I don't know either...but it seems Kubota thought so since they're replacing the radiator.
Carolyn, when the tractor is returned, open the hood and look over the radiator area. You should be able to tell if it is, in fact, a new radiator.
Good luck to you!

I am not sure what state you reside in, but would suggest that you start writing down everything that has taken place with the purchase. Also get the names of the people you speak with so it isn't a situation of you saying "they" said, but rather "JIM" said.
Every state has Lemon Laws so find out what your state law is. I wuld think that if they have made many changes and still have a problem with a brand new item then you have a case to either get your money back or a replacement.
Just my two cents...............

In my opinion, EXCEPT for the remark about not using the tractor when it's hot out
(that was a really stupid thing to say) I would say the dealer is doing everything they should. These are mechanical devices, things go wrong and sometimes are wrong from the factory. They replaced the the thing that was most likely to be the problem. They sound to me like they are trying to make it right. Now if it overheats again and they say that there is nothing that they can do, THEN is the time to get upset. Now don't get me wrong I would be aggravated that my new tractor is in the shop three times so soon, but while one mechanic was busy running his/her mouth to you it sounds like another might have been trying to figure out your problem.
I hope they get your problem fixed and that is the last one you have with your new tractor.
P.S. Do you live in a live volcano?
Because then it might get too hot out to mow.

Is 202 overheating? I use my Kubota when the ambient temp is 100. Does another 100 degrees really mean overheating?
The temp guage on my tractor rarely climbs of the peg by more than a few mms even when it is 95 outside. Even when the radiator is clogged with dust on a hot day the temp guage doesn't get to halfway. (But that's when I stop and clean it out anyway. I know the temp guage says nothing about actual temp in degrees.
I do have an infrared thermometer. I'm curious about this. Where do you point it to determine engine temp? On the valve cover? At the block? Where on the block?

202 is not overheating IMO. If I am traveling up the mountain in my dump truck with a load my temps can get close to 230. Most new car thermostats do not even open until 190. I run my L48, KX161 and bobcat 863 in the heat all day and they all run around 190-200 average with it being about 95 outside but they do not run much cooler if it is 70 outside.
I would agree that the mech said a stupid thing but I would let him know very politely that you know 200 +- 10 is normal. Motor manufacturers do not make it that close in temps otherwise none of us would be able to use our tractors until winter.
Average overheating temps are around 250-260. Remember water must boil for overheating to take place and water boils at 212 sea level. and when it is in a contained system it can go higher before it boils.
It sounds to me that their is restrictions in the system somewhere.

Everyone---the dealer is suppose to return my tractor on saturday. They say it is working but now wish to try it on my hills. I hope it works but I also hope that if there is a problem it shows up then.

Not all thermostats open at 190. My L opens at 160. I bet most others do to. I fixed my overheating problem (a bad NEW thermostat), it stick on 160 all day. It did run up to 175 the other weekend when I was clearing those trails, there was some stuff on the screen. I got most of it off in the field and the temp immedialtly dropped back to 160. I used the compressor when I got back to the house.
Good Luck,

I wouldn't call 202 overheating. Remember with tighter emission standards being mandated by the feds, even on tractors, thermostat ratings and running temps are going up.
Cars used to come with 160-180 degree thermostats and now all of them have 192 or higher in them. They say it makes a more complete burn.
A lot of diesel truck owners have gone up to a 202 deg thermostat because supposedly that is the most efficient temperature for them to run at. I'm still debating that one but its not going to hurt it. Too cold certainly will though. I wouldn't recommend pulling hard on any engine untill it's at least up to 160. Back when tractors had shutters instead of thermostats it wasn't uncommon on the hard working ones to replace the rings after every season or two. My old farmall is a perfect example. I have a C model without a water pump or thermostat that never comes off the cold mark and I replaced the rings once a year for it's last owner. He worked the tar out of it. My super C has a water pump and thermostat (originally 165 degree but now 180) and I have only rebuilt it once so far. It has several thousand hours on it now.
I would be willing to bet you have a gauge problem. I was a Kubota mechanic for quite some time and we could have 20 of the exact same tractor on the lot but not a single one of them would have the same reading on the gauge as the next. With electronic clusters there is always a varience between different machines. Some say low some high and some just right. 202 with a digital thermometer anywhere on the engine block is definitly not bad. On the outlet end of the radiator it would be a problem but not on the block. Just for grins I went out and checked around my new tractor with the laser thermometer and the only place that was under 202 was near the injector pump and the water pump. Most of it was around 210 -220. The turbo was way higher than that on the turbine end and colder on the compressor end.
I think the mechanic was just having a bad day myself. I've operated tractors all the way down below zero, WAY below zero, and above 140 ambient temps and the only ones that truly overheat had a problem that was pretty obvious.
As for the hydraulic leaks that's pretty common. Within the first 10 hours on my new one (not a Kubota) I had to tighten a few hydraulic lines, both suction and discharge lines on the AC compressor, a power steering hose and a couple fittings on the Injector pump. It was a few ounces low on freon too. It took me about 30 minutes to tighten it all up and add some 134 to the system. The problem with that stuff is AC fittings especially, Hydraulics to a lesser extent, should be put together with lubricated O rings but they never are. Everything is assembled dry at the factory. I could not even begin to count the number of AC leaks I've fixed on new cars or compressors I've had to rebuild or rack and pinions I've had to reseal. I used to really hate that stuff. Warranty work doesn't pay for squat. That's why I don't work for dealerships anymore. I work for myself and only work on tractors or vehicles that are ones I like. Kubota has always been one of the best brands of tractors out there. They had by far the fewest problems of any brand I worked on when new but a few small leaks can probably be expected.
