Started last night, bit concerned as we are going on a 1000 mile trip next week, does anyone have any ideas what it is please.

Doesnt seem to get louder if I rev car just stays same, no difference on dipping clutch, exhaust looks firm.

Thanks for any help.

I'm not sure if I can pinpoint the noise you refer at (low rumble) but you are there and you can locate the source of the noise by touching various parts that might be loose (oil cap, body parts, etc.) or by using a long screwdriver to touch various places and listen with your ear against its handle.

Thanks RicardoM, we have now listened with a screwdriver, which confirmed noise appears to be strongest by alternator though it is being picked up all over the engine!

We then took the belt off and the noise disapeared. So hopefully it is the alternator (and not the water pump or crankshaft end bearing!)

New alternator has been ordered.

The price of these seems to vary a lot I would expect new to be dearer than remanufactured which in turn would be more than refurbished  but that is not always the case and sometimes the descriptions are not clear as to what is being provided.

Also it appears that there could be one of 3 different sizes fitted to this engine, thankfully we could decipher the one we have (443113516751 Magneton 55amp) and have found a claimed equivalent apprently new for a very good price, hope it is OK!

I am not sure what "sizes" you are referring to. Alternators on Felicia are different in maximum current (55A, 70A, 90A) and pulley type (no. of grooves) . A 70 A alternator is a better alternative.

 

As for the source of noise, I would have checked for play in the pulleys of alternator and coolant pump instead of buying new parts. Where I come from you don't buy a new alternator for a wobbling pulley or for a worn key lock.

Alternator changed and sound gone, play in end bearing, beyond my technical ability to change but will keep as a spare.
