Isuzu Dmax

If you are looking for a comprehensive guide on the Isuzu Dmax, this post is it. Here, we share all of the posts that we’ve written on the Isuzu Dmax over the years, from our build up post, what the vehicle weighs, what problems we’ve had, our 3 year review, things to look out for and much more. Please know a lot of these are translatable to the Isuzu MUX as well, as its essentially the same vehicle in many ways!

Isuzu Dmax

Our Isuzu Dmax, set up for touring Australia

Swapping from a Land Cruiser to an Isuzu Dmax

Changing 4WD'sThere was a long lead up to selling our 80 Series Land Cruiser, and purchasing our new Isuzu Dmax. It was analysed for weeks, comparing everything from reliability to capability, costs, weights, functionality and depreciation. This post covers why we moved in depth and how the two vehicles are polar opposites.


Our new Isuzu Dmax

Isuzu DmaxI’d never bought a new 4WD in my life, and seeing one arrive on my driveway was a pretty good feeling. This post covers what the vehicle is, why we purchased it, and how we went about it with a Novated Lease.

 


A new turbo for our new Dmax

4JJ1 motor in our DmaxWithin the first 20 minutes of me driving the new Dmax I had warning lights come on and could feel boost issues, which led to a new turbo being fitted. Ironically, this is a hugely common problem for the 2017 – 2021 Dmax’s too, but mine failed for a different reason.

 


Isuzu Dmax Build

AFN bar on our DmaxOur Dmax was bought for a specific purpose; to double as the family car around town, and to take my family touring Australia safely, comfortably and to get off the beaten track. Thus began our Dmax build where we fitted a myriad of accessories, removed the tub for an aluminium canopy, changed the suspension and did a heap of other work. This post gives you a full breakdown of every single thing done to the vehicle to get it to where it is today.


Isuzu Dmax Weight breakdown

Gravel in the DmaxThe weight of your 4WD is one of the most important factors for a huge number of reasons, and we were pretty careful when building the Dmax to keep it light and well balanced. In this post, we cover the weights of everything fitted to the Dmax

 

 


Isuzu Dmax and Reconn R2 mobile Weighing

Weighing the DmaxA couple of months ago, we loaded our Isuzu Dmax and Reconn R2 up to the absolute hilt for a 6 week trip away, and then had a mobile weighing company come and weigh everything, to see if we were compliant. I was certain we’d be overweight, but the results were actually really interesting. In this post, we break everything down, including axle weights and tow ball weight.


Isuzu Dmax in limp mode

Dmax towing a camperModern cars are full of electronic wizardry, and when we were just about ready to leave Karratha on a trip up north I had my Dmax get stuck in park with a range of warning lights come up in limp mode. As it turns out the issue wasn’t with the Dmax at all, but we learnt something that day!

 


Dmax fuel economy

Dmax travelWant to know the real life fuel economy of an Isuzu Dmax that’s decked out for touring, without the false marketing information, incorrectly calculated economy and people stretching the truth? Here’s our fuel economy when towing, and not towing.

 


Isuzu Dmax Problems

Dmax transfer caseNo vehicle is perfect, and the Isuzu Dmax has its fair share of problems. Some are common amongst a range of models, and many are not. We’ve had a number of issues, and documented them all here. There’s also a few things you should be aware of when buying a second hand Dmax or MUX, or even a new one.

 


Isuzu Dmax Review

Pender Bay in the DmaxAfter 4 years of owning our Isuzu Dmax, and more than 70,000km, we present our Isuzu Dmax review. This is non biased, covers the issues we’ve had, and what we really like about it. It’s not a fluffy marketing review, or one based on 5 minutes of driving the vehicle. It’s based on 4 years of literally living out of it for weeks at a time with my family.


Isuzu Dmax Build Cost

Dmax costsAlmost no one goes into the costs of buying, modifying and owning a 4WD. In this post, we cover every single cost spent on the Dmax, and a quick comment on each modification. The total cost is up there, although not nearly as much as a lot of people spend on more expensive vehicles.

 


Dmax catch can 

Provent Catch can after 5625kmWe initially started with a HPD catch can, and removed it in place of a Provent 200. The reasons are made very clear in the catch can comparison post we wrote, where we compared the two’s performance on our Dmax over a number of kilometres. If you are looking to fit a catch can do your Dmax or MUX, you’ll want to read this.


Dmax GVM Upgrade

OME GVM UpgradeWhen building the Dmax, my intention was never to get a GVM upgrade, but found the weights were adding up too fast and we really didn’t have a choice. This post covers what GVM upgrades there are for the Isuzu Dmax, and why we went down the brand route that we did.

 


Dmax Diff Drop

CV damage on an Isuzu DmaxAnother rather unexpected modification to the Dmax was a differential drop, to keep things lined up better and reduce the wear and tear plus chance of failure when out in the bush. I fitted the Diff Drop myself, which was pretty easy to do

 


Dmax transfer case leak

A leaking transfer caseOne of the most frustrating problems I had with our Isuzu Dmax was the transfer case leaking. We went through a number of seals, installed by a number of different people and eventually found what the issue was. It turned out to be partly modification related, and partly poor installation of the seals. If you are having a leaking transfer case output seal, this might sort you out.


Dmax diff leak

Not too long ago we had the front differential spew some oil out in Karijini, which was annoying. The leak stopped, and I suspect it was over filled in the separate part of the differential (that engages 4WD) but it still shouldn’t have happened


Fitting a transmission cooler to our Dmax

Davies Craig coolerI’ve been monitoring our automatic transmission temperatures for a long time, and after getting the Reconn R2 decided it was worth while getting a transmission cooler. The temperatures get too hot too fast without one, and the risk is simply not worth it. This post covers what we went for, and how it performs.

 


Dmax tyre size increase

Wheel trackIf you are looking to install bigger tyres on your Isuzu Dmax, you might want to have a read of this. We got away with legally installing slightly larger than 50mm bigger tyres, because of the differences between models.
