Latest edition to the family....my new baby

Does anybody have alot of experience swapping water pumps over in Mk1's, specifically the housing unit. Have researched alittle and most people recon the bolts shear when u try to remove them so just get housing aswell. Been quoted $175 for pump and housing through VW (they think it will be this price but will get back to me??  ) They want the unit to be exchanged and require my old unit to be cleaned thoroughly??

So where I'm going with this is......do the bolts shear really easily or should i wing it and try to remove it. Any advice from anyone who has done this would be handy cheers.

I've taken several off in my time, most recently off the cab when I had the engine out. I've never snapped a single bolt. I think they're M5 so will only take 40 or 50 Nm before they snap so care is required. My replacement one was a topran so not genuine but still German. A little known detail is that they were made with 2 different thicknesses of gasket which affects the clearance of the pulley to the bottom timing belt cover. The fatter one is preferrable. I doubt you've got aircon so whip the mouning bolts out and tap the housing until it cracks off. Avoid trying to lever it off unless you put something in the pipe and lever it. Dents in the sealing face on the block would be a nightmare. Good luck!

If the bolts are seized they will snap nothing you can do about it. But try first.
 Make sure you remove the whole housing from the side of the block, no need to remove the cambelt.

 Thoroughly cleaned

Cheers boys. Think i'm going to give it a shot over the weekend....will spray her up and see what happens, just take my time, will order another housing anyway tomorrow. Got a feeling I know how it'll turn out

Spraying CRC onto the waterpump bolts will make no difference at all.
 If they are going to snap they will snap, even heat made no difference to the ones I have snapped.
 The only way they come out is if like me somebody put anti seize on them when they fitted them.
