To add antifreeze to the radiator reservoir, unscrew the reservoir cap, and pour the coolant in the reservoir tank until it reaches the full line. You need antifreeze, otherwise known as radiator coolant, that is one part coolant and one part water. Do not remove the reservoir cap if the engine is still hot.Know More
Locate the white, translucent coolant overflow tank. Locate the markings on the tank that indicate the high and low levels. If there is no overflow tank, unscrew the reservoir cap, and look inside. If the coolant is near or below the low level, or if you cannot see the coolant's level when you look inside the tank, the tank needs to be filled.
If the coolant in the tank is dirty, replace it. Place a bucket underneath the vehicle in the spot where the reservoir tank is located. Locate the radiator plug located underneath the tank, and remove it. Allow the coolant to drain in the bucket. Replace the radiator plug, and secure it.
Unscrew and remove the reservoir cap. Pour the coolant in the tank until the coolant reaches the tank's full line. Screw the cap back on, and secure it tightly.
A person can determine if the radiator needs flushed out by checking the color of the coolant inside. This is done by loosening the drain valve.Full Answer >
A car's radiator may need to be replaced if it experiences consistent leaks, if there is extensive rusting on the interior and core, or if it cannot process coolant properly. Each scenario can be caused by a lack of consistent maintenance, a faulty part or damage from an accident.Full Answer >
A bad radiator cap can cause the coolant to boil over from the reservoir or the engine to overheat. The cap is an integral piece of an engine's cooling system as it retains the coolant´s pressure.Full Answer >
A radiator overflow tank collects the expanding coolant that is heated by the engine and recycles it back into the coolant system once it loses enough heat. The radiator overflow tank works in conjunction with the radiator cap to protect the engine and prevent coolant loss due to overflow, according to HowStuffWorks.Full Answer >
