How many type of cooling system are used?

Answer 1

All cooling systems are basically the same with a few variations from car to car.

Here are few tips about those variations:

1)There are many different types of coolant available, and you should only use what is recommended for your vehicle. Even if it means that you have to buy a bottle of 'Honda' or 'Toyota' coolant from the dealership. Don't use "all makes, all model" coolants. The vehicle specific coolants were designed to mix with the various gasket materials and metals in the specific engine of your vehicle.

2)Overflow tanks. In most vehicles there is an overflow reservoir, and the radiator. Both of which need to be filled to the proper level. WITH ENGINE COLD remove the radiator cap and an the radiator should be full to the top. Then the reservoir should be filled to the "cold fill" line. The system works by allowing coolant to enter the overflow tank from the radiator as the engine gets warm and coolant expands. Then as the engine cools off and coolant retracts it will suck coolant from the overflow back in to the radiator.

Many other cars are equipped with a purge tank. In these systems there is only one cap on the reservoir. In this system the reservoir is pressurized and connected directly to the radiator.

3)Water pumps. All cars have a water pump. Some cars put them out in the open, and easy to access. Other cars bury them deep inside the engine and drive them by timing chains or belts.
