Valve Spring Squareness

WARNING: This page is about a different car, the 2014 Lincoln MKX and 2014 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.

Measure the out-of-square on each valve spring.
- Turn the valve spring and observe the space between the top of the valve spring and the square. Install a new valve spring if out of square.
- For additional information, refer to the SPECIFICATION chart in the appropriate Engine article.
- If out of specification, install new components as necessary. Refer to the appropriate Engine article for the procedure.
