What kind of coolant does an engine radiator use?
Radiator (engine cooling) Engine coolant is usually water-based, but may also be oil. It is common to employ a water pump to force the engine coolant to circulate, and also for an axial fan to force air through the radiator.
How is the cooling rate of the radiator controlled?
On modern vehicles, further regulation of cooling rate is provided by either variable speed or cycling radiator fans. Electric fans are controlled by a thermostatic switch or the engine control unit. Electric fans also have the advantage of giving good airflow and cooling at low engine revs or when stationary, such as in slow-moving traffic.
What happens if there is too much coolant in the radiator?
Allowing too much flow of coolant to the radiator would result in the engine being over cooled and operating at lower than optimum temperature, resulting in decreased fuel efficiency and increased exhaust emissions.
What does radiator stand for in automotive category?
Radiator (engine cooling) From Wikipedia, the free encyclopedia. Jump to navigation Jump to search. A typical engine coolant radiator used in an automobile. For other uses, see Radiator (disambiguation). Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft.

Can a 2 row aluminum radiator dissipate heat?
To help illustrate the heat-dissipation capabilities, a two-row aluminum radiator featuring 1-in. tubes will dissipate heat roughly equivalent to a five-row copper radiator that features .500-in. tubes. What are the pros and cons with regard to materials?
