Cooling System Service

Overheating destroys engines. We diagnose and repair radiators, water pumps, thermostats, coolant leaks, and hoses before a small problem becomes a catastrophic one. Every repair backed by our 3-year/36,000-mile warranty.

What We Service

Keep Your Engine Running Cool

Your cooling system circulates coolant through the engine, radiator, and heater core to maintain operating temperature. When any component fails, engine damage follows quickly. We catch problems early with every digital inspection.

Cooling system service at Reflex Automotive

Radiator Service & Repair

Leaking, clogged, or damaged radiators cause overheating. We pressure test, flush, and replace radiators with OEM-quality components.

Water Pump Replacement

A failing water pump causes overheating and can lead to timing belt or chain damage on some engines. We replace water pumps and inspect the entire cooling circuit.

Thermostat & Coolant Flush

A stuck thermostat causes overheating or poor cabin heat. We replace thermostats and perform full coolant flushes with the correct manufacturer-specified coolant — not universal green fluid.

3-Year / 36,000-Mile Warranty

Every cooling system repair is backed by our warranty. OEM parts, documented service, and real accountability.

Audi & VW Cooling
European Cooling Systems Need European Expertise

Audi and VW cooling systems use plastic components that become brittle with age — water pump flanges, thermostat housings, and coolant pipes. We know which parts fail on each model and proactively inspect them during every service visit. Preventing a roadside overheat is always cheaper than repairing one.

I appreciate their thoroughness in going over my car at every appointment and presenting me with a visual and written report that helps me prioritize needs if necessary, and are always willing to talk anything through. It can be difficult to find a solid trustworthy place to service your car. Heather and her team do a great job as far as I'm concerned and have throughout my relationship with them.

FAQ

Cooling System Questions, Answered

Temperature gauge running high, coolant puddles under the car, sweet smell from the engine bay, heater blowing cold air, or a low coolant warning light. Any of these means something in the cooling system needs attention. Schedule a visit or call us at (603) 207-4004 and we'll diagnose it.
It depends on the manufacturer specification and the type of coolant. Most vehicles need a coolant flush every 3–5 years or 50,000–60,000 miles. We check coolant condition at every service visit and recommend a flush when the protection level drops.
No — mixing coolant types can cause corrosion, gel formation, and cooling system damage. Audi and VW use a specific lilac-colored G13 coolant. We always use the manufacturer-specified coolant for your vehicle.
