Radiator & Cooling System Service in Fishers, IN
Expert Cooling System Repair for European & Asian Imports
Central Indiana weather can put your cooling system to the test — from freezing Broad Ripple mornings to 90-degree afternoons on 116th Street in Fishers. Long commutes on Keystone Parkway in Carmel, stop-and-go traffic around downtown Noblesville, and weekend drives to Geist Reservoir all push your radiator, thermostat, and water pump to keep your engine at the right temperature. When your temperature gauge starts to climb or you spot coolant on the driveway, it’s time to act fast. At Hash Imports of Fishers, our ASE-certified import specialists provide radiator and cooling system inspections, repairs, and flushes using factory-approved fluids and OEM parts — keeping your European or Asian vehicle running cool and reliable from Westfield to Fishers and beyond.

Why Your Cooling System Matters
Your cooling system circulates coolant through the engine and radiator to regulate temperature and prevent damage from overheating. It also maintains optimal operating temperature for performance and fuel efficiency.
Neglecting maintenance can lead to:
Engine overheating or stalling
Coolant leaks or corrosion
Warped cylinder heads or gasket failure
Costly internal engine damage
Routine cooling system service protects your investment — keeping your engine running smoothly and efficiently.
Comprehensive Cooling System Services We Provide
Radiator Inspection & Replacement
We inspect your radiator for leaks, corrosion, or clogged cores that restrict coolant flow. If necessary, we replace it with a high-quality OEM or equivalent radiator to restore proper cooling efficiency.
Coolant Flush & Replacement
Over time, coolant breaks down and becomes acidic, which can corrode internal components. We perform a complete coolant flush using manufacturer-approved antifreeze (e.g., G13, HOAT, or OEM-specific formulations) to ensure compatibility and protection.
Thermostat & Water Pump Service
A faulty thermostat or worn water pump can cause temperature fluctuations or overheating. We replace these components using OEM-quality parts to maintain proper coolant circulation and temperature regulation.
Pressure Testing & Leak Detection
We perform pressure tests to locate leaks in hoses, gaskets, and radiator seams, preventing coolant loss and overheating before it becomes a major issue.
Cooling Fan & Sensor Diagnostics
Modern imports rely on electronically controlled fans and temperature sensors. We test fan operation and coolant temperature sensors using factory-grade diagnostic tools to ensure precise operation.
Our Oil & Filter Change Process
Our ASE-certified technicians follow manufacturer-recommended procedures for every oil service:
01
Engine Oil Drain & Refill
We remove all old oil, replace the drain plug gasket (when applicable), and refill with OEM-specified synthetic or hybrid-compatible oil suited to your vehicle’s exact requirements.
02
OEM-Quality Filter Replacement
We install manufacturer-approved oil filters that provide proper flow and filtration for your engine’s design — ensuring clean lubrication and reliable oil pressure.
03
Multi-Point Vehicle Inspection
Every oil service includes a complimentary inspection of your fluids, belts, hoses, brakes, and tires for early detection of potential issues.
04
Oil Life Monitor Reset
We use factory diagnostic tools to reset your service indicator, ensuring your maintenance schedule stays accurate and up to date.
05
Quality Assurance Test
Before returning your vehicle, we check for leaks and verify oil pressure and levels to confirm everything meets factory specifications.
Signs Your Cooling System Needs Service
If you notice any of these warning signs, it’s time for an inspection:
Engine temperature warning light
Steam or overheating under the hood
Coolant leaks under the vehicle
Fluctuating or unusually high temperature gauge readings
Sweet or chemical smell (indicating coolant leak)
Heater not blowing warm air
Ignoring these symptoms can quickly lead to serious engine damage.

Radiator & Cooling System FAQs – Hash Imports of Fishers, IN
Do you specialize in radiator and cooling system repair for import vehicles?
Yes — Hash Imports services European and Asian vehicles only, including Audi, BMW, Mercedes-Benz, Lexus, Toyota, Honda, Subaru, Mazda, and Volkswagen. Our ASE-certified technicians are trained to maintain and repair the advanced cooling systems these vehicles use.
Do you service diesel, EV, or hybrid cooling systems?
No — Hash Imports does not service diesel, fully electric (EV), or hybrid cooling systems. We specialize in gasoline-powered import vehicles and can service the standard cooling systems found in those models.
What does the cooling system do?
Your cooling system circulates coolant through the engine and radiator to regulate temperature, prevent overheating, and maintain optimal performance. It includes the radiator, water pump, thermostat, cooling fan, hoses, and sensors — all of which must work together for efficient operation.
How often should I have my coolant flushed or replaced?
Most imports require a coolant flush every 30,000 to 60,000 miles or every 2 to 4 years, depending on your manufacturer’s recommendation. Over time, coolant breaks down and loses its ability to protect against corrosion and overheating. We use OEM-approved coolants to ensure perfect compatibility.
What are the signs of a failing radiator or cooling system?
Common symptoms include:
- Steam or overheating under the hood
- Coolant puddles beneath the vehicle
- Temperature gauge running higher than normal
- Sweet, chemical smell (indicating coolant leak)
- Heater blowing cold air
- Low coolant warning or engine temperature light
If you notice any of these, schedule a diagnostic inspection immediately.
Can you replace a radiator that’s leaking or corroded?
Yes. If your radiator is leaking, blocked, or corroded, our technicians can replace it with an OEM or OEM-equivalent radiator to restore proper cooling performance. We also pressure-test the system afterward to ensure no additional leaks remain.
What type of coolant do you use?
We use manufacturer-specified coolants for every make and model — such as G13, HOAT, OAT, or OEM-branded formulations. The right coolant protects your engine from corrosion, maintains the proper temperature range, and ensures compatibility with aluminum and composite components.
Why does my car overheat even though it has coolant?
Overheating can occur for many reasons — including a failed thermostat, weak water pump, clogged radiator, air pockets, or a non-functioning cooling fan. Our ASE-certified technicians perform pressure testing and system diagnostics to identify the exact cause.
Can you service hybrid or plug-in hybrid cooling systems?
Yes — we’re trained to handle hybrid and plug-in hybrid cooling systems, which often include additional circuits for batteries and electric components. These systems require specialized knowledge and OEM-approved coolants for proper operation.
Why should I bring my vehicle to Hash Imports for cooling system service?
