EGR Filter Replacement
EGR FILTER REPLACEMENT
The IEEGR (Integrated Electronic Exhaust Gas Recirculation) valve has a serviceable filter next to the vacuum tube that provides clean fresh air to the
regulator.
1.
Remove filter cover. Use extreme care to avoid breaking the electronic EGR cover and dislodging the vacuum regulator. This cover can best be
removed by prying each segment from the locking lip and gently rocking to remove.
2.
Remove EGR filter.
3.
Install new EGR filter.
EGR INTAKE PASSAGE CLEANING
When cleaning intake manifold EGR passages, 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.
1.
Disconnect the vacuum hose from EGR valve and remove the valve.
2.
Remove deposits from EGR ports by hand using suitable tools.
3.
Brush small deposits down EGR port into passages, then using compressed air, blow ports clean. Solvents should not be used to clean EGR valve
or passages, since damage to the system may result.
4.
Install EGR valve, using new gasket
EGR VALVE CLEANING
CAUTION: Do Not wash any EGR valve in solvents or degreasers, as permanent damage may result. Also, sand blasting of the valve is not
recommended, since this can affect the operation of the valve. Wear approved eye protection for this cleaning procedure, to avoid possible
injury to the eyes.
Use the following cleaning instructions for EGR valves.
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 buildup with a screwdriver.
3.
Clean mounting surfaces of intake manifold and valve assembly.
4.
Install valve assembly using new gasket.
EVAPORTIVE CANISTER FILTER REPLACEMENT
Every 24 months or 30,000 miles, the filter on an open bottom canister should be replaced.
1.
Remove all hoses from the top of the canister and mark. Remove the canister.
2.
Remove the filter element by squeezing it out from under the lip surface at bottom of canister and from under retainer bar, where used.
