When diagnosing cooling system problems, we check the entire system. Not just the radiator.

Important components include:

• Radiator cap
• Cooling fan relay
• Coolant reservoir
• Temperature sensor
• Heater core
• Radiator fan

Each part plays a role in maintaining the correct engine temperature.

A problem with any of them can lead to overheating.

Here are common warning signs.

Engine Overheating

If your temperature gauge climbs above normal, something is wrong. Low coolant, a stuck thermostat, or a failing radiator can cause overheating.

Coolant Leaks

Coolant often appears as green, orange, or pink fluid under your car. A leaking radiator, hose, or water pump could be the cause.

Steam From the Hood

Steam usually means coolant is boiling inside the engine. This is a serious overheating warning.

Sweet Smell From the Engine

Antifreeze has a sweet smell. If you notice it while driving or after parking, coolant may be leaking.

Heater Not Working

A clogged heater core or low coolant can prevent warm air from reaching the cabin.

Frequent Coolant Refills

If you keep adding coolant, there is likely a leak somewhere in the system.

If any of these problems sound familiar, it’s best to have the cooling system inspected before more damage occurs.

Our Cooling System & Radiator Services

Our technicians perform complete cooling system inspections and repairs using manufacturer-recommended procedures.

As a trusted automotive service center in Peoria, we work on cars, trucks, SUVs, and light-duty fleet vehicles.

Here are the most common cooling system services we perform.

Cooling System Diagnostics

Before replacing any parts, we run a full inspection to find the real cause of the problem.

Our technicians use tools like:

• Cooling system pressure tester
• OBD-II scanner
• Infrared thermometer
• Radiator leak detector

These tools help us locate leaks, clogged passages, or failing components.

Diagnostics often include:

• Pressure testing the cooling system
• Checking coolant condition
• Testing thermostat operation
• Inspecting the radiator fan and relay
• Checking hoses and connections

Once we find the issue, we explain what we found and what your options are.

Radiator Repair & Replacement

The radiator is the heart of the cooling system. Its job is to release heat from the coolant before it returns to the engine.

Over time, radiators can develop:

• Leaks
• Corrosion
• Clogged cores
• Damaged fins

Some issues can be repaired. Others require radiator replacement.

During radiator service we may:

• Remove and replace the radiator
• Clean radiator cores
• Replace worn hoses
• Refill the system with fresh coolant
• Perform pressure testing and leak detection

This restores proper coolant flow and prevents overheating.

Coolant Flush & Antifreeze Service

Coolant doesn’t last forever. Over time it breaks down and loses its protective properties.

Old coolant can cause:

• Rust inside the radiator
• Mineral deposits
• Clogged cooling passages

Most vehicles need coolant replaced every 30,000 to 60,000 miles.

A coolant flush removes old antifreeze and contaminants from the system. Fresh coolant, usually ethylene glycol or extended life coolant, is then added.

This helps protect your radiator, water pump, and heater core.

Thermostat Replacement

The thermostat controls coolant flow through the engine.

If the thermostat sticks closed, coolant cannot circulate. This quickly causes overheating.

Signs of a bad thermostat include:

• Engine overheating quickly
• Heater blowing cold air
• Temperature gauge fluctuating

Replacing the thermostat is a relatively small repair but an important one.

Water Pump Replacement

The water pump pushes coolant through the engine and radiator.

When the pump fails, coolant stops circulating. This leads to rapid overheating.

Signs of water pump problems include:

• Coolant leaks near the pump
• Grinding or whining noise
• Overheating while driving

Replacing a worn water pump restores proper coolant circulation.

Radiator Hose Replacement

Radiator hoses carry coolant between the engine and radiator.

Heat and pressure can cause hoses to crack or swell over time.

If a hose bursts, coolant escapes quickly and the engine overheats.

During service we inspect all hoses and replace any that show signs of wear.
