One or two issues!

[MTXM]

I need to purchase the water pump, any ideas what the cost as well as availability is? Where can I get it from etc. Anyone here will sell me one?

Sorry to hear about your problems and for the water pump although new replacements cannot be obtained an overhaul is possible and I used the following:
http://www.spwaterpumps.co.uk/" onclick="window.open(this.href);return false;" onclick="window.open(this.href);return false;
The service was excellent and the cost was around £100 including carriage.
With regards,

PS. The noise on my car turned out to be due to a split crankshaft-torque convertor flex plate that I hope is not your issue!
