Warm-up procedures when starting from a cold start?

I know a bunch of guys who fire it up and hammer down whether it's -60 or 95 degrees outside. I'm a firm believer in at least a 10-15 min warm-up, high idle. I'd be pretty mad if someone woke me up out of a dead sleep and started working me before I've had my morning coffee and chew.

 

Yea. A couple years ago I had a starter short out and kill the batteries. Company sent out some to pull start it. Just hooked the chain and got the truck rolling while I popped the clutch and it fired right up. Drove it 3 hours back to the shop. Only time I've used the fire extinguisher as the short caused a fire in the starter....

 

Funny….. that’s something my wife “used” to do in our younger years and never had a problem. Right from a dead sleep was never an issue. Today…… it has to get warmed(worked on)up before it fully functional to get moving.

 

Haha I hear ya! Mine left about a year ago so now I stock up on hand warmers LOL

 

no comment.

 

Lord, be with the starving pygmies down there in New Guinea. Amen.

 

Never had an issue, start the truck, let it idle for 2 minutes or build up the air then move.

cummins and DD both said idling to warm up isn’t needed as people think.

been doing this same thing since I started to drive.

 

Good question but I guess as long as there's enough power to fire the injectors it should start. Only needs enough to turn the alternator a few times. I've never tried it on my E model so I can't say with 100 percent certainty though. My next truck will have a mechanical CAT.

 

I have never extensively idled. Easy on them for first few miles. My oil samples have come back good unless I have had a injector start streaming.
DD15/16 do not like idling for long periods.
Why I have mentioned the newer engines need to be operated differently.
I have a apu on my trucks. But they are generally shut off even in -30 or so.
They still start just fine. Wait until oil psi builds increase rpm a few hundred wait 5 min and ease on down the road.

Like you said even Cummins doesn’t like long idle times. But old habits die hard

 

I think Detroit Diesel also says and probably all engine manufacturers. When engine is cold don't go directly to hard pull like pulling a hill and take the engine from cold to maximum engine temp. Because the engine parts heat up at different rates. Like the other post said it's not good for engine block to go from such extremes. I know of a couple truck stops at bottom of big hills and I bet many drivers just start up and to up the hill.
