When the engine is cold and I'm in Drive or Reverse with my foot on the brake I'm getting a chirping sound as if the belt is slipping.
When the engine is warmed up it's fine.
The belt looks OK, not perished etc
Any idea guys ? Could this be Alternator Clutch Pulley ?

Thanks ;)
 
I have the same problem after having changed the belt, idler pulley and tensioner with after market parts and now not sure if it is the water pump squeaking or the tensioner spring/rubber. Goes away when warm:dk:
 
Not sure if this helps anyone shed any light - The noise seems to appear more when the engine is cold but we have hot weather :dk:
 
It's been great over Winter, the warm weather is back & so is the chirping/slipping noise ? :confused:
