heat in the ho diesel

[powerwagon]

how long should it take to get heat out of the heater? it seems like it takes forever. i guess i am going to cover the grill, what is everybody else doing?

 

[Badunit]

It takes a while unless you can get up to highway speeds soon. Stop and go traffic, though, and it'll be about 10-15 minutes in my experience.



On this heat topic, I've found it difficult to regulate the heat in my truck. Just to keep it warm, the heat control has to be 80% or more to the heat side, it is very sensitive to adjustment (i. e. , hard to make it "just right"), and seems to put out heat differently when it's stopped or moving slowly vs at highway speeds (colder when stopped). I have the dual zone heating. Anyone else have this problem?

 

[Casey Balvert]

Yes, I have the fry or freeze feature as well.

ditto.

personally, i think the dual zone is a waste of space, and totally inaccurate as far as temperature goes.





just chiming in...

My truck takes a while to warm up, I think longer than my other CTD's. The Jacobs Brake is going on today and I hope that will help speed up the warm up at idle. It does help a bit if the truck is plugged in. Man, is it snowing here in Connecticut right now.

Mine is difficult to adjust to the "just right" setting also, but that isn't my biggest complaint. The worst thing is my left foot will get toasty and my right will be freezing, like the accelerator were a block of ice. I,ve looked and the only thing I can come up with is to make a deflector to turn some of the warm air down, directly toward my rt. foot

mine warms up quicker if i run in a gear lower than what I would normally run in

and we are either sweating our butts off or chilly, one click is a BIG difference.

Living here in Michigan, I agree with everything you guys are saying. My feet freeze as well.

I have even noticed with the heat on "panel" it is warmer coming out of the passenger side than it is out of the drivers side.

It warms up in half the distance it took to get heat out of my 93!

Just for comparison - my '02 heats up about the same as my '91 did, takes a good 5 miles... But once the engine warms up, the controls are smooth and very linear in adjustment - but then this isn't exactly the artic, either... My wife's little Mazda 323 is warm darn near before she gets outta the driveway...



A lot of iron to heat up in a Cummins...

 

[ntenna]

Yes, my dual-zone controls are just like the rest described here. They missed the mark on the sliding resistor. A bit more in series or parallel would probably fix it... . just what I need, another science project!



In the TV broadcast business, we call it R&D in the field



But the two zones control makes my wife happy, so it's only a waste for you single guys

 

[LM6000]

I don't really notice this truck taking longer to warm up then any of the other diesel trucks I've been around-it just takes a long time. I definitely agree with everyone on the heater controls and ducting. I just have the regular controls and the heat seems almost impossible at times to get just right. I think you guys are also right about left foot getting heat and the right foot freezing. DC must not have done much testing in colder areas.

All that aside, I wholeheartedly think this is the best truck I've ever been around. The miles are racking up but I just keep driving it.

the reason 03's take longer to heat up, is because they run

leaner, in a diesel, less fuel = less heat. i think they should have

done like v. w and put 3 glow plugs in the cooling system.

I agree with the glow pjugs in the coolant.



But the '03's running leaner??



With more HP than the 2nd Gen trucks the 3rd Gen. trucks have to flow more fuel?



This could get very interesting,,,
