If leaks are found, determine the source:
- For coolant leaks, replace any damaged hoses or components.
- For battery coolant leaks, consult a professional for battery system repairs.
Clean up any spilled fluids to prevent further chemical smells.

4. Inspect Electrical Wiring

Examine wiring harnesses in the engine compartment for signs of melting or damage.
Repair or replace any damaged wiring as necessary, ensuring connections are secure.
Use electrical tape or heat-shrink tubing to protect exposed wires.
