How often should I flush my coolant?

Most manufacturers recommend a coolant flush every 30,000-50,000 miles or every 3-5 years, whichever comes first. However, some long-life coolants can go up to 100,000 miles. We follow your specific manufacturer's recommendation and test your coolant condition to determine if it is due for replacement.

Why is my car overheating?

Common causes include low coolant from a leak, a failed thermostat stuck closed, a water pump that is not circulating coolant, a clogged radiator, failed cooling fans, or a blown head gasket allowing combustion gases into the cooling system. We diagnose the exact cause before recommending repairs.

How much does radiator repair cost?

Radiator replacement ranges from $400-800 for domestic vehicles and $600-1,500 for European and luxury vehicles depending on the specific application. Water pump replacement runs $300-1,200. We provide detailed quotes before starting any work.

Can you fix a heater core?

Yes. Heater core replacement is labor-intensive because the dashboard must be partially or fully removed in most vehicles. We handle heater core replacement for all makes and models, including European vehicles where this repair can be particularly complex.

What coolant does my European car need?

European vehicles require specific coolant formulations — BMW uses a blue-tinted coolant, VW and Audi use G12 or G13 (pink or purple), Mercedes uses a specific MB-approved formula. Using the wrong coolant causes corrosion, water pump seal failure, and cooling system damage. We always use the correct specification.

Do you service performance vehicle cooling systems?

Absolutely. Performance and track vehicles often need cooling system upgrades including larger radiators, oil coolers, and auxiliary cooling circuits. We service factory cooling systems and install performance cooling upgrades for vehicles used in spirited driving or track days.

Signs of Cooling System Problems

Cooling system failures are one of the leading causes of roadside breakdowns and engine damage. A small coolant leak today can become a blown head gasket tomorrow. Overheating even once can warp cylinder heads and destroy engines. Catching cooling system issues early saves thousands in repair costs and prevents being stranded on the side of I-65 or I-64 in the middle of summer.
