I’ve had mine for two years and it does great. I own 3 semi trucks and what Chevy did with the EGR and after treatment is very cool. They’ve simplified and made those systems much more reliable. Having recirculation after the filter, so close to the turbo, and no hydrocarbon injector eliminates so many problems. Also, I’m not sure many people have owned a vehicle long enough to service something like a timing belt. I had a 2003 VW Jetta that needed a timing belt change. You have to almost disassemble the car to get to it and it takes a mechanic almost a whole day to do. With this belt, 150k mike service, you drop the transmission, replace it, bolt it back on, that’s absolutely easier than what you have to do on many other vehicles. And the coolant system, on an 18 degree day I can warm up for 3-5 minutes, drive about 2.5 miles, and I’m already approaching full temperature. It gets hot almost as fast as a gasoline car. I have nothing but good things to say.

A timing belt job on a 2015 Jetta TDI is 4.8hrs. 12hrs is not bad for something that has a 150k/15 year service interval anyway, especially in a truck that saves you $10-13k in fuel costs over that same time.

Even after you pull the transmission, you'll still be replacing two chains and a belt from underneath the truck with the engine against the firewall. If you're going to do all that, you might as well pull the engine. Anyone who thinks this job would be easier than replacing a front timing chain is nuts. And a belt driven oil pump? If that belt ever brakes, it's not going to give you any warning. If it brakes you'll have to pull the engine anyway because it'll be junk. The only reason to design something like this is to sell parts and service. They are building vehicles that you have to take it to the dealership for any work or buy another truck.

I don't think the transmission bell housing area, after transmission is removed, is "against the firewall" and the belt is in the lower half as well.. you wouldn't have to remove the chains to change the belt.,, If the chains fail the engine is coming out anyway.. pretty much guaranteed. I don't know if the oil pump belt is as big a deal as people are making it.. engines with belted timing belts can be a pain it the butt and expensive to change as well. It's one of those things that after you reach a certain amount of miles you want to bite the bullet and pay to replace BEFORE they fail.. I don't think you would want to chance the oil pump belt failing on this either.. not because of "burning up the engine from no oil".. I think I would be more worried about what's left of the belt going up into the timing chain and causing catastrophic damage.

[@preachers4135]

Dude, did you pay any attention? It doesn’t have a timing belt. It has timing chains, two of them, in series. Fist one drives the high pressure injection pump, second one drives the cam shafts… (Why in the heck did they design a Diesel engine with DOHC when the main benefits of the complexity is only realized at high RPMs which diesels don’t run at?)… I digress, THE BELT YOU REFERENCED DRIVES THE OIL PUMP and is oil bathed. When, not if but when, this belt fails it will MOST LIKELY result in significant engine damage due to rod and main bearings being starved of oil. Best case scenario is to replace a belt before failure but as a professional mechanic I will say the average consumer will have long forgotten this critical service when a vehicle reaches this mileage. 2nd best case scenario when an engine losses oil pressure is immediately shut the engine off and coast the vehicle to a safe location away from traffic. But consider, how much of our driving is on busy freeways with no safe locations within coasting distance? i.e. construction zones with barricades. To add another possible point of failure this oil pump is variable displacement which depending on design details and quality of components used may work out fine but could also easily be this engines achilles’ heel. For those that may not know: When a traditional timing belt fails on an interface engine the engine immediately stalls and significant damage occurs due to valves colliding with piston crowns. When timing belts fail on non-interference engines the engine also immediately stalls but most of the time no further damage results, replace the belt and continue on.

I'll give em credit for figuring out how to get the EGR after the DPF.

Also, good choice with I6, this is a big NVH advantage over the Chrysler/Fiat V6 and certainly improves packaging of the SCR, DPF, & turbo.

Why does it even have EGR? It’s been proven that robust SCR can be used to eliminate EGR, EGR coolers and all the associated re-ingested soot nightmares.

Its not the EGR by itself getting those clogged up, it's the PCV valve that's not a service item for most dealers that cover everything in fine oil mist after 30-50k miles of life, which then it traps the soot on the oil.

And for the love of Pete, why put a belt on the oil pump when the timing chain is RIGHT THERE? Don't worry, if it fails, you will be warned and be able to stop; meaning you will instantly loose oil pressure and get a warning that your bearings are eating themselves as you take a few seconds to read the warning, slow down, pull over, and shut it off. Then tow it to a shop where they will have it on a hoist for 2 days and charge about 2 grand to change that stupid unnecessary belt and hope your motor is still good. Rant over.

Definitely sounds like they thought of everything to keep factory trained mechanics with specialized tools fully employed. But at least they made it so they can get repairs done in 40 hours or so. I had a 2004 chevy 3500 work truck that blew its heater core. It took the dealer 3 days and the complete dismantling of interior to replace a $50 part. The labor bill was over $1000. Smart planning by the engineers

Buts that's every heater core in every vehicle tho.

[@mikegoff7506]

That's probably true in all modern cars... I'm a dinosaur worked on a lot of pre computer, pre plastic cars over the years. A heater core was a couple hour project

[@TheChrisricciardi]

Yeah, nowadays they just buy another car. Haha.

Reading a lot of the comments I seem to notice people did not understand that the 'wet belt' has a minimum 150,000 service, that does not mean you have to service it at 150,000 miles. It could go way beyond that amount...take a few moments to watch the video again and listen to him.

No, you don't. But even if you do, you're only likely to service it once, maybe twice in the engine's lifetime. Not that big of a deal IMO.
