Owning a vehicle comes with the responsibility of taking care of it long after you drive off the dealership lot. This means investing time and money into caring for your car, regularly changing the oil, rotating the tires, and replenishing fluids.

One aspect of preventative maintenance you may not know much about it radiator upkeep. There are certain steps you can take to help maintain a properly functioning radiator.
