Hello,

My Felicia 1.6 has developed a rumbling noise that has appeared over the last month from the drive belt side of the engine. Rather than trying to explain the noise I am posting two video links. The first is from last July and the second from a few days ago, and you can hear the extra noise in the second video.

 

 

 

I've recently had a new PAS pump fitted because it was leaking, but this noise was happening before the pump was fitted (I thought maybe because the pump was leaking maybe the bearing was making noise...) and is no different after fitting.

the noise only appears once the engine is warm. I've had it looked at by the mechanic who fitted the pump but he assured me everything is "tight" and nothing to worry about. The car drives ok and there isn't any noticeable loss of power etc, just an annoying noise! Any thoughts or ideas would be greatly appreciated

You can't say anything certain from the second video. I would try to listen from under the car too. Using a stethoscope or a very long screwdriver is a must to isolate the noise.

 

Thanks Ricardo, I have tried listening with a medium screwdriver at points that it can reach, I'm nervous to poke around the spinning drive belt .

so far I can only hear the noise through the screwdriver at the top motor mount on the cambelt side... But I'm not sure if that is just resonating through from somewhere else. Will probably be getting a second opinion from another mech, will post update if I do find the cause. Thanks.

Update -

 

Cause of the rattle noise has been confirmed by the mechanic to be the water pump failing.

Its now louder than in the video I posted earlier in the topic, and the mechanic said it is very close to seizing 

So its off the road for now! But fixable

Well... he is the type that likes to scare people more than necessary...

Perhaps  but the water pump has done 75000 miles, previous owner only changed cam belt and tensioner, so it does seem the likely culprit.

 

 

By the way, present part manufacturers have the bad habit of not greasing the bearing inside... If it doesn't start wining after 7,500 miles, you're lucky.
