Solution
1. Preparation
  • Tools Required: Safety gloves, safety goggles, flashlight, OBD-II scanner.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to ensure safety while inspecting electrical components.
2. Inspect the Engine Bay
  • Open the hood and visually inspect for any signs of leaks around hoses, gaskets, and seals.
  • Check for any burnt wires or rubber, and smell around the alternator and belts.
  • If leaks are found, identify the source and proceed to replace any damaged components.
3. Check the Coolant System
  • Inspect the coolant reservoir and radiator for leaks.
  • If coolant is low, top it up with the appropriate mixture (50/50 water and antifreeze).
  • If leaks are detected, replace the faulty hoses or radiator.
4. Examine the Exhaust System
  • Inspect the exhaust pipes and muffler for rust, holes, or loose connections.
  • If a leak is found, replace the damaged section of the exhaust.
  • Use exhaust sealant if necessary for minor leaks.
5. Assess the Electrical System
  • Inspect battery terminals for corrosion and clean them if necessary.
  • Check the wiring harness for any signs of wear or damage.
  • Replace any corroded or damaged connectors.
6. Clean the Cabin Air Filter
  • Remove the cabin air filter and inspect for dirt or debris.
  • Replace the cabin air filter if it is clogged or dirty.
  • Ensure the ventilation system is clear of obstructions.
