Heavy-Duty Trucks: Brake, Cooling, AC & Wheel Parts

Workshops that repair Class 8 trucks such as Volvo VNL/VNM, Mack Vision/Granite and Mercedes-Benz Actros replace radiators, AC condensers and brake components that face long-haul heat, vibration and heavy braking loads. A failed cooling or braking part takes a revenue-earning truck off the road, so buyers need parts that match the engine and chassis the first time and are available on short notice. Buyers want a reliable supplier for leaks and failures, plus warranty cover on cooling parts.

• Choose truck radiators by engine displacement and model year, for example 10.8L, 11.9L and 12.8L engines on Volvo VNL/VNM and Mack Vision/Granite.
• Pick aluminum radiators with a tube-and-fin core built to handle constant vibration and long periods of high coolant temperature.
• Match truck AC condensers to the cab model and the original mounting points, because chassis layouts differ between Actros and North American trucks.
• Choose brake drums and discs for the axle rating and duty cycle, and inspect the friction surface for heat checking at every service interval.
