Why does my coolant level keep dropping?

A leaking or blown head gasket will cause water to leak into the areas of the block where it was not designed to go.

This will cause the coolant fluid levels to drop without any noticeable leaks under the coolant reservoir, hoses or radiator.

To check for a faulty head gasket, pull the oil dipstick.
