    Hey Yall

    So I got a small squeak when the engine is cold and first turned on (squeak goes away in few minutes). So seeing as my truck has 130k, figured I may as well change the idler pulleys along with the belt. The tensioner pulley & assembly I will hold off on- until it gives me an issue (seeing as its a pain to remove).

    I' am having trouble figuring out which idler pulleys I need.
    Longo toyota site diagram shows 2 pulleys are needed ( and same part numbers? 16603-0P030)

    But some diagrams show three idler pulleys ( 2 identical, 1 different), but no Toyota parts website is clear to me, I see 2 part numbers : 16604-31020 & 16603-0P030.

    Can anyone help guide and confirm what pulleys are needed?
