Coolant Level Warning Sensor for John Deere 5820 and Early 6120/6220 Series Tractors SKU: QT58672

Running low on coolant without warning leads to expensive engine damage from overheating. This sensor monitors coolant levels and triggers your warning system before temperatures climb, giving you time to shut down safely and investigate rather than facing catastrophic engine failure.

Why This Sensor Matters

• Alerts you to low coolant levels before engine temperatures become dangerous
• Prevents costly overheating damage that occurs within minutes of coolant loss
• Restores proper function to your early warning system when lights fail to illuminate
• Designed for the harsh thermal cycles of heavy-duty farm operation

Your John Deere engines generate serious heat under load pulling implements or running forage equipment. When this sensor detects dropping coolant levels, it provides the critical warning that protects thousands of dollars in engine investment. If you've been caught off-guard by coolant loss or your warning light isn't working during startup self-test, this sensor gets your protection system back online where it belongs.
