Andrew Markel discusses Nissan’s blue coolant in their modern vehicles, and how to use coolant color to determine the coolant’s previous service history.
Cooling systems and chemistry have changed a great deal since the mid-19th century, and the need for coolant has also been on the rise in today’s modern engines.
Andrew Markel discusses coolant hoses, and how electricity flowing through the coolant can lead to the inner hose liner breaking down and failing.
Andrew Markel explains how dried out coolant can break down and cause scale in certain components of the cooling system.
Andrew Markel explains how coolant is not meant to be mixed or switched. There are certain coolants for certain vehicles that must be used for long engine and gasket life.
Which antifreeze should you use in your diesel engine? It seems just when you think that things are starting to settle down, some spec changes. Engine oil has been a hot topic over the past several months and has seen many changes over the past 10 years.
If you have a vehicle in your shop with the fans running all the time, there may be a problem with the coolant temperature sensor. Andrew Markel explains.
Adam Redling explains the importance of properly mixing coolant and water to avoid damage to the water pump.
Modern coolants, in their many colors and compositions, have helped extend the service intervals and replacement schedules of cooling system components. Driven in part by the OEMs longer powertrain warranty, many components are engineered to last beyond this “magic number,” sometimes up to 100,000 miles.
Coolants G12+, G12++ and G13 are lifetime coolants when used exclusively in the coolant system (not mixed with other coolants). Coolants can be mixed, as shown in the chart in this article, but it is always a best practice to change the coolant due to reduced corrosion protection when coolants are mixed.
