FAQ

Q: How do I verify that this 5i7578 sensor is compatible with my Caterpillar 320C engine?
A: To confirm compatibility, please check the part number on your existing sensor. It should match either 5i7578 or 297-9314. Additionally, verify your engine model (e.g., 320C) and the sensor’s thread size/location. If your current sensor has a different number, please contact us with your engine serial number for cross-verification.

Q: What is the installation procedure for this water temperature alarm sensor?
A: Installation is straightforward. First, drain coolant to a level below the sensor port. Disconnect the electrical connector and unscrew the old sensor. Apply a small amount of thread sealant (if not pre-applied) to the new sensor’s threads. Screw in by hand to avoid cross-threading, then tighten to the manufacturer’s specified torque (typically 15-20 Nm). Reconnect the wiring, refill coolant, and test the system by running the engine to check for leaks and proper alarm function.

Q: What should I do if the alarm triggers immediately after installation?
A: An immediate alarm usually indicates a wiring issue or a faulty sensor. First, check that the electrical connector is fully seated and clean. Ensure the wire harness is not shorted to ground. If the wiring is correct, the sensor may be defective. Please contact our support team for a warranty replacement. Also, verify that your engine is not actually overheating due to low coolant or a stuck thermostat.
