Cool down: A primer of coolant and additives
Today’s modern heavy-duty engines are being designed with a greater amount of aluminum components, including radiators, heater cores, oil coolers, charge air coolers, water distribution housings, piping and control valves. “Due to the higher aluminum content engines, one phenomenon that is being observed in the industry is that nitrite containing coolants may react with aluminum
Coolant compatibility: Know thy coolants
When it comes to a fleet’s extended life coolant concerns, look no further than the three C’s: Capabilities; Compatibility; and Contamination. The biggest concern for the fleets running organic acid coolants (OAT) and nitrited organic acid technology (NOAT) extended life coolant [ELC] is knowing which fluid should be in their system. Extended life coolants are
Keeping truck engines cool: The right coolant and coolant filter stand between you and engine repairs
The biggest factors surrounding engine coolant are maintaining engine temperatures, assisting in emission control and being plagued by chemical and particulate contamination, says John Gaither, director of heavy-duty engineering for Luber-finer. In addition, he notes, they often must handle rust, silicate drop out and scale, which is caused by an unbalanced system and needs to
