Does the belt tensioner look like a chain tensioner on a deraileur fixed on a mountain bike? If so, that means that you can physically pull back the tensioner and loosen the belt? I've pulled on the belt myself and that thing is very difficult to pull/stretch. The belt doesn't look like it has much "freeplay" or "stretch factor" sorta speak. A mechanic told me that squeaking belts can happen if the belt stretches too much over time, eventhough, cracks are nonexistent. Is he telling the truth?How often would depend on the driving conditions - some people can get anywhere from a lowside of 15K miles to as much as 100K. Usually you can tell by just looking at the belt. Little cracks in it are normal - but an excessive amount of cracks, missing chunks of rubber ribbing, or any portion of the cord backing showing itself - mean you need to change it out. I would also check on the condition of the belt tensioner as well - any play/slop or tightness/friction in the pulley assembly means you have to atleast change the pulley. Most mechanics will NOT check this - they just want to swap parts off the car.
For mechanics to do this - most will charge 30 minutes of "book time" - runs anywhere from $30-$75 for just labor + parts. Belt usually runs about $30 - the OEM piece is made by Bando, very good quality. Others are Gates, Dayco, and Goodyear - all very good ones as well. As for a DIY job - very easy to do. If you can change the oil - you can do this job. This has been mentioned on this forum many times before - biggest hurdle is remembering how the belt runs over or under the pulleys - many times there is a diagram on a placard under the hood, but taking a picture or making a diagram first is highly recommended.
You have way over 100k on your car right? If I were you, I'd replace that sucker ASAP. If it breaks, you'll be sorry. Sure it isn't the timing chain, but it runs your PS, PB, ALT, AC and WP. You won't go very far with no coolant circulating through your engine block, and you'll have a hard time stopping and steering if you don't have PS and PB boost. Also, your battery will bite the dust, and need replacement if you run the car solely from the battery for very long.How often should I replace my serpentine belt? How much should I expect it to cost if I have a mechanic do it? Is it an easy DIY job?
Right, 200k. But I highly doubt its the original belt because there are no cracks or anything. I know its at least, at the very least, 50k. I say that because my 'rents gave the car to me 50k miles agoYou have way over 100k on your car right? If I were you, I'd replace that sucker ASAP. If it breaks, you'll be sorry.

Your car has a timing chain that should last until the car is a rustbucket. Some new Japanese cars and almost all of the ones built before the late 1990s had timing belts. They had to be replaced anywhere from every 30k to every 90k. If you didn't replace them you were risking it big, because if it broke while you were driving, you might ruin your engine. At bare minium, you'd be stranded.I was told my belt (timing?) needed to be replaced.
Guys the serp belt should last @45k to 60k miles and thats under good driving paractices.I know...I'd fix it if I had even a slightest clue...
I don't own an owner's manual, I can't seem to get my hands on a Chilton's or hayne's in my model year... (at the library)
I can't even find them in the bookstore...
I don't even know where to begin in my google search
MT,If you are gonna do it yourself dont be cheap because it WILL HURT when you get bitten for doing it with the wrong part.Buy the Toyota part and get what you paid for.after removing the belt pump the tensoiner between loose and tight 3 times and if there is very little resistance when compressing the tensioner the replace it. and oyu will need a jack and other thing to unbolt the motor mount and raise the engine to get the tensioner bolt out.then after pumping the tensioner 3 times reinstall the belt. You have to pump the tensioner to remove trapped air and extend the life.
Also if you see an oily residue on the tensioner body(looks like a shock) then replace it as well.
If the belt is worn - replace it, if it looks fine - try adjusting the tension on it.Yeah, I have tried belt dressing in the past and I dont like to use it. I believe that it softens the rubber in the belt and causes it to deteriorate faster than it should.
I'll try a new belt since the shock on the tensioner looks like it is in perfect condition.
How would the tension be adjusted? Isnt the tension determined by the "shock" on the tensioner apparatus?If the belt is worn - replace it, if it looks fine - try adjusting the tension on it.
