I replaced the drive belt, tensioner, and idler pulley on the Tundra yesterday.
The tensioner was getting a bit noisy when cold so ordered a Gates kit on the 21st from Rockauto. The kit arrived in the 24th. Parts on the Gates kit don’t seem up to the OEM quality. Original parts are Dayco however when I ordered the Dayco kit wasn’t available. Ah well, I’m sure the Gates will be fine.
The truck has just over 200k on it now. The original tensioner and idler pulleys have no play in the bearings from what I could tell. Anyway, easy enough job and only took me a couple hours. Could likely do it in less than an hour now that I’ve done it once.
