Strange rattling noise from either alternator or tensioner


Recommended Posts

I've got a 95 mk3VR6, recently started to get a strange rattling noise from the engine, close inspection shows it is coming from the alternator/tnsioner area. My bro reckons it might be a nackered bearing in the tensioner, i don't have a clue, pretty new the the VR engine.

Would anyone know what this is, how simple to fix and how muich to fix?

If you need any more details please let me know.

thanks,

right bought a new tensioner today and just fitted it, then realised that is the water pump cog that is broken and making the noise, which is also what broke the tensioner, then when the tensioner was broken it gave the water pump even more play, hence why the noise has become so so bad! Can someone please let me know how much it is to replace, and how easy. it looks like you need to jack the engine up to gain proper access to it. Not looking good!

you do have to jack the engine up/ undo the engine mount bolts but apart from that you just undo the 3 bolts, pull it out and change it

pumps only around £50 so dont give up its not that bad. might be a day of messing about with it but it not the end of the world

just the rear mount. take off the crap gaurd underneath the pulley, wheel off first mind! undo the rear mount, take the pulley off the pump while the belt is still on, belt off after loosening tensioner, and slowly lower car/raise engine til you can see the bolts. then remove and replace. should take about an hour :D
