Bruce, Did you get the pump housing bolt hidden behind one of the heater hose nipples? There are 6 bolt altogether holding that housing to the block, 3 on each side. You may have to remove the nipple to get the bolt out if an open-end wrench doesn't break it loose.

After removing the bolts holding the pump housing to the block, the whole thing is stuck. Is it supposed to come off with some puller? I have banged and prised(as the Brits say) and heated the housing with a small torch(but maybe not heated it enough?), but it is stuck. I've been hesitant to apply too much force or heat... Any suggestions? BTW, I learned by doing it that the only way I could get to the crank pully was to remove the fan from the end of the water pump. Thanks for any advice.
