    3.8 V6 Using coolant - LIM gaskets recently replaced

    The LIM gaskets were replaced about 3-4 weeks ago by a garage who did another job on the car. Since then the car has started using water. About 400 ml per 100 km. There are no signs of a leak anywhere. I suspect the problem might be the LIM gaskets even though there is no evidence of water...

    Oil dripping from bottom of bellhousing

    Background. 2003 VY 3.8 V6 manual Gearbox has just been out for overhaul. Previously had a water leak with water dripping from bellhousing. I concluded it was the rear blanking cover leaking. For the time being I had reduced/pretty well stopped the leak by backing the radiator cap off to the...

    Blind Side Alert Lamp not working on passenger mirror

    The Blind Side Alert warning symbol on my passenger door mirror isn't working as it used to. As far as I can tell the sensors are working OK as they are also used are used to detect nearby objects when parking and I get warnings from nearby objects on the DIC and audible alerts when parking the...

    Noisy manual gearbox on VY 3.8 V6

    I've had this noise for a while now. I originally thought it was engine related as it sounded a bit like an exhaust manifold leak. It was only noticeable under acceleration. Trouble was I could never hear anything when I had a listen with the bonnet up. The gearbox has always been a bit growly...

    Park Brake Issue

    I have problem where the park brake on my right rear wheel isn't working as well as the one on the left side. I've checked and set the adjustment. With both wheels jacked up both wheels, when turned by hand, lock at the same number of clicks when you pull the park brake handle. Yet if you apply...

    Leaking rear diff

    Has anyone else had a leaking rear diff. There's been quite a bit of discussion about this issue on the Buick forum. Had my car in for a service the other day and was told the diff was leaking,..... again. At the previous service they noticed a leak. They fixed the breather which was apparently...

    Is there a way to disable the alarm but still lock the car?

    We're crossing the Cook Strait on the ferry. They have a requirement that the alarm be disabled. Is there anyway to lock the car without the alarm being armed? I'm guessing they're probably concerned about motion alarms as they also talk about disabling any towing alarms. Which leads me to...

    Punctures

    I'm curious what experience other owners have had with the OEM Continental Conti Sport tyres with respect to punctures. In just over 30,000 km I've had 2 slow leak punctures. Perhaps it's just bad luck but I've never ever had this many punctures with other cars or brands of tyres.

    Second cracked front screen in six months

    Six months ago I had to replace the front screen due a crack from a stone. From the sound the stone made when it hit the screen it sounded like a small stone. The same thing happened the other day. It wasn't a loud noise but the screen has a crack that is too large to be repaired. Two...

    Unsettling handling when overtaking

    I've noticed what I'd call unusual handling when I've made some overtaking manoeuvres. It's always been when I've used heavy acceleration. When I'm about halfway through the manoeuvre and have built up sufficient speed and ease off on the acceleration the backend seems move or squirrel around...

    Fuel Consumption Figures

    To get a comparison between my old VY 3.8 S and my ZB 3.6 RSV I've been tracking the the fuel consumption of both vehicles. The consumption figures shown on the car display for the ZB are consistently 0.4 to 0.5 L/100 km less than the calculated figures using the actual fuel bought. The VY is...

    Auto volume function on sound system

    No matter what setting I choose the auto volume function doesn't seem to work. I have this function in my VY S and the volume increases as the speed (and ambient noise) increases but I cannot notice it working on the ZB. Has anyone else have noticed this too?

    I had the windscreen replaced the other day, now the rain sense function no longer works. Genuine screen fitted. I'm taking it back on Monday for the repairer to sort out. In the meantime I'm curious to see if anyone else had this problem?

    Towbar harness question

    I had a towbar fitted today on my RSV liftback. The harness listed on the invoice was for non AWD yet the RSV is AWD. My question is why would there be a difference in the harness between the 2WD and AWD? If there are different harnesses why fit the non AWD to a AWD vehicle?

    Fitting mudflaps to an RSV Liftback

    Has anyone fitted mudflaps to an RSV liftback? The genuine front ones don't fit out of the box due to the body mouldings between doors. I think they could be trimmed to fit, just wondering if anyone has done it?

    I need to remove the plastic mounting for the PCM on my 3.8 VY S. That's the black plastic mounting which sits behind the kick panel on the left side of the passengers foot well. I was refitting the dash pad after replacing the heater core when I dropped the screwdriver bit behind the kick...

    Which HVAC evaporator?

    I went to order a new evaporator core for my manual 2003 VY 3.8 S (Series I). From memory built April 2003. I was told there are two different evaporator cores and the change over occurred about the time my car was built. The difference between the two cores apparently is where the pipes come...

    Hi Guys, I'm in the middle of removing the instrument pad assembly to get at the HVAC to replace the heater core. All the info I've been able to find on here about removing the instrument pad assembly relates to the VT or VX. I had expected to be able to remove the instrument pad assembly...

    Sunshades

    I'm looking for a windscreen shade to fit my ZB. Most of the shades you can buy don't have a big enough cut out for the rear view mirror/rain detection unit. The Holden one doesn't appear to be available in NZ and even then it is a an eye watering $120AUD. What/where has anyone found that fits...

    18" or 20" rims on an RS-V?

    Has anyone on here any experience with 20" rims on an RS-V? What's the ride like? Are they worth the extra money you will spend on replacing the tyres?

    Coolant dripping from bellhousing

    I have a 2003 3.8 VY S manual. It's done about 380,000 km. It's just started dripping small amount of coolant when it's parked. Truth be known it's doing it while I'm driving as well. The drips are coming off the bottom of the bellhousing. I cannot see any wet areas above that, but it's hard to...

    Non availability of VZ parts?????????
