In any case, if this noise lasts, follow these recommendations to help you find the origin.
When does my Ford C-max produce a loud noise?
One way to detect a noise from your Ford C-max is to determine when it occurs. Indeed, some problems can be linked to components that are only stressed under certain types of conditions. It is this method that we will focus on in this first part.
Loud noise Ford C-max when accelerating
Loud noise on Ford C-max that shows up when you are accelerating can be symptomatic of several failures. Indeed, if you encounter a noise that is louder and louder when you accelerate, it can come from a faulty turbo that will create a much higher noise than during normal operation. Moreover, it is also highly possible that loud noise on your Ford C-max is related to a wheel bearing, which is one of the most common causes of these types of signs of illness. Another alternative is that your exhaust pipe may have holes or a collar may have become loose. Finally, it is also possible that the problem may come from a deformed tire or an unbalanced wheel that will tend to vibrate as it increases speed.
When my Ford C-max is stopped
If your Ford C-max makes a loud noise while not accelerating, engine on, the problem may be linked to poor air intake. An air intake hose that has come loose or has a hole in it may be the induce.
Where does loud noise come from on my Ford C-max and how can I be sure of its origin?
Now that we have located the origin of the sound, we will look into the verification stage to be certain that this is the matter you are encountering.
The loud noise comes from the wheels of my Ford C-max
As we have seen earlier in this article, loud noise from the wheels of your Ford C-max may be linked to two main trouble. If it is one of your tired bearings, it will tend to make a thumping noise that intensifies when it is under stress (spins faster and faster). So remember to examine by driving “fast” (neutral gear on and window open to hear only the noise of the wheels) that the noise is located here, if this is the case swap it or them right away. If it is a deformed tire, don’t forget to visually check the entire tread area for linearity. If it is the balancing of the wheels of your Ford C-max that is the issue, you will tend to feel a vibration in the direction of the car as you go faster. In both circumstances, you will have to go to your auto mechanic to replace the tires or accomplish a balancing.
The loud noise comes from the engine of my Ford C-max
In case you have identified loud noise as coming from the engine of your Ford C-max, the two most likely causes are turbo and air intake. In the first case, a turbo failure may also be associated with a compression loss during the engine ramp-up phase, so you should experience a power loss during your acceleration. If the loud noise on your Ford C-max is related to air intake, the check will be done mainly visually, check all your air intake hoses by a visual control in your engine block to be sure that it is not damaged or disconnected which would cause an air intake, if it is just disconnected you can reconnect the air intake tubes yourself. Then examine that the engine idle speed is not random. In case you confirm one of these two disorders, take your car to your mechanic .
Loud noise comes from the exhaust pipe of the vehicle
If the noise you have recognized comes from the exhaust pipe of your Ford C-max, it is highly possible that you have rust if your automobile is old and has created holes in it over time and therefore generates a very high noise close to aircraft noise on your Ford C-max, that a part has been cut off due to wear, or, finally, that a clamp has become loose due to vibrations. To ensure this, get help from someone who will stand under the automobile while you accelerate to find the exact area of starting point of this noise. If it is a hole, you can repair it with a putty provided for this purpose, or, if it is a collar, “reattach” it. If it is cut or the hole is too big, it is better to get closer to your mechanic.
