TORQUE
Scheme 3
| WARNING | The normal operating temperature of the exhaust gas recirculate (EGR) valve and tube is very high. Therefore, never work around or attempt to service any engine component until it is completely cooled. |
- Remove lower EGR tube nut (3) from exhaust manifold.
- Remove lower EGR tube bolts (1) from EGR valve (5).
- Remove gasket (4) from EGR valve (5). Clean gasket surfaces on EGR valve.
- Remove lower EGR tube (2) from vehicle.
Scheme 4
| WARNING | The normal operating temperature of the exhaust gas recirculate (EGR) valve and tube is very high. Therefore, never work around or attempt to service any engine component until it is completely cooled. |
- Disconnect negative battery cable.
- Remove upper bolts (1) from intake manifold. Inspect gasket, replace if necessary.
- Remove bolts (5) attaching upper tube (2) to EGR valve (3).
- Remove the gasket (4) between upper tube (2) and EGR valve (3). CAUTION: Clean mounting surface of EGR valve. Do not use sharp metal scraping tools. Damage may occur to the sealing surfaces of the EGR valve causing a leak.
- Clean mounting surface of EGR valve.
Scheme 5
| WARNING | The normal operating temperature of the exhaust gas recirculate (EGR) valve and tube is very high. Therefore, never work around or attempt to service any engine component until it is completely cooled. |
Scheme 6
- Remove two upper tube mounting bolts.
- When removing EGR tube assembly be careful not to drop the silicone rubber seals into the intake manifold. Clean gasket surfaces on the EGR valve. Note that any loose dirt can lodge between the pintle and the seat and cause valve leakage that will give a rough idle and depressed manifold vacuum.
- Remove two lower tube mounting bolts.
- Remove tube assembly from vehicle.
