Solution

1. Preparation

Ensure the vehicle is parked on a flat surface, and the engine is off and cool.
Gather necessary tools and parts.

2. Inspect and Replace Engine Oil

Tools Required: Wrench set, oil filter wrench, oil catch basin.
Remove the oil drain plug using a wrench and allow the oil to drain fully into the catch basin.
Replace the oil filter with a new one, ensuring the rubber O-ring is lubricated and seated correctly.
Reinstall the drain plug and tighten to manufacturer specifications (usually around 30 ft-lbs).
Refill the engine with the appropriate type and amount of oil (check the owner’s manual).

3. Check and Replace Coolant

Tools Required: Radiator wrench, funnel.
Inspect the coolant reservoir; if low, add the correct coolant mixture.
If there are leaks, replace damaged hoses or components as necessary.
Bleed the cooling system if air was introduced during the repair.

4. Inspect and Replace Belts and Hoses

Tools Required: Socket set, flashlight.
Visually inspect all belts and hoses for any signs of damage or wear.
If any belt or hose is frayed or cracked, replace it using a socket set to remove tensioners as needed.

5. Inspect Exhaust System

Tools Required: Jack stands, socket set.
Lift the vehicle and inspect the exhaust system for any visible leaks or damage.
Tighten any loose connections or replace any damaged sections of the exhaust.
