Most of the time AC is kept ON in my 2002 Palio. One thing i have noticed, ICE, AC and headlamps are turned off the moment you turn the starter key. System is switching all these off to take care of the problem with the batteries.
Even if I start with AC on, actual ac clutch engaging sound is heard only 2-3 seconds after engine starts. I think this make sure that the starter don't have to take the load of the AC as well while starting.

I am not sure whether this is the case with other cars.

Rajesh,

You may save your engine by using the synthetic oils or whatever that helps you to save it from over revving as soon as you start it with AC ON. But its always advised to start the vehicle with as less electrical accessories 'ON' as possible. Otherwise the alternator is the one which is going to dead before the engine! You have waited till you place your key in the key hole and twist it to start the vehicle- then why cant you wait at least till the engine start to switch on the AC

1. Immediately after start
2. 1-2 Mins after start
3. 4-5 Mins after start or
4. 10 or more Mins after start.

I know, for some of us the whole drive wont be for more than 10 mins. And some of you are living in cold places where you dont need to switch on at all.

Which of these is the best to follow ? experts can pour in with their opinions please.

cheers
My vote is for 4-5 minutes normally as thats the average time I take to reach the cruising speed! I love my vehicle and never mind to sweat a bit to save the machine for bit more time!

I don't think this feature is there for all vehicles! You are lucky to get it added. My old M800 alternator winding got 'fused' as I used to start the vehicle with AC "ON" (Not intentional but forgets all the time to switch it off when I park the vehicle-Now I am careful enough with my present machine!)

On cold engine, you should avoid frequent starting as it will draw extra fuel and not good for engine as lubrication is low in cold engine.

I think most modern cars have cut off for AC/ICE while starting the car anyway. In case it is not, it is advisable to switch off everything before starting the engine.
very nice point put forward and thanks for the info

In 2001 , when Palio was launched, it had almost all the features of SWIFT launched way too later.

Junta, who took the pain to research about these features went ahead & bought one.

But Aam Junta who decides a car based on Advertisement, never knew about these as there were hardly one.

I wish FIAT must have waited for SWIFT to be launched

Default SIDEWAYS -REG your post about AC

hai.nice detail. in your given scenario how come freshair/recirculate setting affects FE ..in case if it affects? how these two setting can be applied to make the right balance between good AC/ Effective FE. TIA.

Regarding corelation between a/c blower speed and FE - Yes it does effect fule efficiency but there is a better explanation - There is a cooling coil behind the dash board just as there is in the airconditioners in your house. Compressed gas in passed thru the coil thereby dropping the temperature in the coil and the blower when switched on draws air thru a chilled cooling coil therefore provoding us with cool air. This cooling coil has a Bulb or a thermostat or a sensor. When the blower is running at a lower speed the coil gets colder faster and thus triggers the thermostat which in turn switches off the a/c compressor. When the blower runs at a higher speed the air is drawn out at a fatser rate and therefore the temperature of the cooling coil does not drop very quickly thereby running the compressor for longer periods of time. I dont know if you guys have noticed - When you take your car to an a/c mech he will always check the grill temp with blower at minimum fan speed. Notice next time you are at your local workshop.

Take care of those engines guys. They serve you better, Longer even.[/quote]

I drive my car in the morning for about a minute or two, by which time the engine temperature needle crosses the C-mark and starts crawling up. I turn the blower on as soon as I start, but the A/c has to wait till the engine is beginning to warm up.

Apologies if discussed before. Does the '4-5 minutes delayed switch on' we are discussing here apply only to AC or to ICE as well?

I am sure it does not apply to ICE. ICE does not sap the power of the engine , the AC does.

I turn on the engine, and within the next 10 seconds turn the AC on, just can't take the heat inside the car and I don't like driving with windows down, mostly due to the noise on the roads. In anycase the zen carb takes ages to cool.

Mods, sorry I'm raking up all these old threads but I find that I've not replied to many questions directed at me (which is not good according to me).

What a coincidence! In those days never knew about subscribing to reads and never saw these messages (some for me too) until today.

At 32 months and 42000+ km, the Marina's battery and the engine is holding on well.

I will at least continue this practice to see whether it would result in any problem.
