Mechanics check brakes by inspecting the braking system for wear, leaks, and proper operation. They test the brake response, check air pressure (for air brakes), and look at visible parts like slack adjusters or chambers. They also listen for unusual noises during operation.
Fleet management helps track maintenance, reduce downtime, and improve fuel efficiency. It also ensures your trucks meet safety and compliance standards. With proper management, you can plan repairs before breakdowns happen and extend the life of your equipment.
Yes, fixing an exhaust leak is important for safety and performance. Leaks can let harmful gases into the cab and reduce fuel efficiency. Ignoring the issue can also cause damage to nearby components or fail emissions testing.
While walk-ins are welcome, we recommend calling ahead to schedule an estimate so we can dedicate time to assess your vehicle thoroughly and answer your questions.
If the EGR valve sticks closed, exhaust gases can't recirculate, leading to higher combustion temperatures. This can cause knocking, increased emissions, and engine damage over time. It may also trigger a check engine light or lead to failed emissions tests.
Coolant usually lasts between 30,000 to 60,000 miles, depending on the type and truck manufacturer’s guidelines. Over time, coolant breaks down and loses its ability to protect against corrosion and overheating. Regular testing and flushing keep the cooling system working properly.
Replacing a drive shaft is a moderate job that depends on truck size and configuration. It usually takes a few hours, but seized bolts or custom parts can add time. A worn or unbalanced drive shaft should be addressed quickly to avoid further drivetrain issues.
