Cooling System Repairs in San Antonio
Overheating isn’t just annoying—it’s engine murder. Caleb’s Car Care, Mobile Diagnostics and Repair in San Antonio, comes to you for cooling system diagnostics and repairs so you don’t risk driving a failing vehicle. Engines are designed to run around 195–220°F. Once temps creep past 230°F, you’re on a fast track to warped heads, blown gaskets, and seized internals. By 250°F, it’s usually game over.
Don’t wait for a tow. If your temp needle is rising, you’re already at risk. Overheating can wreck sensors, fry your transmission, and cause thousands in damage long before it ever hits the red. Even a small leak, weak thermostat, or bad radiator cap can put your whole system in jeopardy. We fix that—properly.
FAQs
What temp is too hot for my engine?
Engines should stay under 220°F. Anything over 230°F is dangerous. If you’re pushing 250°F or higher, you’re risking engine failure.
Can I drive a short distance if my car’s overheating?
No. Even “just a mile” can warp your cylinder head or blow a gasket. Pull over, turn it off, and call us.
How do I know if I have a cooling system issue?
Watch for: temp needle rising, heater blowing cold, steam under the hood, low coolant warnings, or puddles under the vehicle. Not sure? Let’s get you started with a diagnostic—just say GO.
Do you use OEM-quality parts and is there a warranty?
Yes. We source OEM-quality parts and back every repair with a 1-year parts & labor warranty.
Is the diagnostic fee applied to repairs?
No. Diagnosis is always billed separately at $130 and is not credited toward repairs.
