    Stud size for mounting heat exchangers to case

    Anyone know the stud size for mounting heat exchangers to the 2.0L aluminum case? There are two studs (one on each side of the case) to which the exchangers mount, in addition to the exhaust studs. Workshop manual doesn’t seem to show them. I do know the studs are M6 and look to be around 24mm in length, but looking to confirm as the one I have is seriously bent, and is difficult to measure precisely. Also, the single stud I have appears to be fully threaded. Anyone have specs on what’s correct? Thanks.

    Why don't you double nut it and take it out? I think BelMetric gets used for oddball fittings.

    Yeah, I already have the stud removed. I was just wondering if someone has replaced these in the past and could confirm the stud’s length and whether or not the stud is supposed to be fully threaded. I know it’s a minor detail - just curious if someone had replaced one or more of these before and knew exact specs. And yes, Belmetric is a great source for these and other hardware.

    Thanks - I think I had roughly about the same length exposed before I removed it.

    Too paraphrase John Walker just put it in a vise to straighten and measure it.
