FAQ:
Q: How much coolant should be in the radiator?
A: Although most radiators hold about 5 liters of coolant, you should check your manual to be on the safer side. Coolant should not be overflowing or too small as either can destroy the engine of your car. How much coolant does my car hold?
Q: Which way does coolant flow through the radiator?
A: In a down-flow radiator you have a tank attached to the top and bottom of the radiator core. The coolant enters the top tank and flows down to the bottom tank. As you’ve probably guessed by now, a cross-flow radiator has tanks on the left and right side . Coolant enters one side and flows across to the other.
Q: How does coolant circulate in a radiator?
A: It is circulated by a water pump which is driven by gears or a belt, that is behind the radiator fan, and usually attached to the engine just behind the fan. It pumps coolant through the engine. The coolant heats up, removing heat from the engine. The coolant then flows through the radiator hose to the radiator.
Q: How often to change your radiator coolant?
A: Car manufacturers recommend that it be done at least every other year or every 40,000 to 60,000 miles. Occasionally flushing the radiator before that period is not a problem as it helps to clean and prevent build up of dirt and sediment. Fresh antifreeze also contributes to protecting a vehicle from extreme cold or hot temperatures.
