Parts for your 2020 Bmw X3-Thermostat housing

2020 BMW X3 Thermostat Housing

Based on BMW technical sources, the 2020 BMW X3 (G01) is fitted with a thermostat housing. The BMW ETK/parts catalogue (as mirrored by RealOEM) lists complete “thermostat with housing” assemblies for the X3’s B46/B48 2.0‑litre petrol (xDrive30i), B58 3.0‑litre petrol (M40i), and B47 diesel variants, confirming the part is present across the range. BMW TIS repair instructions also cover removal and replacement of the coolant thermostat for these engines, which verifies both fitment and serviceability on the 2020 model.

On this X3, the thermostat housing is a moulded composite unit that bolts to the engine and integrates the map‑controlled thermostat, coolant passages and quick‑connect hose ports. Its job is simple but critical: it meters coolant flow so the engine reaches and holds the right operating temperature. When cold, it keeps coolant in the block for a quicker warm‑up
