Hello everyone, just wondering if anyone has heard of any problems with the 2012-2013 Izuzu Dmax clutch or timing belt. I have heard of other makes with chain and dual clutch having problems. Thanks in advance John.

G'day John and Maureen
The 12/23 engine and manual transmission is the same as the 2011. Engine slightly more powerful.
It has a cam chain and is a very well proven engine, these being also in Isuzu trucks.
No issues as far as I know with Dmax cams chains, unlike Navaras.

The clutch isn't dual but the flywheel is a dual mass unit like most these days.
Most, not all, Dmax appear OK but many other makes often report failures of the dual mass section. They become noisey and rattle.
The clutch of a Dmax is 25mm bigger in diameter than a Hilux, older BT50 and Navaras.
Theoretically this should allow more torque transfer ability without slipping.

All can give trouble if used for heavy towing and uphill takeoffs.

Thanks for the reply Ross and Bruce. I have just sold a reliable 97 HiLux 348ks and purchased a new DMAX manual and got a bit panicked hearing about other failings, as we will be towing a 2ton GVM van.

Hi John & Maureen, I've never heard of any timing chain issues with the DMax (or the Navara!) It's engines with timing belts that seem to have the majority of issues.

The issue they do have is that dual mass fly wheel! Dual mass fly wheels are installed by manufacturers as they reduce noisy rattles & vibration, thus increase passenger comfort (in theory lol!) BUT they get very hot as a consequence of the way they work. Heat + clutch plates = premature failure!

Heat + Clutch plates + towing a 2,000kg van off the line = ?

I don't think its a huge deal, its just something to be aware of! If you like the DMax, just run it till the clutch gives you trouble & then install a conventional fly wheel when you install the new clutch.

Cheers,

Kevin.

16Ks on our new D.Max and not one problem, ours is an auto. I would not buy a manual after having these auto. Off to Darwin and the Kimberley in two weeks, will let you know how it goes.

John...... what you hear and what is the truth are usually miles apart, according to the world wide web nearly everything ever made has major failures.

Clutches are a problem in most late model 4x4 utes but I would say not every one has a problem..... as for timing chains, there's always the the odd one.

Dual mass flywheels have more problems then standard flywheels but again few and far between.

Seeing your asking about 2012-13 model Dmax..... maybe in the future more problems may appear but they are probably to new at this present time.

Remember the world wide web is a fantastic breeding ground for over emphasising non common problems.

Hi john, the D-max has a stainless steel timing chain, no problems there and our van weighs 2.6t / 2.7t in holiday mode and so far max has handled it ok. Brother inlaw has a 2012 d-max and all it does is tow vans for a living no problems.
cheers Warren
