Rattling noise engine
« on: 29 April 2017, 06:24:03 »

Hey,

So the engine is rattling or I think it's water pump, what about you? You got 100% info?

Here is a video of the sound and this video isn't mine but sounds just like the same. (The X sound)

I hope the owner or anybody else doesn't mind me linking this video here.

The higher pitch noise makes it sound more like the idle roller (top left).

+1 Applies to all the pulleys you can see :y

Waterpump play will be self evident, likewise worn bearings...

Sound only comes as engine cold. Without the belt it doesn't make any sound. The idler is new and when I heard it was bad you could hear it clearly being it but this is different.
Any of the pulleys won't make any noise when just trying to roll them with hand...

How you recognise the waterpump failure?

With belt off, spin them by hand and feel for any roughness.  Also rock them top to bottom to feel for any bearing play, also worth checking no pully bolts loose  ;)  This applies to waterpump too
