Solution

1. Preparation

Gather tools and parts needed for repairs.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the negative terminal of the battery for safety.

2. Identify and Repair Oil Leak

Tools Required: Socket set, torque wrench, oil catch pan, rags
Steps:
1. Remove the engine cover if applicable to access the oil filter and drain plug.
2. Place an oil catch pan under the oil drain plug and remove the plug using the socket set.
3. Allow the oil to drain fully, then inspect the drain plug for wear or damage.
4. Replace the drain plug and torque to specifications (typically around 25-30 ft-lbs).
5. Inspect the oil filter; if it’s leaking, replace it with a new filter and ensure it is tightened properly.

3. Identify and Repair Coolant Leak

Tools Required: Socket set, coolant funnel, rags
Steps:
1. Check all coolant hoses and connections for any visible damage or looseness.
2. If a hose is damaged, remove it using the socket set and replace it with a new one.
3. Refill the coolant system using the appropriate coolant type specified by the manufacturer (typically a 50/50 mix).
4. Run the engine and monitor for leaks around the repaired areas.

4. Clean Up

Clean any spilled fluids using rags to prevent slipping hazards.
Dispose of any used oil and coolant properly according to local regulations.
