2000 Saab 9-3 Coolant Temperature Sensors

Carquest Premium coolant temperature sensors and switches are designed to perform in harsh engine environments and meet or exceed original equipment (O.E.) specifications. Built by manufacturers that meet IATF 16949 certified framework, an internationally recognized proof of quality in the automotive industry, Carquest Premium coolant temperature sensors and switches undergo extensive validation testing to ensure long-lasting performance and reliability. Carquest Premium coolant temperature sensors and switches are part of our Carquest Vehicle Solutions, which is a full line of engine management and electronics products that help control ignition, fuel delivery and emission systems. Carquest Vehicle Solutions are OE-quality parts designed, engineered and tested by world-class manufacturers to ensure a reliable and long-lasting repair.

Carquest Coolant Temperature Sensors provide accurate data to the PCM to ensure proper management of your vehicle’s fuel injection system, ignition and variable valve timing, transmission shifting, and more. Manufactured using the highest quality OEM approved materials for increased durability in even the most extreme temperatures. All Carquest Coolant Temperature Sensors are designed to meet or exceed OEM specifications at our ISO TS16949 manufacturing facilities.

The engine coolant temperature sender, not to be confused with the engine coolant temperature sensor, is located anywhere within the engine cooling system and contains a thermistor that changes in resistance value as the thermistors ambient temperature changes. The engine coolant temperature sender is fed 12 volts and is typically used in conjunction with a gauge in the instrument cluster to provide a visual representation of the engine coolant temperature condition.

The Engine Coolant Temperature Sensor determines the exact temperature of the engine coolant by sending an analog signal to the ECM to ensure proper air/fuel ratio along with proper operation of the cooling fans and temperature gauge. The Engine Coolant Temperature Sensor may be located on the cylinder head, engine block, thermostat housing or intake manifold. Reasons for replacement include, check engine light illumination, erratic or no temperature gauge operation, erratic or no cooling fan operation, and engine overheating.

Rein Automotive OE temperature sensors are made to factory specifications ensuring proper fit, form and function. The temperature sensor is used to report exhaust temperatures to the vehicle’s ECU. The vehicle uses this information to control engine and emission paramaters. Rein temperature sensors include a vehicle specific connector that fits directly into the factory plug. Our quality temperature sensors aim to provide the professional repair technician and vehicle owner the peace of mind and trust that is expected from an OE component.
