PPE 3.0 Duramax Diesel Charge Air Cooler Installation and set backs

[@BCD0711]

I’m super eager to see what SEMA will bring as far as new 3.0 parts! This is a great start.

[@TJNC1976]

I'd like to see the outcome of this installation. See if any HP is gained and how it affects the MPG

[@thechevysilveradotec]

Love to see a tech installing this as I would myself ! Can’t wait to read all the comments

[@romadzero]

I can’t wait for your numbers. I decided to order one!!

[@jepunit12]

Can’t wait to see the aftermath of this installation. Bad ass man!

[@ThunderGod1388]

We’re eagerly waiting!

[@DemonWorks]

Upload tonight. Thanks for your patience

[@DemonWorks]

It’s up !

[@keithasche]

I would definitely say that if you do this work, and you want to do the intake tube as well, doing that while the charge cooler is off would be easiest.

[@seankelly894]

I have already installed this, waiting on the ppe intercooler…where does the coolant recirculate back into the charge air cooler

[@DemonWorks]

Front most radiator is for the charge air cooler, there is a pump attached to it that flows the coolant through the charge air cooler then back through the charge air cooler radiator.

[@seankelly894]

@@DemonWorks Im tracking, however the charge air cooler hoses run from the overfill to the charge air cooler then out. I dont see any return line...just trying to gain a better understanding.

[@DemonWorks]

@@seankelly894 the reservoir has a hose into it and out of it. The whole system is in a loop.

[@The71chevyman]

Would like to see what this does for the fuel mileage..

[@nickchesko1719]

I recently just purchased and received the PPE inter cooler for my truck but I am confused on how the inter cooler will self fill/replace the coolant on its own. Looking at the cooler, the coolant reservoir is lower than the fill hose(liquid goes down hill not up hill), wouldn’t this not allow the cooler to self replace like the stock cooler? The stock cooler hose from the reservoir is flush so any coolant loss will natural replace itself. I watch how you had to lift the coolant reservoir up 6 inches or so to fill the cooler up, that doesn’t make sense to me unless the unit has a pump that pulls the coolant up into the cooler itself. Is there something PPE told you on how the unit works in that matter. I would hate to put this on and later on over heat due to no coolant in the intercooler. Or every oil change do we have to raise the reservoir up to refill the cooler? Sorry for the essay but I hate to ruin my truck engine over this. Thanks

[@DemonWorks]

Understandable, there is a pump that runs the coolant through. Fill the way I did and you are good to go.

[@johnspurrier0001]

I would be extremely interested in the numbers. While a larger surface area will lead to faster heat dissipation, a larger unit does not necessarily equate to larger surface area. I'd be concerned the larger housing on the replacement unit is thicker, and causes a heat trap. Those engineers at GM are pretty sharp when it comes to efficiency and effectiveness. Granted, regulations may require them to leave a little left under the hood l.

[@MrWeaponlord]

Is there an oil catch can that works on the lm2 or lz0?

[@ryanlogan2911]

The one I bought Black Friday I put in 2 days ago. About to do my first heavy tow today. PS they tigged the PPE logo on backwards so it looks like upside down EPP

[@DemonWorks]

Yours is upside down? Or mine and I haven’t noticed 😂?

[@acejacks00]

Maybe I missed it.. where did s&b go?

[@DemonWorks]

It was a test fit. I’m not a fan of the S&B., will do some testing in the near future with it though.

[@The71chevyman]

Has anyone tested any coolant additives to see if that can also improve the efficiency of the intercooler? Would be interesting to see if they would have any affect. With the stock intercooler and with the improved intercooler.

[@DemonWorks]

In my past research of coolant additives, they do absolutely nothing. I have bottles of water wetter sitting in my garage as well, with no eagerness to pour in.

[@ryanlogan2911]

Any idea how hard it is to change the intercooler radiator? A road rock from the truck in front of me knocked a hole in mine today.

[@DemonWorks]

Oh no !!! The whole assembly of radiators needs to come out. Not. a quick job at all, unfortunately.

