    Actually, the actual timing belt can be put on anyway, but the camshafts are what arent alinged. Look down the side of the engine and the crankshaft pully. You should find a place somewhere that has marks with the numers TDC or O, then 5, 10 and 15. Rotate the crankshaft or bump the starter until the TDC or O mark is aligned with the mark on the crankshaft pully. Now, look at the camshaft sprockets and rotate them until the two dots are aligned. Basically, check all the dots and lines are aligned. Just to let you know, i may nt be exactly right but that is what it is like on our camry. Buy a repair manual for your car.

    I have checked and rechecked to make sure the belt was lined up right and that i had TDC. Could it be that the pully looks like it is lined up but the harmonic balancer-pully has spun throwing the timing off
  • penizzlepenizzle Posts: 104
    Rotate the alignment marked sprockets another turn or the crankshaft another turn. To prevent this from happening next time, align everything before working on it. I've had that problem and rotating some stuff again and aligning it fixed it. The pullys do not affect the timing. You need to get a manual from online or at a local auto store. The only thing affected that has to be the way it was before are the crankshaft oully, and the camshaft pullys. The oil, water and other plain oullys do not have to be any way. Make sure the new belt is instaled good and is spinning when cranking the engine over.

    I did all that when i took it apart and put it together. I have been working with a mechanic that knows all that. Our problem is that he is a GM mechanic and does not know that much about Toyotas. What we did not know is if there were any other problems that were common for Toyotas. When we put it back together TDC or the crank and cam dots were lined up the way the manual said to, but the timing was way of. we checked the timing and it was at zero. According to or manual or what we found is that the timing is to be set at 10. So we turned the distributor to adjust the timing the way the manual said to do,but we could only get it to 9 1/2. It runs a little better, but it still runs rough and heats up after a little run time. We have checked the belt to see if it was the same as the old one. We have also checked the harmonic balancer which is also the crank pulley to see if it had slipped.-( we matched it to a new one) Everything that we have checked seems to be fine. Thank you for all the help so far, but is there anything anyone can think of that we might have missed?

    jdday,

    I would like to know if you were able to resolve your problem with setting timing. I have 93 Camry and I am having exactly the same problem setting the timing after installing water pump and timing belt. The car starts and idles fine but has absolutely no power at all. Been through it twice now and haven't had any luck. any help would be appreciated.

    Took my 2000 LE V6 for an oil change at 83000 miles. The car is generally in excellent mechanical condition. The service advisor noted that I have a valve cover leak ($650) and I am due for a timing chain and water pump replacement ($840).

    There have previous instances when the same dealership in Northern VA recommended service work that was questionable.

    Questions:

    1. How cam I check for the valve cover leak if there is no visible oil leakage under the car?
    2. When is the timing belt supposed to be replaced? I understand that replacing the water pump makes sense concurrent with the belt replacement.
    3. What is a reasonable price for all this work? I have a feeling I am being over charged.

    Thanks!

    High mileage Camrys of that vintage tend to seep (ooze?) a little from the valve cover gasket. If there's no visible leakage, it's a pretty minor problem, imo.

    Toyota recommends changing the timing belt at 60k miles for vehicles normally driven under "severe" category usage, i.e., taxi cab, police, constant stop'n'go driving, etc. People differ about the need to change the belt under normal driving conditions. It's true that a broken belt will be an unpleasant and expensive experience.

    The prices quoted are well above what a quality independent garage would charge.
  • lzclzc Posts: 483
    I should add to my above note. While Toyota's 60K timing belt service applies to vehicles in severe usage only and dealers have adopted that as the "recommended" service interval for all vehicles, your car is about 14 years old. That counts for something, too. Changing the belt would be the safe thing to do.

    )) "...your car is about 14 years old." ((

    sambo49's model year 2000 Toyota Camry is about 14 years old? No matter... sambo49, be aware that some engine designs exhibit "interference" between pistons and open valves in the event of a timing belt failure while running. Moving pistons striking a stationary open valve extending down into the combustion chamber in the event the timing belt breaks will result in a bent or broken valve and possibly a broken piston. In an extreme case, connecting rods have been known to fracture, too, and result in busting a hole through the lower side of the engine block casting. (When that happens, it's replacement engine time - which might well wipe out most or all your car's current market value.) I don't know whether your Camry's engine is an interference design, but if there are four "dimples" cast into the piston crowns, it would be considered such. You'd probably need to call a Toyota dealership's service department for confirmation on this point. At 80,000+ miles on the original timing belt, consider replacing it an investment in continued, reliable service from your car - you're already 33% into borrowed time. The cam cover gasket oil seepage is probably a minor issue that the dealership's service department is attempting to scare you into unnecessary makework. Unless you observe actual oil loss on the dipstick from the "Full" mark to the "Add Oil" mark or lower over the course of your usual oil change interval, f'gedaboudut. ;)

    >>>sambo49's model year 2000 Toyota Camry is about 14 years old?

