Coolant Leak Places

Leaking can cause several places such as ;

Radiator Leaks

The radiator is pressurized but exposed to rocks, vibrations, shocks and air flow in the front of the car. This can cause the radiator metal to rust or metal fatigue, causing coolant to leak.

Radiator Cap

This is the cap on top of the radiator or its expansion tank where you can check the coolant level in your car. It must be sealed to maintain pressure in the cooling system. However, if it is damaged, the cooling system will lose pressure, which can cause leaks.

Radiator and Heater Hoses

Hoses carry coolant from the engine and heater core to the radiator. As the hoses age, they can develop cracks or holes that cause coolant to leak from the hoses. This is especially common where the hose bends or where it connects to the radiator, engine or heater core.

Expansion Tank

The expansion tank contains additional coolant. It is connected to the radiator by a hose. The tank may leak if the container is broken, the lid is broken, or the hose is cracked or has a hole.

Water Pump

The water pump circulates the coolant and if it breaks, it can easily cause the car to overheat. If the seal fails, the seal does not work, or there is external damage, it can cause a coolant leak.

Thermostat

The thermostat regulates the temperature. If the seal breaks or fails, coolant may leak.

Heating Core

The heating core provides heat to the interior of the car. Any damage to the core or the hoses connected to it can cause a coolant leak.

Intake Manifold Gasket

The intake manifold gasket supplies air and fuel to the engine cylinders. This seal can fail and coolant can leak.

Head Gasket

The head gasket provides a seal between the engine block and the cylinder heads. If it fails where it is exposed on the outside of your car's engine, you may find a leak. However, this often happens internally, so you may not see a leak or coolant. A combination of oil and coolant is a sign of a possible head gasket failure.
