How Does a Truck Cooling System Work?

An engine’s cooling system is crucial to the efficient operation of heavy vehicles. It improves fuel economy, increases horsepower, enhances driver comfort, decreases emissions, and, most importantly, expands vehicle availability.

In most aftermarket parts for European trucks like DAF, IVECO, and MAN, Horton is the brand name for cooling system components such as fans, fan clutches, and fan clutch repair kits. A Melbourne firm called Norman G Clark produces Horton truck parts in Australia. Are you interested in understanding Norman G Clark Cooling Systems? Read on to learn how its cooling system works.

The Cooling System

The following Hino parts make up your truck’s engine cooling system.

  • Water Pump for Radiators
  • Water storage for cooling systems
  • Clutch fan thermostat (also known as fan drive)
  • Fan

Horton makes both the fan and the fan clutch. To put it simply, the fan clutch determines how quickly the fan rotates in response to the engine’s requirement for cooling. Therefore, the fan clutch speeds up the fan’s rotation when it gets hot.

When the fan works correctly, it regulates the flow of air to the engine, improving the cooling system’s efficiency. Increasing the effectiveness of the car’s cooling system frees up more power for the vehicle in other truck UD parts.

How A Truck’s Cooling System Functions

Most contemporary automobiles have liquid cooling systems that use coolant liquid to dissipate engine heat. Most commonly, water is used in combination with an antifreeze solution, and this liquid circulates through a network of coolant channels.

An engine’s cooling system relies on a water pump, which uses centrifugal force to move water from the radiator to the engine block. Electric water pumps are more powerful and efficient than their hydraulic predecessors.

The coolant absorbs the engine’s heat as it flows toward the thermostat. The radiator receives hot fluid from the engine via the thermostat valve, which opens at the appropriate temperature. Air moving past the tiny radiator tubes cools the antifreeze fluid inside.

The cooling fans’ airflow is variable and is affected by the vehicle’s speed. The radiator regulates a system’s ability to transmit and absorb heat. Typically, engines use one of three different types of cooling fans:

  • Moulded: This is the most widely used in both on-road and off-road settings. Moulded fans often come in one continuous piece and are composed of plastic or nylon.
  • Modular: These give consumers the most options because their central hub can hold various blade configurations.
  • Metal: You will most often see these in non-road contexts. They are lightweight and durable and may be customised to your specific cooling needs.

How Does the Cooling System Prevent Engine Damage?

A broken radiator or electric fan might disrupt air circulation. The breakdown of the Valeo cooling system is the leading cause of engine damage and failure. Avoid these automobile mishaps with a bit of preventative maintenance. If you want to know when to change the coolant, consult your nearest car technician. The correct coolant should be used at all times.


Having a professional technician check on your cooling system as part of routine maintenance or if a connected component needs servicing is the best way to ensure that it is in good working order.

As an illustration, if you need to repair the timing belt, you should also swap out the water pump. The next time one takes their car in for servicing, have the experienced mechanics inspect the cooling system thoroughly.
