Polo 6R - How to clean the AC evaporator/cooling coil

Автокөліктер мен көлік құралдары

Here’s a detailed video showing how to easily clean your car’s AC evaporator or cooling coil. The cooling coil aids in chilling the cabin when you turn on the AC and must be kept clean from time to time. A clogged cooling coil will result in reduced cooling performance and formation of frost.
The DIY is easy, can be done at home without any complicated tools and can be wrapped up in an hour. If your car’s cooling performance has come down over time, a choked cooling coil can be one of the reasons. Check it out and do let me know if you have any comments.

    Your Polo was a bible for DIY installation. The amount of effort you put in penning down the steps was immense. Sad to hear that you had to part from it. Waiting for videos on the new car.😄

    Thanks a lot for the feedback man. Really appreciate it. 🙂👍🏻 I learnt a lot with the car and made it a point to share it with the world so others benefit it too. On the Jazz I’ve just added the OE auto-dimming mirror, new Yokohama tires in 195 width and the OE underbody shield. I haven’t started doing any videos with the Jazz but will definitely start some time. It’s a discontinued car today! 😆

    As soon as I saw the video I was very happy to see you still have the polo... I went through your ownership thread right away just to see if you have updated any in your ownership thread. Really really sad to see you parted ways with your polo. When I bought my polo tsi I used to drool at all the things you did to your car. Back then I was in 2nd year college. No money yknw. So these days I buy something every now and then for the polo with reference to your thread. Many thanks bro! Hope to see your Jazz soon :-)

    Hey so soon? I mean it just be 1-2 years since you must have got the Taigun. Do you stay and drive in a very dusty area? I understand that the new Skoda and VW cars have a low AC performance but have you got the recent update from VW/Skoda? Do check with your authorised service centre.

    @@GaneshBalan It’s been 15 months since I have got the car buddy. There is some bad odour every time I turn on the AC. Also on long drives this unpleasant smell kinda makes us uncomfortable. I mostly keep the recirculation mode off since I prefer fresh air. Only in heavy traffic I turn it on. Also We have never used any car perfumes or anything. I park my car under a shed. But yes it’s a dusty area.

    Hi, indeed I had recorded this some time back. Never had the mojo to edit and release it after I sold the car. Just lost all the motivation. But I thought I should do it since I’ve invested time and efforts in it. As regards ineffective cooling, while this is one, you should also check for other issues such as low refrigerant gas in the system, a dirty and clogged condenser coil etc. Do get the system thoroughly checked from a competent AC mechanic.

    Hi Anirudh, nope no sticky residues. The concentrate inside the can is a non-sticky type. The throw of air was smelling very pleasant as if the car just rolled out of the showroom. If your car is over 6-8 years old and if you haven’t done this before, do try it out. 🙂 You’ll be pleasantly surprised at the results.

    Hi, the heater is part of the coolant system. When the engine achieves operating temperature and the coolant temperature reaches approx 90’C, if you turn on the heater of the HVAC system, the hot coolant circulates through the vents.

  • @GaneshBalan

    9 күн бұрын

    Hi, no I could not. I wanted to but the aftermarket FNG where I used to give the Polo here in Chennai would always dissuade me by saying it is hard to access the EGR unlike the Marutis and it wont yield any tangible benefits (which I would disagree with). If your diesel Polo or Vento is over 6-8 years old, it will be worthwhile getting it cleaned. Lot of soot deposits.

    As long as the spout of the foam can reaches the evaporator coil and covers the coil with the foam, it works from the other side as well. Some folks access the coil from the cabin filter and spray the foam.

    Exactly I was wondering why to fill through vents, the dirt gets accumulated on other side of the Evaporator Coil which is far side of the vents as air gets thrown from other side. Filling through Drain Pipe makes sense and logical.

    Depends on the vehicle. Essentially you aim it towards where the airflow is coming from ( indicated on the cabin air filter and sometimes on the cover. Alternately run the system on “ outside air “ and insert a piece of tissue firmly held in your hand, into the area that the filter used to be in. You’ll be able to tell which direction the air is coming from.

    Hi, this procedure is standard and works on all cars. Just check where the evaporator drain pipe on your car is. It would most likely be in front of the firewall. If you turn on the AC for some time, you’ll see the water dripping below your car. The spot above that is where rhetorical evaporator drain pipe is situated.