    Hmm, somehow I thought it was a '93. Must have been thinking about another car. Sorry.

    The 2000 Camry V6 has a non-interference engine, so your horror story doesn't apply. As I said, people will differ over the need to replace the belt. Toyota dealers, of course, are one mind on the subject. Somewhere around the year 2000 Toyota changed the recommended mileage for a belt change to 90K when driving under severe conditions.
  • sambo49sambo49 Posts: 36
    Izc,

    Not a problem, I believe the message right before mine was a 93 camry. Thank you very much for your reply. I will replace the timing belt at the next service since I intend to pass this car to one of my kids in college and he will need reliable wheels...
  • sambo49sambo49 Posts: 36
    Ray h1,

    I will replace the timing belt at the next service and hold off on the valve cover while keeping an eye on the oil level.

    I checked the engine again today and could not find any visible signs of oil leaks, just dust and grime acculmulated over the years and 80+ k miles.

    Many Thanks!
  • Your response is of interest to me. I have a '99 4-cyl. Camry with 106 thousand + miles and am tempted to continue to defer getting a timing belt replacement. Any way you know of to find stats on the track record of timing belts among Camrys of my vintage?
  • 210delray210delray Posts: 4,722
    I don't think any such stats exist. For one thing, belts don't even show visible wear for the most part -- they just break when you least expect it.

    So, you really ought to have it replaced now. I assume you wouldn't like to be stranded somewhere if the belt breaks, because the car instantly becomes undrivable.

    I'd look around for a good locally owned independent shop that can handle the job. Ask friends, relatives, and co-workers for recommendations. You don't have to go to the dealer, who will charge the proverbial arm and leg.

    I also wouldn't trust the chain places (tires stores and discount stores).
  • The Toyota dealer sent me a notice that the timing belt should be replaced at 15,000 miles on my 2006 Camry, for $180. Based on this forum, that sounds a little early. Should I do it now or not?
  • 210delray210delray Posts: 4,722
    Are you sure they said timing belt? At 15K miles?

    If you have a 4-cylinder, there is no timing belt to change as of the 2002 model year, just timing CHAIN that should last the life of the car. If you have a V6, there is a belt, but the replacement interval is 90K miles.

    $180 is a good price, though!

    Run, don't walk away from that dealership!
  • 210delray you must be a toyota mechanic to know so much about these Camrys. I thought my 05 LE I4 (2AZ-FZ) had a belt not a chain. I looked at my owner's manual and sched maint book for any mention of a chain vs belt. The manual (under Sevice Specs) mentions the 1MZ-FE and 3MZ-FE drive "belt" tensioner is measured by a Borroughs gauge, but does not say anything about the 2AZ-FE (4cyl) having either a belt or chain. Your info will probably save me lots of money in the future because I was convinced I had a belt not a chain. The Sched Maint book says change the belt of the 1MZ or 3MZ at 90k. I guess I read this section too fast. Thanks for the info. I guess I need a Camry shop manual. Any suggestions on which one to buy for a shade tree mechanic?

    I have a crack in my timing belt and it needs replacing. I have been quoted $550. is this a little to steep?
  • djm2djm2 Posts: 705
    QUESTION:
    Does a 2007 V6 Camry have a timing chain or a timing belt? ---- If it has a timing belt, when does it have to be replaced? -------- Best regards. ----- Dwayne ;) :shades: :)
  • My dealer said my '07 I4 has a timing chaing and that it won't need to be replaced (at least during the terms of my lease.

    I would think probably around 100,000 miles......let me know what you find out.

    Hi,

    I just bought 05 Camry LE with 30K miles on it. I am thinking about taking this car to have checked at dealer for 30K maintenance. What needs to be done ussually and is it a good idea(in terms of quality of service and cost etc)?

