    I have a 1986 Toyota Corolla GTS Twin Cam. I need to do a valve adjustment on it as it makes some noise @ about 3000 RPM. Does anyone know what the valves are to be adjusted at?

    Hello friends,
    I have a problem with my toyota carolla. 4 months back i got a over heating problem so i went to mechanic and he told me to change the thermostat and water pump.. i changed them but it didnt work.. so he told me that may be due to malfunctioning of sensor. i have neglected in changing the sensor. i usually drive 60-80 miles daily.. (30-40 at a stretch)..4-5 days i didnt get any problem on 5th day i have listened a vibrating sound as i am increasing the accelaration, after some time it stopped. this time also the arrow is showing over heat.. and this happened twice(stopping).. after that i went to the same mechanic and explained my problem he told me to replace the radiator.. i have replaced the radiator. after that over heating problem is solved... but after this my car is began to jerk ( one of my fren told me that it is because of new belt that is used when u replace the water pump) when i am stopping at the signals.. and i can also hear the the same vibrating sound as i heared before but this time car is not stopping.. what i observed is car accelaration fall down.. when i want to increase the accelaration the sound is becoming lowder.. so i am just utilizing the downs on roads to accelarate my vehicle... these days my car is taking much time to start, i have to accelarate to start the car.. and it cant able to run 50 miles at a stretch.. (sound is increasing after that) this sound is coming only after the heat point comes to the middle.. this is my problem..

    can you please suggest an idea, i am a student and i cant afford much on it.. like taking it to dealers..

    I have a 2002 Corolla S with the manual transmission. The car has 80k miles. Lately I feel that the clutch is engaging closer to the top of the release. Is this a sign of clutch wear or is there an adjustment? I went to a mechanic and he says that model year has the hydraulic clutch so there's no adjustment needed. Is that correct?
  • mcdawggmcdawgg Posts: 1,668
    Corollas have had hydraulic clutches since at least 1984 - no adjustments. As long as the clutch is not slipping (one test is trying to accelerate in 5th gear up hill at a low speed, like 25 mph), you are fine.

    Did you figure out this problem? I have the same problem.
  • I have two oil change questions.

    We have a 2009 Toyota Corolla LE which is 4 weeks old.

    Question 1: Should the oil be chnaged at 1000 miles to clean out metal debris?

    Question 2: Should synthetic oil be used thereafter?

    Thanks. Phil

    No I would do a first oil change at the recommended time and then switch to synthetic oil. This will give the seals time to get good and set.

  • My car won't start...it doesn't do anything but the radio works so I know it's not the battery and I guess not the alternator. The day before it clicked and hesitated before starting. Does anyone think I need another starter and is that under maintenance? Would a new starter be covered under my warranty. I have 38000 miles on my car. I only go to work and come home which is why I'm surprised that my car won't start. And if it's not covered under warranty how much does a starter and labor costs. I really don't have any idea. My grandpa died last year and he helped me with my other cars that needed service. This is my first new car so I haven't had any problems until now. Help my funds are low and my kids start school Thursday, gotta get this fixed fast and cheap.
    :cry: :confuse: :sick:

    More than likely, it IS your battery...probably a dead/shorted cell, which will not function under a heavy load, such as starting....but, will have enought power to run accessories.
  • terceltomterceltom Posts: 1,017
    I would have to agree with Bursiris that it's your battery. My 2001 Corolla original battery just had to be replaced last week with the same symptoms your speaking of.
  • I wouldn't worry too much about the clutch unless it slips. With proper care, the clutch will last for many more miles (My Aunt has well over 200M miles on the original clutch....WOW!!!) She has had no major problems to speak of whatsoever!!

    I do have 2 questions;

    1. How often should the transmission fluid be changed with the manual?

    2. How often should the antifreeze be flushed/changed?

    ****I have a 2005 Corolla S.

    JUST LOVE THOSE COROLLAS!!

    Hello to all, with the corolla vibrates problem, as you may remember I had that problem with my 98 corolla, I tryed every thing to solve it but change the tires because they were good, well now the tires wore down and needed changed, So as I put 2 new tires on the front of my corolla, now there is no more vibrating problem, Solved and wanted to let all know it does not matter how good your tires look, they can still cause vibration.
  • sunilbsunilb Posts: 407
    kind of urgent, and I've been looking in the engine bay and searching online to no avail....

    Does anyone know where I can find a raised VIN in a 1994 Corolla??

    Please let me know.

    Thanks!
  • I have a 2007 corolla, less than 2 years old. I was waiting at a signal, and once green i gave it some gas - IT LUNGED FORWARD , just JUMPED. Immediately the service ENGINE light came on.

    I drove slowly after that, but everytime I had to accelerate, it would lunge forward.

