    Just noticed some seepage on passenger side near radiator, from hose between the crimpings. Check the hose on the left, blending in with the background because of how wet and covered it is lol

    I believe this is the the transmission cooler line...correct? 2008 Yukon XL Denali

    YIKES! Is that road salt causing all the rust? it is getting harder by the year to justify living in CA but by the looks of the belts i now have at least one reason, "no rust". It looks like even belts rust! No disrespect intended, the effects of road salt are simply amazing.

    Yes, this truck has been in NY for it's entire 12 year life. The salt is insane and what it will do.
