Listening to ya'll I'm starting to wonder the same thing. ???

I gotta go pick up some oil &amp; fuel filters this weekend, looks like a new T-stat is gonna be on the list too.

Up in Northern AB and NWT when the temps really drop, you will see a lot of diesels wrap up completly to stay warm. This is on both big rigs and pick-ups and means a belly tarp and winter front on and buttoned up tight. I personally think this is to keep them warm when not working &quot;real&quot; hard, like idleing at night or on work sites, and probably helps on speed up the warm up when started. But if the T-stat is working right the temp should stay normal no matter what the outside temps are once the engines is warm and working. Speaking from my personal experience with this truck (first Dodge Cummins) and the temps here in the morning dropping to -10 Celsius the truck just takes a little longer to warm up in the morning but once the temp is up to 90 (Candian Trucks are in Celsius) it stays there all the way to work. I think I'll put a winter front on in the next few weeks just to speed up the warmup.

A blast from the past. <br><br>Update.......just installed a new 180* thermostat, went for a test drive..........EXACT same results.......outside temps ~55*f, guage rides about 1/4 of the way between the first &quot;warm&quot; line, and the 190* mark.<br>Now I know that my Temp guage reads about 15* on the cool side.<br>BTW only running with the two upper guards right now.

I guess I should put my guards on today, at least 2 of them.

Cold weather. It's 85 degrees and sunny here in Houston, Texas right now. Cold weather. Ha. Anything below 60* is cold to us. Maybe I should get some winter fronts for those occasional 50* nights.

See now here I go again. I've seen them grillecovers by lund and thought &quot;thems the funkyest replacement grilles yet&quot;<br>Function and style is so hard to tell apart some times!!! .<br>at 0 to - 10 I have never had a problem with my truck reaching normal op. temps. Of course my wife goes out a 3/4 of a hour every morning before I leave and fires up my other love for me!! I don't plug it in. If my wife ever gets fed up with my other....and she leaves......I might have to plug it in.<br>Before I leave work I let it Idle 15 minutes. I do this whether it is -10 or + 110. Saved that $$$ and spent it on momma to butter her up for the next mods. Of course those grill covers are easier to find and probabley cheaper thanthe ol' lady!!!!

Amish hauler, have you seen this thread about idleing the Cummins?<br><br>https://www.dieseltruckresource.com/...;threadid=6208

Amish hauler

Just read the thread. (hey that rhymed!!) I would never want to second guess the engineers!! I have read about this in the past and even asked a fella that worked for cummins.(don't know his title....could have been janitor for all I know...) and he pointed out that there was a intake air heater of mega watt power that in conjunction with the heat of idling before adding a load to the engine helped bring it up closer to operating temp. When that heater kicks in believe me it adds a load to speed up heating even more. As far as excessive idling (hours-overnight) I have yet to see any reason for this on the cool down side beyond cooling down the egt. after heavy loads. to keep hot oil from boiling in the turbo. I wonder if the shut down idling may be more what they were referring to versus warm up idling.<br>Although I admit I let it run versus shutting it down when i come for brief stops such as 7-11 or Mik &quot;D&quot;s. Always heard time spent building oil pressure was where wear came from. My CTD takes for ever to build pressure if you believe the guage. <br>Maybe the author and other drivers intake heaters may not be up to par? Mine dims the lights when it kicks in. And changes the sound of the engine. Even after running my one waytrip to work of 150 miles that intake heater will kick in after a few minutes of idling in cold weather.

Amish, that is called the Grid Heaters. They are what is heating up while your wait to start light is lit. They kick off at speeds above 20 mph.<br> Are you in PA. near Lancaster?
