🎵 SQUEAL UNDER THE HOOD? YOUR CAR ISN’T DROPPING A NEW SINGLE!
Searching, “Why is my serpentine belt squealing?” The belt itself might not be the only problem. Possible causes include:
A worn, cracked, or glazed belt
Oil or coolant contamination
A weak automatic tensioner
A misaligned or damaged pulley
A failing idler-pulley bearing
Trouble with the alternator, A/C compressor, water pump, or another belt-driven component
Spraying on belt dressing may temporarily change the noise, but it can mask the real cause and contaminate the belt.
If the battery light appears, the temperature gauge rises, steering becomes unusually heavy, or the belt starts slapping, safely pull over and shut off the engine. Depending on the vehicle, one belt may operate several critical systems.
Let Cleveland Auto Repair determine what’s really making that squeal.
