.
In high-performance or racing applications, silicone hoses are often preferred as they are less likely to collapse under suction or burst under pressure, providing better reliability in situations where engine performance is crucial. Engineered using OEM data, these hoses are made to directly fit into your vehicle without the need for any modifications. This kit comes complete with 100% stainless steel hose clamps designed to be safe on silicone hoses and provide a leak-free seal.
