Is it to hot?

[Smoody]

YM2210, cleaned/flushed radiator, new coolant (about 60 water/40coolant)

It is mild here with highs in the 60's, while doing loader work or plowing my temperature is reaching about 210 degrees on my YM2210, I added water wetter in the coolant and staying around 205 degrees with heavy load.

I know that is not considered overheating but is this typical for my machine? I read some ppl on here don't get above 180..should I look into it further or am I safe at 205 degrees? my concern is what will happen when summer hits and it 90's here, what is optimal temperature for the ym2210 under heavy load?

And would a lower water/coolant ratio improve this?

Thanks

Make sure to check the Level in the Radiator after it cooled of an sat. May have Air pockets in it. Warm it up with the cap loose may help also. Also make sure the Gage is good and reading correctly. Use a Thermometer etc. and check the water temp. to the gage reading. And 50/50 mix is what use.

So what temperature are you seeing? I assume by your comment 210 is to hot or indicating a slight cooling issue

 

[careyo63]

Yeah! thats getting up there. No mention of it running hot before. Was that the reason you changed it? The factory light is calibrated or set at 220 I believe thats why I said a possible Air pocket to go that high all the sudden. And on mine I just have the light call me old school but I just stick my hand down below the dash to tell how hot it is Lol.

No, I changed it just because it looked dirty. and it is running same temp before and after. I just haven;t used it much since I bought it and didn't have a numbered guage on my ym2001 so not sure if its good or needs inspecting, lightly using it around the house it stays around 170, but and plowing or loader work it moves up quick, gets to about 205 and holds, used it 2 hrs at that temp yesterday.

I just want it below 200 , just because

Have you cleaned the screen and thoroughly washed out the radiator fins? You may have an airflow issue as opposed to something else. Is the fan in good shape? I'm not worried by something running at 205 degrees by itself, but without a thermostat, that seems a bit high for coolish weather. I'm nervous there may not be enough reserve cooling capacity if it does get warm out to maintain the temperature where it should be.

Clean the radiator fins.

The screen is clean and I sprayed off the fins, but I will double check that, I tightened the belt and the fan is good, I plan to go ahead and back flush one more time after running some cleaner in it, is it necessary to remove the radiator to properly clean all the fins? What is the best way to make sure I get them all clean?

I spoke to a radiator guy who said it was to old to be rodded out?? but that he could boil it to clean, takes 3 days, $85

It has to be an airflow issue like mentioned, as if I throttle down the temperature goes down 10 degrees in no time. I run it at 2000rpm when plowing or moving dirt.

Also how does one go about testing the water pump?

"It has to be an airflow issue like mentioned, as if I throttle down the temperature goes down 10 degrees in no time."

Bingo - lack of heat transfer the core can be plugged in a few tubes and cause this have the rad shop look at it to be sure.

I have an el-cheepo china autogage 1 1/2" 3 gage set up from Oreillys on mine and my highest temp I see in the 100 degree summer when mowing my 2 acre front lawn at the shop is 220.

And it stays put and never pukes coolant out and I know all my system is up to snuff so I wouldn't worry Smoody. My coolant is closer to 70% AF because my freeze protection was 86 below zero when I checked it this winter. fwtw


Fact just for conversation I think the Yanmar light sender is calibrated at 230ish???

I put a white paint mark on the 220 spot so I can monitor it exactly from my seat w/o looking real close its mounted under my dash by my knees.

Once you get over say 250 thats a problem but 220 and down is ok heck most coolant fans on late model cars dont even turn on until 210-225 so I wouldn't sweat it for now its the sudden change that is what we look for.

I don't know of any test for the water pump. I haven't seen output specifications for the pump in any of my service manuals, for any of my tractors, of any brand.

I think cleaning the radiator with soapy water is your best bet. I found a cheap soap nozzle that allows dishwashing detergent to be added to the stream of a garden hose. It works great for cleaning radiators out, because it is low pressure, so the fins won't be deformed. I'm sure compressed air would do fine too, but if it is fairly clean, that should be fine however it gets there.

I would invest in the radiator boil out, honestly, if it consistently starts on run much warmer than 210 consistently. It won't hurt it to run that warm, but much over that creates a risk of localized hot spots that might boil, and that could potentially cause cracks. Especially not knowing the accuracy of the gauge, it would be hard for me to be at the upper edge of comfort long-term. Maybe wait until summer, then see if needs to be boiled or rodded out? I don't know why age would affect the ability to have it rodded, but I'm not a radiator guy. Car Doc may have some information on that for us.
