Cold-Blooded Diesels
Re:Cold-Blooded Diesels
I have the Lund polished stainless steel weather fronts (Ordered from NAPA). They have little slits in them so a little air gets through. I have a 180[sup]o[/sup] thermostat and would like for the water temp to run around 200[sup]o[/sup], especially in the winter. The air down at the bottom is plenty for the trans. cooler, even when pulling the TT.
Tony, the 70[sup]o[/sup] looks good when theres 2 foot of snow and ice everywhere.

I just take off the fan for the winter. This will be my 6th winter fanless. I only put it back on this summer because I wanted my A/C. The only time you will get hot is if you are sitting in a traffic jam. Even then it takes about 30 mins to get to 200° Once the truck is moving it comes right down. Turning you heater on high will drop the coolant temps about 20°-30°. Hands down one of the best mods I have done.

Re:Cold-Blooded Diesels
I have to cover some too, so the heater will be worth using.
I think keeping the operating temp up in the winter will help your longevity.

You folks should have bought heated seats!!!!!
I know my diesels when it's under 15F or so take at least 10-15 minutes to get good heat out of the vents but the seats only take about 2 min.. Also if you sprung the incredible $10 the engine block heater now costs, you will have heat sooner 
Hoss don't rub it in
Some of us are only temporarily down in the warm weather. I have to move back to wonderful, tropical......Cleveland in May...gotta love when work takes you to exotic lush climates

Man I dunno must be a heck of a raise. I hate the cold. Naw hate isn't a strong enuff word... :P

Re:Cold-Blooded Diesels
I don't know I ALWAYS plug my truck in .....when it's real cold the 3cylinder idle cuts in, I let it run like that for 10 minutes and the heat starts coming on about 1 mile down the road
never needed a winter front ...........that 3cyl idle warms it up pretty fast
I will say I do 95% highway driving ...........I almost never drive around town as you can walk anywhere in it in 5 minutes (it's got like 800 people) ............. I have noticed when I do drive around town it stays pretty cold so a winter front would probably help there
I also have those lund snap in bug screens, they probably block some air too

Re:Cold-Blooded Diesels
here's the tsb
Once enabled, idle speed will slowly ramp up from 800 rpm to 1200 rpm when all of the following conditions are met:
1. Intake Manifold Temperature less than 0°C (32°F) and,
2. Coolant Temp is less than 60°C (140°F) and,
3. The Transmission is in Neutral or Park and,
4. The Service Brake pedal is not depressed and,
5. Throttle = 0% and,
6. Vehicle Speed = 0 mph
Additionally, if Intake Manifold Temperature (IMT) is less than -9°C (15°F), and all of the parameters above are met, three of the cylinders will be shut off upon reaching 1200 rpm, creating a slight change in engine sound which is normal. This allows the engine to create increased heat in the cooling system, allowing more rapid engine warm up and cab heating.
it probably won't get cold enough in florida to work anyways

Re:Cold-Blooded Diesels
Hmmm, engine is more technical than I had imagined.
Anyway, I can't see how reducing the number of combustion areas would help increase the rate at which the coolent increases temperature!? ???

Re:Cold-Blooded Diesels
I don't know exactly how it works ...but it works as they say
my theory is that the 3 cyliders left have to do more work since they have 3 usless cylinders to pump (they still compress ect just no fuel is added to them) & the extra work causes them to burn enough fuel to make extra heat ???
just my guess

Re:Cold-Blooded Diesels
I think I have it. It takes more effort for three pistons to move a truck than six. The greater exhaust temperature is what heats the engine faster.
Of course, now we have uneven heating of the block, et al.

Re:Cold-Blooded Diesels
fuel act like a coolant. my guess is that not the same 3 cylinders fire all the time it varies them every couple of revolutions because the fuel also lubricates. the electronic fuel injection allows for different cylinders to be sprayed the ones that dont fire are still compressing air which is still hot enough to light the fuel off but is not there so the heat is absorbed by the engine.
