Inspect
If EGR passage indicates excessive build-up of deposits, the passage should be cleaned. Care should be taken to ensure that all loose particles are
completely removed to prevent them from clogging the EGR valve or from being ingested into the engine.
Clean
1. With a wire wheel, buff the exhaust deposits from the mounting surface and around the valve.
2. Look for exhaust deposits in the valve outlet. Remove deposit build-up with a screwdriver.
3. Clean mounting surfaces of intake manifold and valve assembly.
INSTALL OR CONNECT
1. New EGR gasket.
2. EGR valve to manifold.
3. Bolts or nuts.
4. Vacuum tube to valve
