94-03 Ford 7.3L Powerstroke Diesel Oil Filter Adaptor Housing

Description
Warranty Information

Restore the oil cooler assembly on your 7.3L Powerstroke Diesel with this direct-fit replacement rear oil cooler housing and oil filter adapter. Designed for 1994–2003 Ford 7.3L Powerstroke Diesel applications, this housing replaces the original oil filter-end oil cooler header, providing a reliable repair option for damaged, corroded, cracked, or leaking factory components.

The 7.3L Powerstroke Diesel uses an engine-mounted oil cooler assembly with separate front and rear housings. The rear housing serves as the mounting point for the spin-on engine oil filter and connects to the oil cooler core, making it an important component of the engine's lubrication and cooling systems.

Over time, the original housing can suffer from corrosion, damaged sealing surfaces, stripped threads, or physical damage during oil cooler service. Replacing a compromised housing helps restore proper sealing and eliminates the need to reuse a damaged original component during an oil cooler rebuild.

Manufactured as an OE-style replacement, this housing is designed to match the mounting configuration and function of the original Ford oil filter adapter.
