What action should you take if your vehicle's engine is overheating?

If your vehicle's engine is overheating, the best action to take is to pull over and shut off the engine immediately. This is crucial because continuing to drive an overheated engine can lead to extensive and potentially irreparable damage. Shutting off the engine allows it to cool down safely and prevents the risk of a catastrophic failure, such as a blown head gasket or engine seizure.

Turning on the heater, while it may provide temporary relief by transferring some heat away from the engine, is not a long-term solution and may not effectively cool it enough to prevent damage. Driving faster in an attempt to reach a service station increases the risk of further overheating and could exacerbate the problem. Ignoring the warning light is dangerous, as it signals a significant issue that needs immediate attention to avoid costly repairs and ensure the safety of you and other road users.
