    Thank you all so much for the input, especially Mr. BrokRench. You all gave me the answer I already knew, I just didn't want to hear it. I just hate having to spend so much money, but it is cheaper than a new vehicle. I love my 1999 4-Runner, it has been so reliable and it still looks brand new to me! Runs like a charm too. Okay now one last question, would you have the Toyota dealer do the belt job or a local mechanic that I use regularly do it? The Toyota dealer would charge $370.95 to do it. Should I do the water pump too? Thanks to everyone, Suzanne

The timing belt is an essential part, if it goes you are calling for a tow. I encourage you to have the belt replaced before this happens. While I've some belts still going with 200K on them (some people don't have the money, don't care, or don't have a clue) do you want to take the chance of being stranded. (don't you usually have someplace you need to be when this happens? and it's raining cats and dogs?) And if it's an interference motor as some have mentioned, the consequences are very expensive. But it's your vehicle, your call.

    Your favorite mechanic should be just fine. I think I would leave the water pump as-is. It will probably hold until the next belt change. The pump will warn you by leaking slowly before it goes altogether, the belt offers no such warnings.
    You have a nice Toyota, and you seem to take good care of it. You'll probably still have it at 250,000 plus at this rate.
    Thanks for the rating.

Hello fosterfam3...This is a very qood question..and an excellent vehicle to address it to. I evaluate timing belts the same way i do tires. after mileage is reached...the possibilty of failure is more likely, and like a tire that blows out without warning, the same applies to the timing are stranded..With that being said, i will also bring to attention that the 99 and later model 4runners have one of the best timing belts you will find in a belt driven valve train. Compared to most other belts, it's huge. The change interval is 90k or 72 months, which was increased from the previous year of 60k. I have changed these belts that had over 120k on them that showed signs of wear, but weren't excessively worn to the near failure point. In my opinion..I would not be afraid to go to 120K with these timing belts....However, since you are planning on keeping the 4runner you might consider replacement in the near future. The inconvience of a breakdown, the cost of towing, the possibilty of other componet damage would supercede the cost of a new belt.. that would be your decision....
Hope this answers your question and you find it helpful...

    Hello Suzanne...and thank you kindly ma'am for the acknowledgement. The water pumps average about 130-150k so you should go ahead and replace it also. The 3.4 litre is a non interferance engine, meaning if the belt breaks the engine stops. In regards to dealer vs local mechanic doing the work....get 3 repair order estimates. Make a decesion on who you trust and feel comfortable with. Sometimes, cheaper is not always better or vice-versa. I have regular customers that won't let anybody else touch their vehicle for repairs, for some reason i seem to kinda bond with whatever i'm working on. lol The 99 4runner is a great vehicle, it won SUV of the year for the second time in 99, don't blame you fo r wanting to keep her. I will attach a picture of the belt so you can relate to what is being replaced. Note: all pulleys, idlers and related componets should be closely inspected and a condition report of same logged for reference. Hope your 4runner provides you with many more years of dependable service. Feel free to return to Fixya for more support anytime.
    Thank you and have a great weekend...Sam...aka: BrokRench

You need to find out if the engine you have in there is an interferance engine. If so you should do the belt job because if it brakes you will bend valves and this can be quite costly. If it is not an interferance engine but has a timing belt and not a chain, you only need to change it for peace of mind. If it brakes on you there is the inconvenience and you have to have it towed.

    $370 by a dealer is a very good price, however they will find a way to **** another $400 out of you.

    I will go with the guy you trust and have been using all along. I would also go with putting in a new water pump while they have it open.

YES you should
the timng belt should be replaced every 100,000 kms but i do them at 80,000 because the timing belt is the thing that lifts and drops the valves and when that breaks the valves hang and the piston comes up and WHACK go`s the piston straight into the valves and then you motor is totally stuffed

2003 Toyota 4 runner

Hi robrtsn,
As you forgot to say what the engine is in your 4-Runner....I'll give you the rule of thumb....if you have a timing chain in your engine, you'll need to check it only if it becomes noisy....If you have a timing belt, the manufactures recommend that it's replaced every one hundred thousand kilometers.....thats about sixty five thousand miles.... I believe that the later vehicles...(those with the electronic odometer fitted) have been extended to one hundred and fifty thousand, but to be on the safe side, I'd replace at one hundred thousand, especially with the number of sub standard parts that are available on the market these days....

Hope that's a help

Best regards Johngee10
