Did the belt already break, or is the water pump making noise? Reason I ask is because your 1st-generation LS has a non-interference engine, meaning if the belt breaks, no damage will be done to the engine. If you don't travel out of town much, you could always just wait for the belt to break. Although my local mechanic says, in his 20-year career, he has never seen a timing belt on a Toyota vehicle break. Fords are another story. ;) I have a related question. I have a Camry and the timing belt broke on it twice, once after 90k miles and the second time was after 40k miles on a new timing belt. What is troubling is the time that it broke after only 40k highway miles. The mechanic that fixed it was an old Toyota factory trained mechanic. He told me that if a mechanic doesn't install the timing belt correctly, then it could be prone to snapping. He also mentioned that he thinks that LS400's have a "self tightening" feature, whatever that means. I have 3k miles on a new timing belt on my lexus ls400 (95) and I am a hoping that I won't have a problem. I used all Toyota parts. Has anyone had a problem with the timing belts snapping before the recommended change intervals? I didn't have the work done at a dealer, but at a local garage. So, my concern is if a less experienced mechanic put on the belt, would this potentially cause me problems or are timing belts pretty straightforward and not considered a difficult job? Hi, I also have a Camry in addition to my LS. It is a 2000 with 67k miles. I have never changed the timing belt due to it having a non-interference engine, and I do not drive the car out of town much. The mechanic that installed the second timing belt on your Camry may not have used Toyota factory parts. That could have had something to do with the belt breaking. The other guy was probably referring to an automatic tensioner when he said "self tightening". It is good that you used all Toyota parts when the belt was changed on your 1995 LS. Most belts do not break on their own before the recommended replacement interval. However, the water pump on the LS, and most other Toyota vehicles, is powered by the timing belt. So if it is in poor conditon and siezes up, it will take the belt with it. Driving agressively can also cause the belt to wear faster. Changing the timing belt on any car is almost the opposite of straightforward and easy. There are marks on the Toyota-branded timing belts and the car's engine to line the belt up correctly. The mechanic should have seen them and used them to make sure the belt was aligned properly. Remember that starting in 1995, the LS came with an interference engine, unlike the Camry. So do not wait for the belt to break on it. It does not sound like you would on any of your vehicles though. Tom said "starting in 1995, the LS came with an interference engine". Does this mean all LS430 need to change the timing belt before it break otherwise engine will be damaged? I just bough a 2004 LS430 with 85K miles on it - should i be worry & should i need the timing belt and water pump services soon. Please, comments Regards, Michael

Hello Everyone, I did fill up both ls400 & ls430 tank with regular unleaded last week - but i am wonder that it will hurt the engine in the long run. Please, comment Michael

89-94 LS400 has evaporator problem since its design was lack of air filter. Overtime, dust get into the evaporator and itself a/c moisture tend to rush the unit then start leaking. When your A/C blow out some kind of death towel smell then about time to replace the evaporator - it is under the passenser compartment. You can do it yourself - it takes about 2-3 hrs labor - my cost about $400 for part and labor - HINT: try to deal with the mechanic by the job but not the hours. When you do this, i recommend to replace all the O ring. Good luck By the way, it is a beautiful car and what a great prize you got. :o :o :o :o :o :o :o :o :o :o :o

B) Wow - 500K miles - very impressive - mine is rookie - 92LS400 with 169K miles - However, i have changed some major like "Starter, Alternator, Timing Belt, Water Pump, A/C evaporator". She is healthy and strong. Dezzy, go for another 500K miles then sale back to Lexus - they are definitely buying back from you for their advertisement. How about one dollar for every mile you have on the car:lol: :D :D :D :D

hi .. im new to this website. i was wondering if these 1992 LS400 electronic fans connect to A/C evaporator electronic circuitry (under the deck - by the passenger side)? The reason i am asking because my car just got an evaporator replacement by the shop and i noticed that the electric cooling fans are no longer work when A/C is operating. Should they be when the A/C is turned on? If i remember correctly these fans should have low RPM whenever A/C was on in the past. I did 1/2 hour driving test this evening with the A/C full on and the fans is not moving at all. Please, help - i am just afraid the mechanic, who has worked on my car, did not installed the evaporator correctly. I also test it by keeping the car on while it was on park and turn the ac to full and kept about for 1/2 hours then pop the hood and saw its still not working. Please, help - Thank you all !
