1st Time 2nd Gen 24V Cummins Owners , Winter

[DieselMinded]

Just post up some tips and tricks and FAQ about the 24v 2nd gen Cummins for you new owners ,

Headlights Diming Is normal that's your intake heaters cycling , Your intake heaters is a block of fins that are heated and when the air passes threw them its heated so hot air is going into your engine ,

You dont have any Glow Plugs Your Initial Firing is Cold Oil , Cold Block and Cold Air , so it may start ruff , And if its really cold it will shut a few cylinders off to stay running , You have no "FIRE" your engine relies 100% on compression Ignition of Fuel and Air inside the cylinders,

Give your truck a break and PLUG IT IN !!! , its not a constant draw of electric it heats up then cools down then repeats Make a Big Difference .

DO NOT USE your windshield wipers to remove snow/ice from your windshield , The motor is not very tuff and it will break.

Run a Fuel Additive if its really cold Dont run an Emulsifier Style Fuel Additive , You Want a Demulsifier Additive during the winter It will say on the label which is which

Emulsifiers Join H20 Molecules in your fuel system in hopes of capturing the large chunks of water in the fuel separator , This can cause Frozen Lines as the H20 is grouped

Demulsifiers disperse H20 molecules in your fuel system with hopes of passing threw your fuel system and injectors unnoticed , having the H20 dispersed will be less likly to freeze

yep the this morning my wait to start light stayed on for about 7-10 seconds i almost started it just from habit...so boys and girls get ready it wont be to long now

If you can let it run for a little bit as soon as you fire it up...dont just start it and take off it can be hard on everything your oil touches. So let the oil get a little warm so it can do its job!

ESPAR or WEBASTO hydronic engine heater.


I hate winter.

Uhh, well, no. Sorry but this is simply not correct. The modern ISB and ISBE trucks warm up much faster when they are being used inside the load range. Idling does nothing but wash your cylinders, waste fuel and piss people off.

What you want to do is get it running, scrap the windows and slowly get it rolling. Driving way under the speed limit for a few 100 yards or even miles depending on where and how cold will get you the results you want.

If your truck has the latest flash it will engage the high idle if it is really cold and if that's the case this is ok to let it sit for a bit as the motor is in the load range and will generate heat. This will not wash cylinders but will still waste fuel.

Cheers.

And i thought I knew a thing or two

Hey, no harm, no foul. Just wanting to point out that in winter most people thing they need to let it sit and warm up. Doing this will just cause problems. Sometimes VERY expensive problems - which compound if you have big injectors like I do as I already have excessive amounts of blow by as a result of those sticks...

I wasn't picking on you, please don't see it like that.

It's been my experiance that letting the truck just sit there and idle doesn't allow it to warm up anyway. I've let mine sit and run at work when it was 15 degrees out. Idled for nearly half an hour (not a good idea for reasons above) and the coolant never got above 120 degrees. Now If I activate my Jake Brake when I start up, it will be up to temp (170+) in just 10-15 minutes! Gotta love exhaust brakes.

[MOUNTAIN MAN]

I agree, I warm my truck up w/ the the exhaust brake on, for five min. tops. Just a slight load on the engine, and exhaust temps @ 400+

[Wyatt Earp]

Exactly. A lotad by moving, by high idle or by restriction like a brake will get the results you want.

[Phily 911]

Adjusting your seats and creat that high idle. Works wonders.

[kazairl]

From what I understand the high idle feature has to be turned on by the dealer. As well as the 3 cylinder idle. Or a homemade Potentiometer spliced into the wiring, or a stick against the pedal. Or some other after market means. Like a Smarty or Adrenaline.

I agree with the above too. I idle my truck for a min or 2 then drive it easy till I hit the Highway (1 mile rough dirt road) then take it easy as I accelerate to the speed limit. After that I set the cruise and forget it. It usually takes about 5-7 miles before the needle hits 170. Longer if its really cold.
