Why Choose Mack?

When it comes to a strong image in the diesel world, Mack trucks take the cake. Mack has been producing medium- and heavy-duty trucks for over 100 years and has built a reputation for manufacturing high-quality trucks that can withstand harsh conditions and demanding workloads. Mack trucks are built to last, with rugged frames and heavy-duty components that can handle tough jobs.

Mack trucks also have a reputation for being fuel-efficient, which is essential for fleet managers who want to keep their operating costs low. With a range of engine options and advanced technology, Mack trucks can provide excellent fuel economy without sacrificing performance.

In addition to their durability and fuel efficiency, Mack trucks are also known for their advanced safety features. Mack's GuardDog Connect telematics system provides real-time monitoring and alerts for potential issues, helping drivers stay safe on the road. What more can you ask for?

Common Mack Issues

Despite their ruggedness, Mack trucks are still susceptible to common issues that require maintenance and repair. Some of the most common problems include air compressor failure, fuel system leaks and clogs, and coolant pressure.

Air Compressor Failure

The air system on Mack trucks is known to be prone to developing leaks. This could be due to a faulty compressor, damaged O-rings, or a bad air dryer. Additionally, like with any other manufacturer, the air filter can become blocked and cause performance issues.

Fuel System Leaks

Another issue that is common in Mack trucks is fuel system leaks and clogs—fuel lines can become cracked or blocked, and the fuel injectors can become clogged due to dirt or debris. Furthermore, fuel filters may need to be replaced periodically.

Coolant Pressure

Mack trucks have a reputation for durability and reliability, but when it comes to their coolant system, it falls short of these two characteristics. Mack trucks’ coolant systems tend to build up high pressure, and with plastic components spread throughout, leaks are commonplace.
