Q:
I´m replacing the Pulley, Sub Assy. Idler No. 2, Item 16604-31020; do I need both 2ea Plate, Idler Pulley Cover, Item 16649-31020, and 2ea Plate, Idler Pulley Cover No. 2, Item 16659-31011? Posted by Customer: 2009 Lexus RX330 or RX350
A:
#1) It is not necessary to change the Plate covers, but if they have never been replaced before, I would recommend replacing them when you replace the pulleys. #2) The strainer does not come with the O ring gasket, it is sold separately.
