Compatible Models
We do our best to list all compatible models. Although this may be the part you need, your exact model may not appear below.
Compatible equipment / model
- Generac mobile light towers using temperature sensor 16678 and a Mitsubishi L3E engine
- Generac mobile light towers using temperature sensor 16678 and a Mitsubishi S4L2 engine
- Magnum light towers using temperature sensor 16678 and a Mitsubishi L3E engine
- Magnum light towers using temperature sensor 16678 and a Mitsubishi S4L2 engine
Product Overview
A light tower that shuts down for temperature when the engine is not actually hot—or fails to warn while temperature climbs—needs the entire sensing circuit checked quickly. Confirm coolant level, actual temperature, wiring, connector, alarm module, thermostat, airflow, and water-pump operation before condemning the sensor.
This sender provides the temperature input used by the engine-protection or display circuit. The machine model and engine alone may not settle fitment, so compare 16678, the thread, terminal, body length, and temperature-switch arrangement.

- Restores engine-temperature monitoring on matching light towers
- Cross-references service number 16678
- Compatible with listed Mitsubishi L3E and S4L2 engine applications
- Supports repair of false alarms or missing temperature protection after testing
Replaces Part Numbers
- 16678

Compatibility Notice
Northline Parts does its best to list all known compatible models, but the correct part may fit an application not shown.
Production date, serial number, engine option, dimensions, connections, and previous repairs can change the part used within the same model. Compare the removed item and service information before purchase.
Frequently Asked Questions
Q: Will this sensor repair a light tower that is truly overheating? A: No. A clogged radiator, low coolant, bad thermostat, weak pump, belt problem, or airflow restriction must be repaired directly.
Q: Can a damaged wire create a false shutdown? A: Yes. An open, grounded, corroded, or rubbed wire can imitate a failed switch depending on the control design.
Q: What is the safest way to confirm this fits? A: Use the compatible list as a starting point, then compare the original reference number, dimensions, connections, mounting details, production date, and equipment or engine serial information.
Q: Who manufactures this service part? A: This is a new aftermarket part. The brand and model names identify the applications it is intended to service.
