Chipper gets hot

Try to turn your fan by hand. An old glazed belt will slip. It should spin the crankshaft on an engine like that.

I had it explained to me that a cooler thermostat can lead to problems. An engine that does not reach proper temp may not evaporate any water in the oil and may have deposits build in the combustion chambers. Not my personal experience though. I always run 180 or hotter.

Cold engines die young.

No shroud.

I have had radiators that looked clean on the outside have a lot of dirt in the middle.

I can't count the number of times in the past that we had to blow out the radiator to clear over heating problems.

Even on site. The sycamore fibers would plug a radiator in 30 minutes of chipping. Tan oak, too.

the 160 was the std for that motor until the 70's emission requirements came along.

I burned out the original aluminum rad on my bandit 250xp with a JD 140hp diesel in like 1750hrs. I had a replacement built locally out of copper and brass for less than ordering a new one from down south, and I have it built with larger spacing between the fins. Now my chipper runs dead on 180, never gets hot. Blow it out now and then as a preventative/inspection thing and it's super easy to blow out because the fins are so widely space, rarely much in it. I'd have a rad shop look at your rad if you're wondering about it.

I would think the excessive paint/filth on the motor would be a big heatsink and could be a big cause of your problem on a hot day. I'd get that cleaned/stripped.

If you have scale build up in the engine it can run hot. Scale the thickness of a couple of sheets of paper is the equivalent of three inches of cast iron as far as heat transfer is concerned.

I did not know that. I thought that 180 has been standard for ever. Of course, "for ever" personally started for me in 1983!

No scale. Paint is on the housing over the engine.

When I pull it out of the pole barn from painting, I'll back flush the radiator fins with water. Air didn't do much.

IMHO a fan shroud should be in there. Paint is looking good though!

I agree about the shroud, and will have to look into it.
