Hey, guys. I have a bunch of equipment maintenance to do this fall, and I'm going to start stocking up on fluids and filters. I've been using Peak Final Charge Global in my Kubota M7060 and two RTV-X900s. I do a radiator drain-and-fill every 2 years. I've never done an actual flush.
When I started checking prices and looking up products, I noticed that Final Charge Global isn't being stocked by Wal-Mart or any of the usual auto parts stores in my area. I started reading up, and it seems Global is being phased out in favor of Pro-Series. I can still buy the Global Concentrate on Amazon for a reasonable price, but I'm not sure if I should just go ahead and make the switch to Pro-Series.
I've pulled up the spec sheets on both coolants, and both products claim to be compatible with ALL heavy-duty diesel, gasoline, and natural gas engines. Global explicitly claims to be Kubota compatible while Pro-Series does not. Global is nitrate-, phosphate-, silicate-, borate-, and 2-EHA-free. Pro-Series only claims to be nitrate-, and 2-EHA-free. However, I've read that phosphated coolants tend to be desirable for Asian engines, as long as they aren't mixed with hard water. On the other hand, I've read that silicates can cause problems due to deposits and scaling, and that Asian manufactures tend to recommend against them.
I've gone through previous threads on Kubota coolants, here and on other forums. The consensus seems to be that they aren't too picky. They don't have sleeves or use unusual metals or seals. Kubota gives very vague coolant recommendations. "Ethylene Glycol Long-Life Coolant" is about the jist of it. So, what do you guys think? Should I buy some Global concentrate online, or just switch over to Pro-Series, which I can pick up at local retailers? Which do you guys think would be better? If I switch to Pro-Series, is it fine to do another drain-and-fill, or do I really need to perform a flush?
