Solution

1. Preparation

Tools Required: Gloves, safety goggles, OBD-II scanner, flashlight, rags.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Address Fluid Leaks

Locate the Source: If leaks are found, identify the fluid type (coolant, oil, etc.).
Repair or Replace: Depending on the fluid, repair any damaged hoses or seals, or replace leaking components.

3. Replace Cabin Air Filter (if necessary)

Remove Glove Compartment: Open the glove box and remove any contents. Detach the stops on either side to allow it to drop down.
Access Filter Compartment: Locate the cabin air filter housing, typically behind the glove compartment.
Replace Filter: Remove the old filter and insert a new one, ensuring the airflow direction is correct.

4. Flush and Replace Coolant (if contaminated)

Drain Old Coolant: Locate the drain valve on the radiator and drain the coolant into a container.
Flush System: Use a radiator flush solution as per manufacturer instructions to clean the system.
Refill with New Coolant: Close the drain valve, and refill the system with new coolant, ensuring the correct mixture (usually 50/50 with water).

5. Inspect and Repair Electrical Components

Visual Inspection: Examine wires and connectors in the engine bay for signs of damage or wear.
Replace Damaged Parts: Repair or replace any burnt or damaged wires and connectors.