    Never had any issues with it before this :( Called the dealer, they said it could be something wrong with the COMPUTER

    Any suggestions ??
  • For the past few days, my A/C has been making a "ticking" noise whenever it is turned on. At first, I thought it was something in my glove compartment, because the noise seems to be coming from my dashboard. It only makes this noise whenever the A/C is turned on. Does my air conditioning filter need to be replaced? I think the fans might be clogged with dirt or something. It almost sounds like something is caught in there. I only have 22,000 miles on my car so I really hope nothing is broken. Thanks.

    Any suggestions ??

    Take it to the dealer and let them diagnose and fix the problem. If it's under 36,000 miles the repair should be under warranty.
  • Thanks all for the updates. I did take it to the dealer - they said it was a known problem with the Corolla - the ECU Computer was faulty :mad: .
    They replaced the same with a new one, since it was under warranty free of cost :).

    The dealer mentioned she received 3 Corolla's yesterday with the same problem :surprise: .

    Hmmm... seems like a recall might be in order.
  • Hello,
    First off, how many total miles are on your car? If you are over 100K, to solve the acceleration problem you probably need...
    A) Timing Belt replacement - VERY important, a little expensive but usually needed every 90K-100K miles.
    B) Front Axle replacement- it could be popping in and out of your transmission causing the noise and slipping.
    C) New Transmission -** Get more than 2 opinons before you replace your transmission - most transmission mechanics are LIARS.
    Good Luck!
  • mcdawggmcdawgg Posts: 1,668
    1998 and newer Corollas do not have timing belts - they have chains, no maintenance required.

    I have a 02 corolla ce and I noticed that the daytime running lights will not come on.
    My headlights work just fine including parks and they still come on by themselves.
    I checked the fuse and relay under the hood and they are fine. What else could I check that could be causing the problem?
    thanks
  • Hallelujah,

    Thats one of the greatest advancements on the Corolla. Does Toyota still use timing belts on any of it's products?
  • mcdawggmcdawgg Posts: 1,668
    Few, if any, and if they still do, they won't soon, because all of their new engines use chains.
  • My 2006 Corolla with 52,000 has a computer glitch. A part in the computer will not read the chip in the key all of a sudden-they are not comaptible now. The car starts then dies within 5 seconds. The dealer has to order a part today and install it tomorrow or Wednesday. Is this covered by the Drivetrain warranty-5 years or 60,000 miles or where do these computer issues fall under? Is this a common issue, should there be a recall?
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,116
    No I don't think it's a drivetrain warranty issue, but that's just my two cents. Toyota has the final say.

    There won't be a recall because it's not a safety related issue. There isn't even a Technical Service Bulletin on it, so this is apparently not a common thing with Corollas of that year.

    Cars that fail to read the key chip are legion, if you read the complaints all over Edmunds, for various makes and models. I think what happens is that somehow, through corrosion or whatever, the computer no longer reads the proper resistance in the chip.

    Have you tried cleaning up the key at all?

    I've heard of a trick on GM cars where people install a resistor equal to the key's resistance value, right into the ignition circuit as it exits the steering post, and this essentially by-passes the whole silly thing.

    Recall???? This is the very first time I have even heard of this problem on this Toyota forum, aren't recalls and service bulletins reserved just for common problems that a number of owners are having with the same issue? Recalls are not issued for such isolated problems.
  • Is this what is called a ECU-when the computer does not read chip in key? I am very unknowledgeable regarding cars, is this called a Electronic Computer Unit in the vehicle? If it is, there is a post in Maintenance, Recalls and TSB on Edmunds regarding the issue I am experiencing with my 2006 Corolla. It states that there was a ECU Flash Reprogramming procedure. I do not mean to be ignorant, I am just trying to understand.
  • Mr_ShiftrightMr_Shiftright CaliforniaPosts: 45,116
    I think that relates to a driveability issue. The ECU could conceivably not be reading your key correctly but more likely the key device is defective. One always goes to the simplest explanation first is what I mean, in any good diagnosis. The chip in a sense gives the ECU a signal. No signal, wrong signal, no GO!

  • Hello,
    I bought a used 2000 Corolla about 6 weeks ago from an individual. Since then I've had a new alternator and a new battery. Then my oil light came on and I had to get towed. They found a lot of sludge on the oil screen which they cleaned off and then told me to get the oil changed more often for a while to clean it up more. Now, a friend's trusted mechanic tells me the sludge is still a big problem and there has been damage to the engine. My plan was to drive to the heart of Mexico where I live much of the year. Now I feel nervous about making the trip. The mechanic says the engine could go at any time. He doesn't seem to be trying to sell me anything and doesn't recomment any repairs.

    I am wondering if there is anything I can do to make the car safer? He says the damage is already done. Or, do I just have to call the car a lost cause and sell it to someone who isn't planning such a long trip? Or, do I drive to Mexio hoping for the best?

    Any thoughts would be appreciated!
  • Thanks for your advice and brainstorming on my issue. The dealer said that the immobilizer had to be replaced and thank goodness it is under warranty...how lucky am I? What do you know about an immobilizer? Thanks!
