Hi all,

What is the advantage of having a lightweight crank pulley (same as original size) in our 1ZZ's?? are they any downside to this? I saw some for the U.S 1Zz's will they fit ours?

There's no real advantages when you consider the disadvantages of the poverty-pack non-dampened crank pulleys. Faster bearing wear, transmitting ALL the vibration from your ancillaries to the crank main bearings, etc etc. Riceboys will say they're a great thing though...

Tons of info on why the cheap alloy crank pullies are a bad idea, if you want a "light" crank pulley, get Ross Balancers or similar to design one matched to your engine harmonics.

      Towbars

      I went to my local Toyota Dealer for a nudge bar and tow bar for my 2017 AWD RAV4 and was told by their part's department was told "parts no longer made." Looking at aftermarket (ECB, Haymen Reese and ARB) but hesitant because sellers can't give 100% guarantee that parts will fit GLX facelift model.

      Concerns about Fuel Consumption in Kluger Hybrid

      I have the same issue with my 22 new Hybird Kluger. I also found my (grande) new Kluger has missed 220V power point and camera view on central mirror comparing with same car in US. This clearly are the short cuts to Australia Toyota customers which is unacceptable.

      ASV50 Camry Head Unit Options

      I have a 2014 Atara SL with the JBL Navigation head unit, it's getting a bit long in the tooth and I'd like to add Android Auto so I'm curious about what other owners have done. I don't want to lose the reverse camera and the dynamic guidelines, there are also some other car functions as part of it that would be good to keep. I have seen plug in modules that wire in that add the functionality to the existing unit so it's possible to keep it and switch between stock and android but I haven't seen a specific one for this model JBL unit. Has anyone had success with a later model Toyota unit bolting in?

      1zz-fe engine rebuild

      Hello all, Working on my 2002 corolla. It needs a engine rebuild due to burning oil out the back. It has over 400,000 km on it and I havent looked after it. Everything is still original on the motor. The only thing that I have replaced, was the brushes on the alternator. They were completely worn out. I am pulling the motor/gearbox out of the car. Wont know the condition of the block or head until I strip it down. I know the design of the piston where changed in the 2003+ models for more oil holes, which stopped the buring of oil. 1. Was there any other changes made ? 2. Does anyone know of where I can get a engine rebuild kit for 1zz-fe motor in australia ? 3. I have only found one place that I can get a new short motor built but that is in the USA and they do ship to australia but was hoping to find something in australia Thanks for help. Dragon

      2007 Corolla Sedan rear seatbelt question

      Hi everyone, new member here. I've got a small problem which I'm hoping you can help me sort out. I've read the "read me first" thread and done a forum search so apologies if this ends up being a repost. Ok, so I've just has a bloody mouse chew through the rear seat and half (but only half) of every rear seatbelt. Which is nice. So I need to replace them. The problem I appear to have is that none of the local breakers have any suitable vehicles that I can pull them from and the ones I ordered and was sent from the bay of fleas has the wrong brackets on, despite being allegedly for that vehicle. Further searches come up with every seller showing the wrong bracket, so either I've got a special car which is different just because, or (more likely) they don't know their ****s from their elbows what they're selling. I'm after some aftermarket ones as they never get used and just need to be there to get through rego so don't really want to spend a heap of cash I don't have on genuine parts if I can avoid it. I've replaced the centre one (a mate just randomly had it in a box in his shed, which was handy) but still need the left and right. I've attached the bracket type I pulled from the car and need. Is this a standard generic Toyota seatbelt or specific to the 2007 Corolla sedan? Does is need to be specifically for the rear left and right or do front ones fit? Does anyone know where I can source an aftermarket pair? I will really, really appreciate any help offered with this, I know my way around a box of tools but very little about mechanikicing (which is part of the reason why I bought this car - something simple to learn on as repairs/replacements become due) and this is a simple fix which is turning into a drawn out headache. Thanks - Matt

      Hi from Wagga

      Hi folks, I'm in Wagga, have what I thought was a nice, cheap and reliable 2007 Corolla, and am joining in the hope of picking the collective brain to troubleshoot and avoid tossing my computer and the relevant car parts out of the nearest window. I'll play nice and restrict the swearing to off line areas :D See you on the threads! Cheers Matt
