How Antifreeze Protects Against Freeze Damage
How Antifreeze Protects Against Freeze Damage A machine can be parked overnight in perfectly good condition and still face a serious problem the following morning. If temperatures drop below freezing, water left inside its cooling system can turn into ice. As it freezes and expands, it can place pressure on components that were never designed […]
Coolant Maintenance Tips for Construction Fleets
Coolant Maintenance Tips for Construction Fleets An excavator working through a long shift on a dusty construction site has very different operating conditions from a truck traveling on an open highway. Radiators collect dirt, engines run under heavy loads, and machines may spend hours working in high ambient temperatures. Even a relatively small cooling-system problem […]
The Benefits of Premixed Coolants for Commercial Operations
The Benefits of Premixed Coolants for Commercial Operations A service truck arrives at a busy commercial workshop, and a technician discovers that one of the fleet vehicles needs a coolant top-off. The workshop has concentrated antifreeze available, but the mixing equipment is being used elsewhere. A technician needs to measure the concentrate, locate suitable water, […]
Why Cooling Systems Matter for Equipment Reliability
Why Cooling Systems Matter for Equipment Reliability A machine can have a powerful engine, a solid drivetrain, and a well-planned maintenance schedule, yet one cooling system problem can bring the entire operation to a stop. A blocked radiator, leaking hose, failing water pump, or neglected coolant can turn an otherwise productive workday into an expensive […]
Understanding Cavitation and Coolant Protection
Understanding Cavitation and Coolant Protection A diesel engine can run for thousands of hours without showing any obvious cooling-system problems. Then, during an inspection, a technician discovers small pits on the outside of a cylinder liner. In more serious cases, the damage may extend through the liner, allowing coolant to enter the combustion chamber or […]
How Coolant Chemistry Has Evolved in Heavy-Duty Equipment
How Coolant Chemistry Has Evolved in Heavy-Duty Equipment A heavy-duty engine built several decades ago and a modern diesel engine may perform similar jobs, but their cooling system requirements aren’t necessarily the same. Engine designs have changed. Manufacturers have introduced different materials, tighter engineering tolerances, and new operating requirements. Equipment also spends long hours working […]
The Benefits of Routine Cooling System Inspections
The Benefits of Routine Cooling System Inspections Cooling system problems don’t always give much warning before they become serious. Sometimes it’s a small coolant leak that goes unnoticed for weeks. Other times, dirt gradually blocks the radiator, or a worn hose finally gives way during a demanding shift. By the time the temperature gauge starts […]
How Seasonal Weather Affects Coolant Performance
How Seasonal Weather Affects Coolant Performance A vehicle or piece of heavy equipment that runs perfectly in mild weather may face a different set of challenges when the seasons change. Cold mornings, summer heat, and sudden temperature swings all affect the conditions under which an engine operates. The cooling system has to deal with those […]
Why Heavy-Duty Engines Require Specialized Coolants
Why Heavy-Duty Engines Require Specialized Coolants A heavy-duty truck pulling a full load up a long grade doesn’t have much room for a cooling system problem. The same is true for a generator running through a power outage or an excavator working an extended shift in hot weather. These engines are built to work hard, […]
Cooling System Maintenance for Industrial Equipment
Cooling System Maintenance for Industrial Equipment Coolant rarely gets much attention when an engine is running normally. The temperature gauge stays where it should, the reservoir looks fine, and there are no obvious leaks. It’s easy to assume the fluid can keep doing its job indefinitely. That’s not how it works. Coolant operates in a […]
