Hi Ronnie
I am tempted to try running the compressor off an electric motor. This could possibly make the install easier.... I will investigate and see if it will be possible. I will however pop in to see yours up close and personal. Going to RBM without an air-con is not on the cards. I dont care if I already have 1/4 light windows :-)

Hi Vincent
The air cons which Ventz has will be complete kits, down to the last nut and bolt. The installation will be easy. The Quarter light windows are no substitute.

Hi All. Since fitting the Weber I have been not been able to get my solenoid to work on the carb to lift the revs when the compressor cuts in. I could get it to work but it was not consistent with the revs either too high or too low. I have now got it working nicely by fitting it to operate inside on the top of the pedal.

So now it will work no matter which carb you use ??

Hi Ronnie / Vincent
To my mind the the only hope of installing an aircon successfully in a Lada in South Africa ,depends on the success between the two of you - and this might be the last chance ever to get a success story in this regard on record.
Without a positive attitude about aircons fitted to Ladas, nobody on this planet will ever succeed in this regard - I think the initial Importers of Ladas were simply too much interested in making money - and simply failed badly to investigate successful aircon installations.
So I think all eyes are focused on the two of you now.

A guy at a ac shop reccomend I build my own ac and use a small compressor from one of the newer small engined cars.

Hi Danie
I am very satisfied with the performance of my air con. It works very nice. I have an issue with the engine temperature though, and I should maybe wait to see if the radiator ever boils. It has never done so but I have that niggle at the back of my mind. If there was a problem I think a tropical radiator would sort it out. There is also the possibility that the temp guage is out and is fooling me.

Hi Charles
There is no issue with the motor driving the compressor, it does so with ease.If you were to build one yourself you would need to search the scrap yards like me to try to get the pipe work. I phoned 2 places in Durban for prices to have the flexible pipes made and was Quoted R2500. I think you would get a shock when you add all the parts together. I paid R300 at the scrap yard for the 2 flexibles. The initial quotes for the thermostat was R380 and after searching around I got it for R80. You require many parts to make up a system.

Hi Danie
The only problem I have not solved in a manner that would be available to other owners is the idle up method. I was promised an universal one from Crisp Air in Durban, but I eventually gave up trying to get it. The solenoid I used is from a 60`s MK2 jag and even though it works fine it is a bit overboard in size and even if it was still available would probably cost R1000. I have had this one for years. Someone who works with air cons would I am sure have a simple answer.

Hi Ronnie
Would it not be worthwhile to experiment with an additional bypass fuel line which should reduce fuel flow / pressure to the Solenoid ?

Hi All Wasn't Ventz selling complete ac units a while back?? These where Lada specific if my memory serves me correctly. Although I cannot remember pricing and am battling to find the details. Congrats Ronnie on pulling the ac project off. You're a star. All these projects and little mods you do, have really benefited this forum and I would like to thank you for all the trouble you go to. ................ Maybe you should start patenting them........ joke...... we'll all be heavily out of pocket!.............. forget I ever mentioned it. Sorry Guys!!! Once again, thank you, Ronnie. Regards Des

Hi Danie
The solenoid is purely mechanical and does not interfere with the fuel supply. A genuine one is very small and works on the carb linkage to lift the revs enough to compensate for the load of the compressor and is adjustable the same as the normal idle speed. What I have made is not so sophisticated but does the same thing.

Hi Des
Yes Ventz has kits available which were either R6500 or R6000 can`t remember which. That is a brilliant price for any one looking for one. I don`t know who made them but would guess it was Crisp Air. Originally the air vents were under the Radio,but I found the duct to get there chocked the flow of air and modified Ari`s to the way you see it today. The air at the 2 vents is 4 deg so it cools nicely.

Hi Ronnie
I seem to have misread your earlier post slightly.
I now assume you have managed to sort the idling problem completely - and that your aircon works 100% without slowing the revs down at idling speed ??
If so, you definately deserve "President" status at this Forum !

Hi Danie
Yes, I can set the idle speed so that when the compressor cuts in the idle speed does not change. As Ari correctly noted it will now be adjustable no matter which carburettor is fitted.

Well well well - that just proves that some of the Suppliers never really tried to install an aircon successfully in a Lada !
To my mind things like this makes this Forum very special - and proves that the Supplier's advice should not always be seen as definate facts.
Anyway - well done Ronnie, your persistence in this regard really needs to be applauded !
Maybe it would be wise to install a bigger aftermarket Radiator as well ?
Danie.

Hi Danie
Thanks for the compliments, fortunately I have more time to play around than most of our members. Yes I think a bigger radiator would be a good idea. But first I want to fit an original thermostat.
Ronnie
PS Why the local suppliers could not fit an Idle up is beyond me, as they have access to parts easier than me and the proper ones are available.

Sorry to interupt your conversation guys but i was wondering if anyone over that side of the pond could tell me if a Lada 1600 duell crank pulley would fit on a Fiat 125 1600 crankshaft as i am thinking of instaling a Aircon in my Twin cam Niva before our next Summer hits us .All repies greatly appreciated Thank you ,Cheers Trev.

Hi Trev
I have never seen a Lada 1600 duell pulley before, but I presume the duell Lada pulleys will also be "V belt" pulleys - like the pulleys on all other Ladas.
While the Fiat 125 engines require grooved belts to drive both Camshafts, a duell Lada V -belt crankshaft pulley will not work on the Fiat engine .
If the Lada 1600 crankshaft pulleys are indeed grooved, I do not know whether it will fit on the Fiat crankshafts.

Hi Trev Can`t answer your question as I do not know. If you have space and the design allows it here is another way to do it. Make sure your compressor has a double pulley and you can move the alternator forward just enough to drive it from the front pulley. Ronnie Attachments:

I thought we were talking about a drive belt, or are we talking about a cam belt?.

Hi Trev / Ronnie
I initially thought that the grooved (toothed) crankshaft pulley at the back, (which drives the two camshafts) and the V pulley right next to it, (which drives the waterpump and alternator) is a complete unit.
After I have cleaned the pulleys properly just now, I realize that the pulleys are indeed two separate units - so there is a possibility that the 1600 Lada pulley (or another pulley) could be fitted to drive an aircon pump.

Hi Danie
The way this A/C of mine is driven is the existing crankshaft pulley now drives the water pump and the A/C compressor and the double pulley on the compressor drives the alternator. This would also be an option on the Fiat where you do not need to look for a double pulley for the crankshaft.

Hello Guys,Many thanks to all those who have replied to my post today .I apreciate all your efforts very much .And yes Danie you are right as i forgot to mention that the ribbed pulley for the cam wheel drives is separate from the v belt pulley that drives water pump and alternator .That is why i was asking if anyone knew weather the double Lada belt pulley would fit on the Fiat crankshaft thanks again ,Cheers Trev .

Hi Ronnie / Trev
Ronnie, your idea sounds like a perfect solution.
Trev, it might be much easier to fit a dual pulley to the compressor, as duell pulleys can easily been fabricated by any reputable engineering company - if not available elsewhere.
