Is there a way to tell if the timing belt has been changed before? (V6)

[First 4Runner]

I have a 2007 Sport 2WD (V6) with 155K miles which I bought used and have no history on it. I was wondering how often a timing belt needs to be changed and if there is a way to tell if it has been done or if the car will give you any indication that it needs to be done.

Kind regards

V6’s have timing chains! You should be good to go for a long time!

Even still. You can always go to your local toyota dealer and ask them to pull the service records on it to see if/when it was done. All timing belt/chains are recommended to be done every 90-100k miles. If the dealer has absolutely no information for you, I would recommend doing it. It may have a timing chain cover you can pop off for a visual inspection, but I don't remember, to be honest.

You can look the records up online as well.

What’s the source on all chains needing replacement at 100K?

Yes, I did that. Setup an account on Toyota and it let me see the service history but nothing about a timing chain.

I thought timing chains were good to go for a very very long time, unlike belts.

I cant find anything in the actual Toyota FSM. The "recommended" interval is 90-100k. There are people who's stuff breaks or stretches at 100k, there's people who's stuff never breaks until 200k or more. It's all on the owner and what they want to do.

I think it is just belts that need replaced at 100k-ish. I had a 1988 4Runner and the timing chain was original when we parted ways at 305k miles. Fresh, clean oil is the key to making this last a long time.

What [MENTION=266619]thennen[/MENTION] said is where I was going - pretty sure the 90-100K interval is for belts. Just seems otherwise that there would be a bunch of threads here about servicing/changing the V6 chain.

Of course, I've been wrong before.

Did some farting around on the tacomaworld forum. Here is what I found:

https://www.tacomaworld.com/threads...g-chain-on-all-toyotas-from-toyota-com.19496/

belts are recommended at every 90k. Timing chains are "supposed" to last the life of the engine. 250k plus.....however there are variables...how you drive, maintenance, etc...

My brother maintains his FJ religiously and had to replace the timing chains at 180k due to stretching. He's a mechanic and said he never wants to do that crap again because of all the stuff you have to take off.

Now you're on the correct track on the diffrence between timing belts and timing chains replacement

aww cute thread

Yep. No thanks.

 

[AuSeeker]

Yep. No thanks.

So you're saying "no thanks" to learning new info???

To each their own I guess.

Not at all!! I was saying no thanks to having to deal with timing chains!

What model year was your brother's FJ Cruiser? While there are known issues with poor oil change maintenance leading to timing chain elongation on these engines, this is the first case I've seen where good maintenance practices were followed.

I think its an 09. Not for sure, however.

That would be a unique case, can you find out for sure?

The '07 FJ and 4Runner, with a single 2008, have made up all of the stretched timing chain cases I found while researching my problem. If this happened on a well-maintained 2009 it would counter the thinking on a bad batch of timing chains as the root cause.

Very interested to know the year of his FJ if you don't mind finding out...
