I think I found the problem

moresmoke · Jul 16, 2022

I bought a loader backhoe 2 years ago. The yard guy at
the dealership mentioned that it would run hot
sometimes. Otherwise it was in good shape so I bought it
anyway. I dont usually run it for very long at one time, so
have not had any issues.

Last weekend, I was working on a bigger project for about
5 hours and it was hot out. Temp gauge started getting
towards the red. So this morning I pulled the front end
apart to clean the coolers/radiator.

This is what all came out. Yes including the cardboard.
Size 12 boot for scale. Gotta wonder about some outfits
maintenance plans.

Ran it for 3 hours this afternoon, and now it struggles to
get up to temperature.

That could have been there way to make it get up to temp instead of installing a correct thermostat

Some engines are hard to get warm. I used to have an 81 f100 that way. 195 degree thermostat and still kept the radiator 3/4 covered. Even 100 degree day's it never even thought about getting hot.

I have had the same problem. With large RV units. They claim it is running hot. Then find out they haven't cleaned the cooling system in years. Radiator clogged up.

Isn t it nice to find something simple like that? This rig must not have been operated and serviced by the owner. Come to think of it I am guilty of not pulling out the cardboard come warm weather. The 1086 overheated one warm spring day and it was then I remembered the cardboard in front of the radiator. Easy fix for something that could have been easily averted.

Last work I did with my Cat 35 before I sold it was disk some river bottom ground for neighbor where DNR was going to plant some trees. It was all growed up in some kind of horse weed that was seeded out. I was pulling my 16 ft. disk in 10th gear idled back. It was no load for that tractor and yet it started running hot. Finally it was in the red zone and tractor shut down. I got looking and all the radiators were plugged with those seeds. I took one of those tall weeds and shook the seeds off to make a 3 foot brush. Cleaned the radiators best I could and tractor started back up and ran cool. Ended up having to clean it 3 times before I was done with the 15 acres.

I have to ask, what was your maintenance plan during the two years since you bought it?

I picked up a low-houred Onan 6 kw air-cooled diesel genset cheap from a local fire dept. It had been installed aboard a rescue truck to power fireground floodlights, but replaced with a water-cooled unit on account of a chronic overheating problem (it would shut itself down with a cylinder head overheat after running a few minutes, even at partial load).

Anyway after removing the cooling blower housing and fanwheel, I discovered a couple shop rags almost completely blocking the inside of the fanwheel. I removed the rags, and put it back together and fired it up. It now runs nice and cool, even at full load. Score!!

When I first saw the photo I was thinking you had found the boot in there too

I have a John Deere lawn mower with a radiator.
I clean the radiator before using it.

My neighbor has a 38 hp John Deere lawn mower.
He cleans his radiator before using it too.

I have to keep an eye on my Farmall C.
I use a cordless leaf blower to clean that radiator..

I use to service/repair the AC's for the local Bota dealer on most all the condenser would be stopped up with trash. On most all they just serviced the tractor and never even looked at the trash in the radiator/condenser. Maybe they made an attempted to blow it out you are not going to do a good job unless you can get a straight shot at it.

I take it you will look a little better on the next tractor. : )

#1 rule coolant absorbs the heat air takes it away... Remember that it will resolve a boat load of heating issues.

I hadnt had any issues with it until now. I use the loader
mostly for moving snow and as a forklift. Not exactly
demanding use.

The front of this machine is pretty tight with all the
coolers and radiator, this stuff wasnt coming out without
disassembling it all. Starting with taking the 1000 lb
counterweight off the front.

Installed a new thermostat this morning, and now the
temp is right where it should be.

Besides the cleaning neglect, somebody neglected to take the cardboard out one spring......used to help the engine warm up in the winter.......I've forgotten that a time or two but the temp gauge on the neglected tractor tells me I forgot something and I remove it when the weather warms up and I start working the machines.

I think I found the problem
