VE V8 Aircon Belt being thrown off - Solution

[ZerOne]

Hi all.
Considering the number of members that have mentioned this issue in their modified VE V8's, you might be interested to know that a proper fix is now available from Holden.
It involves a replacement compressor mounting bracket incorporating an idler pulley (previously not fitted), with a longer belt to match. Most cars were previously fixed by replacing the commonly failing harmonic balancer, but a few cars proved stubborn, hence this release.

All VE V8's from 6G1EP4EH2AL419681 19/11/09 production on incorporate this fix.
For those whose cars are now out of warranty, or mod level leads to warranty rejection, these parts are now available for purchase at quite reasonable cost, and will take just over an hour to fit.

Part No.: Description
92252927 A/C Bracket Assembly (inc idler pulley)
92244381 A/C Belt

$100 buys both the above from your local Holden parts department.
