Yeah I know there is a very similar topic just below this one but...
I have a squeak on start up only when its cold and it lasts for a few minutes. I had my belts changed in the autumn, so thought the squeak wouldn't reappear this winter. Well it has . Just wondering how I would diagnose if its a belt or pulley issue?
I tried a squirt of WD40 onto the grooved side of the belts yesterday morning, and the squeak went away after 3-4 seconds of spray on each belt. It however came back when I next started it up. I thought the WD40 would last a few days/weeks at least. Was I wrong in thinking that?
I might pop to Halfords and gets some proper silicone belt spray tomorrow.
I was also going to try the belt tensioners tomorrow, but only if I can get my hand down past the radiator.
Do I tighten (clockwise) or loosen (anti-clockwise) the nut to increase tension?
How much of a turn should I be looking at to tighten them? I know that depends on how loose they are but am I looking at a small fraction of a rotation or couple of rotations.
thanks
