cold weather idle

The Series 60 is pre-set at 1,000 RPM by turning cruise control on, then hitting the "resume" button. How ever, it seems it was lowered to 900 RPM to save on fuel. I can tell a Series 60 idling at 900 vs 1000 RPM. 1,000 RPM sound's the best to me. Even at 600 RPM, my Series 60 maintains about 40 PSI in oil pressure. I'm running Mobil Delvac 15W40 and Fleetgaurd filters. After changing the oil and filter, my oil pressure has been up a few pounds. I always idle at 1,000 RPM, before I shut down I will run low idle. Do what you want.

 

your ECM is programmed like that to help it warm up.

As a cold engine, it actually needs the speed to allow it to run. Otherwise it isn't able to burn the fuel efficiently.

Just like the fast idle on your car.

 

my 2000 60 series jumps to bout 900 on cold start use to worry bout it but 960,000 miles later no problems.i dont let it idle any length of time always set it bout 900-1000.or get motel cheaper

 

DDEC IV on a 2000 Freightliner, cold start idle about 900, also changes the cam timing to run better until operating temperature. Hate to idle it for long periods, but maintaining engine temp and burning all the fuel in the combustion chambers are very important.

As far as winter fronts... When modern electronic engines are equipped with fan clutches, and the thermostats are working properly, a winter front is ineffective. When the truck is standing still, the thermostats circulate almost no coolant through the radiator, and of course the fan is not turning at all. At road speed, the same, the thermostats will determine with far greater accuracy the temperature needs of the engine than a fixed winter front. Now if you wanted to go back to the old variable shutters on trucks of yore, then have at it.

 

Depending on where u are running a winter front is very effective and if you run a newer truck with dpf an urea you will need a winter front when it nears the freezing mark to keep the engine hot enough to operate properly. Just cause u have properly functioning thermostats means nothing if your running in cold temperatures that air is cooling off the coolant in your rad and your oil pan especially in a Cat u definitely Need to keep your water temp over 180 and your oil temp up. It's very hard on an engine idling down the road and being cold.

 

hotel cost what 40 to 80 bucks a night. cost me about 5 bucks to idle all night. heck i just spent 2 days in KY nonstop idling. i had filled up when i got there so i was ready to roll when my trailer was ready to be picked up. decided to top it off when i left and only took 35 bucks to fill it up.

As for the idle question. normal on a detroit in cold weather. i always kick my up regardless of outside temp. it burns less fuel that way keeps oil flow to the turbo and other parts remember alot of your top end counts on oil spray to get everything lubed.

 

what kind of super efficient engine are you idling all night on just over a gallon of fuel. heck even the brand new SCR engine still burn at least 1/2 gallon a hour. even webasto heaters use at least a full gallon to heat the truck for 10 hours

 

motel only way to go if you need to run engine,if you cant afford one your already in trouble
