Check Coolant Level

Make sure that your coolant level is within the “safe” range for your car. If it’s low, fill it up with water/coolant mixture right away. You also want to check whether there are any leaks in the system. If you notice any, fix them immediately because they can cause further damage to your engine and other parts of your car.

Turn on Your Car and Open Hood

Once all repairs have been made, turn on your car and open the hood. Make sure that you’re wearing gloves at all times so as not to get burned by hot surfaces or liquids. Also, make sure that there are no flames or sparks near the engine compartment so that they don’t set fire to anything while you’re working on it.
