Aygo making horrendous groaning noise on start up


Recommended Posts

Hi people, I was wondering if I could get some help with this noise my car is making

After not being used for more than two days it makes a horrible noise on start up and a rubbing of plastic smell is in the engine bay when I shut the engine off it shuts down very fast like something was putting friction on the engine 

Could it be the alternator as its started squeaking due to the band slipping?

 

Cheer guys, charlie

I had this issue - tended to go away after driving it for a few minutes. Turned out to be no oil in the engine!

That sounds like the alternator bearings or the AC pump clutch

I suspect the squeaking noise in high gears is due to the alternator belt slipping or so I have read so it could be that

The ac doesn't work so I'm not sure if that would make a difference I suspect it needs re gassing

That would've been a painful mistake haha

I have just serviced it myself and all the levels are spot on so I'm not sure if it is that

Must admit that sounds like a bearing that's gone; Belt slip is normally more of a tortured cat shrieking sound.

You say the engine slows quickly, so the belt isn't slipping plus a slipping belt is a lot higher pitch squeal, mk1 uses the alternator to tension the belt if it's over tensioned it will kill the bearings over time

use a mechanic's stethoscope or a long bar to your ear to pin point the noise, high gears means the engine is not under such a high load

or take the AUX belt off and spin the pulleys, by hand you will soon find it

 

Ah, the A/C doesn't work it could well be the A/C clutch/bearing - you can sort it out or put a shorter non A/C belt on the car
