{"product_id":"bmw-thermostat-o-ring","title":"Original BMW Thermostat Housing O-Ring for BMW E28 M5 and E24 M6 (1987–1988)","description":"\u003cp\u003eFor the S38 six-cylinder in the 1988 BMW E28 M5 and the 1987–1988 E24 M6, Original BMW O-ring 07-11-9-906-322 seals the engine coolant thermostat housing. It measures 65 x 3.55 mm and weighs 3 g. BMW names it simply an O-ring, and this number entered production in March 2008 as the current replacement for the thermostat housing seal on these cars. It is sold one O-ring per order.\u003c\/p\u003e\u003cp\u003eOriginal BMW Parts carry a 24-month parts warranty.\u003c\/p\u003e\u003cp\u003eA thermostat housing O-ring sits between the housing and its mating surface and keeps coolant from weeping past the joint as the system heats and pressurizes. This number replaced the earlier BMW part 07-11-1-304-202, and BMW rates the change as exchangeable retrospectively, so it fits engines built with the older seal. BMW's parts data ties it to the S38 engine family, which covers the E28 M5, the E24 M6, and the M635CSi. The same seal also appears outside the car range, on the M1 and on several BMW motorcycles, including the K 1600 and S 1000 XR models. \u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: BMW (Original BMW Parts)\u003c\/li\u003e\n\u003cli\u003ePart number: 07-11-9-906-322\u003c\/li\u003e\n\u003cli\u003eBMW name: O-ring\u003c\/li\u003e\n\u003cli\u003ePosition: engine coolant thermostat housing\u003c\/li\u003e\n\u003cli\u003eSize: 65 x 3.55 mm\u003c\/li\u003e\n\u003cli\u003eWeight: 3 g (0.11 oz)\u003c\/li\u003e\n\u003cli\u003eProduction start: March 2008\u003c\/li\u003e\n\u003cli\u003eReplaces: 07-11-1-304-202\u003c\/li\u003e\n\u003cli\u003eSold as: single O-ring\u003c\/li\u003e\n\u003cli\u003eWarranty: 24 months\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCommon Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eDoes this replace the older thermostat seal number?\u003c\/strong\u003e\u003cbr\u003eYes.
