Why Your Cooling System Matters
Your vehicle’s cooling system works hard to maintain a stable engine temperature, prevent overheating, and protect internal components from damage. When any part of this system begins to fail—whether it’s the radiator, water pump, thermostat, or coolant hoses—your vehicle can quickly develop serious issues.
The cooling system:
-
Regulates engine temperature
-
Prevents overheating
-
Maintains proper fuel efficiency
-
Protects engine oil from thermal breakdown
-
Ensures long-term engine reliability
Ignoring cooling system problems can lead to warped cylinder heads, blown head gaskets, or complete engine failure. Early diagnosis and repair are essential.

Every cooling system is different, and our technicians tailor repairs to your vehicle’s specific needs.
Radiator Service & Repair
The radiator is one of the most important components in your car cooling system. When it becomes clogged, corroded, or damaged, it can no longer effectively dissipate heat.
Our radiator service includes:
-
Pressure testing for leaks
-
Radiator flushing
-
Cleaning of internal passages
-
Replacement of damaged or clogged radiators
-
Inspection of radiator hoses and connections
We ensure your radiator is functioning efficiently to keep temperatures in a safe range.
Coolant Flush & Fluid Exchange
Coolant (also known as antifreeze) plays a major role in preventing overheating, corrosion, and freezing. Over time, coolant breaks down and becomes contaminated, reducing its protective qualities.
Our coolant services involve:
-
Draining old coolant
-
Flushing the system to remove contaminants
-
Refilling with fresh, manufacturer-approved coolant
-
Testing for proper coolant concentration
-
Checking for leaks or weak components
Regular coolant flushes extend the life of your cooling system and reduce the risk of costly repairs.
Water Pump Replacement
The water pump circulates coolant throughout the engine. If it fails, your engine may overheat within minutes.
Signs of a bad water pump include:
-
Coolant dripping from the front of the engine
-
Grinding or whining noises
-
Engine overheating
-
Steam or smoke from the hood
Our water pump service includes complete replacement and inspection of related components such as belts and pulleys.
Thermostat Replacement
The thermostat regulates coolant flow based on engine temperature. When it becomes stuck open or closed, your engine may overheat or fail to warm up properly.
We replace:
-
Faulty thermostats
-
Thermostat housings
-
Temperature sensors
A functioning thermostat ensures your vehicle runs at the correct operating temperature.
Cooling Fan & Electrical Diagnostics
Cooling fans help maintain temperature when your car is idling or stuck in traffic. Faulty fans can lead to overheating even if the rest of the system is healthy.
We diagnose and repair:
-
Fan motors
-
Fan relays
-
Fuses
-
Wiring issues
-
Temperature sensors
Proper fan operation is essential for both domestic and import vehicles, especially during the hot summer months in Wisconsin.
Heater Core Repair
If your heater isn’t warming up or you smell coolant inside the cabin, the heater core may be failing. This component acts like a small radiator and plays a key role in interior temperature control.
Our heater core services include:
-
Leak detection
-
Pressure testing
-
Inspection of related hoses and connections
Proper heater core function is essential for comfort and safety during Wisconsin winters.
Cooling System Hoses & Belt Replacement
Rubber hoses and belts naturally wear over time. A burst hose or broken belt can cause sudden overheating.
We provide:
-
Cooling hose replacement
-
Serpentine belt replacement
-
Hose clamp inspections
-
Belt tension checks
Preventative replacement reduces the risk of roadside breakdowns.
Overheating Diagnostics
Overheating can be caused by several issues—including coolant leaks, thermostat problems, air pockets, clogged radiators, or failing water pumps. Our experts perform thorough testing to identify the exact cause.
Our overheating diagnostic process includes:
-
Pressure testing system components
-
Inspecting coolant flow
-
Testing thermostat operation
-
Checking radiator efficiency
-
Assessing fan performance
-
Scanning for engine-related fault codes
Identifying the root cause ensures the correct repair the first time.
