Car Overheating? We Can Help.

If your car is overheating, don't continue driving - this can cause severe engine damage. Common causes of auto overheating include:

  • Low coolant or antifreeze levels from a leak
  • Bad thermostat stuck closed
  • Failing water pump not circulating coolant
  • Clogged or damaged radiator
  • Broken or malfunctioning cooling fan

Heater Core Flush & Replacement

The heater core is a small radiator-like component that provides heat to your vehicle's interior. Signs of heater core problems include:

  • - No heat or weak heat from your vents
  • - Sweet smell inside the vehicle (coolant leak)
  • - Foggy windows that won't clear
  • - Wet carpet on the passenger side floor
  • - Coolant level dropping with no visible leak

A heater core flush can sometimes restore function if the core is clogged. If the heater core is leaking or severely damaged, replacement is necessary. Our technicians will diagnose the issue and recommend the most cost-effective solution.

Coolant Flush Service

Regular coolant flushes are essential preventive maintenance. Over time, coolant breaks down and loses its ability to protect against corrosion and freezing. A complete coolant flush service includes:

  • Complete drainage of old coolant
  • Cooling system flush to remove debris
  • Inspection of hoses and connections
  • Fresh coolant fill with manufacturer-spec antifreeze
  • Pressure test to check for leaks

Radiator & Coolant Service Questions

Common questions about radiator repair, coolant flush, and cooling system service.

Most manufacturers recommend a coolant flush every 30,000 miles or every 2-3 years. However, if your coolant appears dirty, rusty, or has debris floating in it, you should have it flushed sooner. Regular coolant flushes prevent corrosion and maintain optimal cooling system performance.
Common signs include puddles of green, orange, or pink fluid under your car, a sweet smell from the engine bay, the temperature gauge running hot, visible steam from under the hood, or constantly needing to add coolant. If you notice any of these signs, have your cooling system inspected immediately.
Car overheating can be caused by low coolant levels, a stuck thermostat, a failing water pump, a clogged radiator, a broken cooling fan, or a head gasket issue. Our ASE Certified technicians use diagnostic equipment to pinpoint the exact cause and recommend the most cost-effective repair.
Heater core replacement costs vary by vehicle, typically ranging from $500-$1,500 depending on how difficult the heater core is to access. Some vehicles require extensive dashboard removal. We provide a detailed estimate before starting any work.
Symptoms of a bad thermostat include the engine overheating, the heater not working, erratic temperature gauge readings, or the engine taking too long to warm up. A stuck closed thermostat causes overheating, while a stuck open thermostat prevents the engine from reaching operating temperature.
