The cooling system plays a vital role in the overall functionality and longevity of a vehicle.
They still have wax, but today’s thermostats use electronics to deliver precise temperature control.
The condition of the coolant has a direct relationship on the health of the cooling system.
There are three basic formulations of heavy-duty antifreeze/coolant.
A number of potential problems can be traced back to the antifreeze/coolant.
Modern cooling systems do a lot more than the simple name suggests.
With modular hoses taking on more functions and complexity, that means they have more potential failure points than traditional hoses.
Water pumps can fail prematurely due to corrosion inside the cooling system or from an imbalanced water-pump shaft. But in most instances, water pumps fail because of shaft leaks.
A dirty cooling system and airlocks reduce cooling capacity and can lead to serious issues such as pre-damage to the water-pump mechanical seal.
Longo’s experience and knowledge of the automotive industry is extensive and spans more than three decades.
Air filters, cabin air filters, oil filters and (sometimes) fuel and transmission filters are important maintenance parts that typically are replaced according to a time and/or mileage schedule.