    And what is usual durable stuffs that needs to be replaced regularly(i.e. 5k or 10k?)? I will be taking this car out of country where there isn't Toyota dealership so hoping to buy some stuffs and take along. Thanks.

    p.s. I see a lot of discussion on timing belts. On 05 model, is it belt or chain? And how often does it have to be replaced?

    Regards
    J

    The 2001 4cyl 2.4liter Camry engine and forward has a timing Chain.

    The 2007 3.5 Liter v6 engines has a Chain. The 3.0 and 3.3 liter engine on the SE has a belt.
  • gunga64gunga64 Posts: 271
    I think it is time for you to change timing belt at 92000 miles. It's about $50 for part and 2 hrs labor. They asked $230 that is little to high except replacing water pump and other belt(s) as well including in the price.
    You could check condition of your timing belt by opening plastic cover for inspection.
    Make sure that you check their works after installing new belts. It happened to me that the belt for water pump was so tight caused water pump bearing failure after 4 months later. After they changed water pump, then the air conditioning bearing making noise ...


    Just thought I'd bring this topic up. I am contemplating having my timing belt done. But I fear the above happening. I had nothing but problems with a corolla I had after a timing belt change. In fact the harmonic balancer snapped months afterwards. It's almost like let the belt break on its own, as long as non-interference.
  • i met someone who said she had just received a notice from toyota that there is a recall for 1996 toyota camry timing belts. I am the 3rd owner of a 1996 camry so know little of its history of repairs. with 110,000 miles i assume i better get it replaced very soon.
    is there any indication before it freezes up? there is grinding sound when i excelerate. Is this related to the timing belt?
  • 210delray210delray Posts: 4,722
    There is no prior warning as to when a timing belt is about to let go. Even when you replace it, it's hard to discern any wear on the old belt.

    Check with a Toyota dealer or NHTSA for possible recalls relating to the timing belt.
  • I have a Toyota Camry (97) I have had less than a year... bought it from a client of the law firm I work for... great car...very reliable...doesn't leave me hanging...yet. I am paranoid that "her" timing belt's gonna go and I am going to be screwed...I went on some website to find out warning signs but then someone else told me when it goes, it goes...you basically can throw the car away after that...I dont want to go that extreme...I'm at 88,000, need an oil change and query whether or not its just in need of a tune up...seems kinda' sluggish at times...any advice?
    :confuse:
  • who told you that (there is no prior warnings to when the belt is about to go)??? If you go on the website: www.castrol.com/castrol/ you will see a site that has "expert car advice" with archived articles and a link in it refers to: "When Should You Replace a Timing Belt?
    Belt replacement varies by vehicle make and mileage. Check your owner's manual for suggested maintenance. Here are some warning signs that your timing belt might need to be replaced:

    Rough idling
    Chattering and other strange engine noises
    Difficulty starting the engine
    Even if your car is "symptom free" it's still a good idea to check the timing belt regularly."
  • 210delray210delray Posts: 4,722
    Those symptoms will likely not manifest themselves until well past the normal maintenance interval. When I had my former '97 Camry's timing belt changed at 93K miles by a co-worker (who used to be a Toyota tech), the engine was running perfectly and there were no visible signs of wear on the removed belt. My understanding is this is typical if you don't procrastinate on this needed maintenance service.

    Your '97 Camry has a "non interference" engine, so if the belt breaks, the engine will quit immediately and you'll be stranded, but there will be no collateral damage (unless you get hit by the guy behind you). Cars with interference engines run the risk of bent valves and damaged pistons when the timing belt breaks -- lots of $$$ down the tubes.

    If your car is approaching 90K miles, and you cannot ascertain if the belt was ever replaced in the past, then it's time to do it now!

    Oh and BTW, I did have a timing belt break prematurely, on my former 1980 Volvo 240. There was no prior warning; the engine just died suddenly. Luckily we were on a city street in the right lane and had enough momentum to make a right turn and coast to a parking space on a quiet side street. This engine was non interference also, luckily.
  • I just had my 94 camry timing belt changed and now it has no power from a dead stop even thou it runs fine on the highway and idles smoothly. It ran fine before the new belt was installed what could be the cause of this? Any ideas would be apprieciated
  • kiawahkiawah Posts: 3,666
    Sounds like the timing is off a tooth or so. There are timing marks on the pulleys, and when you put the cogged belt back on you have to make sure the timing marks line up accurately.

    Who did the timing belt change?
