Coolant Leak & Overheating Diagnostics

Miami & Coral Gables Cooling System Specialists

If your vehicle is losing coolant or overheating, the cause is rarely “just a hose.”
Modern cooling systems are complex and failures must be diagnosed correctly to prevent repeat breakdowns and engine damage.

We specialize in coolant leak and overheating diagnostics for drivers in Miami and Coral Gables who want the problem fixed right — not temporarily.

Common Cooling System Problems We Diagnose

  • Coolant leaks (internal or external)
  • Engine overheating or temperature spikes
  • Low coolant warnings or repeated top-offs
  • Cooling fan or control module failures
  • Water pump or thermostat faults
  • Radiator, expansion tank, or hose failures
  • Intermittent overheating in traffic or at idle

These issues require system-level testing, not guesswork.

Why Cooling System Diagnostics Matter

Cooling system failures are one of the leading causes of major engine damage.

Without proper diagnostics:

  • Leaks return after repairs
  • Overheating worsens over time
  • Engines suffer warped heads or internal damage

Our diagnostic process is designed to identify the root cause, not just the symptom.

Our Diagnostic-First Approach

We do not sell quick fixes.

Every coolant leak or overheating concern begins with:

  • Pressure and leak testing
  • Thermal and operating analysis
  • Verification of proper cooling system operation

This approach allows us to create a complete repair plan that prevents repeat failures.

Who This Service Is For

This service is ideal for owners who:

  • Plan to keep their vehicle
  • Want permanent repairs, not temporary solutions
  • Value accurate diagnostics and documentation
  • Expect professional, warranty-backed work

If you are price-shopping coolant top-offs or temporary repairs, this service is not a fit.
