Im struggling with some over heating problems, on my rover v8 4.6 westfield and I've noticed that the water pump pulley is slipping, unless i tighten the belt very tight, and that i dont have much contact on the pulley, due to the belt layout.....
I am thinking might be best to get the smooth pulley surface, slightly knurled at work, to see if this helps.
But I'm also wondering if i can squeeze a tensioner in on the right hand side of the engine somehow, but to get the pulleys to line up might be difficult.
Anyone done something similar or got a good suggestion on how to fit it all in?
The current tension is set via the little rack N pinion type wheel setup on the edge of the alternator bracket, not the best i know, but the recommended setup from westfield.
