Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and ensure the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Identify and Repair Oil Leaks

Sub-step 1: If oil is leaking, clean the affected area with engine degreaser.
Sub-step 2: Replace any damaged components such as the oil filter or gaskets.
Sub-step 3: Tighten any loose bolts on the oil pan and filter using a socket set. Torque specifications should follow manufacturer guidelines (usually around 10-15 ft-lbs for oil pan bolts).

3. Change Engine Oil

Sub-step 1: Drain the old engine oil using an oil catch pan; remove the drain plug with a wrench.
Sub-step 2: Replace the oil filter with a new one. Lubricate the new filter's gasket with fresh oil before installation.
Sub-step 3: Refill the engine with the appropriate type and amount of oil (check owner’s manual, typically 5W-30 or similar).

4. Monitor Engine Temperature

Sub-step 1: Reconnect the battery and start the engine.
Sub-step 2: Use an infrared thermometer to monitor engine temperature during idle and while driving.
Sub-step 3: If overheating persists, inspect the coolant system for leaks and ensure the thermostat is functioning properly.
