Over heated

**Johnf** · 10-14-2017, 04:18 PM

I was brushhogging some pretty thick stuff and my temperature light came on. Probably wasn't on for more than a minute and I shut it down and walked away immediately. How long should I wait to crank it back up again.

Biggest concern is to address why it is overheating which is probably due to the screen in front of the radiator is full of thatch and seed hulls and is due for a cleaning. The other thing is the cleaning the radiator fins itself which might have some debris and dust build up.

Once you do that usually one of the fastest ways to cool the engine is by actually running it and letting the fan draw air across the radiator.

Ok. I was brushhogging thick spindly brush and tall grass with millions of dandelion type seeds flying everywhere.

You don't want to just turn off a Turbo engine like that. Letting it idle cools it down and cleaning off the air screen on the front of tractor and then check your radiator screen. Damn seeds get in everything. I had my light come on after driving my tractor from my Dad's house back to mine. 4 miles on a hot day. Just pulled over in the shade and let it idle and when it cooled back down continued home.

Do I have a turbo? My 4010 is an MCUT. Cleaning out the screen did the trick. Cooled down in about a minute.

Good deal. Your post didn't say what tractor you had so I assumed it was a 1025. Anyway, glad it worked out for you.

No turbo on the 4010.

Your absolutely right! It's just habit from running heavy equipment for a lot of years and we always idle them down when they over heated or shutting down at the end of the day, so as not to damage the turbo and the engine. Sorry old habit. What I should have said is that you are not supposed to just turn off a diesel engine when it's that hot. It's in the manual, for the 1025, that you are supposed to idle the engine for 2 min to let it cool down after hard work load to avoid damage. I'm going to assume that the manual for both say the same thing about shutting down? Either way, with or without a turbo, should never shut it down like that is the point I was making. Avoiding costly repairs is every owners goal, right?
