Coolant System Services in Atascadero

Your cooling system works hard to keep your engine at the proper operating temperature. Regular maintenance prevents overheating, extends component life, and catches worn parts before they fail and leave you stranded.

Cooling System Health Check

We perform a comprehensive evaluation of your entire cooling system to assess its condition. We test coolant strength and pH, check for proper thermostat operation, inspect hoses and belts for wear, and evaluate radiator and heater core flow to identify maintenance needs.

Radiator Service

Your radiator dissipates heat from the coolant to keep your engine cool. We clean clogged radiator fins, check for restricted flow, and replace radiators that can no longer effectively cool your engine.

Coolant Flush and Fill

Over time, coolant breaks down and loses its ability to protect against corrosion, freezing, and overheating. We flush your entire cooling system to remove old fluid, deposits, and contaminants, then refill with fresh manufacturer-recommended coolant.

Water Pump Inspection and Replacement

The water pump circulates coolant throughout your engine. We inspect for bearing wear, shaft play, and weep hole seepage, replacing pumps that show signs of impending failure before they strand you.

Thermostat Service

The thermostat regulates engine temperature by controlling coolant flow. We test thermostat operation and replace units that stick open or closed, ensuring your engine warms up properly and maintains ideal operating temperature.

Cooling System Hose Inspection and Replacement

Hoses deteriorate from the inside out and can burst without warning. During cooling system service, we inspect all hoses for soft spots, swelling, and hardening, replacing any that show signs of age before they fail.
