...Operation of the air-conditioning system depends on a change of the refrigerant’s state that happens in the course of pressure and temperature variations inside the AC loop. Temperature-based diagnostics of components is considered as one of the basic methods to troubleshoot the system...

...AC Servicing - system flushing To perform properly, the AC system must be clinically clean inside the loop. Refrigerant and lubricant working in high temperatures and pressures, as well as components with precise mechanisms (compressor, expansion devices), require cleanliness for optima...

...Turbocharger Fitting Instructions 93037, 93061, 93070, 93102, 93121, 93132 Model-specific fitting guide for turbo CITROEN / FIAT / FORD / MAZDA / MINI / PEUGEOT / VOLVO 1998- 1.4, 1.6, 2.0 D / DE / HDI / MZR CD / MZ CD / TDCI / JTD 8H0 - DV4TD, 8HT - DV4TD, 8HX - DV4TD, 8HZ - DV4TD, 9H...

...Condenser corrosion possible issues The condenser is placed at the front of the car and is typically attached to other heat exchangers in the engine compartment. The condenser is crucial for the AC system operation. It ensures that the refrigerant changes from a gas to a liquid form. This...

...When to replace a Receiver Dryer The receiver dryer is a filtering unit, located on the high-pressure side of the AC loop, between the condenser and the expansion valve. The receiver dryer's main role is to filter particles and debris in the AC circuit, as well as to absorb any moisture i...

...AC troubleshooting - expansion valve malfunction The expansion valve controls refrigerant flow according to evaporator temperature and the load and cooling demand of the AC system. Nissens explains the symptoms of a failing expansion valve and what steps to take in diagnosing and repair...

...Turbocharger system air leaks The turbocharger forces extra air into the engine's combustion chamber, increasing engine efficiency and power output. The turbo operates in demanding conditions, and relies on various systems in the vehicle. Regular vehicle service is of crucial importance...

...Blower Fan Troubleshooting Interior blower fans transfer warm/cold air, depending on the set temperature, from the heater/evaporator to the passenger cabin. At the same time, the blower ensures that the air conditioning is performing properly by maintaining airflow through the evaporator....

...Turbo foreign object damage The turbocharger is a highly sophisticated and fragile component. It is a turbine-driven device that forces extra air into the engine's combustion chamber, thus increasing engine efficiency and power output. The turbocharger operates in extremely demanding and...

...Climate Comfort System in New Energy Vehicles - Diagnostics Fundamentals - Nissens Experts There is more and more new energy vehicles on our roads and highways. Do these cars require a special procedure when it comes to an AC service? What’s crucial to remember when making HVAC sy...
