Maintaining a truck as huge as the Freightliner MT55 doesn't have to be a tough job. It is not as different as keeping a sedan in good condition. Since this truck is built for heavy-duty hauling and cargo, it is inevitable that its parts will wear out as time passes by. It is important, however, that you ensure that it is regularly maintained so that it will always perform at its best. Here are some tips and tricks that you could use to keep your Freightliner MT55 always dependable.
The secret to having a flawless engine is to ensure that you are changing your oil once every 3,000 miles. Filling up your tank with fresh oil goes a long way. It helps keep the engine working fine, and everything else follows. Just make sure to use only the brand that is recommended by your manufacturer. You can always refer to your truck's owner's manual for the list of oil brands. It is also important to check the condition of your belts with every oil change. You can replace your timing belts every 60,000 miles.
Depending on your driving habits, it is important that you take time to replace your brake pads as soon as they show symptoms of premature wear. Usually, the front brakes last 20,000 to 30,000 miles, while rear brakes last up to 60,000 miles. Their lifespan, however, varies depending on how you use your brakes. Once you see cracks on the brake pads, take it as a sign that it should be replaced soon. Driving with worn-out brake pads could be very risky. They should be changed with ceramic replacement parts immediately.
It is very important to have your truck's spark plugs checked once in a while and replaced when your car reaches 30,000 miles. While you are at it, inspect the condition of your spark plug wires as well. They should also be changed at around 60,000 miles or as soon as they go bad. This is to ensure that you will not encounter any problem starting your vehicle. Spark plugs are easy to find and cheap to replace, so don't hesitate to change your busted plugs as soon as possible.
For a vehicle as big as the Freightliner, it is essential that you practice tire rotation to ensure that the wear is being distributed to all tires. The lifespan of tires is dependent on your driving style and the weight that you usually carry in your truck. It is important to also check your tire pressure before you set out for a drive to ensure that you will not encounter a blowout while on the road.
Corrosion is always the culprit for a worn-out distributor cap and rotor. Same goes to other components that are made of metal or steel. Check your truck's caps if they are already worn out, and replace them as soon as you can. A loose or missing cap could cause leaks.
