Why you should change your timing belt every 60k, a pic is worth a thousand words Options

[presure2]

here is a pic of a toyota 5sfe timing belt with ~100k on it..it came outta itchyb's old 5sfe.
this is the reason toyota recommends doing the timing belt every 60k.



good stuff, heh heh..

i inspected my 60k old belt at 120K on the dot, it can go a couple thousand more miles.

i twisted it back and forth and ran my fingernail over the back of it. the belt wasnt signifigantly glazed and i couldnt feel any cracks on the backside of it.

i wish i had a timing chain instead of a belt.

[Steevo]

Mine looked like that.

How much does a timing belt change cost (ballpark) on a 7a?

I'd do it for like $650.

Wow.

Maybe that's the going rate where you are; I have a Toyota Dealership in Milwaukee offer to change mine (5S) for 170 (parts and labor)... I'm sure you'd probably throw in a water pump, though.


Never wish for a timing chain. They can still fail (look at the problems Volkswagen has with their 1.8T). Plus timing chain engines are almost always interference, so when they do go, your engine is essentially done.

$170? I call BS

But yeah that's everything on the front of the engine, front main seal, water pump, belts, etc. I always recommend getting it all done at one while it's all apart anyway.

Maybe I'm not reading this right. You opened everything up just to inspect it and you didn't bother replacing it? You sure you're not talking about the serpentine belt? There's a huge difference. You can't see the timing belt from the outside. It's completely covered.

our cars dont have serpentine belts. We have different belts for everything. Alternator, AC, PS.

Hey Doc.




Have you seen alot of front seals go on the 7AFE's? or valve cover gaskets? I had my valve cover gasket replaced as it was leaking. He said he front seal looked OK and wasn't leaking at all.


And I see my water pump on the back side of the engine in the open? And changine it seems to be a simple job. Any reason that I should be worried at 100K + miles?

Anyone else have problems with the alternator belt squealing on 3-2 downshifts where you redline the engine? (RPM matched)

Dead serious, Doc! This is what I was told last winter. Call them up and ask how much theyd charge for a timing belt replacement on a 2.2L 94 Celica. I was calling all around the state out of sheer curiousity just to see what people were quoting, and I got anywhere from 170 to 300 dollars (the final guy I went with did it for 220, mainly because his shop was 100 yards downhill from me and I could push my lifeless car there without paying for a tow).


Andew Toyota, Milwaukee Wisconsin -- 1-888-229-1466 (be sure to get in touch with the service department) let me know what they say!

i pulled the side cover below the valve cover and inspected the timing belt.
toyota 1zzfe, 2zzfe are both using timing chains and have had very very few chain failures considering the large volumes of those engines worldwide.

you cant compare VW to a toyota when discussing reliabilty, thats like comparing a corolla to an evo and saying that toyotas are all slow.

A lot? No, not really. They generally start going bad after 100K, but usually they leak very little so it's not a big problem, it's just a good thing to replace while it's all apart. The valve cover gaskets seem to go bad more often, but are also much easier to replace, especially on a 7A. The water pump isn't hard to change either, and if it's not leaking, I would't worry about it. The squealing just sounds like you need to tighten up the belt a little.

You know, after I thought about it, I realized I was thinking 3SGTE. The 5S is easier to change since it only has one cam gear and it's easier to access. In fact, I've never done a timing belt on a 5S! LOL

[x_itchy_b_x]

HHAAHA thats awesome!! sweet man glad it didnt break on me lol.

[bufferdan]

I'll change mine when it breaks probably

[phonex98]

Now im no mechanic or anything, but if your timing belt breaks... isint that going to royaly screw up your piston timing and probably blow the whole engine ? Valves and pistons collide or something like that.

[Bitter]

7A-FE is non interference, its really hard to get pistons to meet valves.

[phonex98]

Oh, thanks for the info

[CelicaZR]

I know you've to change the timing belt every 100,000kms.
But is there a time limit.
I remember someone at toyota telling it 100,000km or 10 years, whichever
comes first. Is this true? cause by the looks of it my car will 10 years old before it reaches
100,000 kms

[6gsillyca]

does anyone know if 3's interference engines or not?

[presure2]

all 3 engines (7A 5S 3S) are all non interference

[6gsillyca]

Oops sorry, bad engrish in last post, if anyone was trying to decypher what it meant. Was asking if 3sgte is an interference engine or not. Manny cleared this up. Thanks

[Batman722]

well we got mine out this past weekend, the belt didn't break but there were some teeth missing

pics of the outside of the belt







and the inside of the belt where 11 teeth were missing - these "missing" teeth were at one time around the crank, but after 12 years and 140K miles, they were just sheered off. The crank would spin and not spin the belt and that = no go.



once again, 12 years, 140K miles. I was lucky because I was about 5 min away from my house and was able to have the car towed there for nothing and I happen to have some great friends to get this replaced.

[Ve1Ls1dEvolutioN]

wow i need to change mine....139,000 miles...original timing belts...what should i change besides the water pump?? what is the tensioner everyone is talking about?? does this have to be changed??

[hurley97]

you don't have to change the tensioner but its recommended while you're in there, if the bearings in that go it'll make noise and eventually break and not hold tension in the belt causing it to slip or come off completely... so yeah, just change it. for the ST there is one tensioner and for the GT there are two, they come in the timing belt component kit

any "how to change belts" here in the forum?? or can anyone give me some tips on how to change it on my own...would hate to go to the dealership and pay hundreds of dollars...
