Recipe - Ford 3.2L Power Stroke Diesel (Transit 2015-2019)

Specific Fix build

Reliability tier: aggregated - verify before ordering, see /disclosure/

Internal coolant loss diagnosis (SSM 48543: overheat due to coolant loss without an external leak): the EGR cooler and oil cooler share the compact bay - find the path before parts.

Parts

• 3.2L Power Stroke EGR Cooler (CK4Z-9U433-D, current) - the usual internal-loss source (qty 1)
• 3.2L Power Stroke Oil Cooler / Filter Adapter (BK3Z-6881-D, current) - the second suspect in the same bay (qty 1)
• 3.2L Power Stroke Thermostat (XS7Z-8575-A) - ride-along service while open (qty 1)

Install order

1. pressure-test cold/hot; check oil for coolant contamination
2. EGR cooler path first (the documented failure)
3. oil cooler path if the EGR cooler tests clean
4. thermostat and coolant refresh while open

Expected outcome

Coolant loss stopped; overheating resolved.

Parts budget

About $50-$450 in parts. It depends on what the diagnosis finds; each option below is what you buy together.
