Frequently Asked Questions
Q: What vehicles is the Engine Coolant Temperature Sensor 55591002 compatible with?
A: This coolant temperature sensor uses OEM reference number 55591002 and cross-references including A0005425118, 55591401, 55353807, 12641073, and 12636534, among others. We strongly recommend comparing the part number and connector style with the sensor you are replacing to confirm compatibility with your specific make, model, and year before installation.
Q: Is this sensor a direct plug-and-play replacement?
A: Yes. This engine coolant temperature sensor is engineered as a direct OEM replacement, featuring a matching right-angle elbow connector and cylindrical metal probe. No wiring modifications are needed — simply disconnect the old sensor, install this unit, and reconnect the harness connector.
Q: What does the integrated seal do?
A: The integrated seal forms a watertight barrier around the sensor's installation point, preventing coolant from leaking out of the engine block or housing where the sensor is threaded in. This helps maintain proper coolant system pressure and keeps the engine bay clean.
Q: Can I install this sensor myself?
A: Many vehicle owners with basic mechanical experience can install a coolant temperature sensor. However, because the procedure involves your vehicle's cooling system, it is recommended to allow the engine to cool completely before starting, safely drain any necessary coolant, and consult your vehicle's service manual for torque specifications. If in doubt, have the sensor installed by a qualified automotive technician.
