Proper cooling system maintenance is critical to the life of your diesel engine. This package of coolant test strips will allow you to properly check and maintain both the pH and glycol level of your cooling system. This package contains (50) test strips.
If the pH level of your coolant is low, we recommend using BG "Super Cool" additive to bring it back up to spec. A low glycol level indicates the need to replace the coolant (flush and refill).
