Mishimoto MMHOSE-F250D-03BL Blue Silicone Hose Kit 2003-04 Ford 6.0L Powerstroke

Vehicle Fitment

• 2003-2004 Ford F-250 Super Duty (6.0L V8 Power Stroke Diesel, 4R100 / TorqShift / S6-650)
• 2003-2004 Ford F-350 Super Duty (6.0L V8 Power Stroke Diesel, 4R100 / TorqShift / S6-650)
• 2003-2004 Ford F-450 Super Duty (6.0L V8 Power Stroke Diesel, 4R100 / TorqShift / S6-650)
• 2003-2004 Ford F-550 Super Duty (6.0L V8 Power Stroke Diesel, 4R100 / TorqShift / S6-650)
• 2003-2005 Ford Excursion (6.0L V8 Power Stroke Diesel, 4R100 / TorqShift)

Fitment Notes

• Fits 2003-2004 Super Duty trucks only - the 2005-2007 6.0L Power Stroke uses a different chassis (mono-beam or twin I-beam) and requires a separate Mishimoto hose kit
• This kit replaces the upper and lower radiator coolant hoses - it does not include the lower overflow hose (MMHOSE-F2D-03EBL available separately)
• Direct OEM replacement fit - no cutting or modification required
• Hose clamps are not included - reuse factory clamps or source separately

Features

• Constructed from high-grade silicone reinforced with four layers of heat-resistant embedded fibers - far more durable than the factory rubber hoses prone to heat cracking and degradation
• Higher pressure and temperature tolerance than stock rubber hoses, addressing a known weak point in the 6.0L Power Stroke's cooling system
• Direct OEM replacement fit ensures a straightforward, bolt-on installation with no cutting or modification needed
• Smooth silicone interior promotes unrestricted coolant flow through the radiator circuit
• Vibrant blue exterior finish adds a clean, finished look to the engine bay
• Compatible with the Mishimoto 6.0L Power Stroke aluminum radiator (MMRAD-F2D-03) for a complete cooling system upgrade
• Backed by Mishimoto's Lifetime Warranty

Product Description

The Mishimoto MMHOSE-F250D-03BL is a direct-fit silicone radiator hose kit engineered specifically for the 2003-2004 Ford 6.0L Power Stroke Super Duty and 2003-2005 Excursion. The 6.0L Power Stroke is well known for its cooling system vulnerabilities, and the factory rubber hoses are among the first components to degrade under the sustained heat and pressure cycles these diesel engines produce. Mishimoto's silicone construction - reinforced with four layers of heat-resistant embedded fibers - delivers significantly higher temperature and pressure tolerance than the OEM rubber hoses, eliminating this potential failure point before it becomes a problem.

These hoses are designed as a direct OEM replacement, retaining factory routing and connection points for a straightforward installation. The smooth silicone interior maintains optimal coolant flow, while the blue exterior adds a clean, purposeful appearance to the engine bay. Hose clamps are not included - the factory clamps can be reused. For a complete cooling upgrade, pair this kit with the Mishimoto 6.0L Power Stroke aluminum radiator (MMRAD-F2D-03). Every Mishimoto hose kit is backed by a Lifetime Warranty.
