Prepping for an HPDE and catching up deferred maintenance. Fresh coolant, WP, low temp tstat, no apparent issues.

These were my rads yesterday...bottom 2-3" was submersed in soil/sand/compost.

I had cleaned mine last year. When i installed 3rd rad last month, I already had a not insignificant amount of debris starting to collect. That was less than 4k mi.
Clean your rads peeps, cheap easy love for your Carrera!
