If you have noticed coolant puddles under your BMW or on the side of the engine block, these gaskets are the likely culprit. These gaskets seal the thermostat housing to the engine block. Over time, these seals can become brittle, causing them to crack and cause coolant leaks. Replace these seals whenever leaks occur or whenever the thermostat housing has to be separated from the engine block. Replaces BMW # 11538588942
