Evans Cooling Systems makes Arctic coolant gallon-sized
Evans Cooling Systems Inc.’s Arctic coolant in now available in gallon-size containers. Designed specifically for use in environments as cold as -60°F, Evans Arctic waterless coolant will not damage radiator tubes or cause blocks to crack because it shrinks when it solidifies at temperatures below its -60°F freezing point, according to the company. Evans noted
Webasto introduces coolant heating solutions
Webasto, a manufacturer of vehicle and equipment heating solutions, introduced its new Thermo Pro 90 and Thermo Pro 50 heating systems. The Thermo Pro 90 engine-off coolant heater offers new features specially designed for use in specialty commercial vehicles and off-highway equipment. It offers automatic high altitude adjustment up to 11,000 ft., improved fan motor
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
Leveraging the efficiency of air and coolant heaters
One of the biggest demands for power comes in the form of heating sleeper cabs. Espar manufactures diesel-fueled bunk/cab heaters, as well as engine pre-heating options. Espar options are available through every truck manufacturer and are utilized by manufacturers like Thermo King and Bergstrom. “Fleets are starting to realize these same idle-reduction savings opportunities also
Penray introduces synthetic media heavy-duty coolant filters
The Penray Cos. Inc. introduced a new line of heavy-duty coolant filters featuring synthetic media with triple-layer engineering. In addition to the synthetic media, many of these new filters incorporate Penray’s Need-Release technology, which introduces coolant additives and fortifiers on an as-needed basis, stabilizing the coolant for optimum effectiveness. Penray also offers synthetic media filters for
Ten maintenance tips for heavy-duty engine coolant systems
More than half of heavy-duty engine failures are due to improper maintenance. The coolant system is responsible for removing approximately 30% of combustion heat of heavy-duty engines, while more than 53% of premature engine failures are due to improper maintenance, says Paul Bandoly, fleet manager Wix Filters. Proper understanding of coolant types and adherence to
Charting coolant filters choices
According to Jim Watson, engineering director, engine liquid filtration at Donaldson Co., “While heavy EGR coolant systems may have increased coolant thermal cycling and accelerated coolant additive depletion, coolant filter problems related to heat have been noted. Coolant conditions may need to be checked frequently to ensure proper coolant chemical balance is maintained. It’s estimated
Engine coolant technology primer
PEAK Commercial & Industrial clarifies coolant technology: The company notes that extended life coolants (ELC) or organic acid coolants (OAT) provide up to 8% better heat transfer versus conventional coolants. Conventional coolants or inorganic additive technology (IAT) coolants protect metal by creating a thick layer of insoluble metal inhibitor salts. OAT coolants specifically target corrosive
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
