I know its good to allow your turbo to cool down to around 300 egt when your done driving, but what about short stops? Say like gas stations or under 5 minutes before you start up again. Will it hurt anything if you dont let it cool down if your gonna start it right back up? Or what if you forget & shut it down, can you just start back up & let it cool?
I figure its not gonna hurt the turbo if it sits heated for a few minutes with the engine off or am I wrong?

I always give the turbo atleast 2mins cool down for normal driving, and for hard driveing i give it atleast 5 to 6mins cool down but i baby my turbo when it comes to cooling it down, do u have a pyro meter?

a Remote truck starter is a must have i think, cuse you can turn the key off and take it out and lock your truck and walk into the house and your truck will coutinue to run for 5mins or what ever you set the timer too, then you waont have to worry about not giving your turbo enough time to cool down, the unit price is about 260bucks installed.

Where do you get a price like that? The best I could find so far was at best buy and it was $480.00+ installed.

I have the isspro cool down timer, I bought it for 140 bucks from diesel manor. It is awesome, you can set it to whatever temp you want it to shut down at and walk away,, no more guessing how much time to leave it on

I have the recon gauge & a bulldog remote start with a turbo timer, but I was just wondering if it was necessary to set it for short in/out stops or the other questions I posted.

Oh yeah, sorry, I just reread your first post,,, personally, I kinda play it by ear, if it hasnt ran for too long, and is only say in the 4 or 5 hundreds I will shut it down,, I dont think that it is too bad for it that way,,, but if it is really permeated with heat, say after a hard run or a highway trip you should cool it down

do you have a wed site for that cool down timer? 140 bucks sounds nice

Im happy with Howards TT, but I dont think he makes them any longer...

I just hit the button and hop out wherever I stop. Even if its just down the street, I let it cool for 2 minutes when I get out. And 2 minutes is plenty when going down the highway empty for a long trek. I only use 4 or 6 minutes when ive been towing.

This is going to start a flaming war but..... Don't worry about it. If mine's around 600deg I'll let my remote start/turbo timer take care if it. But I have to be really pushing it for it to be that hot when I stop somewhere. For normal everyday driving I've noticed that just by slowing down and turning into a parking lot it is already cooled down to around 300 or 400 degrees, especially with a 6spd. With my turbo timer each time you press the button on the remote it idles for 1 min (2 presses = 2min and so on up to 5 minutes) However I've noticed that even towing 1 minute is more than enough. If this was as big of an issue as everyone likes to make it out to be, think of all the turbocharged vehicles (gas and diesel) that would need new turbos everytime they changed oil. As always it's your truck and you can do as you wish, but remember it's a truck not a newborn. Every turbo I've seen fail was not from shutting down hot. (2 broken shafts, 1 broken thrust bearing, 3 exploded compressor wheels)

RamnUtah,
My '07 has 3400 miles on it, and I'm doing a 'variable' cooldown. After the truck is up to temp and I've been on the highway awhile I let it cooldown for 2 minutes. But if I just go across town and it's up to temp but it hasn't been running hard, I usually do a minute. I do this mainly due to reading the chart in the owners manual about cooldown. Oh and no EGT gauge yet.

Jfaulkner,

I've wondered about what you hit on. My highway driving is usually followed by 2 miles of in-town before getting to the driveway or office parking lot. So I figure the slower speed operation is a 'warmdown' period which lets some of the heat dissipate, so maybe shorter 'cooldowns' in the driveway/lot could be done? I wonder as the manual also has a paragraph about excessive idling (something about 10 minutes per hr of operation).

Anyway, going to add an EGT gauge and then just shutdown ~ 300*

Cheers
Joe

Cooldown for me is keeping the rpms down low and taking it easy a couple of minutes before I park. If I've been on the interstate or highway mashing on the motor I might sit there for a minute and let it cool down. I've always done this on big trucks too and never had a turbo bearing cook.

Ram, you don't say, do you have gauges? If not I'd get some, you'll need them eventually once you get bitten by the bug!

Diesel Manor talked me out of a timer, if you have a pryro you'll know how hot it is.

I haven't towed with my truck with the latest mods etc, but when I back into the spot at work or park in my garage it's down to 300, anything under 400 is fine I hear?
Never had to sit a wait for it to cool.

Save your money, buy something more fun!
