The cooling fan is coming on cooling the engine. Very normal.
no
The rear of a Ford Explorer may have a grinding noise when driving, because the muffler may have came loose. The u joint may also be loose and cause a grinding noise.
If the engine running you hear the engine rev up. Describe noise, is it when in park or when driving? Does it hurt the performance of the vehicle?
if its coming as you turn it would be lack of lubricante in the cv joint or it could be the ball joint, as far as engine wise it could be your valves
Have valves adjusted.
In order to tell you that you would have to describe the noise and what the car is doing when the noise is made. Are you idling, driving, just turned the AC on? What is occurring and what is the noise? Idling and sounds worse when AC is on. Sounds like it is coming from the top of the engine. Vehicle has 120k miles
your car is making that noise because your muffler needs oil and fume
i makes a noise called oaiso and the oaiso noise is a noise of blowing in pan pipes coz the blowing is vibrating of the sides how this answeres ur question or either go to china to find out
This be a wide range of things does it make the noise when the vehicle is in park and you rev up the engine ? It could be a heat shield on the exhaust system. it does not make the noise if it is just idling....but if you press the gas it makes a noise and when ur driving it makes noise. But I had to put a flang where the header conects to the exaust cuz it was leaking and i thought that was where the noise was comin from but its still makin the noise.
There can be a slight humming noise while driving a neon. This sound could come purely from the engine to indicate that it is running.
check tension on fan belt(s)
Too involved for this little box. Check the tech section on heatertreater.net for a full analysis of the Ford system and suggested fixes.
If the RPMs in the engine increases and the speed not, the clutch may be worn out, usually it becomes noise at the same time
