Timing belt OEM Toyota or DAYCO

Built Toyota tough. 20+ years out of a factory belt.

I bought my 1st Toyota T100 3.4l it had 198k miles, when I removed upper timing cover, the water pump pulley FELL out, the belt was about 1/2 as wide as new. Truck ran fine!

Dayco is an OE manufacture for many manufacturers, it's a pretty solid belt. Quick answer is yes you should get it changed ASAP, I've seen a lot worse belts than this one and they drove to the dealership just fine.

My in-laws Toyota is at 230k original timing belt miles.

When I had mine done a year ago, independent shops were quoting $950-$1,100 while a Toyota dealer quoted $1,200.

I bought my timing belt/water pump off amazon. It’s a Dayco product (part number WP215K1B) and so far I’m happy with it. Obviously I won’t know if it’s some trash until a little further down the road, but I’m 20k miles into it and so far no trouble.

I had about 205,000 miles on my avalon when i traded it in... that had the original timing belt.

I have a 2002 V6. I bought it new and didn't change the original timing belt until 2015 at 181,613 miles. I didn't have a particular REASON to change it then. I just decided I wanted peace of mine that I wouldn't get stranded somewhere. My old one was a little cracked, but who knows how much longer it would've lasted.
