What can be done to minimize improper top off of the ES Coolant?
The automobile industry has for years installed coolant recovery tanks to capture overflow coolant loss due to thermal expansion. These recovery systems are just beginning to be used in on-highway trucks and off-highway equipment. These systems provide a sizable storage capacity for top off coolant. Your other choice is to send jugs of ES Coolant with the truck for top off. Do not use concentrated ES antifreeze as a top off.
