I just bought a G2000 Kubota tonight with 2000 hours. 60" deck. With the Liquid Cooled 3 Cylinder Engine. It's a pretty clean machine and has all the maintenance records since day one. I got it home and mowed with it , and after 20 min I noticed its getting pretty hot. The gauge says it's running at normal operating temperatures but I feel like it's not reading accurately. When you open the hood you get a waft or hot air. The coolant reservoir is also almost empty which shouldn't help either but the radiator itself is full... Would a really low reservoir really cause the engine to run hotter than normal?

120 degrees feels too hot to touch. 140 will burn you. The engine runs at around 200 degrees, normal operation. So it's going to feel hot. Low reservoir won't generally cause hotter than normal temps. If it did, you'd see it on the temp gauge.

Fair enough. I guess it's just me being paranoid. Before I went to bed last night I was checking it over again. I looked in the fuel tank, and saw that the gas was blue. Never seen blue gas before that hasn't been mixed or 100+ octane. These aren't two stroke engines correct?

Diesel can have that tint to it

Didn't realize they made a gas version. Could be startron or stabil marine fuel stabilizer in it.

The weird thing is , when I started it up I could have sworn it was a diesel. It sounds extremely similar, in a good way . Maybe it's the design idk , but to a blind eye it would be hard to tell a difference

If you buy alcohol free gasoline I have seen it sort of blue(ish). Regular old diesel (at least here in Illinausea) seems to be kind of greenish/yellow Off road would be red

They have a gas engine 3 cyl water cooled that looks exactly like the D782 in the G2160. The give away is spark plug wires :D

it more or less IS a diesel engine but with a different cylinder head, etc. mostly the same block and stuff as the diesel versions (G1900). Good little engines albeit very heavy.

Still use a "version" of it on the ZG332 I think it is, or what is the newest version of that? They had a propane burner too.

Kubota makes a lot of gas engines, all loosely based on their diesel versions but the gas burning counterparts make a little more horsepower than the diesels do. And about the same torque. Look at the graphs, not a huge difference. Hence, I have been saying, use one of those engines on a tractor, the hobby farmers might actually like it.
