Hey guys i had an idler pulley replaced on my VY under warrany some months ago and ever since my fuel consumption jumped an average of 2-3 liters per 100 kms no matter how i drove the car.
I finally took my car back to holden and got the pulley replaced again being as it had become noisy and all of a sudden my fuel consumption has dropped back to what it was when i 1st bought the car back in march.
I am now averaging arround 11L/100km with an average speed of 48+kmh where is would normally be getting anything from 13.2 to 14.5L/100km .
So for all you out there with a thursty VY V6 check your pulleys as you may find them to be shot.
Shot pulleys load up the engine like an A/C compressor. Thats what (I believe) causes high fuel consumption.
Far out.......i'm lookin into this one...thanks 4 th tip.
The thing that really anoys me was that the Holden dealership installed a faulty pulley under warranty and would not change it when i complained about higher fuel consumption when the car was still under warranty so i have drivven arround for the last 6 months and 12000+kms with my car using alot more fuel than it should have been.
yeah im gona look into this as well thanks mate
anyone know how much they charge to replace both idler pulleys and belt. labor + parts?
I cost me arround NZ $150 to get mine changed
I am in the process of trying to get my VY to the dealership (under warranty)as it is making a noise from what appears to be one of the pullys!
I am currently getting about 10l per 100km and 7-8l on a trip.
