2 Wire Coolant Level Sensor
Model: SensorMass202500612001
Induction method: magnetic induction
Product type: sensor switch
Maximum switching voltage: 24VDC
Description:
The 2-wire coolant level sensor provides a fail-safe solution for monitoring engine coolant reservoirs. This robust switch-type sensor operates on a simple open/closed circuit principle: when submerged in coolant, it completes the circuit, while low fluid levels trigger an open circuit. Compatible with standard warning systems, it delivers instant low-coolant alerts to prevent overheating damage – making it an essential, cost-effective protection component for any vehicle platform
Features
- Corrosion-Resistant Construction
- Universal Compatibility
- Zero-Calibration Installation
- Overheat Damage Prevention
Application
- Heavy-duty trucks, fleet vehicles, OEM replacement programs.

How does this sensor detect low coolant?
It operates as a simple switch circuit:
Submerged in coolant: Current flows (CLOSED circuit → “OK” signal)
Exposed to air: Circuit breaks (OPEN circuit → triggers dashboard warning light)
No complex calibration needed – pure binary reliability.
What vehicles is it compatible with?
Universally compatible with:
Voltage systems: 12V (cars/light trucks) and 24V (heavy-duty)
Reservoirs: Fits 95%+ OEM plastic/metal tanks (GM, Ford, RAM, Volvo, etc.)
Warning systems: Integrates with standard low-coolant indicator circuits
