I found myself with a dead car battery late in the afternoon! Called Matthews Tire and they told me to bring the car in immediately, which I did! Fifteen minutes later my battery was installed! The reception area where I waited was very clean and inviting. Terrific "service with a smile" from the two gentlemen that were at the reception desk!

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 Fond du Lac?

Most vehicles in Fond du Lac should have a radiator flush every 30,000 miles or every 2 to 5 years. However, if you’re regularly navigating stop-and-go traffic along Johnson Street, Main Street or near high-congestion spots like the intersection of Pioneer Road and Military Road, your engine may be working harder, especially during winter. Short trips and idling in these busy areas during cold Wisconsin weather can strain your cooling system, so it’s wise to check your coolant levels more frequently and consider flushing sooner if needed.

How long do radiator flushes take at your Fond du Lac shop?

Most radiator flushes take about 45 minutes to an hour. For your convenience, we’re located near some of Fond du Lac’s busiest and most accessible areas and just minutes from Main Street. It’s easy to drop your car off and swing back after running errands, shopping along West Johnson Street or grabbing coffee downtown.

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 Fond du Lac winters affect my cooling system?

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

How close are you to Fond du Lac neighborhoods like North Fond du Lac or Taycheedah for a radiator flush?
