Heat exchanger - essential for engine thermal control

The radiator is placed in the front of the vehicle, often attached to other heat exchangers, such as the intercooler or condenser. 

The radiator is essential for the cooling of combustion engines. In such engines, there may be as many as 4,000 petrol explosions per minute, each generating temperatures of up to 1,500°C. The cooling liquid, which is circulating through a cooling jacket, cools the engine block, as well as pistons, valves, gaskets, rings, engine head, and other elements of the engine.

The circulating coolant receives the combustion heat. Flowing through the radiator, it exchanges the heat with atmospheric air. 

Nissens' Solution

    Perfect finish in every detail such as water tanks, connections, threads, bolts, gaskets, mounting brackets, etc. This enables a trouble-free, quick and time-saving installation.

  • First Fit

    Depending on vehicle model, everything that is needed for a proper installation is included in the product box; caps, O-rings, nuts, clamps, plugs, gaskets, circlips, bolts, fittings, screws, hose clips ... and more.

  • Alu McCord

    Light-weight and efficient construction of aluminum cores and plastic tanks, universally applied for passenger and commercial vehicle radiators.

  • 5mm

    Aluminum-plastic construction with 5 mm spaces between the tubes, increasing the cooling performance, compared to the traditional 10 mm radiators.

  • Full Alu

    Advanced radiator construction based on brazed components solely made of aluminum, without gaskets and plastic parts.

Technical Details

Water residue may block the radiator core, limiting the coolant flow. Sediments and impurities from poor quality coolants, wrong coolant mixtures, or leak stop residues will also accumulate in the radiator tubes, limiting flow and cause limited performance.

Thermostat failures cause the cooling system to perform at incorrect temperatures, resulting in insufficient performance. 

Due to the frontal placement, the radiator is particularly exposed to light mechanical damages (insects, stone chips, high-pressure water cleaning), causing leakages.  

A leaking or non-performing radiator will expose the engine to an excessive thermal overload, which can cause it to seize.
