Thread: Turbo cooling D4 3.0

I always thought it was enough, once at the in town from a longish drive, the 4-5 mins at 50kph putting from the town limits to home.

I do much the same as Robocop. Drive slowly the last few klms from home careful not to over rev.
Also, once I'm home, I get everything out of the car that I need to take in etc, then turn the vehicle off.

Always done this for safe measure. Don't believe in switching it straight off.

Cheers, Craig

I did try & edit my last post but it didn't work.. Anyway, I usually turn the engine on a few mins before leaving to get the blood flowing, and the heater for swimbo..

I don't agree with letting the vehicle warm up prior to driving off.
My father in law who is a diesel engineer & mechanic, advised me to drive the vehicle immediately after starting it.........but drive it gently until running temperature is reached.
This way, the oil will get pumped around the engine quicker.

Makes sense to me. Been using this method for 20 years .

Cheers, Craig.

I don't disagree, my dad does the same thing. I think I read on this forum back when I had my defender where a bloke worked for CAT or similar & mentioned a carbon build up if left idling for too long. My problem is everything in town is within a 5km radius unless I go to Griffith or Wagga. Lots of short drives.

thanks for the replies fellas. Just wanted to see what everyone else does.
I have an old turbo diesel 4 runner that i drive around slowly after a workout to let her cool. If I cant do that then i just let her idle for a few mins..

I let all our diesels 'run down' it's something you learn on the farm, however with all the computer whizzbangery i think the engineers would have built something into the 'intelligent ignition (push button)' stuff to prevent the car turning off with hot turbo's, also what about the 'intelligent stop start' on gaylanders (Freelanders) and gayrangers (Evoques) how does that not fritzel your turbo???

I agree to your theory to a certain extent. I recently brought the wife a BMW X3 and it has the same 'stop / start' function. When you pull up at the lights etc, the engine turns off. You can override this function by pushing a button beside the start / stop button.
Still don't agree that any turbo charged engine should be shut down immediately after driving.
Call me old school, but for piece of mind, I'll keep doing what I'm doing.

Cheers, Craig
