About Mishimoto
Mishimoto develops replacement and performance cooling components. Its application-specific silicone kits combine reinforced hose construction with formed connectors and documented clamp limits for the matching factory cooling circuit.
Related Parts
- No internal radiator, thermostat, coolant, reservoir, or auxiliary hose is linked because every cooling component must match the exact Ford model, engine, trim, and routing.

What is the clamp torque limit?The published recommendation is 22 inch-pounds, with a maximum of 27 inch-pounds.
What should be checked after installation?Bleed the system, verify connector engagement and clamp torque, inspect all routing and clearances, and pressure-test for leaks through a complete heat cycle.
Installation Instructions
- Confirm the Ford model, model year, 3.5-liter EcoBoost engine, listed trim, black finish, and Mishimoto MMHOSE-X35T-18BK.
- Allow the engine to cool completely, relieve pressure safely, and drain enough coolant to service the upper and lower hoses.
- Document the factory routing and connector positions, then remove the original hoses without damaging radiator, engine, or reservoir fittings.
- Install the formed hoses and metal connectors in the original routing with no twists, kinks, abrasion points, or contact with heat and moving parts.
- Position the five clamps behind the fitting beads and tighten to 22 inch-pounds without exceeding the 27 inch-pound maximum.
- Refill and bleed the cooling system, pressure-test every connection, verify operating temperature, and recheck clamp position and coolant level after the first heat cycle.
