What should I do right now if my car is overheating?

Pull over safely and turn off the engine. AAA advises turning off the air conditioning and turning on the heater briefly if you cannot pull over right away. Keep passengers away from the roadway and do not touch the hood or front of the vehicle for about 20 minutes.

Do I need a tow truck, or can a mobile mechanic help at home, work or roadside?

A roadside technician can inspect the car, check coolant levels and look for visible problems like loose hoses. AAA recommends a tow if a belt, hose, water pump or radiator needs replacing. No tow truck is needed for the initial inspection in many cases.

Why is overheating urgent in South Texas?

Late April through early October, South Texas highs reach well into the 90s, and heat index values can reach 110°F or higher. Heat makes roadside overheating more urgent, and driving again can cause expensive damage.

What should I check before hiring a mobile mechanic?

Texas does not require a statewide mechanic license for general mobile mechanic work. Ask for proof of insurance and ASE credentials, which you can verify through ASE's public lookup. If refrigerant work is needed, ask for EPA Section 609 certification.

What to do next

Let the engine cool completely, and wait at least 15 minutes before adding any water or coolant. Never remove a hot radiator cap.
