waderz06 Posted May 16, 2008 Share Posted May 16, 2008 Non TT? So its an N/A? If so then the throttle body has to come off. Its not hard though only need a 12mm spanner or socket and maybe a 10mm. Good Luck mate Quote Link to comment Share on other sites More sharing options...

creative Posted May 16, 2008 Share Posted May 16, 2008 its a non tt so an N/A yeah.. dead easy to take off. 4 bolts I think it is as said before! Quote Link to comment Share on other sites More sharing options...

Rob Posted May 16, 2008 Share Posted May 16, 2008 so an N/A yeah.. dead easy to take off. 4 bolts I think it is as said before! 4 bolts for the support bracket, then another 4 for the actual throttle body but you will have to renew the gasket between the TB and the Y-shaped tubes, which you'll have to order in from Toyota in advance. Don't forget removing the air filter pipes, the TPS plug, the IAC valve plug (careful you don't break the plastic) and various hoses and vac hoses To avoid having to buy a new gasket I'd advise keeping the TB and the Y-pipe together and unbolting the pair from the intake plenum, which is 6 bolts, 4 vac hoses (inc a little one underneath the Y-pipe to watch out for) and the cam cover breather pipes. This exposes a multi layer metal gasket which doesn't need replacing. Get some carb cleaner and clean out the TB and Y-pipe while it's off to remove the black scum from inside.

Rob Posted May 16, 2008 Share Posted May 16, 2008 and the throttle cable, you'll need 2 12mm spanners for that, and a deep 12mm socket for most of the bolts plus a uni-joint for the front lower 12mm nut holding the Y to the intake plenum. You can PM me tomorrow if you get trouble, I'm in all day. I've done it f**@**g loads of times now. Quote Link to comment Share on other sites More sharing options...

Rob Posted May 16, 2008 Share Posted May 16, 2008 Oh yeah, forgot the water pipes to the TB. You can run a bypass pipe between those, front and back for a little mod that keeps your TB running a bit cooler in summer. Those at the start who said easy job, just a 12mm spanner, I suspect have never done it. Quote Link to comment Share on other sites More sharing options...

Mike M Posted May 17, 2008 Share Posted May 17, 2008 They can be changed without removing throttle bodies and stuff if you have a good amount of patience. Quote Link to comment Share on other sites More sharing options...

Guest banjo_quint Posted September 5, 2008 Share Posted September 5, 2008 I know this is a bit out of date, but this post helped me out so I thought I'd add this here. Like the man said, you don't have to take the throttle body off to complete the plug change. It's only two plugs that would require this and it's worth investing in a couple of tools to avoid having to change gaskets every time. You obviously got the plug socket, all you need after that is a UJ adaptor and a long extension for it. You need to tease the condenser caps off, don't be brutal with them no matter how much they ask for it, because the rubber is soft. Plug 4 (counting from the front), you also have to disconnect its lead from the distributor, this creates enough play to allow you to pull the cap away from the plug, it has to pulled towards the bulk head to get it out. And then it's all over bar the shouting. See pics. http://www.renegadedesigns.co.uk/images/DSC02588.JPG http://www.renegadedesigns.co.uk/images/DSC02591.JPG http://www.renegadedesigns.co.uk/images/DSC02589.JPG Quote Link to comment Share on other sites More sharing options...

The turning circle of the wrench will be shortened a lot due to the throttle body. I actually find it easier to take everything out and give the parts a good clean and polish while out.

Mike M Posted September 5, 2008 Share Posted September 5, 2008 I managed to get away with using a wobbly extension giving the socket that little bit of movement it needs. I'm sure it took just over an hour to change all six, was a long time ago now like. Good effort though, nice to see someone else having a go.

Didn't find a problem with the turning circle on the socket at all, that last one under the throttle took the longest due to having to wiggle the socket about to get it on, but otherwise pretty straightforward. Took about 45 minutes in all. Quote Link to comment Share on other sites More sharing options...
