Although Mack trucks can stand up to just about anything, they are not invincible. They have parts that wear out and break, just like any other truck. These parts were not designed to last forever.

Common Problems with Mack Trucks

Some of the common repairs we see on Mack trucks include:

Exhaust Emissions

Issues with diesel particulate filters (DPF) and selective catalytic reduction systems can cause reduced performance. If the DPF is not cleaning itself properly, Consolidated Truck can clean or replace the DPF.

Turbocharger Failures

Turbochargers are constantly working; thus, they have a tendency to wear out. Once they start developing issues, you’ll notice a decrease in engine power. You may also hear a whining noise and/or see black smoke from the exhaust.

Fuel System Issues

Clogged fuel filters lead to fuel injector problems. Fuel pumps also tend to fail on Mack trucks. Fuel injector problems and clogged fuel filters cause significant power loss and could cause engine misfiring.

Cooling System Issues

Common cooling system issues include faulty thermostats, coolant leaks, and radiator fans that malfunction. As soon as you notice your Mack truck overheating, shut it down and call a tow truck. You can do extensive damage by driving it when it’s overheating.

Oil Leaks

It gets really hot under the hood of a big rig. That heat can affect gaskets and seals, including the oil pan gasket. Always watch your truck for oil leaks so you can get them repaired before you go out on your next run as if the truck leaks too much oil, it can cause the engine to seize.

Head Gasket Problems

Head gaskets are right in the thick of the heat coming from a diesel engine. That heat takes a toll on head gaskets after a while. If the engine gets hot enough, you can warp the head and do extensive damage to the engine as a whole.

Air Intake Issues

When the air filter becomes clogged or the mass airflow sensor malfunctions, it not only causes poor engine performance but can lead to other damage. If the engine is not getting enough air, it could cause the truck to run rich, which contributes to EGR issues, excessive carbon buildup, and other problems.
