EXHAUST GAS RECIRCULATION (EGR) SYSTEM CLEANING
CAUTION: Avoid breathing fumes and swallowing EGR exhaust deposits when removing components for cleaning as bodily injury may result.
IMPORTANT: Whenever the exhaust gas recirculation (EGR) valve is removed the EGR system should be inspected and cleaned if needed. This will ensure that the EGR system will function properly under all operating conditions.
Proper EGR system service consists of the following steps:
1. Remove, clean and inspect the EGR pipe.
2. Remove, clean and inspect the EGR valve.
3. The EGR valve can be inspected for deposits and cleaned using the following procedure:
1. While holding the EGR valve base in your hand, try to rotate the connector housing. Replace the valve that exhibits looseness.
2. Inspect the EGR valve pintle and seat for deposits. Use a cloth or other suitable soft device to remove deposits. Remove all loose particles. If deposits are such that pintle/base interface cannot be cleaned adequately to allow the pintle to seal against the seat, replace the valve. Damage to the EGR valve base will occur if cleaned with solvents, sharp tools, wire brush, wheel or sand blasting. Cleaning by these methods is not recommended.
4. Install the EGR valve.
5. Install the EGR pipe.
