What to know about the Radiator:
The radiator execute a critical function; it prevents the engine from overheating. While operating, the engine generates heat. Coolant flowing through the system absorbs and removes extra heat from the engine. The coolant then goes through the radiator where it cools off and is later circulated back to the engine to absorb heat again.
A radiator has two tanks that are linked to each other via aluminum or brass tubes. When the coolant passes through these tubes, the radiator cooling fan blows air across the radiator to lower the temperature of the coolant. The tank is normally made of plastic, and it is common for it to crack and start leaking coolant. If the tank or the tubes break, coolant will leak , the vehicle will overheat and could cause severe engine damage. Radiators also tend to clog over time. When this happens, enough coolant will not flow through the radiator resulting in heat build-up, causing the engine to overheat.

Facts to Note:
When changing the radiator, it is best to also change the radiator cap and thermostat.
After your radiator is changed, it is best to have it checked for leaks, to guarantee that everything is in functioning order.
When the radiator is changed, the entire cooling system should be checked, especially the radiator hoses.
How to Fix:
Examine radiator for leaks.
Pressure test cooling system.
Take out and change the radiator.
Fill radiator with proper mixture of 50/50 coolant.
Recheck for leaks.
Follow the service upkeep schedule given by the manufacturer to get the coolant changed at consistent intervals. It is a good practice to change the coolant every 25,000-40,000 miles. Changing the coolant will make sure it is free of contaminants such as rust or scale that can block it from flowing through the radiator and engine. Given high engine temperatures, it is inevitable that the tanks in the radiator will eventually crack. The thermostat should be changed when replacing the radiator as well as any necessary radiator hoses.The system should also be flushed out of all old coolant to remove any contamination.

Common symptoms indicating you may need to change the Radiator:
Car is overheating.
Coolant (red, yellow, green fluid) is leaking.
Importance of this service:
If a faulty radiator is not changed, the overheating of the engine can potentially lead to serious internal engine damage.
