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.
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.
