Timing Belt Maintenance

Just a question for you guys?, How many of you have changed the timing belt & serpentine belt before 100k?, I am coming up on 100k (currently 92,300k) and want to do this preventive maintenance and just wanted some feedback.
Thanks guys

 

Pretty sure the timing belt is a chain nowadays.

 

the 3rd gen has a timing chain, and the serpentine belt is a very simple job to change.

 

3rd Gen Tacos have timing chains, not belts. Maintenance should be done at factory-recommended intervals. In the case of the chain, it lasts the life of the engine or around 250,000 miles.

The serpentine belts should be done every 100k max in my opinion. Checked for damage/cracking regularly with oil change and be replaced if it starts making any noise.

 

I had to do my serpentine belt at 45k~. Squealing like a pig.

 

Since 2005, all Tacoma V6 have had a timing chain. 4-Cylinders have had timing chains since 1995. Here is a cool Toyota reference site on timing belts or chains.

thanks guys, good to know, i need to do my serpentine belt before 100k although i do inspect it and no cracks or noise yet.

 

may change the serpentine belt if i have time soon...thanks

 

so is it also good to replace the idler and tensioner pulleys?

 

If they are not making noise and they feel okay when you hand turn them with the belt off, I wouldn't worry about it. It really depends a lot on climate and if you're getting crud in them all the time or not. YMMV greatly on bearings.

 

Cool site. Thanks for posting.

 

Here’s some good information about the 3.5 V6.

 

Not to start an octane war, but interesting that the fuel octane is 91 or higher in this doc. So can I assume it was originally designed for that, and then detuned in the Tacomas?

 

I would change but I like to change things before they go bad and while you are in there you can change two pulleys for $110 so, why not? ToyotaPartsDeal.com $58 PN 16603-0P030 for Idler #1 and $51 PN 16604-31030 for Idler #2.
