    The video mentioned just show the way to clean the pipe. How about the ERG itself?

    I believe most people remove the old EGR valve and install a new one.

    How many miles on yours? Had it since new?

    To clean the egr, remove the pipe you cleaned then remove the 2 nuts holding the egr valve to the cooler. I did the cooler at the same time. I had replacements for both from the salvage yard.

    When I removed mine it was at 120 k miles. The valve had carbon deposits which can be removed with a brush and elbow grease :).

    The cooler I have been using compressed air to blow the deposits off of the fins inside the cooler. Still getting deposits out.

    What are the symptoms you are dealing with where you decided to clean the egr valve?

    Keep us posted (y).

    It is a 2 person job:(. But a good excuse to understand toyotas infinite wisdom with the Prius ICE design that includes the egr system:).

    Good luck and PM me if you need any help(y). Getting the new cooler back in is a challenge and I performed a simple modification to help with this:).

    Nope. Just need to separate both ends of the valve. That is 4 nuts (2 on each side of the valve). The nuts on the cooler side are a bit trickier, but can be done.

    Good luck(y).

    EGR's are pretty expensive.

    Unless you go to the salvage yard;).

    $35 for the egr and $65 for the egr cooler at the auto recyclers in Rancho Cordova.

    I drove there to get them, so no shipping and they had plenty of stock:).
