I had totally rebuilt a 2006 valmet it was bad now what I redesigned was the hyd oil cooler behind the cab. I ripped all that out and put an up right oil cooler and fan combo then installed a manual fan reverser and rad never got dirty. And I noticed that even the new version komatsus still run that shitty cooling system.

It's a valmet and timbco thats when valmet bought timbcos was in 2003 and changed the color over completely in 2004. That noise is an air compressor charging up the reversible fan. Is that at the chehalis auction?
