Coolant Reservoir Cap for Subaru Forester Impreza WRX 45153AA000

Key features

• Verify your expansion tank neck diameter matches your existing cap before ordering. This is a two-way expansion tank cap (pressure release and vacuum recovery), NOT a radiator cap. Do not install on the radiator.
• Replaces OEM part numbers: 45153-AA000, 45153-AA010, 45642-KG000, SU003-01187, 16471-23030. Dorman equivalent: 54247. This is an aftermarket coolant expansion tank cap, not a genuine part.
• Compatible with Subaru: WRX 2002-2026, WRX STI 2004-2021, Forester 1998-2025, Impreza 1993-2025, Crosstrek 2013-2025, BRZ 2013-2025, Tribeca 2006-2014, Baja 2003-2006.
• Compatible with Toyota: GR86 2022-2025, 86 2017-2020. Scion: FR-S 2013-2016. Also fits Subaru Legacy 1990-2004 and Outback 1996-2004 (petrol engines only).
• Sold as a single cap. This fits petrol engines; the EE20 boxer diesel needs a different overflow nipple angle. Match the two-way valve and thread against your existing antifreeze reservoir cap before ordering to avoid the one-way radiator cap.
