  1. The timing belt keeps the crank and cams in time with each other so yes if the belt breaks the valves go out of time with the pistons. Interference means the valves and pistons can touch each other and non-interference means they won't. Nearly every Toyota engine that uses a belt rather than a chain is non-interference.
  2. From what I understand the 2JZ series of engines are all non-interference.
  3. If you pull the EFI fuse, you don't have to reset anything! <_< ← You also have to pull the ECTS fuse on a series II as the ECU has two power sources. It's in the workshop manual and also can be confirmed with the wiring diagrams. ← Colin, ECTS fuse, series II?? Over my head in acronyms..please explain! Thanks ← ECTS fuse is just one of the fuses in the engine bay which provides power to the engine ECU. If you want to reset the ECU you must remove this fuse. Series II, Mark 2 - the second generation of Lexus GS 1998-2005. http://www.lexusownersclub.co.uk/knowledge...ex_v2&id=35&c=3 If you want to reset the transmission then leave the fuses out for 5 minutes or more.
  4. Make sure you get the correct ones. The RX uses air/fuel ratio sensors rather than standard oxygen sensors.
  5. If you pull the EFI fuse, you don't have to reset anything! <_< ← You also have to pull the ECTS fuse on a series II as the ECU has two power sources. It's in the workshop manual and also can be confirmed with the wiring diagrams.
  6. It will eventually learn your driving habits, however it's quicker to pull the EFI fuse. <_< ← Workshop manual states the ecu should be disconnected for 5 minutes to clear the gearbox settings, easiest way is disconecting the battery. The engine settings are quickly cleared by pulling the correct fuses (EFI and ECTS) for 10 - 30 seconds.
  7. seatbelts stretch in an impact, try watching some crash test videos
  8. The wiring is not there on the IS series either.
  9. Hopefully just Denso these days otherwise the plugs you are using are nearly 10 years old as the company changed it's name in 1996 :P
  10. Do they only use synthetic oil in the hybrid vehicles?
  11. Denso ones are mainly used as OEM because Toyota owns part of Denso. The failed plugs I have heard about on the UK forums have been NGK, so I stick with Denso.
  12. The RX (harrier) is available with a 2.4l engine in Japan. Just add the hybrid system and you have your RX330h with excellent mpg. The 400h is more about power than economy.
  13. I guess they don't expect people to be filling up with only 3 or 4 gallons at a time. The only solution is to fill up with at least 6-8 gallons at a time.
