How to Disconnect EGR on a G20

The Infiniti G20 was last produced for the 2002 model year. The car, like all modern cars, came with an EGR, or Exhaust Gas Recirculation, valve. This valve regulates fuel vapor and keeps your emissions system in check, making the G20 operate more efficiently. If the EGR valve is not functioning, youll need to disconnect it from the G20 so you can replace it with a new one. Do not, under any circumstances, operate the G20 without an EGR valve in place. This can cause engine damage.

Instructions

1

Turn off the G20s engine. Open the hood. Inspect the engine compartment to find the EGR valve. Look next to the large air hose on the left side of the engine. Youll see the EGR valve here. The valve is metal and shaped like a small can. It has a black vacuum hose coming from it as well as an electrical harness.

2

Depress the tab on the electrical harness and pull it away from the EGR valve to disconnect it. Grasp the end of the vacuum hose and gently pull it away from the EGR valve port. You may have to wiggle it a bit. Do not use a tool to remove the vacuum hose; simply use your hands. Using a tool, such as pliers, could damage the hose.

3

Remove the two Phillips screws from the top edge of the EGR valve. Set the screws aside.

4

Remove the two bolts from the side of the EGR valve. Use a ratchet with an extension for leverage. If you have trouble removing the bolts, spray a bit of penetrating solvent on them and let it set for about five minutes. This should help loosen them and make them easier to remove.

5

Pull the EGR valve straight up to remove it from the engine compartment.
