Squealing like a pig.

That was because the alternator drive belt was slipping so I left it until I fitted the repaired alternator and it has been fine since. While I was doing that I noticed that the water pump pulley seemed wobbly and when I spun it by hand it was making a rumbling noise similar to one I've heard when Becky is ticking over. I was going to leave it because the water pump is working and there are no leaks. A mate strongly suggested that it would fail so I've ordered a brand new water pump from my trusty local motor factor which is gonna cost just over 14 pounds so it is worth doing. I just hope I can get the water pump off to be able to do the job!
