Good job Brother Just 1 thing I've noticed, the bracket holding the 2 heater hoses can be removed with a 1/4" drive ratchet and socket. Not easy, but not impossible !

@@phillipstock2652 Oh Excellent stuff! I couldn't get it the first time around so just cut the bracket haha. A lot of people do.

​@@AutomotiveActionMediaStubbie 12mm socket. Hardest part is getting the damn P clamp holes lined up and the bolt thread started! Character building exercise!

@@mjhmech4903 Oh nice, you got it! Haha. Some people have but i think most don't bother lol.

@@AutomotiveActionMedia hey mate, where is the PDF document for the clean? can't seem to find it. thanks for the video by the way, it'll be a good help

Thanks heaps! There will be more in the future, I just have to get through a few health issues first (no money for the cars). Thanks for subbing!

@@AutomotiveActionMedia have you had yours tuned/chipped?

@@moisty254 Not yet no. Definitely something I want to do in the future.

Haha, that is much appreciated Jimmy! Always happy to help

Thanks!! Glad you're going to give it a go. It's worth it!

Thank you 🙏

That awesome! I was fortunate as well that my swirl flaps had no issues. It does make a bit of a difference once its fully cleaned and swirl flaps removed. Thanks mate!

how'd you go with it mate? I am dreading it myself

No Problem!

Thanks mate! I have done this a few times now but the first time took about 6 hours.

Thanks heaps man!

No problem at all, you'll have fun!

Thanks mate! That's much appreciated! Honestly, there isn't a whole lot to look out for on these cars. Just check over the basics and go from there. If there is a bit of shudder when take off, it generally means 2 things, either rear diff angle is out due to lift, or there is hot spots on the flywheel. 2 very common things but both can be fixed. Check if there is a bit of dampness in the passenger footwell also. All that means is that the rear tail light seal above the rear window needs replacing. The water literally runs from the back of the cab all the way into the front passenger footwell. Jump on the rc Colorado Facebook page and hit the search bar, what to look for. There is plenty of people who have asked, including myself nearly 5 years ago

Thank you so much. The was in great condition just negotiating a price and the fact it’s a 4x2. I was after a 4x4. Cheers.

@@MrKeenaz No worries. No point getting something you don't want. I'd wait and find a 4x4 at the right price hey

Thanks mate! Yes I've heard of that also, and there is another hack where you can pull a fuse or relay out for the fuel pump and put two little wires into it and just let fuel run through the whole system without even turning the car on. I wish I could remember how to do it though haha

No primer on mine

My Collie doesn’t have a manual primer on the filter…

What do you lube it with?

Thanks mate, sorry I am unable to answer this one. I'm just not certain

Thanks! Nothing more to do other than clean the manifold :)

Hey mate, if you have Facebook, jump on the page and send me a message with some pictures if you can. Ill see if I can help out ✌

Thanks Jamie! All the cable does is trick the ecu into thinking that the air intake is at a particular degree so that the EGR doesn't open. I don't believe it is designed to trick the ECU into thinking it's at that degree for operating purposes. Purely for the EGR. As the old saying goes, with colder air, produces more power. So if there isn't any hot exhaust gases entering the intake and it's nice clear air, it means more power and reliability from your engine.

@@AutomotiveActionMedia awesome. Yeah it's a hotly contested topic, and I've heard of ZERO issues from the cables. Interestingly I know from reading the 4jj1 overhaul manual that the intake air temp sensor sends signal to ecu for egr operation yes, but also for the injection pulse width and timing. So it is used for AFRS.. And I hear ya, cold days mean dense air and more power, in a fixed fuelling schedule. But a PCM is going to see this trick cold air (even on a hot day) then adapt the fuelling to maintain a given power output. So on a hot day, it will underfuel? Potentially? Im also curious about the egr valve being used as a reverse flow dump valve for over boost conditions, can it still be achieved with Egr cable, or a tuned delete? Awesome vid man keen to see what you get up to next!

That's a good question. I believe it is closed for memory but unsure. Will look into it further. Thanks!

Revolution Projects ok please do

Revolution Projects Hi did you manage to find time to look in into it

That "Butterfly" is not a throttle plate, like in petrol motors. It does nothing during normal operation. Its function is to reduce the "shudder" diesel engines make when you shut them off. Nothing else. It closes only when you turn the engine off, then opens again via a spring. I hope this helps.

Everyone that has done the clean has said positive things about it. Petter response, fuel economy etc. If you were to compare a brand new Colorado with EGR and swirl flaps to one that does not have either, there may be some differences but I'm not an engineer and couldn't give an answer. I would assume the differences would be very minimal and not something people would actually notice when driving the vehicle. I noticed a slight improvement after doing the clean on mine and so did my mate. Definitely give it a go, will save your engine !

I can't quite remember if they even have seals but I didnt change mine at all.

Awesome!! Good on you for giving it a go. Should take anywhere between 5 to 7 hours depending on your experience, tools and how many beers you drink while doing it.

@@AutomotiveActionMedia cheers

Sorry mate, I only just seen this comment. By now I'm sure you have worked it out but I am also not as familiar with the newer 4jj1. Might be best to find a diagram on the net if it's a water cooling pipe. I'd have to see it for myself to provide any guidance.

Did you find a solution in the end?.

@@CRN8091 yip. Thanks

@@fowledbarrels8417 I got a 2014 DMAX and was gonna do my intake.how different was it from this video?.and how long to do the job?.cheers.

