Overview

The URO Engine Coolant Thermostat Housing is an aluminum replacement designed to replace the failure-prone OE plastic housing on BMW M50 and M52 engines. This component houses the thermostat, which regulates coolant flow to and from the engine. It connects the engine to the radiator via hoses and helps control the engine's operating temperature. This housing comes with a thermostat housing gasket and is manufactured in Taiwan.
Show original supplier description
The URO Parts thermostat housing is a durable aluminum replacement designed to address the known failure points of the original plastic thermostat covers found on M50 and M52 BMW engines. These plastic components are prone to cracking over time due to repeated exposure to hot coolant, which can result in significant coolant leaks and potentially cause the engine to overheat. By upgrading to this cast aluminum housing, you eliminate the risk of plastic housing cracks, providing a more robust and reliable solution for your vehicle's cooling system. This part is manufactured from aluminum and includes a thermostat housing gasket, ensuring a proper seal. This thermostat housing is compatible with a range of BMW models including the E34 525i, various E36 323i, 325i, 325is, 328i, and 328is models, as well as certain Z3 models. Specific fitment details, such as engine variants (M50, M52, S50, S52) and production date limitations (e.g., Z3 2.8L models up to 09/1998), should be verified using the vehicle selector to ensure compatibility.
