  1. The IACV worked out pretty well. I had a problem removing the valve cover and since I was running out of time, I had to reassemble everything so I can use the car the following day. The IACV is the part that is under the right side of the throttle body. Check out this thread for details (its on the RX but...you get the idea).. http://us.lexusownersclub.com/forums/index...c=30723&hl= I will say that on the ES, its much easier to remove the entire throttle body and flip upside down and remove the IACV. Its just 3 bolts to remove, some vaccum lines and some other tubes that are clamped on. The 4 screws to actually remove the IACV are on pretty darn tight and you most likely will need a vice grip and you will want to replace them with bolts afterwards. I think I will attempt the valve cover gasket job again once I figure out what I was doing wrong.
  2. I got to the point where I was removing the rear valve cover and I couldnt do it. In the front of the of the motor (on the passenger side) it appears that there was a metal cover that the valve cover needs to clear. Im convinced that this needed to be removed. Since I needed the car operational tomorrow, I put everything back together. I used a little RTV where the valve cover was leaking. Does anyone know what I am taking about in the front of the motor? Seems there is a metal bracket / cover for the camshaft pulleys or something. If I can figure out what the procedure is to remove that cover / bracket or whatever it is, I may attempt again.
  3. Was this at the dealer and OEM parts? Was the transmission serviced? ever?
  4. You can go to the dealer and get the key for your car. There are several different ones for each model so they will be able to tell you which one is on your car. You can get the key separately from the set which comes with 4 lug nuts. Dont let them try and pull a fast one on you and tell you that you can only order the set. This is not true.
  5. The car does not need the battery to run, only to start. You should be able to disconnect the battery from any running car and the car should stay on. The function of the alternator is to provide electrical power to the car and charge the battery. This is how to you can test your alternator. If you disconnect your battery and the car shuts off, it usually means there is something wrong with the alternator or there is another electrical problem. If this happens randomly while driving, could be a lot of things. Hopefully its not something major.
  6. I would do the 90K service / timing belt / water pump / seals. I would also plan on cleaning your IACV (by yourself) or replacing at the dealer (which is expensive).
  7. my changer is in the glove box...what year is your ES?
  8. Hello fellow owners...just wanted to post something about the job I am doing...I am still in progress and hope to complete tomorrow. So far, I have removed the throttle body and air hoses, removed the IACV from the throttle body and removed the intake manifold. What a job! I had never worked on this before, and I didnt really have all the right metric sockets and wrenches for the job. I do now :) Made several trips to parts store and hope depot. Got two nice little cuts on left hand. I will update this thread with more information, however I just wanted to post as much as I could tonite before I forget. In terms of tools, definitely needed 12mm 13mm 14mm open wrenches and sockets and 14mm short socket for the bolt that connects the rear of the intake to the support bracket. I actually started off trying to remove the round part with the butterfly that connects to the air hose, which is right on top of the IACV. I realized that this was wrong and I have to remove the entire throttle body. I removed a lot of the tiny vaccum lines to move these big parts out of the way so I can access the valve cover in the rear. I am somewhat concerned that when the go back on they may not be as tight as they were previously. Does anyone have any suggestions / comments about this? I may just buy some tiny alligator clamps and secure the lines. Also, I noticed that the valve covers bolts were not as tight as I expected. I would say it was 1 notch tighter than hand tightened. At the dealer when I purchased the gaskets, I asked them if there were any torque specs. There were a few service guys floating around and they said to hand-tighten them. They were nice enough to give me diagrams as well (which was not expected). The 4 screws on the IACV were a !Removed! to remove as everyone else who has post about this mentioned. I was only able to get one of them off without a vice-grip. I definitely plan on replacing these screws with hex-bolts. Definitely had coolant leakage as expected. I read something about first starting up the car after the IACV was cleaned. Something to the effect that it may take a while for the car to re-calibrate the IACV. Any comments on this? Felt good to turn them wrenches. I hope everything works out tomorrow. Thanks to all for reading.
  9. Was just told today there is no EGR on this car. Timing belt is scheduled for 90K although not sure this is your problem.
  10. I always hand tighten my anti-theft lug nuts and I instruct all mechanics to do so vs using the impact wrench. You can get it pretty tight, and getting off wont break the key for the locks or strip the lock itself. Bottom line is, if a thief wants to steal the rims / tires they will. There are plenty of ways to get them off without the appropriate key. The anti-theft lug nuts are a good to ward off the lazy theives.
  11. Thanks for the encouragement...may try to tackle this one after done with IACV cleaning.
  12. Apparently this happens when you swap / disconnect your battery. Happened on my car and I asked the dealer to fix it and they did no charge. Its a simple reset on the computer (I think). You may get lucky if you can find a dealer or private mechanic that is being nice.
  13. I bought a 2000 ES 300 4 years ago from a dealer CPO, and I was glad I had the warranty. I didnt have any major issues, but I feel I did get value from the additional cost of the CPO. I did have to replace the rear suspension which was covered, and everytime I went to the dealer, I was treated better for having a warranty. In terms of buying a 2000 today, I agree the warranty wont be worth much. I also agree with the other posts. Make sure and verify the service records. After 90K, there is a lot of stuff that could need to be done aside from the timing belt. I just did a major service 90K / timing belt / water pump / cam and crank seals, and now I am having issues with the IACV which seems to be pretty common with these cars. This is a $285 part that hopefully can be cleaned as suggested by the good folks here in the forum. I also have leaking valve cover gaskets which the dealer wants $400 to change. My point is, you are buying a old machine and buyer beware. No matter how good of shape its in, it will have issues, and unless you are a mechanic, you will have to spend some dough. For around 15-17K, you can buy a brand new scion, which is also a toyota, and will be completed covered under warranty and have piece of mind. Food for thought.
  14. Im going to be undergoing this project based on GoldenStateSilverSport's post http://us.lexusownersclub.com/forums/index...723&hl=IACV I did see a few mentions in other posts about the EGR and the TPS and wondering if I should be concerned about it. I would like to clean the EGR, however not sure where it is same with the TPS (not sure if my model has the TPS). I saw the warnings about the cleaning fluids and to use non 02 sensor damaging stuff. I also did see the warnings about the tight screws from the factory, so I will be watch out for that. Is there anything I should be concerned with? Thanks in advance. Just shelled out $1500 for the 90K service, timing belt, water pump and cam/crank seals. Looking forward to getting down and dirty, and then clean and saving some flow of course... :) Cheers -Rob
  15. When you say vintage, what year is it? I plan on doing this procedure on my 2000 es 300 and Im wondering if I will have to mess with the TPS and EGR. Thanks. -Rob
