Solution

1. Preparation

Gather Tools: OBD-II scanner, multimeter, socket set, flashlight, and safety gloves.
Safety First: Disconnect the battery before working on electrical systems and allow the engine to cool down before inspecting components.

2. Address Fluid Leaks

Locate Leaks: Identify the source of any fluid leaks found during the inspection.
Replace Seals or Hoses: If leaks are from worn seals or hoses, replace them with OEM or high-quality aftermarket parts.
Top Off Fluids: Ensure all fluids (coolant, oil, transmission fluid) are at the proper levels.

3. Repair Overheating Issues

Inspect Cooling System: Check the radiator, thermostat, and water pump for functionality.
Replace Thermostat or Water Pump: If they are faulty, replace them according to manufacturer specifications.
Flush Cooling System: Consider a cooling system flush if the fluid is dirty or contaminated.

4. Repair Electrical Problems

Inspect Wiring: Look for any frayed or damaged wires that may cause shorts.
Replace Damaged Wires: Use appropriate gauge wire to replace any damaged sections.
Check Battery and Alternator: Ensure both are functioning properly; replace if necessary.

5. Exhaust System Repair

Inspect for Damage: Look for signs of damage or loose connections in the exhaust system.
Replace Damaged Components: If any parts are found to be burnt or damaged, replace them with quality parts.
