Frightening Sounds from Under Your Hood - Beck's Auto Center | Lafayette

Frightening Sounds from Under Your Hood

With Halloween arriving next week, we are reminded of those noises that go bump in the night and scary howls that make the hair stand up on the back of our necks.  These same sounds can be just as frightening when they come from under the hood of your car.

Check Out Those Scary Sounds

Screeching, squealing noises emanating from your car, truck or SUV normally indicate that you have problems with an automotive belt or bearing.  These sounds are a result of friction that leads to excessive wear.  These high pitched noises should be checked out if they continue to occur on a regular basis.

A Broken Belt Can Leave You Stranded

Most vehicles are equipped with a one main serpentine belt that routes around the entire pulley system. If your serpentine belt breaks it will cause your alternator, water pump, power steering and air conditioning to stop working.  Older cars use V-belts for various accessories and failure of this belt can also lead to roadside breakdowns.

Always check serpentine and V-belts for looseness and their overall condition. Replace V-belts when cracked, frayed, glazed or showing signs of excessive wear.  Noise in the belt system is a sign of wear and the smell of burnt rubber can indicate a slipping belt.

Tensioners and pulleys used in conjunction with serpentine belt systems wear at the same rate as the belt and should be inspected at the same time.

Don’t Ignore Noisy Bearings

Bearings are a critical component of several major vehicle systems including your water and fuel pumps, air conditioner compressor and wheels.  When you start to hear high pitched sounds or a loud humming noise, it’s time to figure out where that noise is coming from.  Having any of these major components fail can leave your stranded.

Routine Maintenance Identifies Problems Early

Typical serpentine belt replacement is 60,000 to 90,000 miles. Typical V-belt replacement is 40,000 to 50,000 miles.  Having a professional inspect your belts and hoses regularly will catch worn or damaged automotive belts before they cause bigger problems later.   A technician is also more likely to hear “noises” that indicate that bearings are going bad and need to be replaced.
