Where is the 3rd cylinder located on a ford 2004 f150?

On a 2004 Ford F-150, the location of the #3 cylinder depends on whether it has a V6 or a V8 engine. Ford offered several engine options that year.

* V6: There's no #3 cylinder in a V6 engine. They have fewer cylinders.

* V8: In a V8 engine, cylinder #3 is on the passenger side (right side), towards the rear of the engine.

To be certain, you'd need to check your vehicle's engine bay and its specific engine type. The engine block usually has markings to identify the cylinder numbers.
