Types of Automotive Cooling Systems
Automotive cooling systems are primarily divided into two types – air-cooled and water-cooled systems. Air-cooled systems are extremely rare and are usually found on older Porsche engines, vintage Beetles, ‘69 Corvairs, and similar. All in all, air-cooled engines are obsolete by modern standards, which is why we’ll mainly focus on water-cooled designs for the sake of this guide.
Water-cooled systems are further divided into Different types — pump circulation, pressurized cooling system.

HOW DOES THE COOLING SYSTEM WORK?
Fire is one of the greatest discoveries we’ve made as a species. Nothing has come as close to being as useful as fire and there’s not a day that goes in our lives without using it in one way or the other — including transport. While the electric evolution is in full force, the majority of vehicles on the road today continue to be powered by combustion engines.
Combustion engines convert fuel into heat energy, and part of this heat energy is converted into mechanical energy. And just like any other application that uses fire, heat is a by-product. The heat an engine produces, however, has to be constantly kept in check and that task falls on the shoulders of the cooling system. A cooling system in a vehicle consists of multiple individual components that have simple but important roles, and today we’ll tell you all about it!
Types of Automotive Cooling Systems
This cooling or circulation system makes use of a pump that’s powered by the engine.
While the impeller thermosyphon cooling system made use of an impeller driven by the engine, this system uses a centrifugal pump. The pump is connected to the engine usually with the belt, and it ensures that there’s a sufficient flow of water throughout the cooling system.
Impeller Thermosyphon Cooling System
The impeller thermosyphon cooling system added an impeller to the arrangement mentioned above. This was considered to be an improved version of the thermosyphon cooling system as the impeller it used aided cooling. Apart from the additional cooling provided by the impeller, how this cooling system worked was identical to the thermosyphon one. It also depended on the density difference present between higher temperature and lower temperature water.
