All,

I had just stumbled across the coolant change recommended interval of 2000 hrs OR 2 years in my manual, and saw it mentioned doing a flush? I’d like anyone’s opinion on this with their experience… I’m no professional but I highly doubt that at 2 years old with not even 200 hours on my L2502 that the factory coolant should be degraded enough to flush? If I am mistaken please advise me. Give me your insights on staying with the Kubota coolant or an aftermarket name like the Prestone all makes and models coolant. Thank you all in advance!
