3 reasons why your radiator has cracks.
 

#1. Clogged coolants.

In the internal components of car radiator, dirty coolants might cause corrosion or rust. Once these have formed, cracks and holes may appear, allowing coolants to leak. Because coolants are crucial for keeping your engine operating in optimal condition, leaking coolant is among the biggest problems you'll face as a car owner.

Engine coolants should be replaced every 3 years, according to the manufacturer's recommendations. Some vehicles may last more than 3 years, whereas others should be replaced every 2 years. You can ensure that the engine runs at its operating temperature, so that radiator cracks are avoided by using new and clean coolant.

#2. Debris

In case you travel off-road frequently, you might increase your chances of developing radiator cracks. Road debris may slam against the radiator when operating at high speeds, causing cracks to grow over time. Worse, the incident may have damaged the radiator fan, necessitating the replacement or repair of two critical components.

As a result, it is advised that you exercise caution while driving, particularly on highways. So if you realize the road you're traveling on is littered with debris, don't tailgate the car ahead of you. You'll avoid debris blowing into your car's radiator this way.

#3. Extreme weather

Car radiators struggle to cool themselves in high-temperature environments, resulting in overheating. Unwanted problems, such as holes or cracks through which coolants leak, are more likely in an extremely hot radiator.

Radiator cracks can also be caused by extremely cold temperatures. Some coolants have a tendency to freeze and then expand within radiator internal parts, causing harm. To avoid radiator cracks, keep your automobile in a garage with stable temperature in case you don’t planning to use it for an extended period of time.
