If the coolant is dripping off of the starter, it could be an indicator that there is a coolant leak coming from the engine block, a heater hose or a coolant hose. You should first look for any visible signs of coolant leaking such as pooling on top of the engine or on the ground underneath the car. Check for any cracked hoses or damaged radiator. Check the water pump and thermostat housings for signs of leakage. It is also recommended to carefully inspect the coolant temperature sensor, as well as any freeze plugs or the head gasket that could be causing the problem. It is important to fix any coolant leaks as soon as possible, as a lack of coolant can lead to engine overheating and potentially serious engine damage.
