I have heard differant stories. Do you need to let the engine idle for a minute or so to let the turbo cool down before shut down or just shut down? Confused

I let my truck run for a minute or two.  I don't get to do it all the time, but I do it as often as possible.  I let it run for 10 to 15 minutes if I haul something for a long distance or if what I'm hauling is heavy.  I let it run for a while if I dorve a long distance also.

It's best to add on an EGT gauge and then let the exhaust cool to a certain temp before shutting down. But if you are just cruising town I don't see it hurting to just shut down.

if you are just driving around town you dont need to let your turck idle but if you are driving at high speed like the highway or if your towing something you should let your truckk idle for a few mins because the turbo need to cool of and be oil

let me give you the technical reasoning. the turbocharger has a steel shaft, that spins inside an aluminum bushing. steel retains heat better than aluminum, therefor it doesnt "shrink" as fast as aluminum after the heat is removed. so if you are working the engine hard and you stall or something, if you dont restart it right away the bushing will shrink onto the shaft leaving no room for oil to lubricate. the main purpose of idling before shutdown is so that both the shaft and bushing are as cool as possible with the engine running so it doesnt sieze up. it doesnt take long only a few minutes, the 15 minutes that 7.3 uses is probably excessive but better safe than sorry.

You can also refer to your owners manual. The creators of the Dodge manual suggest 45 seconds after freeway and 30 seconds around town.

technicly you are supposed to let the egts come down to 200-300 deg now anyone running a commonrail cummins has probably found out this is damn near impossible if it was over 70deg outside so i would let it come down to 400. Now my 2001 cummins will cool down to under 300 in seconds.
