It's a nice day in NorCal today, I installed a new dynamic belt tensioner and
a new Dayco Poly-Cog (5060895 - 89.5" belt. The original set are ~ 3.5-years old (~ 40K miles). Remove the idler plate using a 8mm allen head socket.

While the upper cowl assembly (only on a Sienna) is removed, I installed the (Tacoma) TRD boost gauge that I had for a while.

I also installed a used 100-amp alternator that came from (32Kmiles) 01 Highlander (1MZFE engine).
