Awesome thanks so muchHave to confess I've never used a slide hammer so cannot comment - I'm sure there are a few guys on here who can advise - @Lee , @t-tony @mrscalex to name a few (other brands are available).
My method meant I was not putting a force inwards against the plate but pulling the pump outwards with the plate attached by the seal.
I do not have A/C so on the M44 there was plenty of room. I would suggest you put the puller on and give it a gentle squeeze - with luck it will move.
EDIT - just found this in my files - this guy used to strips of angle iron to spread load.View attachment 124397
I'm kinda regreting that I did not start or warm up the car first before doing the water pump. I'm in the last stages of my cooling system overhaul. I didn't want the new heater hose running from the cylinder head be put on an old radiator because it's a pain to remove hoses once they're set. So I decided to just remove the old radiator and thermostat but the water pump happened.... But oh wellSome gentle heating around the pump might help.

By the way did you ever use WD-40 to help pull it out? I hear others have used it to help pull the water pump out.Have to confess I've never used a slide hammer so cannot comment - I'm sure there are a few guys on here who can advise - @Lee , @t-tony @mrscalex to name a few (other brands are available).

Certainly did refer to initial comments - left it soaking overnight - once it started to move slowly continued spraying.By the way did you ever use WD-40 to help pull it out? I hear others have used it to help pull the water pump out.
lol sorry i'm reading multiple threads. gotcha.Certainly did refer to initial comments - left it soaking overnight - once it started to move slowly continued spraying.
Same here. But like others, even if you're careful, the pump can be pretty seized with a hardened o-ring for the previous owner didn't replace it on time. The longer you wait, the higher probability the o-ring gets stuck.I did my M44 cooling system overhaul in the Summer. It won't help now but, when I wound the two bolts in to push the pump out, I was careful to ensure they were both seated and tightened equally and at a quarter of one turn at a time. After each equal tweak, I tapped the pump body lightly with a hammer. It is very easy to effectively jamb the pump body in the aperture by forcing it out, out of square. My car is a 97 and it was the original pump.
I do not know what my car's previous owner used but having seen some of the tricks `he' pulled if it had been changed I doubt whether it was BMW spec . However, there were no deposits and O ring did not feel hardened - mileage was 64k............ The previous owner didn't use BMW BLUE but an amber coolant perhaps Zerex G-05 or Peak Global Lifetime. This then convinced me further to use BMW BLUE and following an interval change.
GS-48 is the equivalent of BMW Blue. GS-48 here is not easily available. It's supposed to be under a xerex valvoline brand but I see mostly GS-05.I do not know what my car's previous owner used but having seen some of the tricks `he' pulled if it had been changed I doubt whether it was BMW spec .

I have used Comma X GS 48 since (which complies with BMW specification) at three year change interval - you can get it at reasonable on-line prices.
I've probably missed it in another post but where are you based?...................GS-48 is the equivalent of BMW Blue. GS-48 here is not easily available. It's supposed to be under a xerex valvoline brand but I see mostly GS-05.
