| looks from the photos you've got all 5 bolts out? (certainly the most awkward one nearest the block)
Probably still stuck in there from the gasket sealant, might need "persuading" |  |

| As Matt says, it might need a "bit of persuading, but don't persuade too hard, the housings are alloy.....

| Another alternative is to spray carb cleaner around the joint or if you have a drop of petrol apply that with a paint brush. Both of these have chemical properties that dissolve adhesive; it has worked for me in the past. Of course the unknown factor is what has been used as a sealant; hopefully nothing too over-the-top.
Good luck.

| In my experience it's usually corrosion, not sealant, that makes pumps difficult to remove. My trusty medium weight plastic-faced Thor dead blow hammer has always won so far though. Don't be tempted to try and split the pats with a screwdriver or you'll potentially ruin the machined faces.
The pump in the photo looks like fairly new aftermarket one, what's the reason for removal?

| Thanks for all of the suggestions. The reason for removal is constant overheating. I know it could be a number of things but this was next on the list after recoring the radiator, installing a new thermostat and changing out upper hoses. Upon getting a good look at the pump it does look fairly new. Since I’m already in it and have a new pump and lower hoses ready to go I will proceed. I am thinking though my overheating could be something else.
I’ll keep you guys updated. Thanks and cheers. | |

| Things like ignition timing, fuel mixture (look for vacuum leaks), valve clearance and potential HG leaks would be my first ports of call. Overheating is usually not related to the cooling system in my experience (although you probably have the early type radiator, which is allegedly less effective than the later ones, something I have no experience with), unless it's the rad and expansion bottle caps not sealing properly. As said, I have no experience with the early V4 cooling system so I'm not exactly sure of the set-up, but a common issue with the later type is that the rad and bottle caps have been swapped, which can also lead to overheating.

Can I ask when you recored the radiator, did you add an extra core? Always a good idea.
I'm with Melle, there are lots of reasons for overheating, other than the water pump.
I'd check compression to see if you get a clue about the state of the head gaskets + all the other things that Melle mentioned.

| Have some old butter knives which I use to slip between the housing and gasket to encourage separation.
The blade is also used to clean up the gasket faces afterwards. | |
