Hi guys. Has any of you Mazda mx250 owners had to change the water pump?
I think mine is leaking and need to know if I should attempt it my self.
Cheers

Water pump is a standard service part TBH.

I changed the water pump on my Mx5 not too long ago, and tbh it's actual a pretty big job. There's a lot of "stuff" in the way. It goes all the way down to the thermostat cover having to be taken off. There was a few good guides that I followed,

So you have to take off aux belts first (for me this proved to be a nightmare as the bolt that the alternator "rotates" on to adjust tension had seized and I actually ended up tearing the top half of the bolt off the bottom half, leaving just the thread in there and still in the way!)

Then you have to remove your cam belt assembly, Guide: http://www.mx5nutz.com/forum/index.php?showtopic=52586

Then finally the pullys, cover thermostat and water pump, Guide:

As I said it was a fairly big job for me and took all day (8 hours!) but I'm not a mechanic by any sorts. Only ever "tinkered" and and changed oil/plugs/a few gaskets here and there.

Hope that helps
