Type that code into your google bar and results will give you all you need to know about the code. Most likely it's a manufacturer only code and has to be researched on line.

Hi David being a VZ it will have timing chains, I don't believe there is a set time for replacement. It is very important to have regular oil changes using the correct engine oil. If you have known the car for many years and had regular oil changes then all should be good. If you don't know the service history my advice is book it into Holden's or have a very knowledgeable mechanic remove rocker covers inspect inside for any sludging and any advice he would give on the internal condition from what he has seen. What happens under normal wear conditions the timing chain stretches this inturn puts on the engine light going from memory it sets an engine code : 007 or 008 this is when timing chains require changing. The reason for checking inside the covers for sludging is: if there are signs of heavy sludging this will shorten the life of the engine and chains, and without any notice ie engine light coming on the chains could give way before engine light comes on. If this happens it would be to late as any damage would have take place. I hope this information helps. Good luck

Hello Steve Templer,

I'd need the year & engine size to get MORE SPECIFIC
(but still quite answerable/easy).)

The quickest and best way to "show" it is to get the new thermostat, gasket & sealer from your dealer...

Go to the engine side of the top radiator hose.. pull those bolts...

Turn the housing over and look at it...

check with your service dealer as most commodores were constructed to carry either engine as the v8 was an upmarket version of the cheaper car
there are plenty of holden car clubs that will be glad to help you with the solution

The first thing to do is have the codes read as the codes indicate where the fault is
Supa-cheap shops now offer a scanner service and although it costs a few dollars ,you will be armed with information that will either be the same as what the service dealer is saying or you will be able to get a second opinion from another service dealer.

check a shop manual _ can purchase at Canadian Tire

You may have a plugged AC water condensation drain hole, it drains under the car at the base of the engine bulkhead on the passenger's side.
