Low Level Warning: Triggers a dashboard warning light when the coolant level drops below the safe threshold, alerting the driver to add coolant and prevent engine overheating.
-
Engine Protection: Integrates with the vehicle’s ECU to potentially limit engine power or trigger a safe shutdown in severe low-coolant conditions, safeguarding the engine from damage.
-
Durable & Sealed Design: IP67-rated waterproof and dustproof construction, with high-temperature-resistant materials to withstand coolant exposure and harsh operating conditions.
