Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical issues.

2. Identify and Fix Oil Leak

Inspect Oil Pan and Gasket:
- Remove the undercarriage cover (if applicable) using a socket set.
- Clean the area around the oil pan and inspect for cracks or damage.
Replace Oil Pan Gasket (if necessary):
- Drain the oil using an oil drain pan.
- Remove the oil pan bolts with a socket set.
- Carefully remove the oil pan and old gasket.
- Clean the mating surfaces and install a new gasket.
- Reinstall the oil pan and torque bolts to the manufacturer's specifications.

3. Address Coolant Leak

Check Radiator and Hoses:
- Inspect the radiator and hoses for cracks and corrosion.
- Replace any damaged hoses with new ones.
Replace Water Pump (if leaking):
- Drain the coolant and remove the water pump by disconnecting hoses and bolts.
- Install a new water pump and torque bolts to the specified value.
- Refill coolant and bleed the system to remove air pockets.

4. Verify Other Fluid Levels

Top off engine oil and coolant as needed.
Inspect transmission fluid level and condition by checking the dipstick.
