Car Leaking Engine Coolant

What is Engine Coolant?

Engine coolant, also known as antifreeze, is a fluid that circulates through the engine of a car to help keep it cool. It is made up of a mixture of water and antifreeze, and it helps to prevent the engine from overheating by absorbing heat and transferring it to the radiator, where it is dissipated.

Causes of Engine Coolant Leaks

There are several different things that can cause an engine coolant leak, including:

A cracked or damaged radiator. The radiator is the part of the car that helps to dissipate heat from the engine coolant. If the radiator is cracked or damaged, it can leak coolant.
A leaking water pump. The water pump is the part of the car that circulates the engine coolant through the engine. If the water pump is leaking, it can cause coolant to leak out of the car.
A damaged or loose hose. The hoses that carry coolant through the engine can become damaged or loose, which can cause coolant to leak out of the car.
A blown head gasket. A head gasket is a seal that sits between the cylinder head and the engine block. If the head gasket is blown, it can allow coolant to leak out of the car.
