Cadillac xt5 car, what is the solution to the...

Dear customer, regarding the problem your car is facing, which is water leakage from the radiator, this is due to reasons including: 1- It may be due to changing the radiator or one of the parts in the cooling system and not adjusting the water level after that. Its main reason is that there is an increase in the radiator water, which leads to the water returning to the radiator and leaving the cover hole.
Therefore, the driver must make sure that there is no excess water in the engine of the car, which makes there is a vent for air from the cooling system, while adjusting the water level in the engine water bladder after adding water each time. Therefore, it is necessary to check that there is no defect in the radiator cap, because it leads to the emergence of a number of problems, including water leakage from it, and it may also lead to a rise in the temperature in the car.
2- The cause of this problem could be a malfunction or blockage in the thermostat, which causes an increase in pressure inside the engine water stream. Here, after the pressure rises, it will search for any weak place in the cooling system in your car to get out of it. If the location of the radiator cover is weak or defective, water will leak. from that point on.
Radiator blockage can lead to high pressure inside it and thus water out of the radiator cap, and also lead to high engine temperature. 3- Damage to the engine head, which is called the cylinder head or the cylinder head, or damage to its gasket. In this case, this gasket is changed immediately so that the problem does not worsen and damage the entire engine. These are the most important reasons that lead to water leakage from the coolant water cover of your car, so you must check it and try to fix it.
