Old coolant turns acidic and eats at the radiator and water pump from the inside. Most makers call for a flush every 30,000 to 50,000 miles or every 2 to 5 years.
- Full system drain and flush
- Refill with correct coolant for your vehicle
- Hose and cap inspection included
Cooling System Repair by the Numbers
Heat is hard on cars. AAA reports that its roadside calls peak in summer, at 8.3 million calls. AAA also notes that most modern coolant is good for at least five years and 50,000 miles. Our summers push engines hard, so we check coolant condition on every cooling call.
Read why cars overheat in summer heat. A blown head gasket may need engine repair. If you are stuck on the road and running hot, our roadside team is on call 24/7.
Supercanic figures come from our own job records, September 2025 to September 2026.