@@CRN8091 pretty much exactly the same accept for the coolant bracket. I had to remove the pipes from one side of the bracket that has the rigid pipe and tie them back to one side. Trying my best to not lose all the coolant. Tool me maybe 1.5hrs. Great video to follow

No

Yeah mate I had the blank plate in for the 35,000 KMs as well as the Munji EGR delete cable. And yes they are quite common to clog up. Should be pretty similar considering they are both 4jj1 but haven't had any experi nice with the later model engines yet. Good luck if you give it a go!

How did you get on with the DMAX manifold clean?.I want to have a crack but worried I might fuck something up 😂

That's right, just the munji EGR delete cable and the EGR plate. I have ran this combination for nearly a year and a half with no code thrown because the cable is fitted. 👌

Without using egr munji delete cable what will happen if i will use only egr delete plate?

Fritz von Paparon you’ll throw a code mate

Not a silly question at all. It is caused by a mixture of two things. Firstly, oil from the breather that travels pre-turbo through to the manifold. And secondly, the engines Exhaust Gas Re-circulation (EGR) System. Because exhaust gases are hot and entering the manifold to re-circulate, the heat 'bakes' the engine oil and clogs up the manifold over time. If you remove one or the other completely, you wont have the problem.

@@AutomotiveActionMedia many thanks.

Its up to you, but most people remove the swirl flaps completely by removing the two screws that hold each one in place. Others have found that the screws come loose overtime and eventually get sucked into the engine and they then are up for a rebuild. I removed mine completely.

Revolution Projects yeah ok then, so doesn’t affect anything by removing them?

@@runnin4adventure731 They do have a purpose, and they are called swirl flaps for a reason. They are designed to help created a 'swirl' which is meant to make the engine perform better. In my opinion only, I have not noticed even the slightest difference. Only better fuel economy and more power since removing all the junk.

Sorry for the late reply. You should be able to find a digital copy of the repair manual online. You may have to purchase it. Otherwise, the only other instructions I know of are on Facebook.

@@AutomotiveActionMedia no worries, thanks for the reply.Have you had a crack at valve adjustments yet?.

@@CRN8091 I haven't done much on the car lately for health priorities. Hopefully I can start making videos again soon 🤙

@@AutomotiveActionMedia sorry to hear that mate, all the best for a speedy recovery 🤙

@@CRN8091 much appreciated!!

Thanks mate! Yep, some people do have that issue. I'm unsure exactly why they do. I can only assume from bad fuel or maybe somehow from driving through salt water etc. Those that have corroded lines, have to purchase new from Isuzu.

@@AutomotiveActionMedia yes $1500 later and should be all good

@@logandietsch5699 I'd be questioning that.

No sir. I have the Munji EGR Delete cable, so no issues with that

@@AutomotiveActionMedia Thanks mate, I read that the cables can alter the AFR and make the engines run rich... have you heard about that?

@@bluedunn374 No I haven't actually. I know that it tells the ECU a 'lie' essentially and tricks it into thinking the something is at a particular temperature so that the EGR valve doesn't open. I havent run any official tests, but I've had the munji cable for nearly 5 years now. Has never cause me an issue personally.

@@AutomotiveActionMedia thanks mate

Usually up to 7 hours. I did mine the first time in just under 7 hours. But this video was 5 hours including controlling the camera

In just my opinion, I will never be fitting a catch can. They can unfortunately pressurise the system and cause other issues such as valve seals. These engine breath quiet heavily and so its not to restrict it. Plus, catch cans are lucky to collect 50% of the oil passing through. Its not worth it.

@@AutomotiveActionMedia Thanx for the prompt reply, would you recomend cleaning at say 100K intervals?

@@bildad1234 no worries. Judging by this test, easily every 100k

@@AutomotiveActionMedia Hey mate did you remove swirl flaps permanently or just for cleaning purposes?

@@bildad1234 We removed the swirl flaps and the screws completely. Leave the shaft in that run across the manifold

I cant say as I am not sure if they are exactly the same.

In this video? Or you're own car?

Hahaha, thanks for the offer, but i will have to decline :P

Hop onto the RC Colorado Facebook page, under the files section is the document

@@AutomotiveActionMedia just did and waiting to be accepted so i can download the file.

@@aaronroby4905 No worries, I'm not an administrator but it shouldn't take to long :)

If you can, contact me by sending me an email Automotiveactionmedia@outlook.com. Or message me on the Facebook page Automotive action media.

Just downloaded it last night very detailed but it says about the flaps in the manifold to remove them at own risk which is stumping me at the momment any ideas so do i remove them or not to the instuction guide as written ?

@@aaronroby4905 from what I know, the flaps are designed help produce a swirl when air travels through. Hence the name "swirl flaps". It does al restrict the flow a little at lower rpms as the flaps is not open as wide as full throttle. When you remove them, you remove the ability of swirling the air for better fuel consumption and a correct air fuel ratio. However, removing them, is such a minute difference, you will not feel it when driving or accelerating. You may see a slight increase in fuel consumption but I personally didn't.

Also when putting in the throttle body gasket does the gasket need gasket silcon on it or does the gasket go on dry ? I know the egr can have the gasket silicon on it just curious and thanks for the info.

@@aaronroby4905 the gasket is sufficient and nothing needs to be added 🤙

Hey brother. So sorry to hear the chemical clean didn't work out for you. Im not much of a beer drinking but can help out where I can mate.

@@AutomotiveActionMedia This video was real helpful today mate, I finished it all within 4-5 hours 👍

Thanks! My car has been well looked after. It was as easy the first time as it was the second time. Only differences being 1. The manifold itself was clean the second time and 2. I didn't have to cut and remove the bracket on the back of the manifold. :)
