SO, what should I know about this NEW turbocharger? Is it improved over the old one, the same, something completely different? What can you tell me about it?

Thanks![/i]

IIRC, the turbo on our CRD's is a Garrett VNT 15. I've only heard of one or two turbo failures on this board, so if it was common it would be covered quite a bit more extensively here. "gmctd" has a write-up on an SEGR install in the tech section where he also includes some pics of his turbo, pulled off the Jeep and broken down. All the specs are there.

Just my 2 cents, but I think always allowing your turbo to cool before shutting down the engine is a "best practice." I don't obsess about it, but after putting it in park I turn off the A/C and let it run some - depending on how hard and at what speed I rode it - then shut it down. This past weekend we had a "CRD Workday" locally and another member commented how there was no oil around my turbo return line. (Our turbos are oil-cooled, so there is a drain line running from the turbo housing back to the engine block) He said his is all gunked up, as has been the case with every other CRD he has looked under. I asked him if he lets his turbo cool down before shutting it off, and he said no. It may not make a difference, but it is a little piece of mind to know I am at least not contributing to any oil coking in my turbo or return line.

Congrats on the new CRD.

question about letting the tubro cool. I am aware of this but am not sure how long to do this. I make an effort to remember. what I do is park get my seat belt off, pick up my cell phone and unplug it from the charger if plugged in. change from sunglasses to my regular ones if its sunny out, gather what ever I may have on the passinger seat to take inside. then turn off the engine. usually I have one to two of those things to do other than unbuckeling..... so I'm letting it run 20 to 30 seconds after I put it in park also I coast in to my driveway not pushing on the skinny pedal. If I think I have been driving hard I wait a bit longer. IS this enough?

I'm driving almost 2 blocks off the main street at 25mph or less and its mostly down grade too. the major street to my neighbor hood has a speed limit of 35. my daily commute is some on back roads and some on multi lane roads with traffic lights.

Lets go back a mile or two Is your home at the bottom of the freeway ramp where go from 70 to a stop or are you driving several blocks into your neibhore hood through 25 mph side streets? In the first example your turbo is red hot and in th second it's have a few blocks to cool down
