Mazda Mx-3 Radiator
Causes and Signs of a Busted Mazda MX-3 Radiator
The Mazda MX-3's radiator regulates the amount of heat running around the engine. This part ensures that the motor performs at maximum efficiency. If the radiator fails and the engine bay gets too hot, you might end up with a car that overheats and resists moving. If you simply replace it without understanding why it happened in the first place, then you're most likely to have a repeat of your problem. The following are some of the common causes and signs a busted radiator:
The small thermostat in the cooling system is the critical device that reads and measures the amount of heat in the engine compartment. Depending on how hot it is inside, this triggers other parts to let more or less coolant and fluid in the system to regulate the temperature. If the thermostat malfunctions, then there would be an improper amount of liquid inside. This can result in overheating and damage to the radiator and the rest of the system. You can tell that your Mazda's thermostat is busted if you get inconsistent readings on the temperature gauge.
Leaks and punctures
Leaks and punctures on the radiator are avenues for water and radiator fluid to escape the system. All this liquid ends up on the ground instead of in the cooling system regulating the heat. Check your garage floor after the car is parked overnight and see if there's any. Minor leaks can be repaired. However, ones that are too big leave you with no other choice but a replacement of the whole part.
Rust on the surface of the radiator greatly lessens the integrity of the part. As the metal slowly gets eaten away, the chances of having leaks and holes increase. Corrosion builds up faster if you usually drive in a very dusty and dirty area. Weather also plays a role. Too much humidity negatively affects the metal. When it's too cold and snow salt is placed on roads, rust is made easier.
Blocked internal tubes
The tubes inside the radiator can also be blocked. This is caused by the decaying particles from the inner surface of the lines that were washed away and transferred by the flowing fluid. With no way of escape-assuming the radiator is free of leaks-it ends up simply restricting the free flow of coolant. Less coolant around means less heat regulated.
