If you notice your car smoking under the hood and it’s also overheating there are a few potential reasons why. First it could be a radiator hose leak. The hose could be old and cracked or it could have come loose. If the hose is leaking coolant will escape and your engine will overheat. Another potential cause is a blockage in the cooling system. This could be a build-up of leaves and debris or it could be a more serious issue like a broken water pump. If your cooling system is blocked coolant can’t circulate and your engine will overheat.
If your car is smoking and overheating it’s important to get it checked out by a mechanic as soon as possible. These are just a few potential causes but only a professional will be able to diagnose the issue and make the necessary repairs.
