Solution

1. Preparation

Gather Tools: OBD-II scanner, socket set, fluid catch pan, flashlight, rags.
Safety Precautions: Ensure the vehicle is parked on a level surface, engage the parking brake, and allow the engine to cool before beginning work.

2. Reinsert the dipstick and remove it again to check the oil level.
3. If oil is low, add the correct type of oil (refer to owner’s manual) until the level is adequate.
4. If oil appears burnt or contaminated, drain the oil using a fluid catch pan, replace the oil filter, and refill with new oil.

3. Address Transmission Fluid Issues

Inspect and Replace Transmission Fluid:
1. Locate the transmission dipstick (if applicable), remove it, and check the fluid level and condition.
2. If the fluid is low or burnt, drain the transmission fluid using a fluid catch pan.

4. Replace Worn Belts and Hoses

Inspect and Replace:
1. Visually inspect all drive belts and hoses for signs of wear and damage.
2. If any belts are frayed, cracked, or worn, use a socket set to remove the affected belt(s) and replace them with new ones.
3. Replace any damaged hoses by loosening the clamps, removing the hose, and installing a new hose with proper clamps.

5. Repair Exhaust Leaks
