Default Inspecting the timing belt ??

After hearing conflicting advice about replacing the timing belt, I
called Toyota's customer service center. They told me that, since I
was using schedule B (easy driving), the timing belt should be
inspected at 60,000 miles (or 72 months) and every 6 months after. It
should be replaced only if it shows wear. So my question is, How do I
inspect the timing belt?

If it's hard to inspect the timing belt, can I get an idea of its
condition by looking at the fan belt? (If they're made of the same
material, would they wear at about the same rate?)

The background: 1990 Camry 4-cylinder, 67,000 miles. The owner's
manual says to replace the timing belt at 60,000 miles for schedule A
(and only if driven frequently at low speed or idling a lot). For
schedule B, the timing belt isn't mentioned. But I've heard many
people say it should be replaced, some say at 60K, some at 75K, some
at 90K.

Well I replaced the timing belt on my wifes 98 at 68,000 and you could
not tell it from the brand new one. Not even a craze in the rubber. It
was perfect. And thats after many miles of her hot rodding around the
country side in Alabama where it gets pretty darn hot. Lots of fast
stop and go. I think they just want to ensure belt sales are kept at a
premium.

In my lifetime, I've had two timing belts fail. In both cases the failed
belt looked good except for the obvious damage (in one case it broke in
two, in the other several teeth were missing in one area). I don't
believe you can reasonably determine the condition of the belt my
looking at it on the vehicle. You might be able to determine it needs
replacing if it looks especially bad, but I can't see that a good
looking belt is a gaurantee that it is still good. As long as the faiure
of the belt doesn't wreck the engine, then letting it go is not that bad
(if you don't mind the inconvenience of having the vehicle towed).

Interesting,
My 1995 CAMRY 2.2ltr 64K miles is booked in next
Tuesday
to have the belt replaced.

Cost here at TOYOTA dealer is £157.00 that's $298.
The other local TOYOTA dealer quoted £240 that's $456.
For the same job.

Out of interest what's the going rate in USA.

I used to run TOYOTA MR2s...I had reason to check up with Toyota Technical
about the belt replacement on that. And was told it was a "fit and forget"
item.

It that because of different material or what.? Just wondered.

Have a nice day.

Johnny UK.

Ed: An observation I've made: Take a well used, high mileage belt
and drop it on the concrete so that it lands on one contiguous edge.
The sound it makes is a hard, sharp "clack." Do the same with a new
belt and you get a dulled "thud." I agree with you that
"work-hardening" is not visible.

Your belt is 14 years old -- its rubber based so is probably dried out from
age and engine heat regardless of mileage. Replace it if you are planning a
trip of any great lenth - let it go if you don't mind being stranded and
having to walk or have it towed.

$197 for all that? Sheesh, my old 4 cyl Honda's belt cost more than
that -- plus labour.

I have a 6 cyl Camry now ('99) with 70K on it, I think it's rated for
90K before changing on the 6 cyl. Is it true that the 6 cyl is a
non-interference engine? That's what I was told (as opposed to my '94
Maxima), if so, I don't mind being towed to the dealer or wherever
when it breaks as I hardly ever drive out of the city. That's what the
auto club is for.

You got 14 years on that belt!
I would change it and all the
rubber seals on that side of the
engine while the timing belt is off.
A check of the water pump is in order
as well as any oil leaks from the oil
pump shaft seal and the seal from
the block to the oil pump.
Your other belts are 14 years old
I would change them too.
All this is cheap insurance so you
dont get stranded..

The last time I saw a coupon for timing belt, it was like USD $120. So
$197 (I assume US dollars) is reasonable. The Brits are paying twice
what we are paying!

If you need water pump and idlers, then the price can go way up.
