Bad cooling performance and refrigerant leaks are common issues that can hinder the efficient operation of automotive air conditioning systems. In this video, we use Nissan sylphy evaporator as an example to demonstrate how to replace the AC evaporator, ensuring a cooler and more comfortable temperature inside your vehicle. Learn the step-by-step process to enhance the performance of your air conditioning system and beat the heat.     First, disassemble the components below the dashboard and remove the evaporator assembly before starting to dismantle the old evaporator. The entire process requires careful handling to avoid damaging other parts, as there are many delicate components and circuits surrounding the evaporator. Each screw and connector must be removed one by one to prevent damage to other components. Once the assembly is disassembled, we can observe that the evaporator has aged due to long-term use, resulting in dirt accumulation and refrigerant leaks, which can cause unpleasant odors and inadequate cooling in the air conditioning system. Next, we proceed with the replacement of the new evaporator. Firstly, it is important to ensure that the connections and dimensions of the new and old evaporators are compatible。Then we need to check the performing of airtightness. The water leak test is a commonly used method in automotive air conditioning repair to detect potential evaporator leaks. Installing the new evaporator requires proper alignment, secure fixing, and connecting the pipelines to ensure a correct installation. When installing screws, caution should be exercised to avoid overtightening or loosening. Finally, it is necessary to check all connections and fixings for proper placement before reassembling the evaporator back into its original position. After replacing the evaporator, the outlet temperature measures 6.6 degrees Celsius (43.88 degrees Fahrenheit), compared to 13.2 degrees Celsius (55.76 degrees Fahrenheit) prior to replacement.

During transportation, product is easy to be damaged. let’s see how HBS protects its products through special cardboard box designs. Firstly, HBS selects high-quality and sturdy cardboard for its product boxes, making them more durable and robust.Secondly, to ensure safe transportation, the boxes undergo rigorous testing and design to have higher resistance to pressure and impact, ensuring that the products remain intact even after drop tests. The condenser box is designed to protect the product from compression in two ways. The coil has a triangular top, and the sides are designed with cardboard supports to prevent deformation, providing cushioning space to protect the product from damage during collisions. The evaporator box uses folded inner flaps to support and protect the coil from deformation and damage in case of collisions.      

Recently, customers provided feedback on two issues regarding the installation of quick fittings. They wanted to know how to install quick fittings correctly and how to determine if the fitting has been successfully installed. They requested assistance from HBS to resolve the issue. OK,Let's now delve into how quick fittings are installed in condensers. Firstly, let's address the proper installation of quick fittings. Customers reported that they were unable to install the fittings successfully even when pressing them directly to the bottom. Here's a handy tip: when pressing the fitting to the bottom, apply rotational force and listen for a clicking sound. This indicates a successful installation. Secondly, how to determine if the quick fitting has been installed correctly. Let's compare images of correct and incorrect installations. If the spring inside the fitting pops out, it means the installation was successful.   In summary, when using quick fittings in condensers, it is important to press the fitting to the bottom while applying rotational force. When you hear a clicking sound and see the spring inside the fitting pop out, the installation is considered successful.

Recently, HBS has received customer complaints about the core being pierced when installing the condenser connecting pipe and expansion valve. This is actually an easily solvable problem by comparing the screw length before installing the retaining plate screw. We use a Accord evaporator as an example. HBS provides 5*30mm screws for installing the connecting pipe, while customers usually have 5*36mm screws for installing the expansion valve. Before installing the pipe, compare the lengths of the connecting pipe retaining plate and the evaporator retaining plate to determine if the screw is suitable (as shown below). Using a 5*36mm screw will clearly hit the evaporator core, making it easy to puncture. However, if you use the 5*30mm screws provided by HBS, the length is appropriate and will not touch the core.   Therefore, when installing the connecting pipe, an additional step of comparing the lengths of the retaining plate and the screw can prevent it piercing the evaporator.
