Standard Ignition Engine Oil Temperature Switch P/N:TS-437
Give your engine's oil temperature circuit a calibrated signal with the Standard Ignition switch TS-522, an Engine Oil Temperature Switch built for the 1988-1990 BMW M3. It is a direct-fit replacement for this listed application. See the Buyer's Guide tab for engine details.
An engine oil temperature switch opens or closes an electrical circuit when engine oil reaches a set temperature, so the vehicle's circuit can respond to changing oil temperature. Standard Ignition factory-calibrates each TS-522 to its set point and tests it to confirm that it actuates.
Signs this part may need replacing: an erratic or missing signal in the circuit the switch feeds, or oil seeping around the switch body. Wiring faults and other components can cause similar symptoms, so diagnose the circuit before replacing the switch.
