RCPOWERCH Antifreeze Coolant Tester Automotive, Dual-Scale Hydrometer Coolant Tester for Winter and Summer, Accurate Radiator Fluid Testing for Cars, Trucks, RVs

• Dual-Scale Precision: This professional coolant tester automotive tool features 2-in-1 design with clear dual scales. The front measures freeze protection from -45°F to 10°F (-43°C to -12°C), while the back measures boiling point up to 265°F (129°C). With both °F and °C calibration, it provides fast, accurate readings to help prevent engine problems caused by freezing or overheating
• Quick Results: Using this radiator fluid tester is straightforward and efficient. Simply draw coolant up to the marked line, align the red plastic float with the center line, and read the pointer. For accurate results, gently tap the tester to release air bubbles and hold it vertically during measurement—ensuring precise readings every time
• Warm Up Engine: For accurate boiling point readings with this antifreeze tester for coolant, run the engine 10-15 minutes until warm (195-220°F). This ensures proper circulation-the pointer responds to true fluid temperature for reliable results
• Use NOTE: This antifreeze tester automotive includes important safety instructions: always wait 1-2 hours after engine operation before opening a hot radiator to avoid dangerous fluid spray. For accurate boiling point tests, run the engine 10-15 minutes until warm (195-220°F) to ensure proper coolant circulation before testing
• Convenient Storage: Featuring a lightweight and compact design, this anti freeze tester automotive tool easily fits into any toolbox. Its portable size allows for quick coolant checks whenever needed, whether in your home garage, at work, or on the go
