    Hi,

    I have a Cummins 6CTA8.3, we just removed the standard Cummins wet elbow from the turbo and the bolts were very badly rusted, and stuck in the housing.

    What type of bolts would you recommend to use? And also Nickel anti seize, copper anti seize?

    Much appreciated.

    Rick.

    Thanks Rob,

    Also, My engine is the older 6CTA 8.3 M2 with Denso pump, will the new after coolers you supply fit that model ok? They appear to be the same.

    Grade 10.9 shoulder bolts: https://www.sbmar.com/product/cummins-marine-turbo-exhaust-bolt-washer-kit/

    All of the usual anti-seize products should be rated for 1,600F and above
