  • [Corsa C 2000-2006] tutorial on replacing EGR valve

    hi,

    i've had an emissions light on my display for a month or so, and i am convinced the egr valve needs cleaning or replacing.

    Is there a tutorial on how to remove and refit an EGR valve on a corsa c 1.0.

    cheers

    It's all in the Haynes but pretty self-explanatory. You need to release and block the coolant pipe (you won't lose much but refill very very slowly as they love to airlock and there's no bleed).

    Remove the loom connection.

    Remove the pipe running from the back of the EGR to the inlet manifold - this is fun as sockets won't fit onto both bolts. They are torx bolts I use a normal rachet spanner (8mm or 10mm) - can't remember which off the top of my head.

    Undo the bolts holding the EGr to the head.

    Clean with carb cleaner.

    You need a new gasket to refit - make sure you get the right one for your engine as the X & Z series engines use different porting and so different gaskets.
