One of my vehicles started making a rather disturbing sound so I went to investigate and to hopefully fix it.

Without a general description of what the noice sounds like, squeal as compared to knocking, it is impossible to help you. Engines make a lot of different noises, so try and help by describing noise. I would suspect it is belt related, or tension pulley related as these are RPM variable noises, belts tend to slip when you accelerate and can be quite loud with a serpentine belt as example.

Hello, it's probably not safe to drive, noises are never good news, I would suggest that you check the engine oil and if it's low add oil to it and hope it's not too late to prevent engine damage.

put oil in it

When the fault diagnosis for engine noise is too big, should first eliminate noise caused by the attachment, such as produced by air compressor and the power device, don't put these mistaken for the noise of the engine noise. Remove the accessory drive belt to eliminate noise caused by these devices. Noise will spread to those who have no problem on metal parts. So use the stethoscope will help determine the position of the engine noise.help you diagnostic tool
