Get an accurate coolant reading with the Standard Ignition Engine Coolant Temperature Sensor TX28, a direct-fit replacement for a range of late-1980s Chrysler-family applications including the 1985-1990 Jeep Cherokee, Comanche, Wagoneer and Wrangler, the 1988-1989 Eagle Premier, and the 1986-1987 Renault Alliance and Encore. It installs with a bolt-on attachment and uses a tight-tolerance thermistor to send an engine coolant temperature signal to the control module, which manages fuel delivery and cooling.
- Factory calibrated: set to the OE temperature set point for dependable electrical contact.
- 100% factory tested: every sensor is checked for out-of-the-box reliability.
- Tight-tolerance thermistor: specified response values help keep the temperature measurement accurate.
- Build & connection: brass body with a bolt-on attachment and an oval plug-in connector carrying two female bullet terminals; 12V.
As the coolant warms and cools, the thermistor's resistance changes, giving the control module a real-time reading it uses to adjust the air-fuel ratio and cooling. Signs this sensor may need replacing include an erratic or inaccurate temperature gauge, hard cold starts, or a coolant-temperature-related trouble code — diagnose the cause first, and if a failed coolant temperature sensor is the cause, this unit replaces it.
