Recipe - Ford 3.5L EcoBoost Gasoline (F-150, Expedition, Transit, Raptor - 2011-present)

Specific Fix build

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

Turbo / boost-control service: boost DTCs (P0236/P0238/P0299 family) first, hardware second. Smoke-test the charge system before condemning a turbo; the wastegate-control solenoid is the cheap culprit behind several code sets. Gen3 Raptor/Tremor P0299 has a TSB (22-2198), and the MY2023 right-hand turbo replacement is a field action (23B65) - check coverage before paying.

Parts

• 3.5L EcoBoost Turbo Control Solenoid, Gen1 (BL3Z-9K378-A) - boost-control solenoid (BL3Z-9K378-A) - cheapest first move on Gen1 (qty 1)
• 3.5L EcoBoost Turbocharger Assy, Gen1 (pair DL3Z-6K682-E / -F) - Gen1 turbo pair member (DL3Z-6K682-E / -F) (qty 1)
• 3.5L EcoBoost Turbocharger Assy, Gen2 std (pair JL3Z-6K682-C / -D) - Gen2 std turbo (JL3Z-6K682-C / -D) (qty 1)
• 3.5L EcoBoost Turbocharger Assy, Gen2 high-output (JL7Z-6K682-A) - Gen2 high-output turbo (JL7Z-6K682-A) - Raptor/Limited (qty 1)
• 3.5L EcoBoost Turbocharger Assy, Gen3 (pair ML3Z-6K682-C / -D) - Gen3 turbo (ML3Z-6K682-C / -D), F-150 2021-2023 (qty 1)

Install order

1. scan boost DTCs; log desired-vs-actual boost under load
2. smoke-test the charge system (pipes, CAC, clamps) and the wastegate actuator circuit
3. replace the boost-control solenoid where the code pattern fits (P0236/P0238/P007D family)
4. on confirmed turbo failure: replace the side, new gaskets and oil-supply check
5. check 23B65 coverage on MY2023 before ordering the right-hand turbo

Expected outcome

Boost restored with the cheapest matching fix; charge-system leaks and solenoid faults are ruled out before a turbo invoice.
