The primary purpose of a radiator in a semi truck is to dissipate heat generated by the engine during combustion. Coolant, which is a mixture of water and antifreeze, circulates through the engine and the radiator. The coolant absorbs heat from the engine and carries it to the radiator, where it releases the heat before returning to the engine to repeat the process.

Semi trucks are equipped with cooling fans to enhance heat dissipation. The fan helps maintain airflow through the radiator, especially when the truck is stationary, or operating at low speeds or in a high ambient temperature. Find out more...
