105° C thermostat, includes housing and o-ring

The thermostat is a critical part of your BMW's cooling system. It controls the flow of coolant in the engine which controls the temperature of the engine. Thermostats typically fail in the open position which will cause the engine to never reach operating temperature and cold air will blow out of the heater. A thermostat stuck in the closed position will cause an overheating condition.

When replacing your BMW's thermostat you will need to replace coolant. For this application we recommend Genuine BMW coolant mixed 50/50 with distilled water.

I bought this for my friends BMW when his water pump failed. One of the screw holes cracked as he was tightening the bolt which scared him $#@!&less. He said if it starts leaking or if it just completely breaks he would/will send it back, but for right now he is just glad that his baby is running again!
