Dunno which bloke in hyundai finalised the design specification of AC for i20 90CC! HUH!
Its all about the mileage!!! Bigger engine, lower mileage hence lower sales figures. In a market obsessed with mileage, an under-powered a/c is the least of the worries.

Couldn't possibly agree more with your InfinteLoop that "Mango people (aam jantha)" of India are obsessed with Mileage.
I would not complain, considering the fluctuating Fuel prices in Indi-yeah !!

My brother picked up the I-gen I20 Sportz last month and I have the 2010 Getz Prime 1.3l as my drive. These are my observation comparo:

- The AC in my Bro's I20 cools just as well as it does in my Getz after a delayed park in the hot Sun, but takes may be a bit more time than it does in my Car.
- I'm not sure how, but even with 5 on board and AC running, I20 seems to pull along pretty well in City. May be the VTVT is working here.
- My Getz can putter along in 2nd gear without accelerator input & AC running in B2B traffic coz of the Torque available. I20 seems to be just as good, even with the AC on.

So I believe either Hyundai have reworked on the AC of I-gen I20 or tweaked something that has surely reduced the AC Issue of the I20 to some extent.

They could have used a bigger compressor for i20 CRDI where the mileage would not have been affected much.

I think its a good time for automobile companies to come up with the inverter compressor which would run directly from the alternator power.

What do you know, the Mahindra Reva has come up with this compressor!

Default Hyundai i10 : Disabling the Air-con Compressor?

Greetings India,

I need some advice on how to get around a problem with the air conditioner compressor on my daughters Hyundai 10 1.2 (year 2009)?

Our daughter has suffered an air conditioner compressor failure. The options are to do without the air conditioning or get it fixed. She says she never uses it here in the UK so she could easily do without the feature.

Looking on the Hyundai service site it appears that there are i10ís and 1.2 engines made with and without the air conditioner compressor fitted. The without aircon version appears to use a shorter belt with it taking a different path around the water pump. See diagrams link below.

http://s1093.photobucket.com/user/Ac...%20con%20Belts

She has contacted the local Hyundai parts dept and as expected they just say you cannot bypass the aircon compressor and have no idea about using the shorter belt run or what the shorter belt's part number is.

Can anyone perhaps give me an indication if the shorter belt is available and if so what size, specification and part number the belt is ?

Hope you can advise us ?

If you have the part number(looks like it is there on the link but both part nos. look the same) , you could source it from a local parts dealer and have it fitted.

From the diagram you posted it is possible to bypass the ac compressor and still keep your daughter's car running.

I had hoped someone on the forum worked in the Hyundai car plant and knew about the with / without aircon models and so could supply the part number. Our dealers in the UK only know the 'with aircon' belt specifications as they are the only cars imported by Hyundai.

I will just have to take off the stretch belt and see if I can accurately measure the shorter belt run.

Hi Gio!

I hope you have found a solution to the issue on your daughter's i10.

I'm sorry that no one was able to give you the part number of the shorter belt to bypass the compressor. I assume you want to bypass it because your daughter doesn't use the air-conditioner, but she requires/frequently uses the heater which is linked to the same switch.

In India, as one would expect, the air-conditioner is a standard feature on all i10s and also on all cars with the 1.2 Kappa engine (i10, i20 and the new Grand i10). So I guess no one here is really aware of a shorter belt or its part number.

As you mentioned, only someone working in Hyundai's plant or that of the belt manufacturer would know of the existence of this belt. It looks like we don't have such a person on the forum.

May I ask what went wrong with the compressor on your daughter's car?

I own a i20 magna and fed up with insufficient cooling of AC. I was shocked to see 90 cc capacity of i20 AC more than santro. I mean come on !!!!

What are the pros and cons of upgrading the AC to either 110 cc or 150 cc ?
How easy it is for the A.S.S to upgrade it?
What will be the cost involved?
Any other workarounds to increase effectiveness of AC?

Hi RSR, Thank you for your reply.

Like you, all our i10's imported into the UK come with air conditioning as standard and that was what caused the problem because I was making the car -non standard.

