✦
Overview
An owner-operator walking through the full 300-hour service on an RK25, covering coolant flush (including a real-time drain-port clog he works through), dual oil drain plugs, oil filter swap using Shell Rotella 5W40 synthetic diesel, air filter replacement, dust port cleaning, and radiator screen blowout. It's practical and unscripted, with honest observations about fluid condition. Best for RK25 owners approaching a major service interval who want a realistic step-by-step reference.
An owner-operator sharing hands-on maintenance from their own property, with no apparent commercial or dealership affiliation.
