YM3110D Overheating - Time for new radiator?

[drunderw]

Good evening everyone,

I've had an issue with my YM3110D overheating the past few times I've used it to cut the fields. I'm running through stuff less than a foot high running at 2000 RPMs and after about 20-30min I start hitting up near 215 on my temperature gauge. For my gauge I replaced the stock one with an actual gauge from Hoye. I've flushed the radiator (at time time very brown) and am running 50/50 mix and the front of the radiator is clean as I've pulled the screen and made sure it's clean each time. If I shut off the PTO and let it sit at 2000 RPM the temp will come down to 190 but I can get to working again and after about 10 minutes I'm back at 215. It really makes getting work done hard having to stop. Sometimes I can go longer but I'm having to constantly watch the gauge and stop and let it cool down so I don't go too hot. Is it time to buy a new radiator? If so I'm planning to order and install the new one this weekend. The ragweed around here will start blooming soon and I've got a bunch of the field uncut because I can't get into it without the tractor overheating. We've got some pretty nasty allergies so I'm wanting to knock that out.

Thanks for the thoughts!

David

Have you tried spraying water through the radiator core in the opposite direction as the air is pulled through the radiator. Remove the screen and take a spray nozzle and flush from the non screen side. It is sometimes surprising how much stuff comes out.

Watch your overflow bottle and see how hot it's showing. If it's not changing you may have a gauge problem still? Doubtful but check the sensor is clean. Also you can rent or borrow a pressure tester from most any big chain auto parts store. Then you pretty much rule out the head gasket pressuring up the Sys.. My guess is the Radiator still needs a good flushing. May be worth taking the Radiator to a shop and have them go through it.

Thanks. I replaced the head gasket April 2017 due to a faulty temp warning light and it running hot and blowing coolant out of the bottle and steaming. That may have damaged the radiator when it did that, but I never knew how often it ran hot before that since I'd only had it a couple months prior. I haven't run water through in the opposite direction through the fins so I need to try that. The new radiator is like $300 so unless someone working on it would be cheap I'd probably just get a new one - I have no idea how much that would cost - I may call some local shops to see.

Everytime I do that I'm amazed at how much dirt comes out the front of the radiator. Don't use a power washer, just a garden hose and use a real soft brush to get some dish soap into the fin area. It always makes me feel real good when I clean the radiator that way....don't know if I've ever seen a difference in temperature though...

Worst case check Charlotte area. There be someone who will do it. Depending how bad it is will reflect the price. As you described I don't think it's that bad. Clemsonfor a member on here is in Greenwood been to the my house before. Great guy! He'll most likely know someone local to you. If he don't I'll ask some relatives in Mooresville. Big in racing there know.

i was going to say a radiator shop. They will be less than $100 they do what you call rodding it out. They will make it like a new one. But usually when this is effective the radiator is so crudded up you can see it by just looking inside the tanks and see the crud. It works. I don't personally know one in the charlotte area, but there usually in the downtowns in the automotive districts and the older suburb areas. In that area there will be plenty with the motor sports in that area. The dirt track guys will know who to use. Look up in the yellow pages or google. These places are a dying breed usually and don't have fancy websites usually so when google does not turn up anything don't worry to much. You can go to your good local parts place...not really advance or auto zone (you never know who your talking to at those places), but like a Napa or CARQUEST and find the older guy who knows all the places around you and ask where the radiator shop is.

Did you pressure test the head? Are you sure its sealed up tight? I'm not saying you cant blow out a radiator with a bad head, i have never seen it, but i also am no expert. But the radiator cap only allows pressurization within safe limits of the system/radiator, anythi9ng beyond the caps limits just blows out into the overflow bottle and if that fills up just blows onto the ground.

oh your not in charlotte, it says Greenville area. My Late father in law use to have a shop there. I personally have carried a few radiators to be fixed and picked up a few in the Greenville area. There was a shop in what they call the Berea area. It was right next to the ...oh heck whats that greasy dinner we use to eat lunch at? I will have to look it up, not sure if it even was open anymore. His shop price i think was like $60 or 75 to "rodd" one out. If your not from around here or don't know what there saying it sometimes sounds like the say "rotting one out". haha

My YM2000 overheated when I ran it hard until I pulled the radiator and had it flushed at a local radiator shop.

That was much cheaper than a new radiator.

I also replaced all the old hoses while they were easy to access with the radiator removed.

not many (if any) radiator shops left around me. only does large trucks, or heavy equipment.
With all these new radiators now being made with mostly plastic and aluminum for vehicles, most radiator shops have gone out of business
