CORROSION & PITTING
Radiator
Buildup in the radiator greatly reduces the ability for the system to cool. Just 1/16 of an inch of buildup can reduce this capability by roughly 40%. Prestone® Antifreeze+Coolant prevents corrosion and keeps your radiator performing optimally.

Engine Block Cooling Channels
Buildup in the engine block cooling channels can make it difficult for coolant to travel. This can cause excessive heat, resulting in oil becoming too hot and thin and potentially damaging the whole system. Prestone® Antifreeze+Coolant prevents this buildup in the channel, avoiding this damage.

Cooling System Hoses
Buildup in the cooling hoses can cause major problems such as slowing coolant flow, reducing cooling and even clogs in the system from loose corrosion. Prestone® Antifreeze+Coolant prevents this corrosion and buildup, which keeps fluid flowing appropriately and heat transfer optimal throughout the system.
