Under the Hood: 2007 Ford Five Hundred 3.0L

Our featured Under the Hood candidate is a 2007 Ford Five Hundred. The Five Hundred uses a 6 cylinder engine and is a front wheel drive car, so the general layout of the engine components will be similar to most other 6 cylinder, FWD vehicles.

Pictured above is the engine bay of a 2007 Ford Five Hundred with the 3.0L V6 engine.

Thank you so much for taking the time to do this. It's a great help for the less mechanically inclined, like myself.

How do you change the PCV valve??

Davy May 7, 2017 at 2:35 PM  

I have some experience with the PCV valve. It is behind the engine, deep down next to the firewall. It is under 14 - engine manifold. You will need to disassemble that back part of the engine and have a strong wrist as it isn't easy to access. I broke the connector for the valve and struggled for a long time and ended up just taking it to a mechanic who had a much stronger grip and patience than me.
