The removal and replacement of one in a diesel pusher is a difficult process....I've done many over the years. On a Toter it's usually not so bad.....compartment mounted somewhere on the side...usually

It would not be hard to get to $2 grand or more...I generally do a complete service and change some parts known to fail while I'm in there.

The flex pipe coming off the engine breaks on those.

The flex pipe alone is well over $200...

External pipes are usually custom made or made from Onan pipes readily available.....

Thanks, Rich! I completely understand that you can't tell much without seeing it.

Mine is in a side compartment but it doesn't slide out. When you mention the flex pipe breaking, I almost assume without looking that I have that issue. All I know is that I have an exhaust leak of some type. I smell a lot of fumes even with my stack hooked up.

I very rarely run the thing unless I need A/C. It would be a lot cheaper on cash outlay and in fuel for me to get another 2000 watt inverter generator and run it as a companion with the one I have. That's what I run my stuff on during a normal race day.

The Onan has something like 5600 hours on it, so may not be worth sinking a bunch into but it works when I need it.

Anyway, thanks again!

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....
