Prevent overheating before it becomes an engine replacement. Coolant flush from $150. Walk-ins welcome.
What's Included With Every Coolant Flush

We safely drain contaminated, degraded coolant from your radiator and engine block.
Flush cooling system
We run clean water and flush chemicals through to remove rust, scale, and debris.

We check radiator hoses for soft spots, cracking, and leaks at connection points.
Check thermostat operation
We verify the thermostat opens and closes at the correct engine temperature range.
Refill with correct coolant mixture
We refill with manufacturer-spec coolant at the proper 50/50 distilled water ratio.
Pressure test & concentration check
We pressure test for leaks and verify freeze/boil protection with a hydrometer.
Walk-ins welcome Mon-Sat 8:00 AM - 5:00 PM. Complete coolant flush service starts at $150.
Signs Your Coolant Needs to Be Flushed
Overheating destroys engines. Don't ignore these cooling system warning signs.
Temperature gauge running high
Engine running hotter than the normal mid-range indicates degraded coolant or a stuck thermostat.
Sweet smell from engine bay
A sweet, syrupy odor means coolant is leaking onto hot engine surfaces and burning off.
White smoke from exhaust
Coolant burning inside the combustion chamber — a serious symptom needing immediate attention.
Coolant puddle under car
Bright green, orange, or pink fluid pooling beneath the radiator or engine bay.
Heater not working
Weak or cold cabin heat often indicates low coolant or a blocked heater core.
Engine overheating
Steam from the hood or a red temperature warning — stop driving immediately to avoid engine damage.
