Help - water pump is stuck on!

Hi, Please help, if you can.
I have a 1997 316i. I am trying to remove the water pump. I have removed the 4 bolts 1 utilises and allen key. I initally tapped it with a hammer to loosen it - no luck.
I sprayed releasant on it, left it for more than an hour. 'Attacked' with the hammer - stil no luck.
Any suggestions.
See photo's the water pump is in block -different from your example.
Thanks very Dave

A lot of people seem to have this problem. There is another method where you can use some long bolts threaded into the holes of the pump and then drive them against the case to push the water pump out. But, I have also heard of a lot of people breaking the tabs off of the old water pump too, while attempting this. It sounds funny, but I would try a bigger hammer. Sometimes a rubber mallet just isn't going to cut it, and these tend to get really, really stuck sometimes. People always manage to get them out, but sometimes you have to ratchet up the force that you use.

Put a piece a two foot long 2X4 on the pulley and give it a good rap with a 5lb hammer to shock it off. The combination of coolant, old gasket material, clamping presurre and heat have formed a kind of cement that has epoxied the pump to the cylinder head. De facto expoxies can create a very strong bond but have virtually notensile strenght.
