Ether bottle: When should it be used?

In his response to another topic here John Sichenze said:

"The M 11 has no glow plugs. In fact my unit came with a bottle of ether plumbed in."

We have one, too.  Our salesmen told us to never use it without first talking to Derek Diverdi. When would I use it?

Note to John:  Thank you for the good topic idea.

Inasmuch as we do our very best to avoid really cold weather, I doubt if we will ever need it.

Cold weather is one reason or when your engine position sensor is on the fritz and the engine will not start and there is a nor easter blowing in and the campground will be under water.

I have started up engines in very very cold weather. I do not make a habit of using it but if it is 20 below and you are in Iowa you will need it even if you have aquahot and preheat going.....

Just a word of caution here:

I am not familiar with the M11, but most newer engines (both Caterpillar and Cummins) have intake manifold heaters that aid in starting.  Hit that red hot electric grid with ether and you have an EXPLOSION.  So, before considering ether, consult your engine manufacturer to make sure your engine does not have an intake manifold heater.

Brett, you are right but my ISM does mot have one and it is an 2001 but my 99 ISC had one. Go figure.

Our 1997 U295 with C8.3 engine sports a big sticker that warns against using ether because of the flame heater in the intake manifold.

J. D.,
 
What's a flame heater?  I have the same Cummins C8.3 engine.  I assume it is fueled by diesel?  How does it ignite the fuel, with an electric charge?

I don't what is a "flame heater." I just repeated the warning on a label on a cross member behind the engine. I have found no controls for engine preheat other than the electric block heater.

Likely an intake manifold heater, hence the warning-- red hot electrical wire plus ether= EXPLOSION.

Revised. . .
Our Cummins 8.3C-RV diesel engine has a pre-heat cycle to help heat the cylinder to a point that the diesel fuel burns when injected into a cranking engine. While the 'wait to start' dash light is lit, the 12 volt electric grid heater in our intake manifold is heating the air before engine is started. Once the engine is running, on-going combustion keeps the cylinder hot enough to burn fuel.
It is probable that the pre-heat option was ordered with the engine from Foretravel.  Some other diesels may also have some sort of pre-heat.  I was incorrect to think that all diesel engines need a pre-heater.
 
After turning on the ignition key, we wait for the light to go off.  The colder it is, the takes longer for the light to go out.  When it is cold outside, we cycle the ignition key, by turning off the key when the light goes out and then turning the key back on for a another 'wait to start' heater cycle.  Repeat as necessary.

George,

The M-11 doesn't have any intake manifold heaters, hence the installation of the supplemental ether system.  Given that, everyone's cautions about its use still apply.

Hi George,
  Our 1997, M 11 powered, has the ether bottle, factory installed. When I purchased our coach, the seller said to never use it. Our first trip to the factory yielded the same advise from James T. Just never use it. I have never thought much about it until reading this.

My '91 GV with a Cat 3208 also has it.  The Cat manual says to only use ether if it is below 30 degrees outside.  If is is going to be that cold I turn on the block heater as it warms the engine oil and makes it much easier to start.  One thing that I notice is that without a manifold preheat the engine puts out white smoke until everything gets warm when it is cold outside.

Not on any of the over the road equipment that I ever drove.  That included Cummins 250, 290, formula 290, 330/370,  335, 350 and the 400.  And on the Detroit 238, 318,  350 along with the 6V92 and the silver 6V92.  All any of those had was the block heater and a couple had the ether canister.  Never had any steady Cat experience, so I don't know about them, but trust Brett Wolf on that topic.  And all my Cummins B5.9 has is the block heater and the ether canister.  But my VW Jetta TDI does have glow plugs.

It really does depend on how cold. I have been in areas where it is so cold you never shut your unit or car off or where the night temps are below zero. Sure, we would all like to be retired and go south but sometimes I go north inthe motorhome or even west and get some might cold weather. the coach is fine in it and we are all toasty warm but it is a bear to start when it is that cold.

Why not install a 1500 W Kim Hot Start block heater?

Turn it on 20- 30 min. prior to starting, everything will warm up and cold weather starting will be easy.

Ted,
 
I think that all diesel engined Foretravels already have block heaters.  The only thing is that you have to be hooked to shore power or run the generator to make use of them.

I think you are right John.
Looking at the specs going back to at least 1985 they all had Block heaters.
