Unless you regularly examine your engine, hearing strange noises is probably your first indication that something is wrong. If something doesn’t sound right, it’s probably a good idea to try and check it out for yourself. Here are some of the most common sounds you don’t want to hear from your diesel engine and some of the most typical causes to investigate.
Clicking Sounds
If you ever hear a clicking sound coming from your diesel engine, it might just mean that you’re low on oil, which is easy enough to check. If you’re a little low, we suggest topping off your oil, but it may also be a good idea to investigate if your engine has any leaks or unusual circumstances making it low. Fortunately, diesel engines are easy to work on, so investigating your engine for oil leaks shouldn’t be too difficult.
Grinding Sounds
Grinding is always an unpleasant sound, but the cause may be easier to identify if you listen for when the grinding occurs. If you hear it when putting pressure on your brakes, you likely need new brake pads as the old ones may have worn out. The problem may be with your suspension if you hear the grinding when turning. Grinding is a sound you don’t want to hear from your diesel engine, and if it’s occurring when you’re in an idle position, you may have worn out your bearings.
Squealing Sounds
A loud squeal is never a good sign, no matter where you are or what you’re doing. One of the most common causes of a squealing sound is a heavy strain on your engine’s serpentine belt. Given how essential this piece is to your alternator, squealing is one sound you don’t want to ignore.
If you hear any peculiar sounds from your engine, it’s always better to err on the side of caution and examine your engine or take your vehicle to a professional. Catching potential problems early on may save you from some costly repairs down the road.
