Construction & Design:
The Mishimoto Silicone Coolant Hose Kit is engineered using premium 4-ply silicone reinforced with heat-resistant fibers, ensuring exceptional strength and flexibility. This construction allows the hoses to maintain their shape and integrity under extreme heat and pressure conditions commonly experienced in heavy-duty diesel applications. The internal spring in the lower hose replicates the factory design to prevent hose collapse during high vacuum situations, maintaining consistent coolant flow and system performance.
Each hose is precision-molded to match the exact contours and dimensions of the factory hoses, guaranteeing a seamless fit and easy installation. The smooth silicone surface resists cracking, swelling, and hardening that typically affect rubber hoses over time, providing a longer-lasting, maintenance-free solution.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
