andy, a quick one, why would my belt suddenly fly off the pullys as i was making a right turn, could it be the tensioner

Did it come off or shread itself? Could be your power steering pump slowing up when being asked to work hard with a full lock on  :-/ :-/ :-/ Was the belt on correctly in the first place? It's very easy to get the polly V belts a groove out between the various pullies.

Be careful getting the three pump bolts out and putting them back in. It is easy to drop them inside the cam cover casing. A bit of grease on the bolt head helps.

Ok can I ash the maybe silly questions now.

I've removed the bagpipes etc and have access to the water pump? Is it simply a case of releaseing the aux belt and then unscrewing the pump remove refit and tighten or do I need to remove other components before moving onto the coolant flush and refill stage?

Again any advice greatly appreciated.

 :)

Remove the aux belt pulley from the pump to give more access to its bolts.

No. Just put a (16mm?) ring spanner on the centre nut of the tensioner for the aux belt. The tensioner is top left looking from front. Then turn it and the whole tensioner swivels and the belt releases enough to pop it off. Perhaps useful to draw where it was routed first.

Better to ask than have a problem. i felt embarrassed asking about how to do the ABS ECU a few years back.

We all started somewhere!! Better doing the job properly yourself than paying mega bucks at a garage.

Couple of other things. When you have the belt off just give the tensioner a quick spin by hand shouldn't sound noisy. They can be removed and repacked with grease. Second thing is if you have a new pump to fit when you have attached the body to the engine, next bit is putting the pulley on. Just check that the bolts don't foul the pump body by turning it by hand. Some pumps do. You will need to either fit shorter bolts or spacers like washersso the bolts don't stick out so much. Happened to me once with a QH pump.

Big pulley right at bottem centre is crank pulley - water pump pulley directly above it - only 3 bolts hold pully on and pulley smooth not grooved

Hope that clarifies :y
