Warm-up times? (ITS HERE!)

[Archive]

Yeehaw, I got the magic call and picked her up yesterday evening! #ad
Actually, I happened to see my truck being driven by a tech before getting the call from the dealer - so I about jumped through the windshield of my buddy's car screaming "HEY, THAT'S MY TRUCK!!" (And it was!) #ad


So my question is: how long do you have to warm up for? Can you drive away with the needle still showing 140? It was a chilly 58 degrees this morning (Which required the heated seat option to be turned on!)... and I let it warm up for a few minutes, but the needle didn't move. It was also 5:30 am and the neighbors finally received their formal introduction to my new toy. #ad

Scooby,

It WON'T warm up idling! In fact letting it idle when it's cold is not a good idea. The best thing is to start going as soon as you get oil pressure and take it easy until the gage shows some temp. These are tough engines with a REAL cooling system and a lot of iron to radiate heat. If you have TDR issue 22 look on pages 64-65 for a discussion on idling. Congrats on the new truck!!! ENJOY! #ad

Thanks Joe... . that's pretty much what I did... since I'm also aware that you shouldn't idle a new Cummins for more than a few minutes.

But I guess my question remains. I hear about exhaust brakes being beneficial in that they warm up the engine faster. So I should interpret this as meaning they warm up the engine faster while you are taking it easy (and driving) rather than sitting in the driveway, eh?

She's a beauty! I had to come in to work way early to get the pole-position parking spot #ad

If 58 is chilly I must live in a freezer since our high today will be about that #ad
Just start her up and wait for the oil pressure to come up and the manifold heater to quit working (if it even turns on) and drive moderately until fully warm.

Scooby,

The exhaust brake only works with the throttle at idle so it won't help to warm it up while you are driving. BV is right, just leave as soon as it's over the start up drill. Remember, you have to work at it to hurt one of these beasts. I had about 1K miles on mine when I took a 10K mile vacation trip hauling a big camper. That worked it enuff to break it in right (and let me show it to my cousins and do some bragging!!). It now has over 140K miles on it now and still doesn't use any oil.

Congrats on your new truck! I idle long enough to let the oil pressure settle and then keep it at 2000 rpms or less until the temp needle starts move. I don't run it higher than 2500rpm unless it's fully warm - 190 You can hear the piston slap when it's cold, I use that as my guide mostly...

I start the engine, make-sure all lights go off and oil pressure is up, and then drive off carefully (keeping RPM below 1600) until water temp. is up to 190.

Douglas,

190? I seldom see that temp unloaded. In fact, last winter I drove all the way to work (20 miles) a couple of times and the stat never opened. BRRRRR!!! The stat normally opens just below 190 (~185) and that's it. Dane has got it right. 2000 with no load is loafing for these engines. I'm normally running about 1800 or so since that's about 70MPH with the auto OD and 3. 54 gears. 140K+ miles and no oil use at all.
