Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine cool.
Wear safety gloves and goggles.

2. Identify and Repair Engine Oil Leak

Locate the Leak: Inspect the engine oil pan, valve cover gasket, and oil filter for signs of oil leakage.
Replace Gasket/Seal:
- If the valve cover gasket is leaking, remove the engine cover (if applicable) and unbolt the valve cover.
- Clean the mating surfaces, install a new gasket, and reassemble.
- Torque bolts to manufacturer specifications (check service manual for specific torque values).

3. Address Coolant Leak

Locate the Source: Check the radiator, hoses, and water pump for leaks.
Replace Damaged Components:
- For a damaged hose, loosen the clamps and remove the old hose. Install a new hose, ensuring proper fitment.
- If the radiator is leaking, drain the coolant, remove the radiator, and install a new one. Ensure all connections are secure.

4. Fix Transmission Fluid Leak

Inspect Transmission Pan: Look for signs of leakage around the transmission pan gasket.
Replace Transmission Pan Gasket:
- Drain transmission fluid from the pan.
- Remove the transmission pan and clean the surfaces.
- Install a new gasket and reassemble, ensuring the pan bolts are tightened to the specified torque.
