Are you getting a warning light about your engine overheating? Are you noticing smoke or steam coming from under your hood? Are you noticing some strange smells?
These are signs that your car may be running hot. This could be caused by various issues including low coolant, a malfunctioning thermostat, or a leak in the cooling system.
If this is happening, you need to stop the vehicle safely and allow it to cool. Do not drive the vehicle until it reaches a safe temperature. Driving the vehicle and allowing it to continue to overheat could cause serious engine damage. If you are checking the coolant level yourself, we would like to suggest the most caution for you. The coolant is under pressure when it is hot and can be dangerous. Coolant should only be checked when the engine is cool.
If the temperature does not correct, then have a qualified auto repair shop inspect the cooling system for any issues.
