FAQ:

Q: Why is my coolant disappearing?

A: Why Is Coolant Disappearing From Reservoir Secretively? The Faulty Reservoir Cap There may be times that the reservoir radiator cap may turn out to be faulty. … Bad Head Gasket A head gasket is a component that is sandwiched between the engine block and the cylindrical head within the combustion engine. … Invisible Leakage Points

Q: Why is the coolant reservoir empty?

A: The coolant reservoir on your Accord is connected to the radiator, and allows coolant to flow back and forth between the two as it heats and cools. If the coolant reservoir is completely empty, you can’t just refill it. You need to check the level of coolant in the radiator as well.

Q: Why is radiator losing coolant?

A: If a radiator is unable to sustain pressure, the engine can overheat and lose coolant. A degraded shaft seal in the water pump allows coolant to escape out of the vent house. In a two-piece water pump with a backing plate, the gasket between the backing and the housing is prone to leaking.

Q: Is overfilling antifreeze reservoir bad?

A: If, on the other hand, you overfill the reservoir after the system has been bled, one of two things will happen. If the reservoir is not GROSSLY overfilled, it will always just have slightly more coolant than normal until the excess is lost due to evaporation.
