Hi
I alternator pulley is starting to click and make noises when the engine is under load on tickover so I am on the lookout for either a new alternator or pulley. I am sure its not the aircon pump as i managed to get it to click with all the electrics on and the aircon but it does not start being noisy until I put the lights on with everything else

When I look them up i see 2 are available the 150 amp with a 54mm pulley & the 180 amp with the 56mm pulley. I am guessing mine is the 180 amp with the heated screen so the more expensive one?

I have tried finding a pulley but all of the ones listed are 54mm dia so not sure if you can even get a pulley for the 180 amp?

if anyone knows which one I need i would be grateful before removing it and if you can get a 56mm pulley which would save around £200

thanks

will

180 amp for the heated screen. Some future models came with the 210 amp but I think the engines were different.
