Hold engine temperature in check with the SKP Engine Coolant Thermostat Housing Assembly / Thermostat Housing (MPN SK902813AL), a direct-fit replacement for a long list of BMW models. It sits at the engine block and channels coolant through the cooling system, providing the housing for the thermostat that regulates flow between the engine and radiator so the engine reaches and holds normal operating temperature. Fitment spans the 1999-2000 BMW 328I and 528I, 1999-2001 BMW 323I, 1999-2002 BMW Z3, 2000 BMW 323CI and 328CI, 2001-2005 BMW 320I, 325XI, 330I, 330XI, 525I and 530I, 2001-2006 BMW 325CI, 325I, 330CI and X5, 2003-2005 BMW Z4 and 2004-2006 BMW X3 — see the Buyer's Guide tab for the full list.
- Regulates coolant temperature: houses the thermostat that controls coolant flow between the engine and radiator.
- Directs coolant flow: supplies the passage and connection points for coolant moving through the cooling system.
- Mounts at the engine block: replaces the original thermostat housing location on the listed BMW applications.
Signs the original housing may need replacing include coolant seepage around the housing, overheating, or erratic temperature-gauge readings. Diagnose the cause first; if a cracked or failed housing is the culprit, this SKP unit replaces it.
