LSDZWORK Engine Heater Hose Inlet & Outlet Assembly for Ford F-150 5.0L (2015–2017) — OEM Fit, High-Temp Rubber

LSDZWORK Engine Heater Hose Inlet & Outlet Assembly FL3Z-18472-K is a complete HVAC coolant hose kit designed to replace worn or leaking inlet and outlet hoses on 2015–2017 Ford F-150 5.0L engines.

This replacement assembly gives you a ready-to-install solution for heater coolant routing, combining high-temperature rubber hoses, OEM-compatible quick-disconnect fittings, and reusable clamp-style connections. It directly replaces several factory part numbers (including FL3Z-18472-K, 626-802, and KH874) and is intended to restore reliable coolant flow to the heater core and related circuits without the need to buy an entire factory assembly.

How does this assembly match factory specifications?

The LSDZWORK kit is engineered to align with the dimensions, connection types, and routing used on the original Ford F-150 5.0L components. Materials and fittings are selected to function like OEM parts while offering repair-friendly improvements.

• Direct fit for 2015–2017 Ford F-150 5.0L applications.
• Replaces FL3Z-18472-K, FL3Z-18472-G/H, 626-802, 160553, KH874.
• Includes quick-disconnect fittings compatible with factory ports.
• Hose lengths and bends mirror OEM routing for straightforward installation.

What materials and durability features are included?

Hoses are formed from high-temperature resistant rubber with smooth internal passages to reduce turbulence and wear. Sealing surfaces and clamps are designed to resist coolant degradation and provide long-term pressure retention.

• High-temperature rubber that resists heat and coolant exposure.
• Smooth internal channels to maintain steady coolant flow.
• Robust sealing for reliable leak prevention under operating pressure.
• Reusable clamped connections to enable targeted repairs.

How does installation compare to replacing the full OEM part?

Installation follows the same basic steps as the factory assembly but is simplified by repairable clamp fittings that let you replace only the failed section. The kit is intended for do-it-yourself mechanics and professional shops alike.

• Comes as a complete heater hose assembly for quick swap-out.
• Repairable clamp connections avoid replacing the whole assembly for minor leaks.
• Fits factory connection points and reuses standard quick-disconnects.
• Installation time similar to OEM replacement; basic hand tools required.

Will this kit help prevent future coolant leaks?

While no part can guarantee indefinite leak prevention, the LSDZWORK assembly improves longevity by using heat-resistant materials and upgradeable clamped joints. Proper installation and periodic inspection further reduce the chance of recurrence.

• High-quality rubber resists cracking from heat and age.
• Clamped joints allow replacement of only worn segments.
• OEM-matching connectors minimize stress at attachment points.
• Routine checks and maintenance extend service life.

Who is this for? This LSDZWORK heater hose inlet & outlet assembly is for Ford F-150 5.0L owners (model years 2015–2017), independent mechanics, and repair shops seeking a cost-effective, OEM-compatible replacement. It suits drivers who want a durable, serviceable alternative to factory parts—especially those who prefer to perform repairs themselves or keep repair options open by using clamp connections for partial future fixes.