Sorry for the delay in replying to the forum but only got around to dealing with it yesterday and in the short term at least, I have fitted a shorter belt to give her piece of mind and me my garage back.

To confirm:- the belt is a stretch type due to the fact there is no tension adjuster on the alternator and in order to bypass the aircon compressor pulley we bought:

a) a Laser Tools 2 piece stretch belt tool (part No 4999) for £14.39 to save messing about and pinching fingers or breaking something while trying to get the new belt on.

b) a Gates 5PK898SF belt to replace the original 5PK1236SF belt £11.26

Time took less than 20 mins to do. Jack up, fit axle stand for safety, remove wheel, remove under engine / inner wing plastic panel (4 screws secure) then pull off old belt, measure expected belt run just to confirm the new belt was more or less the right length then fit using the Laser tool and reassemble remaining parts.

You ask what went wrong? well the compressor pulley was very rusty and the centre clutch assembly held on by three outer bolts seemed very loose. Not loose so as to fall off but the inner section of the pulley / clutch mechanism seemed too loose to be correct. It may be made that way but when I go under the car again I will take a photo. When you rotate the compressor pulley by hand, it felt as though a bearing was breaking up and hence the noise it produced.

Thank you for explaining how you solved the problem on your daughter's i10!

It's great you fixed it for ~ 25 pounds when the Hyundai service centre would have charged hundreds of pounds to replace the air-conditioner compressor.

From your description, it seems the compressor itself may be okay, but the pulley or clutch may have been causing the problem. Is that the case?

I think you guys in the UK/Europe are lucky that you can buy spare parts directly from the manufacturers or OEM suppliers, and even order the correct one online. I wish the automotive after market scene in India also matures to the same level. I found the Gates e-commerce site to be very useful. I guess this is one of the pages that shows the two different belts:

To be honest if only I had found the Gates web site myself, it would have saved me a lot of trouble and measuring around the proposed belt run with string to get the approx length.

You are right about the savings, we were quoted £510 inc labour for a replacement compressor, fitment and regas by a small garage and almost £1100 by a dealer. Once the winter is over, I think I will see if I can pick up a second hand compressor off a low mileage accident damaged car and fit that.

Yes, we can get parts but you have to pay for the privilege and it does not come cheap. On the other hand you have small engineering businesses that seem to be able to produce whatever you want. We have lost the 'back street' engineering firm that could make a one off component for a good price. Our garages can no longer work out from skill and experience what is wrong with the cars they work on. Not knowing they could fit a shorter belt and bypass the problem compressor was a typical example of how our garages have lost the basic skills our fathers had. Today they can do no more than plug in a diagnostic computer the set about replacing every expensive component until by chance they eventually discover the cause of the problem. By then you have a big parts and labour bill to pay.

Unhappy Hyundai i20, A/C Compressor Issue

Dear Bhpians,

My car 2009 i20s A/c was not working for quite some time, it used to cool only slightly and that too only for 5 mins or so then it just blows out air, as a result I gave the car for servicing at HMP delhi. Now it has been found out that the compressor need to be replaced and it costs around Rs 23000/-.

Please suggest if I can get the compressor back to working condition if I get it serviced in local automobile shops. Or can i get it replaced at a lower cost at these shops.

Please share your experiences/suggestions so that i can follow suit.

Thank you all before hand.

While I'm not going to rule out the compressor conking off (and hence needing replacement), I have an unpleasant feeling that the H.A.S.S. is trying to pull a fast one on this issue, to make you cough up ~ 25k rupees (including labour) unnecessarily.

Please don't give the go ahead for a compressor replacement! You need to get a second opinion from another garage (H.A.S.S. or not) and preferably, a third opinion from a reputed independent A/C specialist.

In fact, I would recommend that you straight away go to a skilled car air-conditioning specialist who has earned a positive reputation, and ask him to take a close look. You can have a look at the Team-BHP directory section to find one in your city. Or other members who have used the services of such a specialist can help you out on this one.

A car A/C refusing to cool doesn't necessarily mean the compressor needs replacement.

It can even be because of a very simple thing, like a bad relay. Or many other simpler issues when compared to a compressor replacement.

Wish you good luck in sorting this one out. Do keep this thread updated.
