Generally thru the use of a belt driven centrifugal pump


Why does a coolant have to travel through sealed pipes?

A few of the reasons: 1. So that the coolant does not leak out of the system. 2. So that the coolant can be made to circulate through the pipes (pressure is required). 3. So that Pressure can build up in the cooling system. This allows the coolant to reach a higher temperature before boiling. Once at its boiling point, the temperature will not rise, and additional cooling is inhibited.

How does the cooling sistem of a 1999 Oldsmobile alero works?

The coolant pump draws coolant from the radiator and circulates the coolant through coolant jackets in the engine cylinder block and the cylinder heads. The coolant is then directed back to the radiator. The system directs some coolant through hoses to the heater core in order to provide for defrost and passenger compartment heat. A surge tank connects to the cooling system. Pressurized coolant continuously flows through the surge tank and the process repeats


What are the operations of cooling system?

The cooling system in your car (radiator) cycles fluid (water with anifreeze/coolant) through your engine to keep it from overheating. It carries heat away from the engine.
