Overheating Diagnostics
We pressure-test, scan live data, and verify the real cause — not guess and replace parts.

We pressure-test, scan live data, and verify the real cause — not guess and replace parts.
Cracked tanks, clogged cores, leaks — we restore proper cooling and airflow.
Stuck thermostat can cause overheating or poor warm-up. We replace and confirm temps.
Leaks, noise, or poor circulation — we inspect and replace pumps properly.
We find leaks fast: hoses, fittings, reservoir, heater lines — and fix them correctly.
Fans not turning on? We test relays, sensors, wiring, and fan motors.
• Temperature gauge running hot / overheating
• Coolant leak (puddle under vehicle)
• Low coolant warning or frequent top-offs
• Sweet smell (coolant) or steam from hood
• No heat / weak heat inside the cabin
• Cooling fan not turning on (or running constantly)
Common causes include coolant leaks, thermostat issues, fan problems, or water pump failure. We test to confirm the exact cause.
No — overheating can damage the engine quickly. It’s safer to stop and diagnose before it becomes expensive.
Low coolant, air trapped in the system, heater core issues, or thermostat problems can reduce cabin heat.
It depends on the vehicle and coolant type. We can check coolant condition and recommend the correct service interval.
Cooling problems don’t fix themselves. A fast inspection can prevent engine damage and keep your car reliable.
