Water pump woes

Hi Guys. I'm having a problem with a new water pump and wondered if anyone had experienced the same. The seal and bearing on the old one are pretty shot so I've got new one, however unusually the issue I'm having is with the new component. There's a little outlet on the top which is for connecting to the cab heater matrix. The new unit has a little metal lug in it with a square head. I have tried absolutely everything I can think of to get this flippin' thing out and failed.

I'm sure it's meant to come out, the parts manual seems to imply it does. There were no options for different pumps when I bought it. I've used a micrometer to compare the aperture between old and new and they match. My last option is to take it to an engineering firm get it drilled and tapped.

Has anyone experienced this and got any advice? Have I somehow ended up with a dud unit? I'm hoping to go away in my little commer in two weeks time so any advice would be massively appreciated.

P.S. - I know I keep promising, but I will get some pics up soon:I
 
A slight up date, my very wise wife suggested I should put osme images up so you could see the issue. So here is the new pump with the little silver lug and (now slightly rounded!) square head in the top right.

Here is the old one with the little screw in to attach the heater host to shown on the floor to the right.

Try gripping the the flats of the plug in a vice and twist the whole water pump to see if you can loosen it.

Could be loctited in, in which case a bit of heat will shift it :)

I just bought a similar pump from Speedy Spare - with the same plug in place. Easiest way to remove it is to put the flats of the plug in a vice - tighten very tight and then use soft headed hammmer on the body of the waterpump to shift it, and then rotate to remove. Worked fine for me. Just make sure you are revolving in a clockwise direction from above.

Took me a couple of minutes, but my vice is large and sturdy.

Replying for my other half - as he's currently down the pub for a 'village meeting' :p.

Thanks for the advice - vice approach sounds very promising - we'll let you know if it works.
 
Well, I'm back from the 'village meeting' now and I've secured access to a vice. I don't yet have a workshop so everything is done in the carpark, however a friend has offered me access to a vice. I'll give it a go and let you know what happens, otherwise it's the engineer's workshop.

My better half has already posted some pics here:

We'll get some more of the interior soon for you to have a look at. Credit to the missus, her interior design has turned out stunning and Titch is slowly coming together!

Really gutted we can't make the meet this year, next year I hope to be able to. It would be great to put some faces to all the names on here.
 
Good luck with the vice = the bigger the better - and make sure it is well secured to the workbench. Remember to use a soft headed hammer and to go gently.
 
Well I got up bright and early this morning to give the vice trick a go.... believe it or not I managed to break the vice trying this method![V]
So before I totally loose all vestige of anger control and toss the stupid thing into the sea, I've decided to take the easy route and I've handed it to a local engineering firm to sort out. I thought getting the old pump out would be the difficult part of the job! I'll let you know what happens next.
 
Hi All. thanks for all the great advice. As I mentioned I took it to an engineering firm in the end who sorted it all out. Apparently the manufacturer had put a lot of locktight in there. Can't really think of a good reason why but there you go. Anyway all sorted now and installed and functioning cheerfully!
