The coolant cooler is the most important component of a cooling module. It consists of a cooler core and water tank with all the necessary connections and attachment elements. The heat generated by combustion in the engine is absorbed by the coolant and discharged to the outside air via the cooler. Coolant coolers a installed in the air flow of the vehicle's front end.
You can easily find our online catalog concept. You can thus for example enter the respective vehicle via our comprehensive manufacturer list, its type designation or the engine code.

With our catalog app, you can easily and quickly find HELLA products for passenger and commercial vehicles. The intuitive user prompting will lead you to the right result in a few steps -- totally easy and straightforward: simply choose vehicle type, brand and model and the suited HELLA products will be displayed in front of you. The results are presented clearly sorted according to assemblies and product areas. They also allow viewing additional information, images, technical data while enabling product comparisons.
The need to provide material safety data sheets is based on Directive 91/155/EEC from March 5, 1991. The data sheets are updated as soon as there is a new revised edition.
Our PREMIUM LINE video will show you all the advantages and the easy product identification.
Dissipating the heat in high-power passenger car engines requires not only high-capacity coolers, but blowers and blower drives capable of providing an efficient supply of cooling air as well. Visco® fans consist of a fan wheel and a Visco® clutch. They are used in engines installed lengthwise and are assembled in driving direction in front of the cooler.
The Visco® clutch establishes, relative to the temperature, the frictional connection to the fan wheel and impacts its speed. Via the wear-free fluid friction, the drive torque is transmitted to the fan wheel. For the electrically controlled Visco® clutch, control occurs directly via sensors. Cooling as needed optimizes the coolant temperature level, engine noise level and fuel consumption
A condenser or cooler fan consists of an electric motor with a flange-mounted fan wheel. They are mounted in front of or behind the condenser or cooler. They remove heat from the refrigerant or coolant via the generated air flow. Air-conditioned vehicles mostly use an additional or more powerful blower.
The cabin heat exchanger is located inside the vehicle cabin underneath the dashboard. The air flow produced by the cabin fan is routed through the cabin heat exchanger, which has coolant flowing through it. The air heated here is then discharged into the vehicle cabin.