[@anthonyobrien36]

I have a 2021 Sierra with a 3.0 I have the banks pedal monster with the Idash gauge. 3.5 inch lift and running 35x11.50r20. Is there anything you would recommend doing? I see you videos about the s&b Cold air intake and how you didn't really see any gains compared to the stock and also the intercooler by PPE. I'm waiting for the derringer.

[@jttribe7683]

Great video dude! By chance have you fou d a good eadier wite pass through for the LM2

[@jonbacon8013]

My charge air cooler pump is leaking oil the connector’s leaking oil into the pump but I’m two weeks on back order GMC idiot what can I do? It’s under warranty yet can I talk to Tim? Thanks.

[@ryanlogan2911]

What’s the verdict?

[@ChadHitson]

What’s the expected gains from this intercooler?

[@DemonWorks]

Lower intake air temps.

[@jonathanmelendez2377]

And ??? How she sounds?

[@thehonestguyreviews4516]

Comon dude, we want to see it in operation and you driving it

[@DemonWorks]

I understand, this was installed Saturday night then video edited right after. I am working on the video you are after, like many others, just not enough seat time yet.

[@joootooobboosheet2486]

Your video is 1 year old. What differences have you noticed in your truck since installing this part? I'm curious to know if it's worth the $1400 to change out my charge air cooler.

[@loudmouthgamer873]

Will all of these ppe mods that you have done to the turbo parts did you have to adjust the tune at all ?

[@DemonWorks]

There’s no ability to modify the tune at this point. The mods I have done are meant to assist in the efficiency of the system and shouldn’t require tune changes to be beneficial.

[@loudmouthgamer873]

@@DemonWorks gotcha thank you was just wondering cause I have been following all these turbo mods to make the engine noise louder and help with fuel economy and I want to do them just don’t want to run into the issue of having to tune cause in New York your not able to tune any diesels legally anymore

[@woods840]

@LoudMouthGamer thank a democrat.

[@gk9417]

I wish I was a mechanic 👍✌️🇨🇦

[@7171-Ws6]

Wonder how much louder it would be if you removed the foam ….

[@DemonWorks]

Unsure, I don’t plan on doing that though.

[@Vindobse]

Dude that's an astute observation I wanna take that shit out now do you think it'll make a noticeable difference

[@222grizzlyman]

Are you putting on the ppe transmission cooler on you new lzo to ?

[@DemonWorks]

Yes, I just haven't done it yet because I have staggered my installs. Next project is removing this charge air cooler so I can gather data. Next is the PPE engine oil pan followed by reinstall of the charge air cooler then the trans cooler right before I take a trip towing the car.

[@1g4u]

Delete kit out yet?

[@DemonWorks]

Call someone outside of the USA. Are you willing to kick down $5000ish for something like that?

[@LM2DeletedDirtymax]

​@@DemonWorksdefinitely not 5k it can be done for under 3k and tuning is trash right now definitely no need to rush into it tho

[@DemonWorks]

@@LM2DeletedDirtymax I disagree. Ecm and tcm unlock. Tune. Hard parts. Regardless, anyone can do anything “cheaper”

[@DaveE-b1c]

Great job on installation how did it drive

[@DemonWorks]

Will update soon ! I don’t have enough seat time yet.

[@DaveE-b1c]

No worries I’m excited to see your numbers and thanks for getting back to me much appreciated for sure your really good about that not many people do..🙏 I bet it’s gonna blow your mind how the motor responds to it

[@heazy87]

where in utah are you at?

[@DemonWorks]

Herriman

[@heazy87]

@DemonWorks oh ok sick, if I ever need some assistance or work done on my future 3.0 it cool if I hit you up? I'm in salt lake

[@heazy87]

@DemonWorks hey bud is there a way to contact you, I want to get a leveling kit installed and I'd be paying obviously.

[@ryanlogan2911]

Are you going to install the PPE rear diff cover and engine oil pan? I did the rear diff cover on my 21 AT4 and have been banging on PPE to build a cover for the front diff. I also hit up Fluidampr to build us a harmonic balancer.

[@DemonWorks]

Yes, the diff cover is going on real soon. Maybe the oil pan, will see !

[@a430vaudiguy]

Why did n't you just use a pressure bleeder?

[@DemonWorks]

It wasn’t needed. Pretty basic fill with no air.

