My normal temperature usually runs about 200 or so load dependent. That's at about 12-1400 rpm 2nd gear hi range putting down the road.
As of late, I think my thermostat may be sticking as it went up to 220 and then it went back down to 180 and crept back up to about 200. Coolant level normal and is a 50/50 mix. Radiator flutes are clear and clean.
I've been acquiring parts to replace the radiator as it has a pinhole I can't get to for repair on one of the flutes. While I'm at it, the water pump and thermostat will also be replaced. They are 50 years old so why not? I'll flush it all out good too.
I want to do it all real good while I'm into it.
What should the thermostat open at?
I want to test it before install in a pan of water. It's not marked on the thermostat.
What should the temp normally run at a moderate load?
Say running a 6 ft rotary cutter. I want to say it was about 210 maybe a little less last summer at 16-1800 rpm.
Its getting time to do this before summer so I need to get off my butt and get the rest of my stuff before summer cutting season.
Thank you guys once again.
