Dura-Lite™ is a well-known and respected supplier of Big Truck Radiators. With over three decades in the heavy-duty radiator market, our products are rugged, tried and tested, and will deliver the reliability sought by all truck owners.

Our radiators contain construction features that are not available on most OEM products:

• Stronger fiber-reinforced tanks to prevent stress cracking.
• Reinforced headers and extra header-stiffening plate to reduce leaks between tank, header, and tubes.
• Higher-efficiency core design, heavier gauge tubes, and improved cooling capacity.

We offer different types of radiator construction:

• Plastic Tank/ Aluminum Core Radiators (used on most newer applications).
• Steel Tank/ Copper Brass Core Radiators (for older and industrial applications).

Heavy Duty Radiators

A heavy-duty truck radiator is one of the most critical components in a commercial vehicle cooling system. It protects the engine, transmission, and turbo system from destructive heat.

Dura-Lite Heavy-Duty Radiators are expressly made for heavy-duty applications: large trucks, buses, coaches, motorhomes, and industrial/ agricultural equipment.

Our radiators are premium heavy-duty replacements that have enhanced durability features over standard OEM replacements.

They are designed to survive harsh operating conditions. These upgraded designs mean your truck with a Dura-Lite Heavy-Duty Radiator installed can handle:

• Rough roads.
• Wide engine torque fluctuations.
• Ambient temperature swings.
• Continuous full-load operation, without leaking or cracking.

Heavy Duty Radiator Replacement

If you need a Heavy-Duty Radiator replacement, we recommend you follow these steps:

• Identify your exact truck: Make, Model, and Year.
• Go to the Dura-Lite's Radiator Catalog and search for the correct Dura-Lite part number using the OEM part number or the Make, Model, and Year. The OEM part number is always the most accurate way to search for the correct cross reference to a Dura-Lite part number.
• Compare material/ construction options (Plastic Tank/ Aluminum vs. Steel Tank/ Copper Brass) based on the OEM radiator in your application.
• Check availability of inventory and shipping options.
• Review warranty terms and installation instructions (heavy-duty radiators are large, require careful mounting, flow checks, and coolant system air bleed).
• Place your order online.
• After installation, monitor coolant temperatures, check for any leaks, and ensure the radiator is performing as expected.

Semi Truck Radiators

What are the consequences of the failure of your Semi Truck Radiator?

Immediate Consequences - Overheating:

• The radiator’s main job is to dissipate heat from the engine coolant.
• A leak lowers coolant levels, meaning less fluid to absorb and transfer heat.
• Result: The engine overheats, sometimes within minutes under load or climbing a steep hill.

Symptoms:

• Rising temperature gauge.
• Coolant warning light.
• Steam coming from under the hood.
• Loss of power as the ECM (Engine Control Module) derates to protect the engine.

Risks Engine Damage - If a Radiator Leak Goes Unchecked:

• Head gasket failure from overheating pressure spikes.
• Warped cylinder heads due to uneven heat expansion.
• Cracked engine block or liners (in extreme overheating).
• Oil contamination (coolant leaking into oil circuits).
• A single overheating incident can cost several thousand dollars in engine repairs on a modern heavy-duty diesel.

Electrical and System Effects - Sensor Errors and ECM Shutdowns:

• The ECM detects high temperature or low coolant and triggers derate or shutdown modes to protect the engine.
• On some trucks, this may occur automatically and leave you stranded.

Turbocharger Impact:

• An overheated engine can lead to higher exhaust gas temperatures, affecting the turbo and charge air cooler (CAC).
• Continuous overheating shortens turbo life dramatically.

Operational and Economic Consequences:

Don’t allow a leaking Semi Truck Radiator to impact your business, install a Dura-Lite replacement for ongoing reliability and peace of mind.
