Testing for Freeze Protection
Personal injury can result from hot coolant, steam and alkali.At operating temperature, engine coolant is hot and under pressure. The radiator and all lines to heaters or the engine contain hot coolant or steam. Any contact can cause severe burns.Remove filler cap slowly to relieve pressure only when engine is stopped and radiator cap is cool enough to touch with your bare hand.Cooling System Conditioner contains alkali. Avoid contact with skin and eyes.

245-5829 Coolant/Battery Tester Gp
Check the coolant frequently in cold weather for the proper protection against freezing. Use the 245-5829 Coolant/Battery Tester Gp to ensure adequate freeze protection. The tester gives immediate, accurate readings. The tester can be used for antifreeze/coolants that contain ethylene or propylene glycol. The tester is also used to check the condition of batteries (specific gravity). Instructions are provided with the tester.Making the Correct Antifreeze Mixtures
Adding pure antifreeze as a makeup solution for the cooling system top-off is an unacceptable practice. Adding pure antifreeze increases the concentration of antifreeze in the cooling system. Pure antifreeze increases the concentration of the dissolved solids and the undissolved chemical inhibitors in the cooling system. Add the antifreeze and water mixture in the same concentration as your cooling system. Refer to the engine Operation and Maintenance Manual.Testing the Supplemental Coolant Additive and the Glycol
Refer to the engine Operation and Maintenance Manual for further information about testing the cooling system.Testing for Air and/or Exhaust Gas in the Coolant
