What the manual does not print
The 2018 Toyota Sienna owner's manual does not list wipers, battery and filters sizes; for the battery, read the label on the battery fitted to the car, then check the size against the BCI group chart; for wipers, measure each blade end to end and buy the nearest whole-inch size.
Buying the parts for a 2018 Sienna
- Headlight bulbs: the D4S low beam and the 9005 high beam are halogen capsules on trims that have them; buy them in pairs so both sides match in colour and output.
- Small bulbs: this manual names 13 replaceable bulb positions. Wedge bulbs such as W5W and 194 differ from twist-socket bulbs such as 7443 or 3157, so match the full number, including suffixes like NA (amber).
- Oil: ILSAC GF-5 SAE 0W-20. Use the grade printed for your engine if the manual lists more than one.
Check it on your car
