Once you have opened your hood, use your 10 mm wrench (or 10mm socket) to disconnect the negative lead from your battery terminal. This will ensure that no electrical damage will occur during the removal and replacement of your valve.
If you forget to remove the lead from your battery terminal, there is a chance of electrical damage to the car and to you!

Step 3

Remove the intake line by loosening the screw in the clamp that holds the intake line near the air-box.
Remove the fuel solenoid from the bracket in the top of the intake line and set it aside. This is so that you can fully remove the intake line and have enough room to pull the old EGR valve out.
On the side of the intake line you will find another small hose. Gently remove it and set it aside.
Be careful! When removing the hose from the side of your intake line, you could easily crack or damage the hole it fits into. Make sure to be extremely gentle during removal!

Step 6

There are 2, 12 mm bolts located on the bottom of the valve. You can loosen them using either your 12mm wrench or socket depending on what is easier for you. Once you have completely loosened the bolts set them aside and pull your old valve out.
There should be a gasket located between the valve seat and valve face and it is very easy to drop! Make sure you have a hold of it when pulling out your valve.

Don’t forget to place your new gasket between the valve seat and face before tightening down your new valve.
