Cooling System Flush & Fill

Service Description
Coolant exchange makes sure your coolant can do its job keeping the engine cool. It also gets rid of any acid that builds up in the coolant, keeps the engine from locking up or boiling over, and helps prevent corrosion. Fresh coolant has chemicals to help slow any rust or corrosion, so your radiator will live longer, too. Let the pros at Big O Tires clean your system of old, tired, dirty coolant, and refill it with the correct, new coolant for your car or truck.

Included in your service:

  • Drain old coolant fluid
  • Replace with up to 2 gallons of new coolant fluid
