Auto Cooling System Repair Services in Spokane, WA

Your vehicle’s cooling system works tirelessly behind the scenes to protect it from the scorching summers and freezing winters in Spokane, WA. From regulating engine temperature to preventing freeze-ups, this vital system ensures your engine runs reliably under all conditions. At Tune Tech Full Service Auto Repair, we specialize in car cooling system repair and radiator service at both of our Spokane locations—North Monroe Street and North Division Street. With certified technicians and high-tech equipment, we deliver fast, precise repairs that extend your engine’s life.

Why Your Cooling System Matters

Your car’s cooling system circulates coolant through the engine block, cylinder heads, and radiator to absorb and dissipate heat. A well-maintained system ensures:

• Optimal engine temperature for maximum efficiency

• Prevention of costly overheating and engine damage

• Clear visibility thanks to heaters and defoggers

• Protection from freeze-ups during winter months

Signs of cooling system trouble include fluctuating temperatures, warning lights, visible leaks, or foamy coolant in the overflow tank. Ignoring these warning signs can lead to head gasket failure, warped cylinder heads, or a cracked engine block. That’s why reliable radiator service and cooling system repair are so critical.

Common Cooling System Issues We Repair

At both our North Monroe Street and North Division Street locations, we diagnose and fix all types of cooling system issues:

• Coolant Leaks – From hoses, hose connections, radiator tanks, and water pumps

• Clogged Radiators – Sludge, rust, or debris that restricts coolant flow

• Faulty Water Pumps – Leaks or bearing failure that compromise circulation

• Thermostat Malfunctions – Sticking open or closed, causing mis-regulated temperatures

• Cooling Fan Failures – Electric fan or fan clutch malfunction that hinders engine cooling

• Radiator Cap & Overflow Tank Issues – Leaks or pressure loss that affect system performance

• Air Entrapment in System – Causing erratic temperature readings or overheating

• Corrosion & Electrolysis – Acidic coolant corroding internal passages

• Heater Core Problems – Warm air not reaching vents due to blockage or leaks

With a detailed inspection and advanced diagnostics, we locate issues quickly and recommend targeted repairs, saving you time and money.

Radiator Service & Coolant System Maintenance

Routine maintenance keeps your cooling system in top shape and helps avoid expensive breakdowns. Our comprehensive radiator service includes:

1. Coolant Flush – Draining old coolant and flushing out sediment or corrosion

2. System Pressure Test – Identifying hidden leaks in hoses, radiator, or water pump

3. Inspecting Belts & Hoses – Checking for cracks, wrinkles, or soft spots

4. Thermostat Inspection – Ensuring proper opening/closing and temperature control

5. Radiator Panel Cleaning – Removing dirt or debris that impedes airflow

6. Refill with OEM Coolant – Using manufacturer-approved coolant to protect against scale, corrosion, and freeze-up

7. Bleed Entire System – Removing trapped air to prevent hot spots and false temperature readings

We recommend completing cooling system service every 30,000–60,000 miles—or sooner in vehicles under heavy climate strain.

Preventative Car Cooling System Tips

Avoid major repairs and costly downtime with these maintenance tips:

• Monitor coolant level monthly and top off before it drops

• Inspect hose and radiator condition at each oil change

• Replace coolant at factory-recommended intervals

• Watch temperature readings—address fluctuations early

• Clean radiator fins as part of seasonal inspections

• Service heater cores every two years or at coolant flush intervals

Many failures develop slowly—catching them early saves money and protects your engine.

Frequently Asked Questions (FAQs) About Cooling System Care

How often should I have my coolant changed?
Most manufacturers recommend coolant replacement every 30,000–60,000 miles. Older vehicles, or those operating under heavy strain, may need more frequent service.

Why is my engine overheating on hot days only?
This could indicate a weak fan clutch, failing electric fan, low coolant, or trapped air in the system—all of which we can diagnose and fix.

Can I drive my car if the coolant is low?
Don’t. Even a short trip with low coolant can cause overheating and lead to cracked heads or gasket damage. Have it serviced immediately.

Does radiator repair include replacing hoses?
We inspect hoses during service and can replace them if they’re cracked, soft, or leaking to ensure your system stays sealed and pressurized.

What kind of coolant do you use?
We use OEM-approved coolants—whether it’s extended-life G05, DEX-COOL, or European phosphate-free formulas—to match your vehicle’s manufacturer specifications.

What causes heater performance to drop?
Poor heating inside the cabin often stems from coolant issues—leaks, air locks, or thermostat failure. Heater diagnostics are included in every cooling system repair.

How Your Cooling System Works

The cooling system regulates engine temperature by circulating coolant through the radiator, water pump, thermostat, and hoses. This process prevents the engine from overheating and keeps everything running at an optimal temperature. If any component fails, your car’s performance and longevity can be at risk. A properly working cooling system ensures your engine operates efficiently and helps avoid costly repairs.

Signs Your Cooling System Needs Service

Several warning signs indicate your cooling system may need attention. If you notice steam coming from the hood, a sweet-smelling odor inside the cabin, or coolant leaks under your vehicle, it’s time for a professional inspection. Other signs include an overheating engine, fluctuating temperature gauge readings, or a sudden drop in coolant levels. Ignoring these issues can lead to major engine damage, so it’s best to address them as soon as possible.

Cooling System Services We Offer

At Tune Tech, we specialize in diagnosing and repairing cooling system issues to keep your vehicle running at its best. Radiator repairs and replacements ensure that heat dissipates properly, preventing your engine from overheating. Water pump service keeps coolant flowing efficiently, maintaining optimal engine temperatures. If your thermostat is faulty, replacing it helps regulate temperature and prevents overheating or excessive cooling. A coolant flush removes debris and contaminants, allowing the system to function properly. Hoses and belts are also inspected and replaced when necessary to prevent leaks or unexpected breakdowns.

Preventative Cooling System Maintenance

Regular maintenance is essential to keep your cooling system performing well. Checking coolant levels often and scheduling periodic system inspections can help detect problems before they become major issues. A coolant flush every 30,000 to 50,000 miles removes buildup and prevents corrosion, helping extend the life of your radiator, water pump, and other cooling system components. Preventative care reduces the risk of overheating and keeps your vehicle running efficiently year-round.
