The Honda 37765-ZA0-982 Engine Thermostat Switch (Nippon Thermostat) is a genuine OEM component designed for EV4010, EV6010, and EVD4010 RV generators. As a direct Honda OEM replacement, this switch is manufactured to the same specification as the original, ensuring the thermal protection circuit on your RV generator operates exactly as intended. Confirm your unit's serial number against the fitment table before ordering, as Honda supersedes parts at specific serial breaks — part number 37765-ZA0-982 must match your generator's production range.
Key Features
- Genuine Honda OEM Quality — sourced directly from Honda, this switch carries the same thermal calibration and switching characteristics as the part that left the factory with your generator.
- Exact Manufacturer Fit — this is a direct replacement for the original Nippon Thermostat unit, connecting to the existing harness and mounting points without modification.
- Thermal Protection Integrity — a correctly functioning thermostat switch allows the generator's protective circuit to respond accurately to engine temperature; a faulty unit can lead to missed shutdowns or nuisance trips.
- Serial Number Verification Recommended — Honda updates part numbers across production runs, so cross-check your generator's serial number against the compatibility table to confirm this is the correct switch for your unit.
- Fits EV4010, EV6010, and EVD4010 RV Generators — coverage across all three models in Honda's EV RV generator line makes this the right sourcing point for fleet and mixed-unit service situations.
The engine thermostat switch monitors engine temperature and triggers a signal to the generator's protection circuit when a thermal threshold is reached. When the switch functions correctly, the system can respond to an overheating condition before damage occurs; when the switch fails — either sticking open or closed — the generator may either shut down prematurely under normal load or fail to respond to a genuine overheat event. Replacing a worn or out-of-calibration switch restores the accuracy of that thermal response and keeps the generator's built-in protection working as Honda designed it.
