How to Change a Chrysler EGR Valve

The EGR valve on your Chrysler vehicle is an important part of the emission control system, and replacing a bad valve is an easy process. Keep in mind that on some Chrysler vehicles you need to change the EGR valve and transducer as a single assembly. Consult your car owner's manual or local dealer for more information, if necessary. However, whatever your model, follow these simple steps to change the EGR valve in a matter of minutes.

Things You'll Need

  • Wrench set Adjustable wrench Ratchet and socket Plastic scraper New EGR valve gasket
  • Locate the EGR valve to one side of the engine, near the valve cover. Most EGR valves resemble flat, metallic mushrooms 2 to 3 inches in diameter, and have a pipe or tube connected between the exhaust system and the valve. On some models, the valve might be hiding underneath the electric EGR transducer.

  • Remove the vacuum hose. Depending on your particular model, this hose might be connected to the EGR valve. If the valve and transducer are part of a single assembly, the hose might be connected only to the transducer. Carefully remove the hose with your hands.

  • Unplug the electrical connector from the EGR assembly if you need to remove the valve and transducer as a single unit.

  • Disconnect the nut connecting the tube to the EGR valve using a wrench or adjustable wrench; then remove the two valve mounting bolts using a wrench or ratchet and socket. Remove the valve or valve assembly from the engine compartment and discard the EGR valve gasket.

  • Clean the gasket sealing surface on the engine using a plastic scraper to avoid damage to the surface. Using a new gasket, install the new EGR valve on the engine cylinder head and drive in the two mounting bolts by hand first, then screw the tube to the EGR valve by hand to avoid damage to the threads. Tighten the two mounting bolts and the tube nut.

  • Plug the electrical connector and vacuum hose or hoses to the EGR valve assembly.
