ISUZIE I-MAX OR HILUX OR COLLERADO

Why do people maintain the inacuracy of stating "they are both Isuzu's"
This is simply not factual.

Both vehicles are built at GM's Rayong Plant in Thailand.
The Isuzu D-Max therefore is a rebadged GM vehicle, made under a contract agreement with General Motors Corporation.


Bill.

Bill,

They may well be built in a GM factory in Thailand but they are designed by GM subsiduary ISUZU.

Likewise, the Captiva, Barina and Cruze are all GM, if you insist but, they are all designed and, in this case, built by another GM subsiduary, Daewoo in Korea.

Look at it the other way...the Commodore is sold in various overseas markets and rebadged Chevrolet, Pontiac and even Vauxhall.

So, are THEY just GM vehicles built in a GM factory in Australia...??? Strictly speaking, yes they are but there wouldn't be any Aussie who would allow that to be thought of as true, but it is a true as the statement you made...am I making sense here??

Bill I am afraid you need to do a little more research, GM has no affiliation with Isuzu being wholly owned now by Mitsubishi Corporation (not Mitsubishi Motors). The Colorado and the D-Max are built in different factories, and there are not quite the same, the Colorado has a SOHC motor and the D-Max has a DOHC motor, there is a couple of other differences as well I won't go into that now. Good article here

Wrong again - both colorado and d-max share the same 4JJ1 motor - the SOHC theory was debunked ages ago.

Hope this helps.

I got my info from www.redbook.com.au and have been told by many other sources that is correct.

I was wrong about Isuzu being a subsiduary of GM, it's not and never was but, there have been agreements over the years for Isuzu to build GM vehicles for other markets. The Holden Jackaroo springs to mind. I had the Isuzu Trooper when I was an expat in Malaysia and it was EXACTLY the same as the Jackaroo and in this case, despite all the chest beating, the D-Max and Colorado are one in the same vehicle, designed by Isuzu including the engines, I don't care who builds them or where. The only differences are slight trim detail and the badge.

I got my info from under my bonnet.

My engine Number is 4JJ1FW1050

Feel free to do your own homework using my engine number.

Also, just checked the Australian websites for both Holden and Isuzu.

The Colorado has both 3.0l CRD diesel and 3.6l V6. The D-Max is only sold in Oz as a diesel and both outputs are exactly the same, that is, 120kw and 333Nm from 1600-3400rpm in auto form. Torque is slightly higher in manual at 360Nm from 1800-3400rpm.

The petrol engine is no doubt the Holden built GM global unit as in the Commodore, although not certain about that.

I've heard holden is going to discontinue the v6 - don't know if it's true or not...

sic em Bruce ....

I'm with you. I followed up on all this stuff before I bought my D-MAX. Here is my VIN Plate ...

Who cares? All a reliable vehicle has to do is get you from point A to point B. Something my Patrol ZD30 could never do !!

Malcolm

I am just waiting to get under a Colorado bonnet hehehehehe probably have to take the cover off only problem lol

Malcolm, It's your engine # that he needs to compare - the one that starts with 4JJ1

Bruce - I checked with your redbook line too - they have it listed as DOHC anyway.

When will this end?

Engine # GR3712

It looks like the motor is not the same - Holden don't give enough info - But I wouls say different motor :-) Cheers

gbc did you actually take the cover off the motor to see if there was two cams there or is it just the engine no? I went back to www.redbook.com.au and for the Colorado/Engine...Cam/Overhead Cam....Valves per Cylinder 2
the D-Max/Engine...Cam/Double Overhead Cam...Valves per Cylinder 4
Yes they both use the same 4JJITC engine classification no, also I have found the D-Max is a lot quieter than the Colorado that's why I did the research.

Seen with my own two eyes - she's a gear and chain driven DOHC 16 valve engine.

The only isuzu motor with SOHC was belt driven and not common rail.

I was under the same impression as you guys until I did a LOT of digging to get to the bottom of it all.

It is exactly the same engine as was in the ra7 rodeo which was a full blood isuzu d-max from before the confusion set in.

It would appear that there was a typo made (2 valve typo) a long time ago by holden in some advertising guff, and the isuzu sales guys flogged it for all it was worth - why not?

Have a good one.

Many of the parts are interchangeable and come from the same supplier. Likewise, Falcon, Toyota and Holden share some parts too.

In regards to the Toyota Hilux myth...I agree. Most utes are a much for muchness these days. It boils down to what's better suited to the individual. For instance, the Hilux has it's eye level brake light mounted on the tailgate which may not suit people who often carry over length loads that require the load to be transported with the tailgate down....just one example of many.

Bed height for a hilux is higher too, which makes for back breaking work if you're a traddie.
