Solution

1. Preparation

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

2. Addressing Oil Leaks

Locate any oil leaks by inspecting the oil pan, valve covers, and seals.
If leaks are found, clean the area and replace any damaged gaskets or seals.
Refill engine oil if levels are low.

3. Cooling System Inspection

Check the coolant reservoir and top off with the appropriate coolant type if low.
Inspect hoses and connections for leaks or cracks.
Replace any damaged hoses or clamps.

4. Transmission Fluid Check

Locate the transmission dipstick and remove it.
Wipe clean and reinsert, then check the fluid level.
If the fluid is low, add the manufacturer-recommended transmission fluid.
If the fluid is burnt, consider a transmission fluid change.

5. Brake System Maintenance

Inspect brake pads and rotors for wear and overheating.
If pads are worn or burnt, replace them.
Check for any sticking calipers and replace if necessary.
