The last time I tried starting the car[last week]it had been stood a while,as soon as it started there was a loud squeal[as you'd get from a slipping fan belt]but I had to leave it alone at that time and just turned the car off straight away.Today I've been to the garage to investigate possible causes-and also found I'd only closed the boot lid down without shutting it properly so the battery had gone flat
Took off the auxiliary belt to check if any of the pulleys were stiff/seized,the belt did seem "stuck" to a couple of the pulleys[took no effort to "unstick" them though[but could be a cause of the squeal]is there anything I can put on the belt/pulleys to stop this as it's not a problem I've ever come across before?Rotating the pulleys by hand showed no stiffness/roughness,but rocking the pulleys up/down and side to side produced a noticeable amount of movement on the aircon pulley and an audible knock when it was moved,so presumably a bearing or something is shot?Is it thought this could produce the squeal?As the aircon doesn't work and never has while I've owned it I'm minded to but a non-aircon belt for it to bypass the aircon pulley,but will delay for others opinions ideas on the squeal.
