1. Preparation

Gather Tools: OBD-II scanner, socket set, multimeter, flashlight.
Safety Precautions: Ensure the vehicle is parked on a level surface and the engine is cool. Disconnect the battery if working on electrical components.

2. Replace Cabin Air Filter

Remove Glove Box: Open the glove box and remove any items. Locate and unfasten the stops to allow it to drop down.
Access Cabin Filter: Find the cabin air filter cover, unclip it, and remove the old filter.
Install New Filter: Place the new filter in the correct orientation and reattach the cover. Reinstall the glove box.

3. Fix Coolant Leaks

Inspect Hoses and Connections: Check all hoses connected to the radiator and engine for cracks or loose fittings.
Replace Faulty Components: If any leaks are found, replace the damaged hoses or the coolant reservoir.
Refill Coolant: Fill the system with the appropriate type of coolant as specified in the owner’s manual.

4. Address Electrical Issues

Check Wiring: Inspect wiring harnesses for any signs of damage or burnt areas. Use a multimeter to test for continuity.
Replace Damaged Wires: If any damaged wires are found, cut and replace them using appropriate connectors and heat shrink tubing.
