Cooling System Repair in Auburn, CA

About Our Cooling System Service

Auburn summers put extra stress on cooling systems. A small leak or a weak radiator cap can cause overheating when temperatures climb above 100 degrees. We pressure test the system to 15 PSI to find leaks in hoses, the radiator, heater core, or water pump. Coolant degrades over time and loses its ability to prevent corrosion and carry heat. If your coolant is rusty or contaminated, we recommend a full flush and refill with the correct coolant type. Some vehicles use orange Dex-Cool, others use green ethylene glycol, and newer Toyota and Honda models use pink or blue long-life coolant. Mixing types can cause problems.

Why Choose Auto Analytx

We stock thermostats, water pumps, and radiators for most makes and models. Every cooling system repair is backed by our 24-month / 24,000-mile warranty.

We walk you through the options and provide upfront pricing before starting work.

Frequently Asked Questions

How long does cooling system repair take?

A thermostat or hose replacement takes 1 to 2 hours. Radiator replacement typically takes 2 to 4 hours. Water pump replacement can take 3 to 6 hours depending on the vehicle, since some require removing the timing belt or other components to access the pump.

How much does cooling system repair cost?

Thermostat replacement ranges from $150 to $300. Radiator replacement ranges from $400 to $900. Water pump replacement ranges from $400 to $1,200 depending on the vehicle and whether the timing belt needs replacement at the same time. Call us at (530) 392-4323 for an exact quote after we diagnose your system.

Why is my car overheating?

Overheating usually means low coolant from a leak, a stuck thermostat, a failed water pump, or a clogged radiator. Sometimes the problem is a bad radiator cap, a failed cooling fan, or air trapped in the system. We pressure test the system and check coolant flow to pinpoint the cause.

How often should I flush my coolant?

Most manufacturers recommend coolant flushes every 30,000 to 60,000 miles, or every 3 to 5 years. Some newer vehicles use long-life coolant rated for 100,000 miles or more. We check coolant condition during every service and recommend a flush if the coolant is contaminated or below spec.

Can I drive with a coolant leak?

No. Driving with low coolant will overheat the engine and cause severe damage, including warped cylinder heads or a blown head gasket. If you see coolant leaking or the temperature gauge climbing, stop driving and call us for a tow or have the vehicle brought in for diagnosis.
