A truck radiator dissipates excess heat from the engine coolant, which absorbs heat from the engine block. Without this, the engine would overheat, risking serious damage (warped heads, cracked blocks, oil breakdown).

How It Works: Step-by-Step:

• Coolant Circulates - A water/ antifreeze mix absorbs engine heat.
• Coolant Enters Radiator - It flows through narrow tubes in the radiator core.
• Air Flows Across Fins - As the truck moves or fans engage, the outside air flows over the radiator’s finned surface drawing heat away.
• Heat Dissipates - Thin metal fins spread and radiate heat efficiently.
• Cooled Coolant Returns - The now-cooled fluid is sent back into the engine to repeat the cycle.

Why Buying a Dura-Lite Truck Radiator Matters

A diesel engine produces a huge amount of heat; the combustion temperature can be as high as 1,400°F and the heat energy that must be rejected.

An efficient radiator:

• Extends engine life.
• Prevents breakdowns.
• Saves fuel (by avoiding fan overuse).
• Maintains safe emissions.
