    Default Bobcat Code 08-21 Hi Temp.

    I have a code 08-21 Hi temp.on a Bobcat 773 and the gauge shows Hi Temp. it comes up from the time you start it up but coolant is running from 160 to 190 and oil Filter temp. is about he same when it is under load running a Brush Hog. All looks normal any thoughts?

    Thanks for moving it to where it should have been. I think that I have found the trouble I cleaned the battery posts and the main ground connections. and all seems to be normal.

    glad you found it. A bad ground will wreak havoc on the computer. You might already try this trick but if you are mowing, put a piece of cut to fit AC filter between top of radiator and protective cover. It will help catch debris and keep you running longer before radiator plugs and you get the same error code. Metal window screen works well too. Mowing with brush mower out front will eventually lead to clogged radiators on a Bobcat.
