When most people think of car trouble, they think of the engine. However, other parts of your car can cause problems, too, including the heat exchanger. Read on to find out more!
The temperature gauge is rising
The role of the heat exchanger is to transfer heat from the engine to the coolant. If it's not working properly, the engine can overheat. If your temperature gauge is reading higher than usual, it could be a sign that the heat exchanger is not working correctly. Therefore, you need to monitor the temperature gauge in your car, and if it starts to rise, pull over to the side of the highway and switch off the engine. If your engine does overheat, it is important to have it checked by a mechanic as soon as possible.
There is steam rising from the bonnet
If you see steam coming rising from under the bonnet while you're driving, it's definitely time to pull over. That steam is usually a sign that the engine is overheating, which can cause all sorts of damage if not addressed immediately. So, as soon as you see steam, turn off the engine and let it cool down. Once it's cooled, you can check for leaks or blockages in the radiator or hoses. If everything looks good there, it's probably time to take it to a mechanic to have them take a look at the heat exchanger. Don't take any chances with your engine - if you see steam, pull over and get it checked out!
There is an unexplained drop in fuel efficiency
Have you felt like your car isn't running as efficiently as it used to? If you notice a reduction in fuel efficiency, it could be a sign that the heat exchanger is malfunctioning. If the heat exchanger is not transferring heat from the engine to the coolant, the engine can end up working harder than usual. This extra work will use up more fuel, which is why you might notice that you have to fill up more often. If you think there could be an issue with the heat exchanger, it's best to take the vehicle to an auto shop and have it looked at.
If you notice any of these three signs in your car, it's time to take it to an auto shop. A malfunctioning heat exchanger can cause several problems, and the sooner you get it fixed, the better.
