Why should I consider replacing it?We at Advanced Auto Pros take your vehicle seriously and want to do our part to be sure that every car in Greeley is trouble free. One way that we do this is by checking your vehicle's antifreeze or coolant for freeze and corrosion protection every time you bring your car in for potential problems. We may have recommended that you replace your coolant based on freeze protection or PH level. We invite you to take 2 minutes and find out what this means to you and your vehicles reliability.
