Radiator Repair Services

Keep your engine cool and your vehicle running smoothly with radiator repair and fluid exchange services at Firestone Complete Auto Care.

RADIATOR SERVICE OVERVIEW

  • Summary: Helps prevent overheating; includes coolant fluid exchange, pressure test, and optimal cooling restoration. Some call this a “radiator flush,” but our technicians perform a coolant exchange following your OEM procedure—usually a drain & fill or controlled exchange, not a generic flush. This ensures safe, thorough cooling system service that matches factory specifications.
  • Service Time: We’ll confirm the work after inspection; leaks or worn parts may require repair and your approval.
  • Service Interval: Typically, every 100,000 miles or 3–5 years, refer to your vehicle’s manufacturer recommendation specified in your owner’s manual. Make sure to check your owner's manual.

 

WHAT'S INCLUDED

  • Complete coolant fluid exchange, or “flush”. We follow your OEM procedure—often a drain & fill or controlled exchange, not a generic flush.
  • System pressure test and radiator cap inspection.
  • Hose and clamp visual inspection; thermostat, water pump, and heater core operation.
  • Comprehensive leak detection and topping off coolant.
  • Disposal of old coolant per environmental regulations

Radiator Warning Signs

  • High temperature gauge, sweet coolant smell, visible leaks (green, orange, blue, pink fluid).
  • Low coolant reservoir, poor heater performance, engine overheating, or steam from under hood.

Safety Note: Overheating can cause severe, irreparable engine damage. If your temperature gauge spikes or steam appears, immediately pull over safely and schedule service.

COMMON RADIATOR REPAIR QUESTIONS

HOW OFTEN SHOULD I GET A RADIATOR FLUID EXCHANGE?
Regular radiator fluid exchanges help prevent the buildup of particles and debris within the car's cooling system. If a car goes too long without a radiator fluid exchange, those particles and debris can block passages within the radiator and hinder its ability to keep the engine cool and running at normal operating temperatures. Check your vehicle manufacturer's recommendations for a radiator fluid exchange service, typically every 30,000 miles.
WHEN SHOULD I GET A RADIATOR FLUID EXCHANGE VS. A RADIATOR REPAIR?
A radiator fluid exchange cleans your vehicle’s cooling system and recharges it with fresh coolant. A well-maintained radiator can last up to 10 years, but wear and damage can have you coming in earlier for radiator repair. Follow your vehicle manufacturer’s guidelines for when to schedule a fluid exchange. If you notice leaks or signs of overheating, schedule a repair appointment.
HOW MUCH DOES A RADIATOR REPAIR COST COMPARED TO A RADIATOR FLUID EXCHANGE?
It’s worth staying on top of radiator maintenance because radiator fluid exchanges cost significantly less than a full radiator repair. Radiator fluid exchanging is a type of preventative maintenance that requires less labor and fewer parts and typically costs no more than $200. A radiator repair includes thorough diagnostics and, depending on the damage and parts needed, can start at $300 and up.
