Why Do People HATE Cat ACERT Engines?

Josh, you need to be teaching somewhere. You are easy to understand and you have great communication skills

Normal engineering thoughts: nothing was ever made to eat it’s own shit🤷🏼‍♂️ EGR- Watch this 😏

I went to school for this and have been working in the industry for a few years and this was the best explanation of emissions systems I've seen.

Never saw this guy in my life. His video just came on and couldn’t stop watching him. You have to love people that know their shit and are able to explain the theory behind it. Nice!

I have a cat c 15 2007 acert mxs with 1444567 millon miles with no overhaul yet still running strong the acert system until 2007 make a little bit more complicated but no body can’t beat that boost,mine run 10 000 miles in every 21 days nonstop pulling flatbeds loads it’s just a beast with 3.55 rears and 13 eaton god bless caterpillar 🐛

I have a C15 Acert (NXS24662) It has been really good to me 1,4700,000. Going for it first inflame in a few weeks.

Thanks that was a lot information and I m glad I m out of the trucking business. If I ever had another truck it would be pre emissions and elogs. I’m so tired of government interference.

There is another way to solve this problem, politically, isolate the heavy truck engine line to its own LLC, make a very simple and reliable engine that doesn’t meet the EPA’s standards(what the customer wants), pay the fines, get government stimulus (your fine back) because the business isn’t viable do to the fines, and the line is an infrastructure necessity. To beat the government, beat them at their own game...

I drive a 2004 school bus with the C 7 210 hp engine, it’s a good enough for me in the school bus but a few years ago a drove a 3406 475 hp in a KW hauling fuel and it’s a big difference in the power . Keep up the good job of letting us know about cat engines .

I'll keep my old 3406b all mechanical. Never any problems, reliable, good fuel economy and pushing around 650 hp. And very easy to work on were I can do most of my own work.

Most guys nowadays rebuild them with 16:1 compression and delete the ivas. Keep the twins, good tune and you can have a good reliable engine with 700hp. As always thank you Josh for a very informative video! 👍👍

I’m a diehard CAT engine fan. I drove an 03 kenworth with a 550hp c-15 single turbo. Boy she’d scoot. Then I went to a 06 Detroit 14.7. It was alright. Then the biggest POS a maxxforce. I mean total junk. 2 egr coolers under warranty, a high pressure fuel pump under warranty and 4 egr valves under warranty. We live in the rust belt in Michigan and we were constantly changing coolant and oil pipes. Constant corrosion issues with lights. ABS lights on wet roads, way overly complicated hvac systems to keep us warm that we’re also constantly giving fits. Then four years ago I bought a Fitzgerald glider. Oh man talk about reducing maintenance cost! It’s got a 12.7 Detroit with 540k on it now. The only thing I had troubles with was the cylinder head leaking oil which was done twice because the front structure also was part of the problem. She’s the best truck I’ve owned so far and definitely believe I’ll get a million plus before the next overhaul. Still partial to CATS tho. Keep the vids coming. 👍

ACERT - Advanced Cash Excruciating Removal Technique.

The worst part for everyone with early IVAs was [I believe if memory serves] 'IVA #x not responding' were troubleshot by Cat by swapping IVA heads, putting it all back together, have the customer run it until a code returned, then see if the code followed the head or stuck on one cylinder. As a service manager at that time, I fought Cat tooth and nail because they refused to pay for two repairs with only one failure. After a while, iva heads just got replaced, -7 codes got new sokenoids, then those damned ARD heads came out. Constantly updating head designs, pissing off customers because Cat would not cover spark plugs even on a failed warranty ARD head. Ugh. I don't miss those days. That said, I was an International service manager during the Maxxforce days, so times got way, way worse.

Good explanation , l have 06 cat c15 and your right about injector harness . I just replaced both a couple of weeks ago broken wire . They had over 700,000 miles on them , engine light came on . I've had this truck for 11 years , had a platinum kit done 7 years ago . Its been pretty good to me , good power half decent fuel mileage . What l like most is the independent Cat dealer network , when l have engine issues l dont take it to a peterbilt dealer l take to a Cat shop . Everyone of those Cat shops over the last 25 years have been really good , they have a lot of knowledge and experience . They always fix the problem and get me on my way in a timely fashion . I have had other trucks in that 25 year period all had Cat engines in them . Only reason I have had this truck so long is it has a Caterpillar , and when it comes time for in frame l will not hesitate .

Much respect for the reasoning. Learn so much from you even tho I have a Detroit motor in my truck.

Of all the videos I watch on YouTube. I feel like I get more information and knowledge from your videos than any other. As a owner/operator of a c-15. I really appreciate you. Thank you for the information that you share.

Great video to understand all this engines complexity. I’m learning to deal with my Land Rover Discovery 2 with a Td5 engine now with 250,000 Km. Got rid of EGR system and having some blow-by. Initially thought it was not normal. Tried venting to atmosphere (draft hose-tube) but had to re-connect CCV hose to the depression valve in the inlet turbo hose. The problem was low turbo vaccum in depression valve at inlet turbo hose because it was cracked causing not enough vacuum to fully open the depression ccv valve to get rid of blow-by fumes. Better left all systems stock. Greetings from Guayaquil, Ecuador 🇪🇨

I run water injection on my 6nz c-15, which significantly reduces heat in the combustion chambers. This is a very good way to reduce or eliminate Nox. It also increases the torque of the engine by about 25 to 30%. I see a significant reduction in coolant temperature and also EGTs. I wouldn't run without it Too many advantages with no downside other than the cost and having to fill the water tanks. It will NOT damage the engine AT ALL if properly installed and operated correctly. Sno-performance has an excellent system. If you install this system I highly recommend you install at least a 30 gallon tank. I have 2 such tanks. These large engines can burn 60 to 80 gallons a day. I have been running it for over 10 years now, and have never had any problems with it or damage to my engines. This is the second engine I have run it on. NOTE; it's only effective on hills, and steep grades. It does not even activate on flat land.
