Warming Up My 6.7 In Cold Weather

[AH64ID]

I towed some pretty good grades out west last summer with my 12,000 lbs. 5th wheel... with my Aisin...never got above 180 even with the engine fan roaring to keep engine cool...going up some long, hot and high grades. No temp issues with the Aisin.

Wrong thread?

seriously?????

yup. do it every day with mine. works great. warm engine and trans in under 5 min. The trans puts nice load on the engine, and it heats the trans at the same time.

When it’s below -10°F I will put my xcase in N and my trans in 5th and let it fast idle for 3-5 minutes. It really improves shifting and warmup. Above -10° I don’t feel the need

on my 08, i've not been able to get it to shift to N, i get high or low, no N. good idea though. thank you for the thought.

Electronic or standard shift xcase?

 

[Killer223]

electric. it has a pin hole you are supposed to push. I've fallowed youtube videos, still doesn't work..

Gotcha. I’ve never tried an electric one.

I thought in cold weather the new trucks like my 2015 automagically idle on the exhaust brake. Mine seems to anyway. The Banks brake on my 2001.5 also did this automagically.

This winter has been my first experience with temps below zero since new in 1999. Been plugging in the block heater when below 40 degrees and warming up the engine for a few minutes to get some temp before driving easily until normal engine temp rises. Good thinking using the xcase in N and running the trans in 5th.....going to give it a try this weekend when the temps fall to zero again! Thanks!

Mine does not. It simply ramps up after two minutes, I have to press the exhaust brake if I want it activated.

Well my exhaust brake comes on during cold mornings without pushing to button to turn it on, I am fairly sure of that. Weather has cooled this week so I can verify that. It is much more subtle on the 2015 vs the banks brake on the 2001.5. It will even comes on at a stoplight idling in gear when the engine is still cold.

I'll be spending time in Dad's '17 later this month in the COLD so I'll see what it does.

Did you have to engage the brake switch on the 01.5 with the switch for it to work when cold?

NO, the Banks controller has to be turned on, and if water temps were lower than 140 degrees it idled on the exhaust brake. Not only help it warm up but also keep it freed up and working good by cycling it at each start up.

Same here.

In 2013's, the manual suggests turning on the brake for faster warming. Mine Doesn't do it automatically.

But if the 2015's do (automatically), that is interesting.

How cold of temps are you referring to?

This is my first winter with this truck but we've seen lows down to -17 so far and the EB has not turned on.

 

[Learjet]

Sorry my last post was wrong thread...not sure how that happen

 

[SnoKing]

Well I just played with the exhaust brake, and as others said it is dependent on the brake being in full or auto. It does come on at stop lights while in gear with my foot on the brake. Sorry about the confusion earlier. Snoking

Masterdrago,

I too have a 2017 but it is a 2500. First, we don't have block heater cords for our trucks in Texas unless you install the cord yourself, ordered it with one from the factory, or the truck was an import from the northern climates. Texas trucks typically don't have them standard. I grew up in Alaska most of my life and know first hand how invaluable they are at -50 in Fairbanks but in Texas they're overkill so I wouldn't waste my money unless traveling north in the future. As for the weather we recently had when we saw temps in the 20's, I simply remote started mine as I was getting dressed in the morning and within a couple minutes I could hear the engine RPMs increase automatically. By the time I got in the truck, my coolant temp was showing to be about 90 degrees. On the morning when we had 22 degrees a couple weeks ago, I hit the exhaust brake manually but quickly turned it off because at 4:40 in the morning my neighbor might not take it too kindly. And in my experience up north, using the exhaust brake to reduce warm up duration is just fine as long as you don't idle the heck out of it...thus the reason you utilize the e-brake to warm the engine up but reduce the idling time to do so.

How low does your coolant temp gauge register? Mine only goes down to 100 degrees.
