To the best of my knowledge as MB coolant ages the ph increases, or becomes more basic not acidic. Using a swimming pool test strip determine the actual ph of the coolant. A ph reading between 7 and 8 is acceptable. If the ph exceeds 8 the coolant should be changed. Reportedly the ph of MB coolant right out of the bottle is 5.5 and as water is added the 50/50 mix becomes neutral (7).
