...is this normal with ambient temperature at 44F?

Temp gauge just within the normal bar and the upper raditor hose is cold - Thermostat housing warm.

5.9 quad automatic 3:73 and just 600 miles.

 

That sounds the same as mine, especially slow to warm up in city driving. I bought the winter front from Dodge - that helps alot, especially when it gets to the 30s and below.

 

Thats normal, these things take forever to warm up in the cold if your just putzing around

 

Well - if you think about it; you do have to bring 1100 lbs of cast iron, forged steel, and a few other alloy's that make up a CTD up to around 180 ~ 200 degree's F. So it is going to take some time to do so. These engine's loved to be worked hard, otherwise they run cool.

I have to drive about 12 miles @ 70 mph before mine is good and warm.

 

Welcome to the wonderful world of Cummins!

 

The winter cover helps.

 

It was @ 50* here the other morning, and I left my house, and drove almost 30 minutes through town before it started coming up to operating temp. Put it this way. If you just start your truck in teh mornign, and let it idle....it may NEVER come up to temp. I left my truck running about a hour one morning, and I came out, and it was still pegged on teh cold. So, yes, it is normal.

 

Yeah, even in 90* temps it takes a good 15 minutes to warm up in the city.

Try driving down a long canyon road in winter temps. Your engine can be 210* at the top and it will cool down to 140 or less on the way down. Cold enough that the heater is blowing ice cold air.

 

when I kick my PTO high idle on, my truck warms up FAST.

 

yu can buy the winter front from dodge parts link below

it fits behind the grill like a glove will warm up the truck in five miles of driving

 

Every person i know with a cummins has the same issue with warming up. It takes me about 12 miles @ 70 to get my truck warmed up. )

 

mine warms up in about 1 mile, at highway speeds, when below freezing. Thanks Espar

 

It's just normal.......as said before a lot of everything to warm up, iron, oil, fluid..........You can drive in a lower gear to keep up rpm's to help a little....but only after initial warm up

 

It's a Cummins, ie long warm up time. Buy the winter front and plug it in at night. I have heat within 50 feet of my house. If you have an exhaust brake, use it. You will be amazed at how good they warm up the engine.

 

use the high idle, works good for me
