6.5 warm up?

[madcarson]

what's req or best warm up time duration? In summer is same as gas job or what? thanks just like to know whats best for motor!:confused:

[madcarson]

no one has any opinions?:eek:

don't warm it up, just drive slowly until the temp guage shows something.

I know a guy that is a master of the 6.2 and 6.5's and has owned them since the beginning.he says do not move these trucks for at least 10 min.minimum warm up and short trips (to the party store) are the worst things for these engines.I work as a master tech. at a big truck shop and the manufacturers recommend warming to operating temp.before even driving.it puts alot of stress on diesel's if they are cold.I hope it helps

Install a Line lock and Hit the gas pedal, till it smoke :D that will do the warm up

If you use the run in specs for any engine you don't let them idle too long as they don't lubricate adequately. I would rather drive slowly to warm up than let the engine idle unlubricated.

i would idle the engine for a few minutes so that way your turbo has some time to get up to speed on wind up that way you don't blow your turbo up also.

Start it, wait a bit after full oil pressure to make sure the entire engine is getting oil. Then drive the damned thing. If the film strength in your oil isn't good enough to allow this, then buy better oil. There's too much proof and fact to support both side's argument to ever come to a real conclusion.

Just wait until it's warm before you get into it. Grancito's right. What's the difference between 700rpm(idle) and 1000rpm(gently driving) to an engine??: about 30-40psi. I think I'd want better and fuller lubrication than being scared of undue metal fatigue. But hey, my engine just blew up!!:eek:

But that wasn't from oil. Actually it commited suicide when it found out how dangerous and sinful diesel particulates, and non-egr engines are. It must have been listening to NPR on that Prius' radio next to me on the interstate. I got a bit close to it, and almost sucked the whole car into my turbocharger!!!:rolleyes:

...have oil pressure and a smooth idle, you're ready to rock....if you boys north of I-20 wait for "operating temperature" you'll still be waiting next spring....

Another opinion,diesel pistons are very dense material.This means that they (like a forged racing piston) will expand more when warm.So,a cold piston is really kind of loose in the bore untill warm(think wobble in the bore).But,as stated above,oiling can be a problem during cold idle.My Mopar is forged and set up loose in the bores.It sounds as if its gonna scatter in the morn for about 2 minutes.6.2/5s are slow to warm up anyway.

i always let mine warm up for any where from atleast 10 minutes to 20minuts...... only if its cold enough tho........ if its above 40* ill start it let it run for a minute or 2 just to build oil pressure.......

if its below freezing i let it run for a long while......never had any problems lettin them idle for long times.........


now w/ my D-Max even if its 50* i need to let it warm up my tranny fluid otherwise it wont hit OD.......:mad:

Your Duramax is designed to not go into o/d untill coolant temp reaches 105 (could be a bit off on that #) that motor stays in open loop(running of programming) until warm,then goes closed loop and takes the actual reading from the various sensors and adjusts for ambient air temp,speed ect.

GM engineers recommend 30-45 seconds after oil pressure comes up before you take off. They also say take it easy until it goes over 100 degrees.

Just a little bit I remember from my schools days.

i have a early 99 and run 0-40 all year round i usually start it just b4 i leave then drive it gently 1000 rpm till it starts to show on guage then as temp pises drive faster

[flattire]

i have a aftermarket throttle setting when i start the truck it idles at 900 to 1000 then drops as wotor warms so i kick it to first notch it stays at 1000 when i leave i shut it of has worked great

10 to 20 min.'s sounds about right. remember the fluid in the engine isn't the only thing that needs to warm. pwr steering, trans fluid are also things that need to come up to temp. seals and o'rings do not like fluid pushed against them when they're cold. they tend to fail, allowing fluid to pass by.:eek:
