Peterbilt is an iconic American brand of heavy-duty and medium-duty commercial trucks, especially famous on highways and in long-haul freight. They’re known for durability, customization, and a long legacy in trucking culture.
Peterbilt is a staple of North American trucking culture, often featured in media and admired by truck enthusiasts for their classic long nose look and performance on the road. The brand also has a strong dealer and service network across North America.
A Dura-Lite™ replacement radiator is the core of your engine’s cooling system; it removes heat from engine coolant so your Peterbilt diesel engine stays at safe operating temperatures. Heavy-duty rigs like Peterbilt use large radiators designed for high heat loads and long highway runs.
What They Do:
- Cool the engine coolant using airflow through the grill and fan.
- Prevent overheating under heavy haul or idling.
- Maintain stable operating temperatures for engine and turbo systems.
379 Peterbilt Radiator
The Peterbilt 379 has an absolute legend status in the trucking world. It was built from 1987 to 2007.
Why it’s famous:
- Classic long-hood design – the stretched nose + square headlights = timeless.
- Built for customization – chrome for days, stretched frames, show trucks, you name it.
- Aluminum cab – lighter, rust-resistant, and tough.
- Old-school + muscle – looks mean and pulls hard.
What It Was Built For:
- Long-haul freight.
- Heavy haul.
- Owner-operators who wanted power, style, and personality.
- This wasn’t a “fleet special” truck – it was a statement.
A Dura-Lite radiator for a Peterbilt 379 is a robust aftermarket replacement radiator designed specifically to cool heavy-duty diesel engines (common in big trucks like the 379). Dura-Lite radiators are built stronger than many factory units and typically offer better cooling performance and durability – ideal if you’re replacing an old or damaged radiator.
