TD5 Coolant leak

I have coolant dripping from the water pump housing area. I can not say for sure whether it is only the water pump.
One of the top bolts(13mm not the 8mm ones that are directly on the water pump) hidden on the turbo side, that connects the accessory drive housing to the engine, was turned out about 10mm. I turned it back in with skinned knuckles and good words, but the leak is still there. It points to the water pump, I suppose. What I am still trying to determine is, what route does the follow take from the water pump. Does it go straight into the engine through the accessory drive housing? If so, is there not a possibility that a seal or o ring or whatever seals it has also gone south due to the loose bolt? I will replace the water pump but do not want to find that there is another problem.

i dont think the bolt you mention affects the water pump in any way, its held in by the 8mm bolts in the housing. when it leaks, it comes out of the small weep hole in the side of the housing. if your seal splits (like mine did) it will gush out of the little hole at about 2000rpm. changing the pump is advised sooner rather than later. its a pig of a job just because of the stuff you have to move out of the way to get to it. if i had realised in advance, i would have done an oil change at the same time, as removing the centrifugal oil filter housing completely would make the job much easier. that involves removing the pipe connected to the sump which obviously dumps your oil. you have to remove both oil filters anyway so you might as well replace them and do an oil change at the same time.

The water flows through the accessory housing. I have been advised to remove the housing rather than removing the centrifugal oil filter housing. Water pump seem to be the culprit. Will also need the O ring that fits between the engine and the accessory housing.
I will see once I start stripping what went wrong. Thanks for the advice.

Get the "o" ring set for the pump as well, its three large O rings/seals.
