Silicone Radiator Hose Kit 2017 2019 Chevy Duramax L5P Blue

Silicone Radiator Hose Kit 2017 2019 Chevy Duramax L5P Blue replaces factory molded rubber and plastic radiator hoses to reduce failures associated with repeated heat cycles and extended idle time.

This Mishimoto radiator hose kit is designed as a direct, vehicle-specific replacement for the factory Duramax L5P radiator hoses. It addresses the known limitation of the OEM material mix—molded rubber and plastic—that undergoes thousands of heat cycles and long idle periods during typical duty cycles.

Why this matters

Durability under thermal stress: The OEM hoses are described as a mixture of molded rubber and plastic that experience degradation through heat cycling and idle exposure; replacing them with a purpose-built kit reduces the risk of heat-related hose failure that can lead to coolant loss and overheating.

Vehicle-specific fit: The kit is specified for 2017–2019 Chevy Duramax L5P models, matching the intended routing and connections for straightforward installation without modifying factory plumbing.

Brand assurance: Mishimoto is included to highlight the brand and its reputation; this identifies the kit as a purpose-designed aftermarket option from a recognized supplier of cooling components.

Key points

• Direct replacement for factory Duramax L5P radiator hoses (2017–2019).
• Addresses long-term heat-cycle and idle-related degradation associated with OEM molded rubber/plastic construction.
• Offered by Mishimoto, a specialist brand in vehicle cooling solutions.

Installation notes: Intended as a like-for-like service part for maintenance or preventive replacement to maintain coolant system reliability and minimize downtime when operating under sustained load, towing, or extended idle conditions.
