INSTALLATION
1. Install the 2 bolts to the lower EGR tube to EGR valve. Tighten the inboard screw to torque and snug the outboard screw. Locate the tube in the approximate location needed for assembly. This will allow the movement of the tube into position when install on the vehicle. Tighten the EGR tube inboard screw to 11 Nm (95 in. lbs.) torque.
2. Install new gasket for the EGR valve to cylinder head and loosely install bolts.
3. Install assembly.
4. Loose install the 2 bolts for the EGR valve to cylinder head to cylinder head.
5. Loose install the 2 bolts and gasket for the upper EGR Tube to EGR valve.
6. Raise vehicle and support.
7. Rotate tube into position.
8. Install new gasket between the exhaust manifold and tube and loosely install bolts.
9. Tighten the EGR tube to exhaust manifold bolts to 31 Nm (275 in. lbs.) torque.
10. Lower vehicle.
11. Tighten the EGR valve to cylinder head bolts to 23 Nm (203 in. lbs.) torque.
12. Tighten the EGR tube outboard screw to 11 Nm (95 in. lbs.) torque.
13. Tighten the upper EGR tube screws to EGR valve to 11 Nm (95 in. lbs.) torque.
14. Tighten the upper EGR tube to intake manifold to 11 Nm (95 in. lbs.) torque.
15. Connect the electrical connector to the EGR valve.
