Searching for Allen bolt size - timing belt idler pulley

Did a search for the above and got zero results. Timing belt replacement instructions reference the “large Allen bolt”.

It must be this Allen bolt on the timing belt tensioner pulley assembly. A new assembly is included in the Aisin TB/WP kit.

I replaced my TB a couple of months ago, and IIRC it is a 10mm hex wrench.

I tried to post pictures earlier but they wouldn’t load...here is thread I created when I did the TB job on my 2002.

10mm Allen sounds correct...just pick up a set at Harbor Frieght Tools. 3/8 drive socket Allen.
