2015 F-150 3.5L V6 Engine Guide
The naturally aspirated 3.5L V6 is different from the EcoBoost engine.
Verify the engine identification before purchasing components or following repair guidance.
What to know
Check service history, cold-start and warm idle quality, leaks and any stored misfire codes. A symptom may have several causes.
What I'd check next
For a used truck, compare condition and documentation with the price and intended use.

Official information
Start with the Ford owner manual and Ford's 2015 technical specifications. For recall-related questions, use Ford's VIN recall checker. Published specifications may differ by configuration, market and equipment.
I own a Blue Flame Metallic 2015 Ford F-150 XLT and plan to add firsthand observations, photos and maintenance notes to these guides. I won't present an untested repair as something I've personally done.
