radiator and after cooler cleaning
Very easy job if you dont mind laying on your valve cover.
Just like all the posts say, 3-4 complete and thorough applications and garden hose sprayer flushes produces a huge amount of material. In my case, I think that I removed 14 years worth of grease and grime roaddirt mixture, well caked on aftercooler and radiator.
The issue here is that your after cooler block access to the forward side of your radiator...solution, use degreaser spray nozzle directed between the aftercooler and radiator, and apply degreaser to aft side of radiator to loosen the debris. FLUSH, FLUSH, AND FLUSH AGAIN AND AGAIN.
The reward, a MUCH cooler running engine, and proper heat transfer thru aftercooler.
Before and after pictures are attached.
Caterpillar wanted to remove the radiator and aftercooler and send to rad. shop for 11 hrs labor. Myself and helper, 3 hrs to clean.
