1. Remove EGR transducer from air inlet duct.
2. Disconnect vacuum supply tube from [1][2]EGR transducer solenoid.
3. Disconnect electrical connector from solenoid.
4. Remove air inlet duct.
5. Remove EGR tube to EGR valve screws.
6. Remove EGR valve mounting screws. Remove EGR valve and transducer.
7. Clean gasket surfaces. Discard old gaskets. If necessary, clean EGR passages.

INSTALLATION
1. Loosely install EGR valve with new gaskets.
2. Finger tighten EGR tube fasteners.
