The Alltrux ATX23636 Coolant Level Sensor replaces Volvo OEM 22564822 and 22229570 and is designed for Volvo heavy-duty truck applications where accurate coolant level monitoring is essential for engine protection and cooling system reliability. This sensor installs in the surge tank and provides real-time coolant level data to the vehicle’s monitoring system, helping detect low coolant conditions before overheating or engine damage occurs.

Coolant level sensors play a critical role in maintaining proper engine cooling system operation by alerting drivers and control systems to coolant loss caused by leaks, system faults, or maintenance issues. A malfunctioning sensor can lead to delayed warnings, overheating risks, or diagnostic faults that impact vehicle uptime and reliability.

Engineered for durability in demanding commercial trucking environments, this replacement coolant level sensor delivers dependable signal accuracy under high heat, vibration, and extended service conditions. It is commonly used on Volvo VN model trucks, including certain applications equipped with Cummins ISX engines produced between 2007 and 2010, where coolant level signal reliability is especially important. Always verify application compatibility and connector configuration prior to installation to ensure proper fitment and dependable monitoring.
