I have let it run at least twice that long after filling and never been able to get any more coolant in. I'm pretty convinced now that it is probably the radiator, but I sure don't want to go back in there and replace it right now, especially since I've never had any overheating issues. I think...

Each time I have drained the system I did it just as described in the manual. Open the drain valve on the bottom of the radiator and remove the radiator cap. I have done it both with the rear wheels elevated and with all four wheels on the ground. Neither the owners manual or the service manual...

Well I'm still stumped. I took out the thermostat to drill that hole only to discover it already has one. Then I looked at the parts diagram on Messicks and you can see the same hole, so using that as a way to bleed air seems to be the design. But I'm still left with the question of why I can...

Thanks for the tip about the vent hose. In the thread you linked, others with a 2006 RTV900 said they don't have one as described, but I'll take a look anyway. I did try running it with the front wheels elevated and the radiator cap off and I was not able to get any more coolant in. I called the...

There is no problem with a hole in the thermostat? Does this just mean that a small amount of coolant goes back to the radiator even when the engine is not hot?

I hadn't even thought of air trapped in the system (shows how much experience I have with engines). I actually elevated the rear wheels when draining coolant to help it all drain out, and I left it that way when filling. D'oh! I did then re-check the coolant level after putting the rear wheels...

I followed this advice yesterday. When the water first ran out of the engine block it was kind of rusty but not nearly as bad as I thought it would be. I let it run clear and then took the hose to the radiator again. After getting everything put back together it still only took about a...

I got it fixed - it was the gauge. I bought a copy of the service manual and followed it's diagnostics. I used a multi-meter to check the resistivity of the sensor and it returned values that made sense. I got a voltage reading from the lead to the sensor, but it was less than 1V, and the manual...

Thanks for the info - I'll give this a try in the next couple days when i get a chance.

The old plug looked surprisingly good once I got it out - no rust or pitting that I could see.

I was doing a radiator flush and as I was warming the engine up I realized the temperature gauge wasn't moving at all. I haven't had this RTV very long. I have never seen it over heat but just hadn't realized that the gauge apparently does not work at all. When the headlights are turned on the...

fixed it Just in case anyone was interested, I fixed it and it was pretty easy. I got the plug from the local Kubota dealer. After removing the starter motor I used a mallet and blunt piece of metal to tap one edge of the old plug. This made the opposite edge come forward until I could grab it...

Did you get replacements from Kubota? Some folks seem to prefer brass plugs and I thought I might look for those and replace the one right beside it at the same time. I got the Service Manual for the RTV900 but I can't seem to find an engine diagram with part numbers, so it's difficult to go...

Thanks for the help Thanks for the replies. I am also afraid that this may be the start of many problems. The machine has low hours but some of the corrosion is significant. I've been watching a few videos and it seems like it is worthwhile to try to replace that plug myself. It looks pretty...

I recently bought a used Kubota RTV900 with a plow attachment to take care of a long, steep driveway this winter. I think it’s a 2006 and it has about 460 hours on it. The previous owner told me when I bought it that it needed an oil change but I know nothing else about how well it was...
