COOLER-EGR
DESCRIPTION
The EGR cooler (7) cools recirculated exhaust gasses to reduce combustion temperature and a greater mass of exhaust gases can thus be circulated. There is less nitrogen oxides as a result.
The EGR cooler (7) allows the engine and catalytic converter to reach their operating temperature quickly.
REMOVAL
1. Remove engine cover (Refer to 9 - ENGINE - REMOVAL).
2. Drain cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE).
3. Remove EGR cooler coolant hoses (8).
4. Remove EGR cooler to exhaust manifold tube (11).
5. Remove EGR cooler to EGR valve tube (1).
6. Remove EGR cooler mounting nuts (6).
7. Remove EGR cooler (7).
8. Remove the bypass valve mounting screws (3).
9. Separate the bypass valve assembly from the EGR cooler body (5).
INSTALLATION
1. Using a new gasket, position the bypass valve assembly to the EGR cooler body (5). Tighten screws to 10 N·m (88 in. lbs.).
