4110 radiators

[kneedeep]

I use a Commercial Coil Cleaner for HVAC units that my friend uses when he services my AC at home. Put in a pump up sprayer and soak it real good and wash out GENTLY from the rear every time I grease the tractor, before And after heavy mowing as well.
Constant maintenance required to keep them clean or have a new radiator built with wider fins.
