How to Remove the Nissan Tiida Evaporator?
3 Answers
Steps to remove the Nissan Tiida evaporator are as follows: 1. Prepare a bottle of automotive air conditioning cleaner and an air filter. Tools required: one 5.5mm socket wrench and one Phillips screwdriver. 2. Since automotive air conditioning cleaners come with instructions, focus on removing and installing the air filter and dismantling the glove box. 3. Start with the bottom two of the five screws, then proceed to the top three. It's advisable to support the glove box with your hand or leg during removal to prevent excessive force on the screw holes that could cause deformation. 4. To remove the air filter, first locate the plastic cover panel under the front passenger side. Use a 5.5mm hex socket wrench to unscrew the three screws and remove the dirty filter. Then replace the plastic cover panel and secure it with screws. Normally, the car's evaporator should be cleaned before and after summer use. However, if there are issues like mold, it's advisable to clean it earlier to ensure proper cooling. There are various methods to clean the evaporator. If opting for disassembly cleaning, it's essential to visit a professional auto repair shop due to the high cost and technical nature of the process, which could easily damage other components. DIY disassembly cleaning is not recommended.
I've disassembled the evaporator on a Nissan Tiida before. The process is quite tedious, but doing it yourself can save some money. First, you need to properly evacuate the refrigerant from the AC system using professional equipment - never release it casually as it harms the environment. Then, disconnect the power by removing the negative battery terminal to prevent short circuits. Next comes dashboard disassembly: start by removing the steering wheel lower cover, radio unit, and center console panels. The evaporator housing is located beneath the blower motor - you'll need to detach all heater hoses and wiring harness connectors. After unbolting the mounting bolts, carefully pull out the entire evaporator assembly. Inside you'll find the evaporator core; inspect it for leaks or blockages, and replace if necessary before reassembly. Finally, reassemble everything, perform vacuuming, and recharge with refrigerant. This job can easily damage your AC system if you're inexperienced - best to work in a ventilated area or have someone assist you. The whole procedure takes about 3-4 hours, so prepare your tool kit and patience.
When handling the removal of the Tiida's evaporator, I always remind others that safety comes first. The refrigerant must be properly recovered—failure to do so can harm people and damage the environment. For tools, prepare a socket wrench, flathead and Phillips screwdrivers, and hex keys. Before disassembly, clear any clutter inside the car to prevent small parts from falling in. Start by removing the lower side panel on the driver's seat side and the dashboard cover, then unscrew the fasteners and clips on the center console—avoid excessive force, as plastic parts can break easily. Disconnect the wiring harness of the AC control module and detach the heater hose connection, being careful not to spill coolant. Next, loosen the evaporator box mounting nuts and gently remove the assembly. Check the evaporator for ice buildup or unusual odors; replace it if damaged. Reassembly follows the reverse order, and before recharging refrigerant, perform a vacuum test to ensure proper sealing. Doing this yourself is time-consuming, and risks like coolant leaks may require rework. I usually advise beginners to watch video tutorials first.
