Thanks for your reply.
That pulley does look like a nice piece. How does the cooling sytem keep up witht he smaller pulley? The car is also used for towing sometimes. Although another two vehicle has recently been procured. (Due to it smashing a 68litre tank of gas in only 168kms while towing)
Plus we're in New Zealand. So that pulley would be nearer $150 our money by the time it's landed.
Car is still running a belt driven fan too. This must be placing quite a bit more load on the belt too. An electric fan is also on the to do list.
