How to Remove the Tiida's Evaporator?
4 Answers
Tiida's evaporator removal method: 1. The evaporator is generally located inside the car's dashboard, so when inspecting or replacing the evaporator, the entire dashboard needs to be removed; 2. Remove the glove box; 3. Remove the center console and CD player; 4. Remove the saddle; 5. Remove the instrument panel; 6. Remove the two side covers of the dashboard; 7. Remove the dashboard fixing screws, and then two people work together to lift the dashboard off. Taking the 2021 Tiida as an example, its body dimensions are 4393mm in length, 1766mm in width, and 1539mm in height, with a wheelbase of 2700mm. In terms of power, the 2021 Tiida is equipped with a new HR16DE engine jointly developed by Nissan and Renault. The engine is an inline 4-cylinder with a DOHC double overhead camshaft structure incorporating CVTC technology.
As someone who frequently disassembles car air conditioning systems, removing the evaporator box of a Tiida requires patience and attention to detail. I usually start with preparations: first, turn off the engine and disconnect the negative battery terminal for safety. Then, remove the passenger-side dashboard components, such as the glove box and nearby screws. I take photos or mark each screw location with a pen to avoid mistakes during reassembly. The evaporator box is hidden behind the dashboard, so be careful not to break the small air ducts or wire connectors when removing it. If there's refrigerant in the AC system, I typically have it professionally recovered first, as leaking refrigerant is both hazardous and environmentally harmful. For tools, have a Phillips screwdriver, a small wrench, and gloves ready, and work slowly. After completion, check all connections to ensure they're tight; otherwise, the AC may leak air. The whole process takes about 2-3 hours, mainly to prevent accidental damage to interior components, making it suitable for those with some experience. Note: regular maintenance of the evaporator box can prevent blockages and odor issues.
I recently disassembled the Tiida's evaporator box myself, and as a DIY novice, it was a bit chaotic at first. I started by watching tutorial videos online, then prepared the tools: a screwdriver and a small socket set. First, I removed the side panel next to the seat and the glove compartment, making sure to note the position of each screw. The trickiest part was removing the evaporator box, which was wedged inside the dashboard—gentle prying was key to avoid damage. At one point, I forgot to disconnect the battery and nearly caused a short circuit, but insulated gloves saved the day. While cleaning the evaporator box, I found a lot of accumulated dust, so I gave it a quick wash. After reassembling everything, the AC performance improved noticeably. I’d recommend beginners bring a friend to help, just in case something drops inside the car and needs retrieving. The whole process took half a weekend, but it saved money and taught me a new skill. Key points: The evaporator box's position affects cooling efficiency; check for blockages before disassembly to avoid rework later.
From a safety perspective, I must remind everyone that removing the Tiida's evaporator is not a DIY task unless you have professional expertise. The evaporator is typically connected to a high-pressure refrigerant system, and improper handling can lead to leaks, which pose serious risks if inhaled or contacted with skin. Standard procedure involves disconnecting the battery, removing dashboard components, and locating the mounting screws—during which wiring is prone to damage. I've seen many enthusiasts force things, resulting in shattered glass or short-circuit fires—hardly worth the risk. My advice: take it directly to a repair shop. They have specialized tools and certified refrigerant recovery systems, saving time and ensuring safety. Even if you're eager to learn, consider taking a basic auto repair course to understand AC system fundamentals first. Related tip: Pay attention to unusual AC odors or reduced airflow during daily driving—early detection can prevent complex disassembly later.
