Onan Generator part needed

Those machines can and do go way more hours than that with good maintenance.

The exhaust flex is broken, I almost guarantee it....

I did one last winter that sooted up the inside of the unit really bad from the leak.

It's a flanged u-bend type flex and the vibration breaks the flex connection to the pipe flange.....no way to repair it other than replacing it....

Water pump belt needs changing and that's a must along with routine full service and inspection.

Another good thing to do is pull the t-stat and replace it along with the temp. sender. check the inside of that area for corrosion....it can get real bad. If it is the radiator may also be in bad shape inside.

They used Dex Cool type antifreeze in some and it caused issues....
