Well It takes a lot to get a diesel started. Diesels generally run cooler then a gas engine. Things I noticed with my 6.2 GMC (shut up norm!) and my John Deere 950 tractor were/are......

In winter they run cooler and cool off fast when shut down. Keeping them running will keep them warm. A cold diesel is hard to turn over and start and you may not get warm air out of the defrosters.


My John Deere manual says to idle the diesel for a few minutes after hard work to allow it to cool.


I think on the bigger engines it takes just as much fuel or more to get them started. Not to mention wearing out the starter that is required to turn a 16:1 or more compression engine over to start it.

I also think you really should allow them to idle some to cool the turbo bearings down and in between stops its easier to just let them idle to cool down and then take off and go again. We are supposed to let the diesels idle 10 minutes or so on our Locomotives to cool the turbo down.

I am sure Doug H will have some other things to add that go with the big rigs.
