Turbo Cool Down

Hello,

I have read a few messages talking about needing to let your turbo cool down before you shut the engine off. I have not been able to find any information on how to monitor the turbo temp., or if you were able to monitor the turbo temp at what temp it is safe to shut off the engine.
Does anyone have any information on this subject?

Thanks
John

I just make sure my EGT is back down to 300 degrees preturbo before shutting off the engine. I'm not sure what the actual turbo temp should be, but I've always been told as long as the preturbo EGT is back down to 300 your cool. Hope that helps a little.

That the rule I follow too...If you dont have a pyrometer Just let the truck cool down a couple 30 seconds - 5 minutes depending on how hard you were driving it. I got used to waiting for it, doesnt bother me knowing that im extending the life of my turbo :Thumbup:

You can add a turbo timer/life Saver and make it easy. The 300 deg is a good general rule, and you need an EGT gauge for that.

I have a remote starting alarm set @ 10 minutes, and I use it to cool down the Turbo once I reached my destination.

Ditto; mine's only set for 3 minutes though.

First let me offer a shameless plug for our Turbo Temp Monitor:

I don't actually have one in my truck (haven't gotten around to putting one in). One suggestion I learned back when I drove Freightliners: Rev the engine up to ~1000 rpms (in neutral), to shorten the cool-down time. Moving more relatively cool air will cool the turbo down faster.

It seems pretty hard to get my truck to drop to 300 on a pretty warm day. Is alil over 300 ok. I mean as long as it's got up to a few mins to idle is it ok? I was looking at this.. bottom.
