Got this one last week 2015 Jeep Grand Cherokee EcoDiesel
I have my 2015 Jetta SEL TDI loaded Stick Car , and my 2014 BMW 328D XDrive! And now My Jeep 2015 Jeep Grand Cherokee Overland EcoDieselNice!
I got An 019 terrain diesel on January 2 . Very nice so far.
Selling 017 cruze diesel stick to a buddy, because the mpg is too good, may as well go large.
67 K 1 owner loaded AIR suspension, 8.4 screen Uconnect Pano Sunroof 20inch wheelsVery nice, Tomo.
How many miles on it?
Correct, in a "part-time" 4WD mode, the front and rear driveshafts are locked together with no differentiation. Must not be used on high-traction surfaces (pavement).Regarding the part-time vs full-time 4WD: on our older Grand Cherokee I remember the full-time 4WD basically allows for the diffs to be open so you can slip some of the front and rear wheels as needed, and this setting also allows for normal speeds on the road.
The part-time 4WD was only to be used for slower speeds and off-road where it locks the front and rear diffs and splits the power evenly between front and rear. It was not to be used continuously, just to help with extra grip.
The diesel Jeeps have always intrigued me a bit.
Hows the reliability on them and what do you guys see as real life MPG's?
That's the same 3l diesel I have in my Ram, although I don't remember if the Jeeps got the 8 spd tranny. Engine can have some issues, but then we're used to that! Make sure to take it in for the updated AEM flash. Supposed to be an improvement over the original EPA mandated crap. At 34k miles, I'm around 22 mpg lifetime with best tank at 27.Only had it a week....will let you know
Rrusse11, I had an’06 CRD Liberty and loved it...except the transmission. Dodge/Jeep went cheap and put a plastic stator in the 545RFE’s converter. Went through three TCs under warranty. Would have kept it, but the issue hadn't been resolved when the warranty ended. Afterwards, the answer was to replace the converter with a billet and furnace brazed unit...most CRD drivers got one from SunCoast https://suncoastdiesel.com/c-1390072-diesel-converters-dodge-cummins-545rfe.html. I’fe you want to make it last and keep the Mrs. happy with the auto, I’d highly recommend giving SunCoast a call and asking about the converter. That VM. R428 is a beast...it’s what most of the London black cabs of the day had in them...very reliable engine (when the EGR was addressed, as is on yours)."If your transfer case shifter offers only 2Hi-4Hi-N-4Lo, you have
the Command-Trac (NP-231) Part-Time 4WD system." Rob
That's the one! And I'm getting a handle on the differences, part time is
indeed intended for occassional slippery surface use. If that snowstorm
hits, use it for getting going, and then use fulltime for driving around in it.
I've managed to find a manual online, which I've downloaded;
http://colorado4wheel.com/manuals/Jeep/KJ/
Got an oil change kit and a new MAP on the way, the PO made a point of
telling me to clean it regularly. I'll swap the old out and have a clean spare
on hand. Service interval on the oil is 5-6k, although I'm tempted to run
it 10k like the TDI. Don't know if the "truck" oil is really any different,
I did manage to find a gallon of Rotella T6 5W-40 at the local Walmart.
The oil pan has a valve installed, which my guru shuddered at, he doesn't
like the possibility of it getting knocked off. It does need the skid plates
put back on, not that I bought the vehicle for offroad use, but any kind of
oil pan protection is a good thing in my book.
The manual swap would be a good thing to do, but the Significant Other
won't drive them, and it's supposed to be "her car". She's comfortable
driving it, I'll be sure to impress upon her the cautions on the 4wd system.
She allowed as how she's always wanted one, but her mechanic father
wouldn't allow it, said she'd likely flip it. Growing up in the snowbelt,
Maine, 4WD was a desired option.
I'll carry on with the full service, the rear brakes will be interesting. The
parking brake has shoes on a mini drum as part of the rotor.
I'm assuming the TB has an age limit like our TDI's. Got good documentation
it was done 4.5yrs ago with idparts quality kit, 45k. So I reckin I'm good
for at least another year and half. Good video on youtube about the job.
Involved!
I'll get a hold of some quality synthetic gear oil for the diffs and axles
and change all that. Fingers crossed that for it's low mileage intended use,
it'll keep going for a while. At least all the running gear is easily
sourced, and the more I listen to the motor, it's got a chance of going
another 100k without too many issues.
It has the 8 speed and I have all service records it is nice sadly been sittor the last 2 months can’t really go anywhereThat's the same 3l diesel I have in my Ram, although I don't remember if the Jeeps got the 8 spd tranny.
