Maintaining your 2018 Mack TerraPro is essential for ensuring its longevity and optimal performance. Performing basic repairs can save you time and money, and help keep your vehicle in top condition. This guide provides step-by-step instructions for common repairs that you can do yourself.
Tools and Safety Precautions
Before starting any repair, gather the necessary tools and safety equipment. Always wear protective gear such as gloves and safety glasses. Ensure the vehicle is parked on a flat surface, and the engine is turned off with the keys removed.

- Reassemble the housing and secure it tightly.
Changing the Engine Oil
Regular oil changes are crucial for engine longevity. Follow these steps:
- Warm up the engine for a few minutes, then turn off and secure the vehicle.
- Place a drain pan beneath the oil pan drain plug.
- Remove the drain plug with a wrench and let the oil drain completely.
- Replace the drain plug securely.
- Remove the old oil filter using an oil filter wrench.
- Lubricate the rubber gasket of the new filter and install it.
- Refill the engine with the recommended type and amount of oil.
- Start the engine and check for leaks.

Worn brake pads can compromise safety. Here’s how to replace them:
- Loosen the lug nuts and lift the vehicle with a jack, then secure with jack stands.
- Remove the wheels.
- Locate the brake caliper and remove the caliper bolts.
- Slide out the old brake pads.
