Good evening!

the good news is -- we bought the 1999 Diplomat and so far, we love it. The Big Trip starts Wednesday, off to AKC Agility Nationals in Tulsa. BUT -- the engine temp is running close to 220 and we seem to be getting LOTS of coolant into that thing by the radiator in the back. What's going on? Our fault? Their fault? Not to worry?

thanks -- Pam

Call Monaco and run it by them. Before you call, know which engine you have. And be aware that guages are not always accurate. That thing by the radiator is the coolant overflow reservoir. There is more coolant in it when the engine is hot and less in the morning when the engine is cold. You have come to the right place for answers, but you need to do your homework. Get a yellow highlighter and read your owner manual from front to back, twice. Have a good trip and give my best regards to the dogs.

Hi Pam,
Congratulations on your "new to you" coach. I know you will enjoy it. I suspect you have a Cummins ISC 8.3L engine. Good engine.

At 220ยบ F you are running a little higher than I would expect. Could be the sender or a poor ground connection. But may be a lot simpler.

You have a rear radiator and a lot of "stuff - dirt, oil, etc.) gets pumped thru it. Just the nature of the beast. Unless you know different, figure that the prior owner never cleaned the radiator. Not hard to do.

Put some "Dawn" liquid dish soap in a spray bottle, open the rear doors covering your radiator and spray the heck out of the entire radiator fins. Let it stand for about 15 minutes and then flush the entire surface with lots of water. DO NOT use a pressure washer. You could damage the fins. The average hose sprayer can generate enough pressure to force any accumulated crud out of the fins after the "Dawn" has loosened it up. Don't be afraid to repeat the operation a second time.

If you try the cleaning, please let us know if it lowers your operating temp.


Green lights and soft breezes,

Pam, sounds like the radiator needs cleaning. Yep, needs to be done at least once a year if you put many mile on it. There is a tube coming down on the side of the engine and most likely hanging down just below it. This is commonly known as a breather, better known as the slobber tube. It expels small droplet of oil which wind from driving and pull from the fan push it into your radiator core. Once there it starts to collect dust and dirt. If not removed it will clog the radiator and overheat the engine.
Nope, it isn't a big problem to clean the radiator, just a bit messy. If your bed lifts up to provide access to the engine, all the better and easier.

Here is what you need to do. First find the slobber tube and put an extension on it to well below the bumper. The tube is about the size of a garden hose and you can get an extension at Lowe's or Home Depot by the foot. Next cleat the radiator as follow:

Radiator Cleaning Process

1. Put any good grease cutting detergent in a garden sprayer (pump up pressure tank type) in the proper dilution if any (not gunk or any of that type cleaner).
2. Then spray the radiator from inside the coach trying to get as much coverage as possible.
3. Close the hatch. Start the engine and then run it up to about 1800 rpm for a minute or so and shut down.
4. Go take a break.
5. Now spray the radiator from the inside with water, rinsing as well as possible.
6. Close the hatch and start the engine again and run it up to 1800 rpm and then shut down.
7. Check the radiator and see if it looks clean. If not clean enough repeat the entire procedure. If it looks clean then go thru the rinse cycle again.

It is the only good way to clean the rear radiators. Make sure that the rinse job is good. Any cleaner, even the Gunk type stuff (which doesn't clean all that well) is somewhat corrosive to the aluminum radiators so thorough rinsing is the key.
