Checking your coolant level could be the difference between a blown engine and a safe journey. Especially if you live in a hot climate or tow on a regular basis, checking how much coolant you have is ...

As engines get very hot, coolant helps distribute heat to help prevent overheating and engine damage. It also adds antifreeze protection and acts as a lubricant for some of the engine’s components. If ...

Faster is not better when it comes to engine coolant flow rate. The purpose of a radiator is to support heat transfer, which is a time-dependent process. As Flex-a-Lite explains, to move the heat from ...

Engine overheating is rarely the result of a single failure. It usually happens when several small weaknesses in the cooling system line up, from low coolant to a stuck thermostat or a failing fan. To ...

Understand the difference between coolants, and how to look for problems. Coolant (sometimes referred to as antifreeze or radiator fluid) is used to regulate your engine temperature and prevent it ...

Several components in your car hold coolant, often called antifreeze, and any of them can get a hole or develop a leak. If your car loses too much coolant, its engine could overheat. Coolant is also ...

You've built a great engine with lots of power. Now you need to keep it cool. All too often we see guys build fantastic cars, but neglect to pay attention to a critical component that keeps everything ...

The coolant only re-circulates through the engine. As the engine temperature rises, thermostat opens slowly and allows coolant to flow through the radiator, to bring the cooling system into action. In ...

New advanced engines and cooling systems are changing cooling system maintenance requirements. Service technicians and fleet managers should review their preventative maintenance (PM) strategy and ...

Engineers design modern engines to run in a narrow temperature window where power, efficiency, and emissions all line up. The ...
