The first thing is the detection of the damage. The central part is the marking of the damaged point and the extent to which it is damaged.

If you want to treat the disease, then you have to diagnose the problem first. The exact and accurate diagnosis of the damage will let you help in the quick repair of your car without causing damage to it.

You can compare the rates of different mechanics in your area. The charges of the mechanic will be based on their skills and experience.

There will be a puddle formation under the car. If you still don’t find any such symptom, you have to open the car’s bonnet and remove the radiator’s cap.

If there is any presence of moisture, then it is also a sign and symptom of coolant leakage. You must also check the hoses with any crack or hole with a torch or any moisture on them.

If you still don’t find anything by the above methods, you have to check your car’s coolant level. The level of the coolant must be between maximum and minimum.

If it is lower than the minimum level, it also indicates the anti-freezing agent’s unwanted discharge.

If you are still unable to find the leakage, then we are afraid that you might have to spend some money for the diagnosis. The mechanic can charge for this thing about 40-60$.

If the head gasket is blown up, then it can cause the mixing of fuel and the coolant leading to significant damage to your car. It can lead to expensive repair and financial shock to your bank balance.

Sometimes, the cap of the radiator also breaks due to the temperature change. In winters, the plastic might get cracked and may lead to an outflow of the anti-freezing agent through that point.

Moreover, like the cap of the radiator, the expansion tank is also made up of plastic, whose function is to bring and take away the radiator’s coolant.
