Matthews Tire & Auto did an excellent job finding the right tires for my SUV. I got an appointment in just a couple of days after I called. They also did an oil change. The shuttle service was excellent as well. I recommend Matthews to everyone!

Screw in a tire ... not good. Unrepairable. Easy to get the replacement ordered on Friday afternoon and got it installed first thing on Monday. 25 years of happy service. Just another reason why they get my business.

Frequently Asked Radiator Flush Questions

What is a radiator flush, and why is it necessary?

A radiator flush removes old coolant, debris and contaminants from the cooling system. It prevents overheating, corrosion and blockages, ensuring efficient engine cooling. Regular flushing extends radiator lifespan and maintains optimal engine performance. Most manufacturers recommend a flush every 30,000 miles or as specified in the owner’s manual.

What are the signs that my car needs a radiator flush?

Signs your car needs a radiator flush include engine overheating, discolored or dirty coolant, a sweet coolant smell, visible rust or debris in the radiator and poor heater performance. Low coolant levels or frequent overheating indicate potential blockages. Regular flushing prevents corrosion and maintains cooling efficiency.

How often should I get a radiator flush in Green Bay?

Most vehicles in Green Bay should have a radiator flush every 30,000 miles or every 2 to 5 years. However, if you’re frequently stuck in stop-and-go traffic along Mason Street or Military Avenue, your engine may be under more stress. If you’re frequently navigating high-congestion areas, your engine could be working overtime. This is often the case near busy intersections like Ashland Avenue and Walnut Street, or around the I-41 and West Mason Street roundabout. This is especially true during Green Bay’s harsh winters, when cold temperatures already place extra stress on your vehicle. Short trips and extended idling in these busy zones can put added strain on your cooling system. That’s why it’s smart to check your coolant more often and consider scheduling a radiator flush sooner if needed.

How long do radiator flushes take at your Green Bay shop?

Most radiator flushes take about 45 minutes to an hour. Our Green Bay location is conveniently situated near some of the city’s busiest roads, including Mason Street and Military Avenue. While we work on your vehicle, you can easily swing by Bay Park Square for some shopping, grab coffee near the stadium district or take care of errands along Oneida Street.

How much does a radiator flush typically cost?

A radiator flush typically costs between $50 and $150, depending on the vehicle, location and service provider. DIY radiator flush kits cost around $20 to $40. Professional service includes coolant replacement, system inspection and proper disposal of old fluid, ensuring optimal engine performance.

What are the risks of not performing regular radiator flushes?

Not performing regular radiator flushes can lead to coolant contamination, corrosion, overheating and engine damage. Debris buildup can clog the cooling system, reducing efficiency and causing costly repairs. Rust and scale deposits may damage the radiator, water pump and heater core, leading to system failure over time.

Can a radiator flush fix overheating issues in my car?

A radiator flush can fix overheating if the cause is coolant blockage, rust, or debris buildup. However, if overheating is due to a failing thermostat, water pump or head gasket, a flush will not resolve the issue. Diagnosing the root cause is essential for proper repair.

Are there any risks associated with performing a radiator flush on an older vehicle?

Performing a radiator flush on an older vehicle can pose risks, including loosening rust and debris that may clog passages, causing leaks in weakened hoses or seals and exposing pre-existing radiator damage. Inspect the cooling system before flushing to prevent potential failures.

Can I schedule a radiator flush with other services like an oil change or tire rotation?

Absolutely. Many customers combine a radiator flush with services like oil changes, tire rotations or seasonal inspections. Bundling services not only saves time but ensures your vehicle is fully road-ready in one visit. Just mention what you need when booking your appointment and we’ll take care of the rest.

Can cold Green Bay winters affect my cooling system?

Yes. Sub-zero temperatures and road salt can be rough on your radiator and hoses. A fresh coolant flush helps prevent freeze-ups and protects your engine when temperatures drop below zero, which is common in January and February here.

How close are you to Green Bay neighborhoods like De Pere, Allouez or Hobart for a radiator flush?

We’re conveniently located in Green Bay, just minutes from De Pere, Allouez, Bellevue, Hobart and other nearby neighborhoods. Whether you’re coming from the west side near Lambeau Field and Lombardi Avenue, or the east side along Main Street or Monroe Avenue, our shop is easy to reach.
