air con belt gone

[blown vess]

Hi guys had the same problem over and over a/c belt comes off I think I was talking to dave sat night and he I think he said someone has found a cure please let me know

I have been told that this is a common VE problem - and not just the V8's....

My old SV6 company car chucked the belt 2 days after picking it up and Holden changed the A/c pump and all was well after that.

I have heard that some of the VE's have a wrong size pully on the AC and thats why it keeps chucking it off....but not entirely sure about that.

ask Pete (Calaisrider).
He used to spit drive belts all the time & problem was eventually solved.
Might be a similar fix ?

seems this is a common problem with the VE's, untie's VE turned out to be a wrong size aircon pully ( like 2 - 3 mm difference :confused: )

Agghh welcome to the VE Flaw.

On my first L98 in the current car I had a period there were I was throwing air con belts and ocasionally snapping the drive belt from the force of the A/C slipping off almost every second day up to fortnightly. Cost me a literal fotune in belts lost, broken or shredded, and was dangerous when the main belt got blown off - no power steer nor engine cooling. Burned hands became the norm refitting the belts on hot engine. I even bought and installed a new tensioner but to no avail.

Seems to occur as you add power mods and HP. IMO the tensioner is just not strong enough to contain the massive pressure variances when on and off throttle quickly without the additional pulley that was part of the previous LS1 line.

The best fix I know of is that of "Delco" (LS1 Forum). It simply places another pulley in the loop and stops the slap/slack of the belt when on and off the throttle. Hell the required holes and threads are already built into the block as stock. In the scheme of things its as cheap as chips to buy.

Not one problem since fitting it. When I blew the begeesus out of the first engine, I then changed the Delco mechanism over to the new crate engine as a matter of course and all is still good.

Yeh I do run a 25% UD (the first engine had more mods than the current one). AS A BONUS - adding the Delco pulley resurects the total belt length back to that of the stock dimensions, and as such, you don't have to look for special size belts appropriate for the 25% UD reduction in belt length.


I used to carry 3 x spare A/C belts and 2 x Drive belts as spares all the time as I expected to use em (oh, and a set of long length leather welders gloves to reduce the mandatory burns on the arms). Nowdays I don't carry any spare belts at all.


I thought that Holden acknowledged this fault and fixed it as a patch / warranty process???? Last I knew it was said to be an alignment issue out of the factory.

Yeah, sounds like that is the go. I have had a few go. One i just happened to notice (was showing the engine to someone and noticed the belt had started to wrap around the others... not good.. I still have to get it fixed and i'm not sure if who pete mentioned was the same crowd i heard of but apparently a Co. in WA has a similar thing.. I really need to get back to James at BEST and ask a few more q's as he was the one who told me about it..

The problem is within the Harmonic Balancer. There is a re-work on them for cars still within warranty.
