Product Description
Core Parameters：
- Part Number：7861-93-4520
- Type：Engine Coolant Level Sensor (Radiator Guard Mount)
- Structure & Material：High-strength corrosion-resistant metal body + precision sensing probe + IP67 rated waterproof electrical connector
- Function：Real-time monitors the coolant level inside the radiator guard, converting fluid level data into electrical signals for the vehicle controller
Function & Application：
- Level Monitoring & Alert：Accurately detects the coolant level in the cooling system. When the level drops below the safe threshold, it sends a signal to the dashboard to trigger a warning light or buzzer, alerting the operator to replenish coolant.
- System Protection：Prevents severe engine damage such as overheating, seized cylinders, or blown head gaskets caused by insufficient coolant, ensuring safe engine operation.
- Durability & Reliability：The anti-corrosion metal housing and waterproof connector resist dust, vibration, and extreme temperatures, making it suitable for the harsh operating environment of bulldozers.
- OEM Compatibility：Precision manufactured to Komatsu original equipment standards. Perfectly matches installation thread size, probe length, and electrical interface, enabling direct replacement of the old or damaged 7861-93-4520 sensor without installation modifications.
Application Scenario：
Suitable for maintenance and replacement of the engine cooling system (radiator guard area) in Komatsu D275A-5/D375A-5/D475A-5 series bulldozers. It is a key detection component to ensure normal heat dissipation and prevent high-temperature shutdown of heavy equipment.