[@williamcorleu5839]

I love a Duramax that's the truck

[@hahaadventures4838]

Looks nice but is the performance any better?

[@DemonWorks]

Unsure. Haha. Seriously just finished tonight. Will take a drive tomorrow and compare data.

[@DaveE-b1c]

Any different? More power?

[@nickchesko1719]

Update on my intercooler, it was a no go on my truck. My truck threw codes for 3 days and I averaged 12mpg. I installed it 2 to make sure it was on and with help of a certified mechanic still not working well and my truck ran bad. I ended up taking it off and my truck is running great again. Watch out this is definitely not a plug and play product and now I am trying to get a refund.

[@DemonWorks]

Sounds like you had an air leak. What were your codes?

[@nickchesko1719]

P026D and P0172, i checked everything out 3 times. Cleared the codes and it didn’t work.

[@DemonWorks]

@@nickchesko1719 codes are for fuel quantity too high and fuel trim rich. I’d say there was an air leak or restriction. I know the pipe in the back can be tough but who knows. Unfortunate you couldn’t get it right but it sounds like you are better now.

[@nickchesko1719]

Yea it’s just regular diesel fuel I always use and I just put the stock inner cooler back on and everything is working like normal no codes so I have no idea. Just wanted to give people a real world post install review and hopefully they have better luck than me

[@DemonWorks]

@@nickchesko1719 I don’t think installation error is something you had to warn everyone about, but to each their own.

[@ryanlogan2911]

Bump on suspense…

[@David-yy7lb]

Someone needs to make a kit to convert the stupid belt driven oil pump to chain driven

[@DemonWorks]

Did yours break?

[@David-yy7lb]

@@DemonWorks No, because that was the deal breaker when I did the research on the engine when gm introduced the motor and secondly gm claim 150k miles service intervals...no thank you I am not replacing a belt every year and a half or so. I do alot of driving so I'll just keep 08 6.6 GMC but I really think gm should have produced the baby 4.5 v8 dmax for 1/2 ton that they shelved in 07 or 08 that motor had the same output as the LB7 dmax and the 4.5 was gear driven valve train and crankshaft driven oil pump just like it's bigger brother the 6.6

[@markw-2025]

It really sucks that Duramax decided to shelve the LM2 for the LZ0, and especially frustrating that anyone who wanted a LZ0 diesel SUV is out of luck for 2023. So you have to purchase for 2023 a discontinued engine. Its not cool to keep changing after only a few year run. Parts will hard to get after awhile.

[@DemonWorks]

I hear your frustrations and I just want to point out that the LZ0 is based off the LM2 but with some improvements or changes. The LM2 was not shelved, it was just updated to the LZ0 for the trucks only. Most LM2 owners are very happy and many have commented that the changes seem minimal to them and they don’t plan on changing their vehicles from just this update. In 3 years, there will be another update to this engine, much like the 6.6 has received continual updates.

[@jrwstl02]

@@DemonWorksYes, mainly the LZ0 got steel pistons, slightly smaller bore (thus thicker sleeves), and slightly longer stroke (to maintain 3.0 displacement). Seems engineers want it to be more robust than the LM2, and agree there will be future updates. Our LM2 is a ‘23 Yukon and what a great combination! More power than our previous 5.3, very quiet, great fuel economy, way less gear hunting, and no DOD.

[@DemonWorks]

@@jrwstl02 Incorrect. The LZ0 received steel pistons, yes. Thicker sleeves, yes. The stroke and the bore is unchanged. I did a full video on this before the engine came out, believe I have done 2 or 3 because this misinformation is just crazy. The stroke did not change, what did change is the height of the piston and where the wristpin attaches to the piston is raised, so a longer connecting rod. The bore and the stroke remain the same. There are turbo changes, intake valve length changes, head gasket and. cylinder head changes. Coolant valve is different, the way the trans cooling system works is also different. kzbin.info/www/bejne/mqmznH5_jZJnl68

What’s the payload capacity of that truck?

[@Jakerthesnaker]

Roughly 1600 lbs.

[@LCNismo]

Are you going to install a oil catch can. I can’t believe that much oil with just 1500 miles

[@DemonWorks]

It is during break in and these engines come 1 quart over filled so I am not concerned about it, yet.
