Radiator problemscan be prevented as long as proper care and maintenance is given attention to this crucial part of the cooling system. Remember that wear and tear as well as old age will contribute greatly to the efficiency of your radiator. The cooling system in your car is designed to maintain ideal engine operating temperature as tremendous heat is produced due to the process of combustion. Common radiator problems should be inspected immediately to prevent further engine damage.

To prevent damage to your radiator we recommend the use of vr-12. VR-12, is the most recent innovation in Additive Packages for your vehicle`s cooling system protection: Its exclusive and innovative composition protects your vehicle’s cooling components from rust and corrosion, reduces electrolysis providing better heat transfer, lowering temperature. Re-energize your antifreeze and boost your coolant, compatible with any brand, color or type of Antifreeze/coolant, works on both NEW & OLD cars and trucks.

Additionally the following information is useful to prevent damage to your radiator:

Step 1

Use the appropriate coolant for your car model. There are different types of coolant on the market and most are designed to prevent corrosion in the radiator. Check your owner’s manual to see what coolant is recommended since using the wrong type could actually speed up the corrosion process in your radiator.

Step 2

Mix the coolant with the appropriate amount of distilled water. Some antifreeze comes premixed and does not require any additional water to be added but many varieties need to be mixed in the radiator with 50% water. Some people think they need more antifreeze and less water during winter months but this can actually cause more corrosion of the radiator. Follow the instructions on the back of the coolant container to achieve maximum benefits.

Step 3

Check your radiator level regularly to ensure the engine has enough coolant to function properly. If the coolant level runs low, the engine will run hotter and the radiator can corrode faster. The coolant reservoir should be filled up to the appropriate line on the tank to make sure the radiator has an adequate supply.

Step 4

Flush the radiator once a year. Coolant is meant to protect against corrosion but the constant heat and pressure in the engine breaks it down over time. Completely changing the coolant supply annually guarantees the coolant can maintain maximum benefit against rust and corrosion.


  • Avoid mixing coolants as this can decrease effectiveness. Always flush the radiator prior to switching antifreeze types.


  • Never remove the radiator cap when the engine is hot. The coolant is under high pressure and very hot. It could shoot out and cause severe burns.
