11530139877 Thermostat Housing Assembly 11537509227 Review

The thermostat is a valve that goes between the engine and the radiator. It's purpose is to keep the engine working in a suitable temperature range. When the engine gets too hot, the thermostat opens up and lets the engine coolant flow through the radiator, where it cools off. When the engine is too cool, the thermostat closes and stops the coolant from flowing through the radiator, so the engine heats back up. This Thermostat Housing Fits for B-M-W 01 - 05 320i 2.2L, 2000 323Ci 2.5L, 99 - 2000 323i 2.5L E46, 98 - 99 323Ci Coupe 2.5L; 01, 06 325Ci 2.5L, 01 - 05 325i 2.5L, 01 - 05 325xi 2.5L, 2000 328Ci 2.8L, 99 - 2000 328i 2.8L, 1999 328Ci 2.8L, 01 - 06 330Ci 3.0L, 01 - 05 330i 3.0L, 01 - 05 330xi 3.0L, 01 - 05 525i 2.5L, 99 - 2000 528i 2.8L, 99 - 2000 528i 2.8L, 01 - 05 530i 3.0L, 04 - 06 X3 2.5L 3.0L, 01 - 06 X5 3.0L, 99 - 02 Z3 2.5L 3.0L, 03 - 05 Z4 2.5L 3.0L.
