Radiator Coolant Silicone Hose Kit for Toyota Tundra (2007-2017) 5.7L

Heavy-Duty Radiator Coolant Silicone Hose Kit for 2007-2017 Toyota Tundra (3UR-FE / XK50)

What it Does: This 3-ply nylon-reinforced silicone radiator hose and clamp kit directly replaces the factory rubber cooling hoses to prevent coolant leaks and blowout under high operating temperatures.

The Stock Tundra Cooling System Vulnerabilities

The factory EPDM rubber radiator hoses on the 3UR-FE engine degrade over time through repeated thermal cycling and exposure to intense engine bay heat. As the OEM rubber ages, it loses elasticity and becomes brittle, leading to micro-cracking at the clamping points and eventual structural failure. Under heavy towing loads, off-road operation, or extended idle periods, localized heat soak accelerates this degradation. This increases the risk of a catastrophic hose blowout, rapid coolant loss, and subsequent engine overheating.

The Engineering Solution

Engineered for high-temperature applications, this replacement hose kit is constructed from premium multi-layer silicone reinforced with 3-ply nylon mesh. Featuring a robust 4.5mm wall thickness, these hoses drastically improve structural integrity and burst resistance over stock. The upgraded silicone compound withstands extreme operating temperatures ranging from -65°F to 500°F, ensuring reliable coolant circulation without the risk of sidewall collapse or expansion under load. With a working pressure of 85 PSI and a peak burst pressure rating of 245 PSI, this system is highly resistant to UV rays, water, ozone, and oxygen degradation. A comprehensive heavy-duty clamp kit is included to ensure a secure, uniform 360-degree seal across all connection points.
