Ecodiesel Eco-nomics & Issues

[AZ-Chris]

Well, I think everyone would agree that, once modifications start taking place, problems/issues are bound to occur and all bets on reliability/operability are off . . .

It shouldn't. And it didn't used to be that way.

My old CJ7 could handle a healthy V8 swap with a big winch in front of the grill all day long anywhere I would take it. And that's on bigger tires with deep gearing and various armor bits installed.

The bigger grill and radiator, along with room for air flow around the engine was night and day different than the modern Jeeps.

The modern Wrangler needs more cooling capacity no matter how you slice it.

If I get the diesel, first thing I'm going to do is fill it with rocks and head over the Beartooth pass.

I mean, while you're up there, might as well hit up the Morrison trail to bring home some rocks for the yard.

Morrison trail... Gotta look that one up!

Speaking of which, where do I find a list of MT Jeep trails?

AltaVista?

My old JK with the 3.6 derated on me coming up to the Eisenhower tunnel on I70 one hot summer day. I wasn't even towing. And I'm not alone in having this happen.

While maybe not as common as the diesel, derating happens when you're really pushing a modern Wrangler on a steep mountain grade on a hot day regardless of the engine you're running.

The number of folks regularly driving at 11,000 feet is very very very few.

Where are you in Montana? My rolled XJ avatar pic to the left is above the Madison a little east of Norris. I went to school at MSU.

Not sure where you'd get a comprehensive list, but I always enjoyed poking around dirt roads all over the state.

If you're near Billings, or more accurately, Big Timber, check out Independence, MT. It is a ghost town on the north side of the Beartooths. You pass Natural Bridge Falls, which is really cool, then just keep following the Boulder River south. Lots of campgrounds south of the falls, and eventually you'll get to the trailer parking & guard house at the start of the "Jeep" trail. Good camping or do-able as a summer out-and-back in a long day.

A lot of my old trails around Bozeman are now closed to vehicles, or at least over 52" i believe. Others have become subdivisions.

Now we're drifting WAY off topic! Hahaha!

I'm so close to pulling the trigger on the diesel. I just can't get the "you should have known better" voice out of my head.

Buying something with known issues goes against my obsessive compulsive nature. But I guess if I read about literally any vehicle on the planet, it will have issues.

It would be nice if Jeep would fix it. Nothing like a $60k vehicle that needs upgrades.

They didn't design the JLURD to run 37" tires, with a lift, tow a trailer, and do it over a mountain pass. It's fairly simple. That's a tall task for a diesel jammed into a small engine compartment. I don't understand why people think you won't run into any problems with those extreme variables.

Keep in mind many people AREN'T experiencing issues as well even with some or all of those variables. I'd bet money a stock JLURD or one on 35" tires with no lift would be fine most of the time.

I haven't experienced the overheating issue, but I also haven't driven overloaded over mountain passes yet.

And that right there ladies and gentlemen sums up most of the engine issues. Overloaded.

I was on a similar boat as you, but I was dead set on the 2.0T but I was debating the diesel. All the emissions stuff was putting me off, but I ended up just getting the diesel anyways because of the 5yr/100k warranty gives me some peace of mind.

I never even test driven the diesel yet and my 2022 diesel should show up at the dealer within the next 2 weeks ???

Alright, what do I do for a lift if I go with the diesel?

Lots of others are trying to talk me into the XR package, which isn't a diesel option. My other contender is the AEV 2.5" lift. ....seemingly sends you down a black hole of thousands of dollars of other upgrades.

Wish they would do a XR package for the diesel and set it up with the right size gears - maybe it wouldn't overheat.

Mopar has a 2.5" diesel specific lift that has great reviews. The best part is it comes with Fox shocks and is affordable.

I just bought the diesel on a factory order having never test driven the 3.0. I only test drove the 2.0T and the 3.6. I knew right then those engines where not for me. I picked up my diesel outside of Nashville and drove it back to Austin at 80mph and all I can say is that I am in love with that engine. I am slightly over 1000 miles now and my average MPG is a whopping 25mpg! 940 of those miles was going 80mph! And it does have torque! Bottom line is it is just fun as hell to drive.

I assume the cold air intake option won't do anything to help the engine with overheating? 99% sure answer is no, but I better ask.

You're better off puting the money into the vented hood, vented inner fenders and some better fender vents.
