Overheating: Allowing your coolant level to run low can cause damage to your head gasket. When coolant isnât available to pull engine heat from your block and heads, the extra heat can cause expansion on your head gasket, which often results in a blown head gasket.
Why would a bad head gasket cause the coolant reservoir to fill up? I noticed my car was overheated today, so I pulled over. It only took maybe a minute (with the car off, hood open, and fan on) for the temperature gauge to start falling, so I figured that I probably hadn't done any major damage.
