VIDEO: Internal Hose Degradation From Coolant
Andrew Markel discusses coolant hoses, and how electricity flowing through the coolant can lead to the inner hose liner breaking down and failing.
VIDEO: Coolant Scale Buildup On Cooling System Components
Andrew Markel explains how dried out coolant can break down and cause scale in certain components of the cooling system.
VIDEO: Why Are There Certain Coolants For Certain Vehicles?
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.
Diesel Coolants: The Right Fluid For The Right Application
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.
VIDEO: Coolant Temperature Sensor Diagnostics
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.
VIDEO: Avoid Water Pump Damage With The Correct Coolant Mix
Adam Redling explains the importance of properly mixing coolant and water to avoid damage to the water pump.
Cool Under Pressure: Choosing The Correct Coolant For The Job
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.
Volkswagen: Identifying And Mixing Factory Fill Engine Coolants
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.
Coolants Can Lose Their Ability To Protect The Engine
Coolant at 100,000 miles may look the same as coolant with zero miles. The real difference between good and bad coolant can’t be seen with the naked eye; it is in the chemistry.
Proper Coolant Selection Prevents System Degradation
Coolant is easily analogized to blood, both being liquids that are essential to the functioning of an entire complex system. The analogy extends even further though because, like blood, coolant has different types, and it’s not a stretch these days to say that swapping an OAT with an HOAT, or vice versa, is on the level of transfusing Type A blood with Type B.
