Thread: Turbo cooling D4 3.0

dultim8, I am lead to believe not to over rev a new engine, especially a diesel, however dont be afraid to work it.
I was a bit weary about towing my 2.2 ton boat on a four hour trip not long after I bought it (only travelled 1,500Klm's). According to my father in law, its the best way to run it in.

Once the engine is run in, certainly dont be afraid to 'blow the cob webs out' every now and then. Just make sure that the engine is at running temperature.

Cheers, Craig

I drive side loading garbage trucks for a living and these vechiles work load is rated as severe service, hard on transmission, engine and especially the cooling system due to the low speeds.
We blow turbos up every now and then but According to our mechanics the best way of extending their life is regular oil changes. If the vechile has been working hard and hot idling down for a couple of mins in theory should help prevent the oil from boiling in a hot turbo, but it dosent seem to make them last any longer.

More fun to find a big steep hill with lots of dirt/sand/mud etc stick in 2 low and haul up it, then let it idle for 2 min, turn around go down and do it again until you are happy. Could take all day !!!

Now that is a great excuse to get you new D4 dirty.

You'd have to be driving auto-cross style to get a turbo hot enough to need idle time when around town.
Even from a 100km/h flat cruise, pulling to a stop will see your EGT's low enough to not need any idle down.

If you get to the top of a mountain, don't shut it down straight away. Not just for your turbo but your cooling system. Good times at ski fields watching cars start to boil a minute or so after they've been shut down.

so how should i run it in if i dont have any big hills nearby or a boat to tow around???

Don't wrap it up in cotton wool. Use the load pedal but don't thrash it.

Brett....

Isnt this in the World Famous FAQ??

I'd think it would be in the owners manual.

Hi Pedro

I had a look in the FAQ located here. http://www.aulro.com/afvb/d3-d4-rrs/...4-rrs-faq.html
I could not find anything about running in a new vehicle.
Would you please be able to point me in the right direction to find it?
