2007 Ford Mustang EGR Valve Parts Q&A

• Q: How to service the EGR Valve on the 4.0L SOHC and 5.4L 4V engines on 2007 Ford Mustang?

  A: The first step to service the EGR system module for 4.0L SOHC and 5.4L 4V engines begins with removing the battery ground cable. The service of the EGR system module begins by first detaching the vacuum tube and electrical connector followed by disconnecting the upper fitting of the EGR system module-to-exhaust manifold tube. During reinstallation tighten the upper fitting of the EGR system module to 39 Nm (29 lb-ft) for 4.6L 3V engines and 42 Nm (31 lb-ft) for 5.4L 4V engines. The replacement of EGR system module necessitates using the proper gasket because variations in orifice dimensions may affect vehicle performance; you should first remove all two bolts and the gasket and module before discarding them. The assembly process requires tightening the bolts to 25 Nm (18 lb-ft). The correct tool for sealing surface cleaning is a plastic scraper because metal scrapers and wire brushes create surface defects that result in leaks. Soft metal surfaces need this careful tooling method. When installing the gasket put it in place with the raised circle positioned toward the opposite direction of the EGR system module.
