Belt Tensioner Pulley P/N?

Hi, I cannot seem to find the individual P/N for the tensioner pulley on the 5th gen. I can only find the belt tensioner assembly that includes with the pulley under P/N 16620-31051. Can this pulley be purchased separately? Thanks.

Edit: I found this on Amazon, says it's manufactured by Febest. Other forums say to stay away from this brand:

Did this work? I need a tensioner pulley and can't find anything on it. All I can find is the whole assembly.

 

Is this it?

Seller is called "AutoProAmerica" and seems to be legit. Theyre touted by Ford and Jeep Chrysler mechanics as good aftermarket OEM equivalent sellers so you could try it? Didnt see any input from Toyota folks. Otherwise I didnt see anything outside of the whole tensioner assembly like you mention

 

I just ordered this one. It says it is a tensioner pulley. https://www.ebay.com/itm/153096388064

 

Any update? Did it work?

 

I installed the AutoProAmerica pulley in 2023 and it's still working fine: https://www.ebay.com/itm/224202113145

Note the included bolt is too short, so I simply reused the factory bolt. Note the tensioner pulley bolt is LH thread.

The lower idler pulley also fits on the tensioner.

 

Perfect thanks. Were the bolts hard to remove?

 

^Lower idler required double-wrench method due to crowding by the oil cooler. The tensioner pulley gave no trouble: https://www.4runners.com/posts/438971

Put an allen key in the tensioner hold-open hole.
