Difficulty of replacement: The difficulty is rated as moderate to somewhat challenging for a DIYer, depending on your mechanical aptitude and experience. It's not a simple bolt-on-and-off job. Here's why:
* Accessibility: Reaching the EGR valve on a Roadmaster can be awkward. You might need to remove some components for better access.
* Vacuum lines: Carefully disconnecting and reconnecting the vacuum lines is crucial. Incorrect reconnection can lead to drivability problems. Labeling them before disconnecting is essential.
* Gaskets: The EGR valve likely has a gasket that seals it to the intake manifold. Replacing this gasket is usually recommended, and it can be delicate.
* Exhaust gas exposure: Be aware of potential exposure to exhaust gases and take necessary safety precautions, including good ventilation.
* Potential for broken bolts: The bolts holding the EGR valve may be corroded, making removal difficult and potentially leading to broken bolts, requiring more involved repairs.
Before attempting the replacement:
* Consult a repair manual: A Haynes or Chilton manual for your specific year and engine will give you detailed diagrams, step-by-step instructions, and torque specifications. This is highly recommended.
* Gather necessary tools: You'll need sockets, wrenches, possibly a breaker bar (for stubborn bolts), and new gaskets.
* Have a clean workspace: This will make the job easier and less prone to problems.
If you're not comfortable working on your car, it's always best to take it to a qualified mechanic. The cost of professional labor might be less than the potential cost of damaging something while attempting the repair yourself if you lack experience.
