Hi all.

I am having some trouble trying to correctly sort out the vacuum hoses in my Hilux. Now, i have managed to source a diagram for it (attached), but I haven't been able to follow it very well. For example, according to the diagram, there are about 5 different vacuum lines that go into the side of the carby, but the diagram is not very descriptive of which one is which (refer to photo - attached). As for the rest of the system, it would appear that I am missing the "EGR" part of the setup, will this matter much?

I was wondering if anyone could post some photos of their vacuum system on their motor so that I can get a better idea of what goes where and sort this system out properly.

Thanks in advance for any help.

      Toyota Corolla 2012 zre152 transmission issue

      Hi Gary, I would suspect a clutch problem, like not fully disengaging. Maybe you aren't fully pushing it to the floor, or the system needs topping up or bleeding or both. Herb

      Toyota Corolla 2012 zre152 transmission issue

      Hi Toyota owners, I'm new to this forum registration. I need some advice or help as I have a shifting issue with my 2012 4 speed transmission. It doesn't do it all the time but the gears don't shift smoothly specially 3 to 4 gear it just bangs in when I'm cruising and it happens more often when hot. Got full transmission serviced with Toyota genuine parts no metal shavings in pan. Changed ATF 3 times. Full major service done, 100000 KLM on car. Full synthetic oil with 98 Ron fuel. Throttle body cleaned twice. Maf sensor cleaned. New spark plugs. No engine codes. Great loss of power sometimes specially on hot days. Please help as no mechanic knows what the issue is. Thanks in advance.

      Auto door locking on new 2024 C-HR?

      Yes mine is October 2023. It arrived late February Early March to the docks in Brisbane. I have a friend who has been told that hers will be in the next shipment but is only on the production line now. So future stock should be 2024 ! ?

      Auto door locking on new 2024 C-HR?

      Thanks Martin. I thought that may have been the case. However, it seems an anomaly with so much tech on board. My wife always looks for this feature after an ugly incident while stopped at a traffic light some years ago. As you said ...perhaps an OTA update? One other thing if you don't mind me asking. What is the build date on your vehicle? The C-HR's that appeared at my local dealer in the last fortnight all have an October or November 23 build date. Thanks, Peter

      Transmission U660e

      Not every Estima is fitted with the 2GR-FE and U660e drivetrain. This is where you have to take care that information on the internet is applicable to your specific vehicle.

      Auto door locking on new 2024 C-HR?

      Hi I was very lucky to receive one of the first new models last month. My Koba is amazing- as have all of my previous Toyotas. However in answer to your question it does not automatically lock the doors when you engage Drive or when you reach a preset speed. I am very disappointed that with all of the electronic devices and safety features and the approximately 20% increase in price over the last model that Toyota Australia has left a very important safety feature out of the vehicle. We see cars being carjacked almost nightly on the news. My knowledge of technology in this sector is limited but surely it is only an update of the operating systems to fix this. The new model is a beautiful car- your wife should still buy one.

      is it possible to import US model Sienna to Australia?

      I rent a 2023 model in US just few days ago it’s beauty and real good on fuel much nicer to drive compare to Honda Odyssey which I own one 2022 model make me wonder why Toyota AUS won’t bring the Sienna hybrid to Australia instead we get bulky ugly looking Granvia with diesel engine 🤔🤔!!
