Cold Start DT466

Saw an old thread where CrazyCal mentioned DT466's not having glow plugs...
Fortunately, I haven't needed to start my bus much so far this winter below 30, but the times that I do it sounds pretty rough, then straightens out.

Found a video that pretty much sums up my experience



Is this pretty typical and what I should expect on a cold start?
Sounded like 6 male gorillas fighting over a female!

I know I have an ether button and an empty ether tank, but I'd rather not use any form of ether if I can keep from it.

This is my first diesel, so be gentle

Also, how should I be treating the throttle during cold start?
I'm thinking I don't need to be giving it any throttle, until the rpm's smooth out.

This 1989 international cold start is my exact experience!

I have a diesel 6.2, and am in sunny and warm (even now, in the "winter").. Florida. I'm having cold start problems as well, but my engine turns over but stalls unless the engine is hot enough. In my case, the problem is the idle air control valve. I don't know anything about your engine, but that might be your issue!

oh yeah this is totally normal for cold weather diesels with or without glow plugs they pretty much sound really really rough below 32, the more it drops below 32 the rougher it will sound. People i know around here, their tractors have been running when its below 0 and have actually started to "gel up" while running and sounds like the thing about to die.

Oh yeah.. Loud and shaky!

I took mine out for a camp out over the weekend. It started like a champ even at -10C (14F), but it feels like it's going to fall apart for the first couple minutes! Take it out for a calm drive as soon as possible once you get it started to bring it up to operating temp (unless you need heat to see out the windshield, that is!). Like any engine, it's better to warm it up with light driving load than to let it sit cold idling.

Oh, also... for all those folk with an International E version engine: you can use the cruise control for fast idle in neutral, even cruise has been disabled (like mine). Rev the engine to your desired speed then press both the "On" and "Set" buttons (I think those are the labels?).

I indeed do use the high idle if I need to let it idle.. in fact theres a sticker right o nthe dash of mine that tells me to run it at 1250 and above if idling in cold weather.. fortunately where my house is and where my bus is stored is a couple miles from the freeway.. so when i get it out it goes through a bit of stop and go to get warming and then i usually end up on the freeway with it which will get it up to 175-180 degrees fairly quickly.. (even though I run every heater kown to man on HIGH!!!).. I HATE being cold..

I notice that T-444E is very smooth, not shaky but sure cackles alot while its cold.. doesnt smoke.. but afer i drive it a little it purrs nice N quiet...

the real test will be this week as it will be 0f and ive still got Dino oil in it.. I dint use it today since it was all snowy but I'll probably use it tomorrow.. supposed to be 14 in the morning and then 22 during the day.. then 0 tomorrow night and thursday night and only 12 during the day thursday..

I knew i shoulda got that remote start installed sooner!

I owned a 1978 IHC Loadstar bus that had the DT466 and Allison automatic.

The only times it never started for me was when the batteries didn't have enough life in them to turn the starter fast enough.

I have had that bus sitting in a storage lot for more than three months and I could get in it and start the bus right up, even when the temps were below 32*. Most of the time it rarely took more than about half a revolution of the engine to get it going. When it got way below freezing it would always start but it would start on two or three cylinders and take a while to get the rest of the six all firing on every cycle. It would be accompanied by lots and lots of smoke, lots of shaking, rattling, and roaring. But once it settled down on all six firing every time the shaking, rattling, roaring, and smoking would simmer down to the normal shaking, rattling, and roaring.

Cowlitz that's how our international scouts started in below zero weather.. they had glow plugs but still would only go on a couple cylinders for sometimes a minute or more till they smoothed out.

I kind of wish I had my dt360 up here in Ohio this week to try it. Last trip up it got to 17 and that bus kicked over with just a few seconds of rough idle and only a small plume of smoke.

It's 14 and windy this morning, redbyrd is stored under roof but not indoors.. it's moist air as we got 4-6 snow yesterday.. I want to see if it will run and actually give me warm heat
