Hi All. I've put all new (six) - Genuine GM / AC Delco shift solenoids, 3-2 downshift solenoid, and Force solenoid etc on my VZ LS1. I've got a Tech 2 and wondering is any sort of parameter reset required in terms of ECU re-learning etc if required. Thanks

Hi All. The steering on my VZ V8 appears to be lacking at low revs, time has come to put a new pump in. I see there is a decent price difference between a GM Steering pump and a AC Delco one. Even though GM owns AC Delco, they appear to be not exactly the same pump. Has anybody used both and...

Thanks for the replies guys. I guess I left the 5.7 out because it appears to be quite slow until it wakes up so more of a motor you have to rev to have fun with. Would a 6.0L Auto pull harder right off the line as you stab the throttle?

Hi Guys. I have a VT Wagon 3.8 and just for some fun I'm chasing some more punch right off the line without changing diff gears, I'd like to put a larger engine in it. I have noticed the Ecotecs just have amazing take off and torque below 3000rpm even against some V8's. The car will remain...

What's the difference between the front suspension on the VZ compared to the VY, commodore665 you mentioned its more compliant? Is it bushes, or struts? I do know sometimes some cars are fitted with aftermarket struts that always are more harsh than the originals that are so nice to drive on...

Hi Guys. I use a VT as my work wagon and I need to carry conduits in there, lengths of 4m. I'm wondering can you attach a conduit carrier to the factory points without it sagging or cracking. Has anybody done this and how have you gone about it, I can't have it hang out the back too...

What is the go with the timing chain tensioners failing. Some have said the chain stretches itself causing failure, but I cant see how a stretched chain puts more load, it should put less load on the tensioner as it has more slack. I know this is apparently a costly fix but I want to know what...

Thanks for the input mate you are of a great help. I would like to hear from anybody else with their VZ ownership, thanks guys. Has anybody had sensors or modules go, things that will just bang leave you on the road this is what I'm trying to replace as it was common in Ecotec. I'd like to hear...

Thanks for your reply mate, it helps put things into perspective. I guess without being a Holden Dealer Mechanic who see's these things day in day out it's hard for me to know. I'd appreciate any other guys inputs especially the good and bad also, trying to find more info on the timing chain...

Hi Guys. Looking to get a VZ Commodore, from having my VS I remember all sorts of things were failing on it which would leave me stuck on the road. Crank angle sensors, DFI Modules constantly dying, failed coilpacks you name it. I'm going to get something low KM, about 100,000km. I want to...

Hi Guys. The time has come to probably buy a VY or VZ Wagon. I'm wondering does the VZ have any changes other than the VY other than the motor, but mainly interested on peoples experiences who have owned both. I have heard the VZ V6 is unreliable compared to the Ecotec. It will be a work...

Hi Guys. OK here is the situation. So I had a bootlid painted, they blended into the quarters so I believe they painted the top part of the 1/4's then cleared it. It's a metallic silver colour. All looked good but then one day I noticed what looked like few dried rain spots on there...

You have a leak, how to fix it depends how bad the leak is and where it is. Step 1 - Can of Degreaser and lots of rags, clean, then clean again until it is dry and not oily at all, this does not mean a she'll do mate type of Job, really get into it, everywhere from bottle feed hose, bottle...

Trans fluid Levels are fine not leaking at all, this happened almost like day and night. Trans code was 66 which is a downshift solenoid, but the taking off in 4th Issue seems to say to me that one of the Shift A or Shift B Solenoids would not be working?

Hi Guys. I have an issue where my VS takes off real slowly, it feels as if you are driving with the brakes on, at the same time this started to happen, it began to engage real harshly from Park to Drive. Is this generally a problem with one of the shift solenoids or is there other common...

I'd say the next step is to change the crank angle sensor, common problem, then either faulty ECU, or a Security issue.

The car cranks perfectly, but many times it will start up the first go then turn off almost immediately, then the electric fan turns on. I am pretty sure are this stage it will not let me even crank while the electric fan is on (have not verified)..... I have to turn the key all the way to off...

Could also be bad BCM or ECU? I thought that security is disarmed once you hit Unlock on the Key? So would it be fine to assume if the locks unlock, that the BCM has signalled the ECU to disarm itself and be able to fire injectors and ignition ?

Hi Guys. I'm wondering what's the cause of this issue. My last VT did it and my currently VT does it. The car would not start and then the electric fan comes on. I have to turn the ignition right off, then turn it back on and then the car will start. Thanks.

Normally which part is the one that is the biggest contributor, is it the Diff or can it be anything?

EDIT - I have just Fixed it, The issue was the ground wire did not have a good contact on the bulb holder, so when both the stop and headlight have to operate at same time, the ground wire cannot flow enough current to the battery to support power to both bulbs. Hi Guys, I am having this...

Hi Guys. Just wondering if anybody has had this personally happen. Just had car with a pretty new replacement DFI module that failed. I'm starting to think could perhaps a coil somehow short the module out, and have you guys ever had this happen or how common is it? Cheers.

Hi. I've got a VT and have been getting very bad economy, there is no error codes. The car chews up petrol like crazy even for just light highway driving. The Engine is in very good condition, starts in one crank and has very good compression, no smoke or anything like that. O2 Sensors...

Hi Guys. I got a VT V6 and seems to drive a bit differently to other Ecotecs, after reading a few common faults on the Phoenix Mechanical website it was mentioned that it can seem sluggish as it normally doesn't shift down unless lots of throttle is applied and also stating some cold start...

Where's his cash? :P haha I know how it's like can be like a Jigsaw puzzle sometimes I always now Label things and take pictures as it always ends up biting me back

Hi Guys. I've had no problems with Aftermarket Caps on Commodores Before, I always use CPC. I guess there are dodgy ones out there it's hard to find a good fit sometimes, That will be the next step if it's still losing coolant. So i thought I'd start with a pressure test, Repco wanted $150...

Cheers for the Replies got me thinking lots of different causes. I cleaned out the Overflow. The coolant in the radiator looks a bit to the brown side allthough no oil sludge in it. unsure if it is just gunk accumulation over time or not. About the rad cap pressure seal, if it were faulty and...

Hi Guys. Just got a VT V6. Overflow bottle is filled with milky residue. Radiator Coolant is clean though and Engine oil is perfect. Car does not smoke, starts fine and drives great. Every few drives or so the radiator gets a little bit low on water, e.g not to the top but a little...

Hi Guys. The Idler pulley closest to the a/c compressor is not coming off, seems siezed so i cant pull it out, tried a puller but it seems it needs a huge amount of force how siezed on it is. I may end up breaking it, so my question is, the bracket that the pulley bolts onto, is that...

Hi Guys, I've decided to do a V8 Conversion on my VS S2 Wagon Auto. It will be a 5.0L and Also an Auto behind it. I need to ask a few things : 1. I take it you need a V8 K-Frame and Rubber Mounts? Cannot use V6 Crossmember? 2. Will Original Fuel lines, Power steering line from...

Hi Guys, Although it's not relating to any commodore in specific I thought I'd ask here. I got a car that I need to put electric fans in, But I want a Shroud that covers the whole radiator, not about 2/3 of it. Roughly the Shroud size is the same as EF/EL Falcon fans, but those fans hit...
