Purge trapped air from your BMW's cooling system with the Dorman - OE Solutions Engine Coolant Bleeder Screw 902-404. This bleed screw threads into the cooling system's bleed port so air pockets can escape while you fill and burp the system, helping coolant circulate properly. It's a direct-fit replacement across a wide range of BMW models — including the 2008-2013 128I, 2012-2018 320I, and 2007-2015 335I — spanning L3-1.5L, L4-1.6L, L4-1.8L, L4-1.9L, L4-2.0L, L6-2.5L, L6-2.8L, L6-3.0L, L6-3.2L, V6-3.6L, V8-4.0L, V8-4.4L, V8-4.6L, V8-4.8L, V8-5.0L, V12-5.4L, and V12-6.6L engines; see the Buyer's Guide tab for the full list of 176 applications.
