How long does that normally take and what sort of driving have you done in the last minute or so before you stop?Quote:

Crank handles used to be useful once, but are a bit useless on modern engines.
I've never warmed my turbo up or cooled it down on my Tdi and it's still going strong after 14 years. Pat
Can take from no time at all to a few minutes if stopping at highway speed on a hot day

I have mates up north running road trains that wont switch their trucks off for days(Roma Qld to Broome W.A.) as the turbos run red hot all the time
Another option which is less known is the fitting of a turbo saviour, basically it is a spring loaded filter setup that is hooked into the turbo oil feed line.under normal oil pressure the spring compresses and holds oil in the filter, when you shut the engine down it slowly releases stored oil into the turbo. I have these fitted to my excavators, with good results. Modern diesels in 4wds shouldn't need any real cool down time, idle into the drive give it a few seconds and you should be right.
