I suspect that on a machine as small as yours the only way to adequately clean the cooling package might be to remove it and split all the coolers apart from one another. What you find may surprise you.

Oh I’m sure it’s a disaster in between everything.

One thing I learned from on of the better mechanics on here when my Tak TB260 kept creeping up in temp was to make sure the fan belt was tight enough to not slip at high idle. I tightened it more than I thought necessary and solved my issue.

That was my concern as well. I need to check the tension of the belt, but viewing the side of the radiator, it looks to be full of mud....

I ordered some radiator spray nozzle things. They will be here Friday, hopefully I can get this worked through the next few days and just watch the temps. Ill report back if anything else shows up.

Judging by the looks of the parts manual it would appear to be almost impossible to clean the cooling pack with the fan shroud still installed. The one fortunate thing is that the radiator & oil cooler are mounted side by side instead of being stacked one behind the other as they are on many other machines.

Yeah, thankfully they aren't stacked tight and deep like some are. Its just getting that shroud off, or at least trying to get between the shroud and radiators.

I bought one of those radiator cleaner bars, its pretty thin and goes on a pressure washer, so I am going to try and see if that'll fit in there. I have a hot pressure washer I can adjust the pressure on, so I don't kill the fins themselves.

Worst case scenario, I am pulling the radiators out, and if I am doing that, its getting a water pump, thermostat, and A/C compressor... Ha!

Well. I got the fuel tank low. And I can’t get the tank to budge. So I’ll have to figure out how to loosen all the bolts and move it. But I don’t think I’ll be able to do that without some serious parts removal.

It acts up when it’s gets very close to operating temperature and more so when it’s over 195°.

Wondering if the hydraulic rad is not cooling the hydraulic oil properly and the pump isn’t happy about it.

I received my radiator cleaners so I need to get it somewhere I can work on it now.
