doreHolden VZ replacement motor

[Richard Hitchings]

Hi all. Ihave to replace the engine in my VZ Commodore. I've been given different advice concering the 10 HBA numbers. Must the whole number match or is it only the first 4 digits after the 10 HBA? Any help would be appreciated.

Might be worth ringing Holden about that one. Not many blokes here have had engine swaps, and even less would have had your problem.

i dunno how much help i am mate but i am in the process of replacing the engine in my vz ute, its the 3.6 alloytech. all ive managed to find out is that if your replacing your engine you have to get the exact matching one as for some stupid reason they arent interchangable, for mine i spent ages tracking down a 10hbb, most i could was a 10hba or 10hbl, also if you look under the bonnet at the front passenger side of the engine bay there is a silve tag with diffeent serial numbers embedded in it, the bottom code is your engine type and you need to match that aswell, i think mine said leo on it

I was recently looking into changing my engine also, i was told from holden that the numbers have to match up otherwise it will have problems with the computer. Apparently they had to sort through 19 different engine codes. All i know for sure is i wouldnt be going out and buying the first alloytec i find. Talk to Holden
