{"product_id":"engine-coolant-thermostat-assembly-3","title":"Engine Coolant Thermostat Assembly","description":"The Borg Warner 11537549476 is an engine coolant thermostat assembly designed to regulate the thermal performance of compatible BMW engines. This OE-quality component ensures that your engine reaches its optimal operating temperature quickly and maintains it consistently. Thermostats play a crucial role in engine health; a failure in the open position can lead to a rich fuel mixture, poor fuel economy, and potential catalytic converter damage, while failure in the closed position can cause severe overheating and catastrophic engine damage.\n\nThis thermostat assembly is manufactured by Mahle Behr, a reputable supplier of automotive engine components, and is equivalent to OE part numbers 11537549476, 11537536655, and 11537544788. For optimal installation, it is recommended to align the 'jiggle pin' bleed valve at the 12 o'clock position when possible.\n\nThe Borg Warner 11537549476 thermostat is compatible with a range of BMW models including the 1 Series M, 128i, 135i, 325i, 325xi, 328i, 330i, 330xi, 525i, 525xi, 530i, 530xi, and various Z4 models, typically from the mid-2000s through the early 2010s, primarily featuring the N51, N52, and N54 engines.
