    On my 2nd csf radiator and it's now being warranted out for a replacement
    1st lasted 3 yrs or so..no warranty
    2nd one lasted maybe 15 months (covered warranty) but I don't want to put another junk CSF in. Yes it cools ok...Temps stay around 199 but it develops leaks on the corners consistently. I can't think of putting another one in for my labor alone.

    Mishmoto has one that actually has a built in trans cooler...and being that I tow a toy hauler across country every 3 months for wk I actually like this option.

    Has anyone used the new Mishmoto

    That's wild you're having challenges with the CSF, as they typically do better than the OEM, cooling included. I've used Mishimoto on previous cars and had outstanding success with them. Give them a try and keep your fingers crossed it keeps sealed, just for your past experienc's sake. If this "next" one doesn't hold together, you have to have something causing the leaks as it seems to be leaking from the same lower corners...just spit-balling ideas, but I would have zero issues using Mishimoto's radiator.
