A. Okay Joe, here it is:
- Raise vehicle on hoist.
- Disconnect the EGR valve tube from the EGR tube connector at the exhaust manifold. Hold the connector with a wrench while disconnecting to avoid damaging the tube.
- Lower vehicle and disconnect the vacuum hoses from the EGR tube and the EGR valve.
- Remove the two mounting bolts from the EGR valve, and remove the EGR valve and EGR tube as an assembly. Discard the EGR valve gasket.
- If previously separated, connect the EGR tube to the new EGR valve, and finger tighten the EGR nut.
- Install the EGR valve to the engine with a new gasket. Install the two EGR valve mounting bolts, and torque to 15-22 ft lb (20-30 Nm).
- Raise vehicle.
- Install the EGR valve tube into the connector on the exhaust manifold. Torque the line nut to 26-33 ft lb (35-45 Nm), while holding the connector with a wrench to avoid damage to the tube.
- Lower vehicle.
