CK20 Running Too Hot

[Highbeam]

I understand bluechip and to drive that point home please take a peak at what can happen to plug up the outside of the fins in a radiator. This happens to be the radiator from my old International dozer but as you can imagine, the overheating problems were no mystery after I found this. Unfortunately the radiator on a dozer is not easy to get to and this one could not be cleaned in place.

After cleaning this out the fan would roar as it blew enough wind through the coolers to fill a blimp.

The inside of a radiator can also plug up with junk but on these mostly newer Kiotis we should first expect the outside.

PS, just in case someone is confused by the fact that the junk is accumulated on the engine side of the radiator, the fan on a dozer blows out the front of the grille. I wasted a good portion of a beer once spitting onto this mat of dry organics when the fan blew a nice ember onto it from a fire. Then the fan blows on the ember and pretty soon there is a real potential for a major fire.

The owners manual for my CK20HST says to flush and change coolant every two years.

You might also have your radiator cap checked, a low pressure will lower the boiling point of your coolant. Also your mixture should not be more than 50 percent antifreeze.

My LK3054 was running hot a couple of times and I discovered the cause to be the overflow tank cap. It popped open and I lost most of the fluid in the tank. Just topping it off cooled it right down.

Joe - that's some picture of your radiator! I was mowing a few weeks back - very dry day and noticed the machine was running a bit warmer than usual. I decided to do a quick visual on the radiator fins. Don't know if most other machines have one, but mine has a fine mesh screen in front of the radiator. The part manual refers to it as "Radiator Net'. Clogged pretty good, but it cleaned up nice & quick using an old paint scraper. Ran nice and cool after that.

ROTFLMAO

...and the engine cowling is a light piece of work to lift off too, A 3-beer job!
