Yesterday I noticed a nasty rattle at idle.
Found that the bolt that holds the idler pulley damper to the tensioning lever had gone, so the shock was swinging loose and pulley was bouncing around.
Today I removed the shock & spring and have rotated the lever enough to get a new bolt in place. (The second photo on iscaboy's post was useful. Was good to see that I could do it without removing the water pump pulley.)
As long as the thread's OK, I think I'll be able to do it without removing anything else (including the fan), although it's going to be tight and will probably involve dropping the bolt down into the engine tray a few times, as is often the way when doing something fiddly like this with cold fingers & minimal room...
My question is, how can I ensure that the replacement bolt doesn't come out again- should I put a spring washer behind the bolt head? Use Locktite on the thread? Or both?
