Coolant for solara wagon 6 cylinder

Coolant is for the cooling system,the cars engine must be cooled, there is a radiator , hoses and fans. the coolant is also used to supply heat to the inside of the car in winter conditions or cold days.The radiator which is bolted on the front of the car stores coolant (antifreeze) the coolant is then pumped through the engine by the waterpump, there is a thermostat that regulates the coolant flow. when the coolant in the engine reaches a certain temp. 190 degrees the thermostat opens and allows cooler coolant to enter the engine to keep it from overheating, the coolant that comes out of the engine then flows through the radiator and the fans are turned on by the computer to cool the coolant as it flows through the radiator. this goes on and on to keep engine operating around 170- 190 degrees,If the coolant does not cool the engine then engine damage will occur.
coolant is also used to keep for freezing in cold temps, the coolant is mixed 50/50. half coolant and half water. if water was used it would freeze and in the summer it would boil and is not a good cooling source.hope this is helpful.
