Thanks for the replies guys i got the torque settings off one of my mates who owns a garage and as for the water pump/timing belt tensioning i went the lazy fooker route and didnt disturb the pump just gently prised the belt off the cam pulley and when re-fitting got the first fwe teeth on the cam pulley and turned the engine over with a ratchet until it wound itself back on! Sounds ver "cowboy" skylee but runs mint so all's good, Except of course for the bloody air lock in the water system which was a biatch to bleed

Thanks again

Carl
