    Hello,

    Can anyone please tell me the procedure to remove the exhaust manifold? I have copies of the repair manual, but need help following which steps in which order.

    I'd really appreciate some help. Screwed up the wife's Prius and now I need to fix it.

    What did I do? For the curious I cut the spring bolts between the cat and the manifold not realizing that the nuts on the backside are welded - Doh!! Drilling out the bolts seems impossible - believe me I have tried. So I am resorting to looking at removing the manifold to make a proper repair.

    Thanks
    Sean

    Your in the wrong forum post this in the maintenance and repair forum
    You will get more responses.

    Not sure if I understand is there a nut or a bolt on the manifold side?
    If it's a nut just leave it and drill the nut hole out larger and put a bolt thru and then a nut.
    If it's a bolt that's more difficult I would drive the car to a muffler shop they see this a lot and can heat up the bolt and knock it out.
    You need a pro torch to do this a map gas bottle will not have enough heat.

    I would try anything other than pulling the manifold sometimes that goes really bad and if you snap off a bolt in the block your screwed.

    Yeah I agree. Should still get a replacement spring and bolt, but just put a nut that will fit it on the backside.
