Cooling System Repair
Overheating damage happens in minutes
San Diego’s warm weather and steep highway grades put immense pressure on your vehicle’s cooling components. At Auto Tech Specialists, we specialize in cooling system diagnostics, radiator repairs, water pump replacements, and complete coolant flushes. Conveniently located in Kearny Mesa, we serve drivers from Convoy St, Clairemont, Tierrasanta, and Miramar.
Key Components of Your Vehicle’s Cooling System
Your engine operates at internal temperatures exceeding 200°F. The cooling system circulates liquid coolant through engine passages to absorb heat, releasing it safely into the atmosphere through the radiator core.
- Radiator: Transfers fluid heat to the incoming outside air.
- Water Pump: Circulates coolant through the engine block, heater core, and hoses.
- Thermostat: Regulates coolant flow based on operating engine temperature.
- Cooling Fans: Pull air through the radiator fins when idling or driving at low speeds.
Comprehensive Overheating Diagnostics
A cooling system failure can stem from leaks, mechanical wear, or electrical faults. We perform cooling system pressure testing to locate pinhole hose leaks or cracked plastic radiator tanks. We also conduct chemical combustion leak tests to verify whether exhaust gases are leaking into your coolant due to a blown head gasket.

Questions
Frequently asked questions
What should I do if my car starts overheating while driving?
Safely pull over to the shoulder immediately, turn off the engine, and DO NOT open the radiator cap while the engine is hot. Call for roadside service or towing to avoid catastrophic engine block damage.
Why is my car leaking coolant?
Coolant leaks commonly originate from brittle rubber hoses, cracked plastic radiator end tanks, leaking water pump seals, or loose hose clamps.
How often should I flush my engine coolant?
Most modern vehicles require a coolant flush every 30,000 to 60,000 miles or every 3 to 5 years, as protective anti-corrosion additives in the fluid wear out over time.
What warranty comes with my repair at Auto Tech Specialists?
We back our workmanship with a 12-month/12,000-mile local warranty. As a certified NAPA AutoCare Center, qualifying repairs are also covered FREE by the NAPA AutoCare Peace of Mind Nationwide Warranty for 24 months/24,000 miles.
