•Overheating engine temperature gauge

Diagnostic Steps

1
Visual Inspection: Check for any visible signs of wear or damage to rubber components such as belts and hoses.
2
Check Fluid Levels: Ensure that all fluids (engine oil, coolant, etc.) are at appropriate levels to rule out overheating issues.
3
Inspect Belts: Examine the serpentine and timing belts for fraying, cracking, or signs of slippage.
4
Scan for Error Codes: Use an OBD-II scanner to check for any active trouble codes that could indicate underlying issues.
5
Test Accessories: With the engine running, listen for unusual noises from accessories driven by the belt (e.g., alternator, power steering pump).
6
Inspect Wheel Bearings: Check the wheel bearings and brakes for excessive heat, which can also produce a burning rubber smell.
