I'm a new member seeking some advice (tried searching the forum) on my wifes 1994 Suzuki Alto with the 657cc F6a engine. It has a genuine 34,000kms on the clock having been owned by my grandmother since new before we obtained it as a run around car. Here's the story:
On occasion (and usually when cold i.e. 0 degrees or less) the car has stalled when stopped after a short drive. It can idle a bit rough and there is a noticeable change in rpm when the headlights are turned on etc. and will sometimes stall when put into gear especially when the engine is cold.
I have replaced all the spark plugs and ignition leads but the problem still occurs. Yesterday I realised that the alternator belt had a lot of flex or 'slack' in it and it has partly de-laminated. My thoughts are therefore that the slack and worn belt is causing a fluctuation in voltage to the battery and causing the above issues?
I attempted to tighten the belt yesterday as a short term fix before getting it replaced (if that is indeed the likely problem) and to get at the necessary bolt I had to remove the vacuum hose off the brake booster.
I have put it all back together (couldn't make much difference to the belt) but now the brake pedal is very hard and the brakes only work if i put a lot of force on the pedal despite having tried to bleed them through the bleed nipples on each wheel.
So my questions are:
1. Is the worn and slack alternator belt likely to be the cause of the rough idle/stalling under load?
2. how can I get the brakes to work properly again after removing the vacuum hose?
3. does anyone have or know where I can get a decent workshop manual or at least find the correct part numbers for an alternator belt and cam belt kit so I can order these? I cant seem to find any info on the net for this specific make and model of car....
Thanks for taking the time to read this long post and any assistance
