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

Рет қаралды 29,694

Жыл бұрын

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! 😆

Hi Jnanankur, IIRC it was close to 12k back then from Aliexpress.

Hi Antony. Thanks a lot for the feedback bro. 🙂 I’m glad the videos helped in some way. I’ll badly miss the Polo, the addiction to performance of that lovely engine and the mod-ability with VW cars.

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 :-)

@GaneshBalan Жыл бұрын

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.

@easternprestige Жыл бұрын

@@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.

@GaneshBalan Жыл бұрын

Then do try cleaning this using a cooling coil foam cleaner spray. It will make a difference. Additionally, change the cabin air filter after you do this cleaning. 👍🏻

nice. very helpful. thankyou. 1 Question. Would it be better to put the filter cover back on without the filter when spraying the foam in?

@GaneshBalan 3 ай бұрын

Hi thanks. Removing the cabin air filter cover lets you see how much the foam has penetrated within the system. That’s all.

This is a great guide, Gannu. Thanks. I'll do this soon on my vento tdi as well. Couple of questions- Did you notice any sticky residue left back in the AC after this treatment? How did your AC improve after this was done?

@GaneshBalan 10 ай бұрын

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.

I get some dusting smell only when I turn on the heater. should I do this? Its a BMW 120i. I dont know if heater is part of HVAC system.

@GaneshBalan Ай бұрын

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.

Gannu Sir -- liked your attention to detail to put masking tape so save it from foam and or anything else.

Hey thanks man. Just a precautionary step to avoid the foam getting into the switches and messing with the electricals.

Ganesh bhai! Awesome man! This is the one I have been seeking for when I had the thought of how to increase the cooling on my car. Will work on asap. ❤ But, did you videotape this earlier?😊

@GaneshBalan Жыл бұрын

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.

@pakderws6485 11 ай бұрын

A question Sir: when you insert the hose from the filter hole, does it go to the right or left side of the car to reach the evaporator?

@GaneshBalan 11 ай бұрын

Back of the evaporator coil.

@Zeek800 Ай бұрын

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.

@lalacrypto1 Ай бұрын

You need to use the drain hole and spray the foam up though it in order to actually clean the system.

@GaneshBalan Ай бұрын

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.

@anilverma-un5bf 27 күн бұрын

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.

Hey Ganesh - did you ever clean the EGR and anti-shudder valve for your car? Is it worth getting done?

@GaneshBalan 2 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.

@@GaneshBalan thanks. Appreciate your taking time to respond. My car is 7 years and done about 80k, so wondering if I should have it done. I know you have done quite a lot of kms in your car so wanted to check. One other thing, the bilstein shock absorbers you fitted, were they B6, how was your experience with them?

Will this work on GMC cars?

@GaneshBalan Ай бұрын

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.

@@GaneshBalan I gave up after a couple of failed injectors that left me and family stranded. The answer from vw was the lack of extended warranty and rsa. Which irritated me. Sold for a decent price.

Sorry to hear that man. No doubt the Polo is a lovely hatchback. No other car can match up to it in terms of performance - be it in TDI or TSI guise. Glad you got a great crossover from a supremely reliable manufacturer. Wishing you loads of happiness and fuss-free ownership with the Hyryder. 🙂👍🏻
