Purge trapped air from your BMW's cooling system with the Dorman coolant air bleeder screw (P/N 902-404). This engine coolant bleeder screw threads into the bleed port to vent air pockets during a coolant fill or bleed procedure, and it matches the original screw for fit and function. It's a direct-fit replacement across a wide range of BMW models, including the 2008-2013 128I [L6-3.0L], 2012-2016 328I [L4-2.0L], 2007-2015 335I [L6-3.0L], and 2016-2024 330I [L4-2.0L] — see the Buyer's Guide tab for the full list of 176 applications.
