Original BMW Engine Oil Thermostat Housing with Thermostat for N54 and N55 BMW 1, 3, 5, 6, and 7 Series, X1, and Z4 (2007–2016)

On N54 and N55 engines, the Original BMW engine oil thermostat 11-42-7-573-212 is the thermostat housing with thermostat that controls oil flow to the engine oil cooler in 2007–2016 BMW 1, 3, 5, 6, and 7 Series, X1, and Z4 models. An oil thermostat keeps oil away from the cooler while the engine warms up, then opens to send oil through the cooler once it reaches temperature. BMW supplies the thermostat already fitted in its housing, so the assembly installs as one piece. BMW's part data marks it 110 CEL, a 110 °C rating. Production started in April 2007, and the part is made in Germany.

Original BMW Parts carry a 24-month parts warranty.

The housing does not come with a gasket. Order the engine oil cooler gasket, 11-42-8-637-820, along with it. In BMW's oil filter and lubrication diagram, the thermostat sits beside the oil filter housing 11-42-8-642-289, the filter housing cover 11-42-7-525-334, the thermostat housing bolt 11-42-7-542-983, the thermostat housing plug 11-61-7-568-552, and the oil pressure switch 12-61-8-611-273. This number supersedes 11-42-7-564-892. BMW rates the change as exchangeable retrospectively, so it also fits cars built with the earlier part.
