The radiator is a major part of your vehicle's cooling system that works together with the engine cooling fan, water pump and thermostat to maintain the proper engine temperature by removing absorbed heat from the engine coolant.
Your engine cooling system contains Antifreeze + Engine Coolant. Over time leaks may develop. You may notice colored water under your vehicle's engine area. This is a sure sign of a coolant leak.
Flushing the cooling system will help prevent contaminating the new radiator. Always use the correct type of new Antifreeze + Engine Coolant. Dispose of used engine coolant just like used engine oil.
