I need to add a little bit of antifreeze before winter. I'm afraid of adding the wrong brand or type. What does the Kubota experts here use ? I'd hate to ruin my engine or cooling system.
WFM - seems like there was an extended discussion on antifreeze very recently.
Do a search for "antifreeze," and maybe it will pop up. It wasn't too long ago - maybe going back a few pages on the "Service, Repair" section might show it.
You should look for something suitable for diesels.
The owner's manual for my L3560 says that if the level is low do to evaporation, just add soft water. If due to leakage, add recommended mixture (50/50 soft water and ethylene glycol type for the L3560 engine).
