Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, flathead screwdriver, coolant, and a funnel.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace Coolant

Step 1: Open the hood and locate the coolant reservoir.
Step 2: Check the coolant level; if low, add the appropriate coolant type as specified in the owner's manual.
Step 3: Inspect the coolant for contamination. If it appears dirty or has a burnt smell, proceed to replace it.
Step 4: Drain the old coolant through the radiator drain plug into a container.
Step 5: Flush the cooling system with water until it runs clear.
Step 6: Refill the system with fresh coolant and replace the radiator cap securely.

3. Inspect and Replace Serpentine Belt

Step 1: Locate the serpentine belt and inspect it for wear, fraying, or cracks.
Step 2: If damaged, use a socket set to relieve tension on the tensioner pulley.
Step 3: Remove the old belt and install the new serpentine belt, ensuring it follows the correct routing diagram.
Step 4: Reapply tension to the tensioner pulley and check for proper installation.

4. Check and Replace Engine Oil

Step 1: Use the dipstick to check the engine oil level and condition.
Step 2: If the oil is low or dirty, drain it using an oil pan and remove the oil filter with an oil filter wrench.
Step 3: Install a new oil filter and refill the engine with the appropriate oil type as specified by the manufacturer.
