WP and Alternator OEM too

never had even 1 check engine lite in 15 years.

bought the tool to check the codes, but never have had to use it.

never had an overheat. never had a coolant leak.
I do change the coolant every 5 to 7 years with the best stuff.

Hope you didn't just Jinx yourself lol

You'll never have to replace your timing belt, because the v6 has a timing chain

I was in a similar situation as you. Just picked up my '03 this summer w/ ~275k miles. I didn't know how long it had been since the timing belt had been changed when I bought it, but everything else seemed to be well-maintained. I put about 1k more miles on it over the summer and it drove like a dream.

Took it to a local mechanic last month that has always done me right, and he figured out it was last changed at 90k miles! He said he'd charge me ~$750 to replace it, so I pulled the trigger on it. I figure it probably would have lasted awhile longer, but...you never know!

tl;dr - 176k miles

200,000 miles and 21 years on the original timing belt.
It is getting changed this May.
Running like a champ for the most part. I don't want to chance the destruction of my motor.
There is no plate/sticker to indicate next change, there never has been.
The Toyota dealership I usually go to says that its original to the car.

If you have the owner's service manual you'll see it's a 90,000 mile service. If your belt breaks you'll have a very large paperweight because the V8 is an interference engine, meaning the valves extend into the cylinder. A belt break means the pistons will be hammering those valves. :-(

Wow, some real chance takers here. Never let a belt go over 100k.

$1000 belt change or $45,000+ new 4Runner. I'll swap the belt.

I got the car at 180 something thousand miles, and have been struggling for money until recently. Toyota can build a good belt. I cant stress this enough though DONT LET IT GET THIS BAD.
there are major oil leaks from the timing cover and I dont think she's going to live much longer. Glad I'm changing it soon

bought it with 268k and no tag or service history of it being done. Worked at Toyota/Lexus dealer at the time. Tech said it was original but didn't look bad. Explained the angles for the routing on the 2uz make them less likely to fail compared to other engines. I had a customer there with 346k on 03 v8 with original belt. Engine failure was caused by his daughter letting a radiator leak go without keeping coolant in it.
