Too Hot?

[normde2001]

My YM2000B never runs above the 1/4 mark in any ambient temp. or hard use, until the rad begins to become filled with chad. When the temp begins to rise is my cue to stop and brush out the rad with my ever-handy whisk broom. Anything even approaching the 1/2 mark is too hot. If no tstat you need to back-flush the system.

My 2210d will run about 140 with normal use, when I'm tilling with my 5ft tiller or brush hogging it will run between 160-170 max. Never any problems yet.

That's what I see on my 2020D. About 1/4 on the Yanmar Gauge and ~160 on a hot day working hard on my installed gauge.

Thanks for the info, and thanks again to everyone. Everything about the cooling system is essentially brand new, and it ran these temps when I got it from Fredricks. They said they tested it really hard on their dyno when they repaired the head gasket, so I don't know anything to replace on it to cool it down. The radiator is clean as a whistle, so I know a clogged radiator is not the problem. I've read a number of posts here over the past year with folks saying their tractor never gets about the 1/4 mark; this tractor passes that about 3 minutes after starting it.

The temp would be right where the temp probe is in the block or water outlet or whatever it's mounted in.

And like I said my factory yanmar manual on my ym2000 says light on at 212f but again that's a ym2000 not a 2010.

You can add a product called "water wetter" I think it allows less antifreeze to be used (corrosion protection in it, but have to make sure you use enough antifreeze in winter)and allows it to cool better. Racers and hot rod guys use it.

It like $10 or so a bottle. It's not going to make a huge difference but may 5 degrees cooler?? I don't know.

I never got a reading above 155 anywhere on the outside of the block. I don't know how much different it would be on the inside, but after running several hours I'd think it they would be close. The JD tech told me that it was permissible for the outside of the transmission to get to 260 when I was having trouble with it. I had a valve hanging up and I measured 301 beside the pto shaft one day. I completely lost brakes when that happened, and it ruined the fluid. Once I replaced the hyd filter and fluid, it did fine and hasn't done it again. I could easily tell I had a big problem when the tractor got that hot; this tractor doesn't feel hot with the gauge where it is.

I'm thinking that if I just had a light that comes on at 212 I'd think my tractor was doing great.

Clemsonfor mentioned the screen in front of the radiator getting plugged up. That was a problem I had early on. Ever since, I use compressed air to blow the radiator out from the backside and clean the screen after every use. No more overheating from a plugged up radiator screen.

 

[Jtullis13]

Yeah that screen can be a problem.

I overheated the first weekend I had my tractor when I was bushhogging overgrown fields. Found that and haven't don't that again, I stop every so often when cutting when seeds and fluff are present.
