  1. Hey TexasLExus94, I have replaced my ACV (air control valve). I had to buy a stuby 17mm open end wrench to loosen it. The only place I found this tool was at Sears but you might be able to locate in another store. When loosen. be carefull when removing as fluid come out of there. Be sure to cover the alternator as to prevent any fluid from getting into it. I do not know if it makes a difference, but I marked the hoses to install in the correct way. Also you need to bleed the power steering system after installing ACV and adding ATF Dextron II fluid to proper level(due to loosing after removal of ACV).
  2. Congrats on your new purchase and I welcome our new members to LOC. Just sit back an enjoy your LS, as I have enjoyed my 91.
  3. Are the strut bars different on a 97 vs 90-94 model? If not, then they are much easier to replace. Please press link for instructions on how to remove. This is in Lextreme's website.
  4. You can try ebay or auto dynamics. There is another company that carries them just can't remeber. :P
  5. Hi Wilfred, The water drops are normal for the A/C system. This is coming out of the drain tube in the front near the firewall correct? Now, as for the hissing, I don't know what that could be.
  6. :D Great article LEXLS!! Now I can see the evolution of one of the greatest machines in the world.
  7. Hi Mia, Sure they make it, try this, they carry a kit for the 90-94 LS400 as well as the wiring harness so you don't have to cut any wires. The Install kit number is LX3 and the wire harness number is TA02 As for aftermarket brands: try Alpine, Kenwood, Clarion, Nakamichi, Sony, Eclipse, McIntosh, Pioneer, Blaupunkt to name a few. Leo
  8. This also happened to me. Make sure your oil level is up to full. Many shops when doing an oil change automatically think 5qrts of oil is all you car needs, but in reallity it needs 5.6qts of oil. Just add a half a quart and the light should go away. Or maybe your low oil sensor switch is going bad, give it a try and post back your results.
  9. No, Dextron II and Type II transmission fluid is not the same. I learned this the hard way. I went to my local Jiffy Lube center and asked that same question, and of course they said yes as I wanted to do a transmission fluid flush (remove all old fluid and add new). Well after they were done I took my car and noticed that my transmission was shifting harder. I immediatley called my friend's friend, who by the way is a Lexus master mechanic and asked him about this, and he suggested to immediatley change out the fluid, as the fluid recommended by Lexus is a synthetic type fluid, Type II, where as the Dextron II is not. This can harm the transmission in the long run. Had to buy 16 quarts of Type IV, replacement for Type II, to have the whole transmission reflushed again. After that, my transmission was back to normal. As for your coolant, in your owners manual says to use a good brand of ethylene-glycol, more than 50% of ethylene-glycol, but no more than 70% is recommended. But to be on the safe side, just buy the exact type from your local Toyota dealer as it is cheaper than the Lexus dealer.
  10. No problem, here to help out all Lexus brothers/sisters. :D
  11. You might have a bad courtesy light switch. Switch that pop out when you open your door to turn interior lights on. You said that even when the door was unlocked and you open and shut the door the door locked. Look at you interior light the next time it does this. If you light is off, that is why you locks are locking, which tells you that your switch is not opening far enough, which causes your keyless system to think the door is closed sending a pulse to lock. I had this happen to me also, all I did is removed the switch, removed the rubber cover on the switch, sprayed some W-40 into the spring contact, push on the switch a few times, re-install rubber cover and re-install. Problem solved. If this does not help you, then you need to replace the faulty switch.
  12. Very touching video :cries:, excellent choice in car. :D
  13. Don't know anyone in LA county but check this place out.
  14. They started to have dual airbags in 1993.
  15. J4649 - This also happened to me and it turn out it needed some oil. Add a half a quart and the light should stay off. Just a note these cars require 5.6 qts of oil. So if an oil change was done recently, most cars only take 5 qts and thats probably what was put in.
