Rein builds these thermostat inserts with OE-level materials and calibrated response characteristics to match the original cooling system behavior, helping maintain stable engine operating temperature. This part cross-references BMW 11537511083 for the same application. The CTN0076 part number is a practical reference when sourcing an engine coolant thermostat for BMW 318i, 325i, 328i, 528i, Z3, and M3 applications.\u003c\/p\u003e\u003ch2\u003eCompatible With BMW Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFits 1998-1999 BMW 323i, N\/A\u003c\/li\u003e\n\u003cli\u003eFits 1998-1999 BMW 323is, N\/A\u003c\/li\u003e\n\u003cli\u003eFits 1997-1999 BMW 328i, N\/A\u003c\/li\u003e\n\u003cli\u003eFits 1996-1999 BMW 328is, N\/A, 92c\u003c\/li\u003e\n\u003cli\u003eFits 1997-1998 BMW 528i, N\/A\u003c\/li\u003e\n\u003cli\u003eFits 1997-1998 BMW Z3, N\/A\u003c\/li\u003e\n\u003cli\u003eFits 1996 BMW 328i, N\/A, 92c\u003c\/li\u003e\n\u003cli\u003eFits 1992-1995 BMW 318i, N\/A\u003c\/li\u003e\n\u003cli\u003eFits 1992-1995 BMW 318is, N\/A\u003c\/li\u003e\n\u003cli\u003eFits 1995 BMW 318ti, N\/A\u003c\/li\u003e\n\u003cli\u003eFits 1992-1995 BMW 320i, N\/A, 92c\u003c\/li\u003e\n\u003cli\u003eFits 1992-1995 BMW 325i, N\/A, 92c\u003c\/li\u003e\n\u003cli\u003eFits 1992-1995 BMW 325is, N\/A, 92c\u003c\/li\u003e\n\u003cli\u003eFits 1991-1995 BMW 525i, N\/A, 92c\u003c\/li\u003e\n\u003cli\u003eFits 1994-1995 BMW M3, N\/A, 92c\u003c\/li\u003e\n\u003cli\u003eFits 1993 BMW 525iT, N\/A, 92c\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEngine running too cool or too warm due to thermostat wear\u003c\/li\u003e\n\u003cli\u003eDelayed coolant flow control during warm-up\u003c\/li\u003e\n\u003cli\u003eTemperature fluctuation in the cooling system\u003c\/li\u003e\n\u003cli\u003eCooling system service on BMW models using a 92°C thermostat\u003c\/li\u003e\n\u003cli\u003eReplacement of a worn or sticking thermostat insert\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the thermostat housing style and the required opening temperature before installation.
