Is Your Acura Running Hot?

If your Acura's temperature gauge is climbing or you're seeing steam under the hood, it’s time to address a potential overheating issue. Overheating can lead to serious engine damage if not resolved quickly. In this guide, we’ll explore the most common causes of overheating in Acura vehicles and which components you should check first.

1. Radiator Issues

The radiator is essential for regulating your engine's temperature. A cracked radiator, blocked fins, or a leaking hose can cause your Acura to overheat. Check for any signs of coolant leakage or debris blocking airflow.

2. Thermostat Failure

A malfunctioning thermostat can remain stuck closed, preventing coolant from circulating through the engine. This causes heat to build up rapidly. Replacing a faulty thermostat is often a quick fix for overheating.

3. Water Pump Problems

Your water pump ensures that coolant flows through the engine and radiator. If it fails, your Acura will overheat in minutes. Look for coolant leaks around the pump or unusual noises when the engine is running.

4. Coolant Level and Mixture

Low coolant levels or an incorrect water-to-antifreeze ratio can cause overheating. Always use the recommended coolant type and keep it topped off to ensure proper engine cooling.

5. Radiator Fan Malfunction

If your radiator fan isn’t turning on, your Acura may overheat when idling or driving slowly. This could be due to a blown fuse, faulty fan motor, or temperature sensor issue.

6. Clogged or Leaking Hoses

Old or damaged radiator and heater hoses can collapse or leak, reducing the efficiency of your cooling system. Inspect them for cracks, bulges, or leaks and replace as needed.

Preventative Maintenance Tips

• Regularly check and refill coolant levels.
• Flush your radiator and cooling system every 30,000 miles.
• Replace worn-out hoses and belts promptly.
• Monitor your temperature gauge for any abnormal spikes.
