Hmmm well don't have any close up pics real easy to find though. The pump could actually look like it's just a pulley it's pretty small and does have a pulley wheel bolted to it directly. If you look at your alternator then from the alt follow the belt to the left you'll see a little wheel where a belt runs across the top of it well that is your water pump!! The wheel unbolts and you move that onto the new pump so don't damage it getting it off or your buggered!! The water pump is semi easy to get off obviously you need to drain your coolant first probably a good idea to stick in some new stuff anyway, then all you need to do is loosen the alternator adjustment screws and the main bolt at the bottom so you can push it all the way in so you can mount the belt back on later on, then unbolt the pump which has a nut and 4 bolts i think off the top of my head one might be hidden by the cambelt cover not sure been a white since i've had it on mine, you don't need to take off completely i think you can get away with undoing most the bolts that hold the cover on and then you can move it enought out the way to finish undoing the pump and to take it off!! Just word of advice try and find a water pump with a cast impeller these are better than the ones with the bent bits of steel. But if you cant find any don't worry too much won't make that much difference just my personal preference on the pumps we can have. Also while you got it apart might be an idea to replace the thermostat if it's not been done in a while they quite often get stuck and cause the engine to overheat and they are only a few dollars just might need to get a new seal for it upto you or worry about it another day if it goes wrong. Whats the problem you got fluid coming out where the pump is on teh pulley wheel??

It takes a breaker bar with a pipe extension usually. I've never been able to get one off with a 1/2" drive impact gun even. But if you're changing the water pump, why do you need to take off the bottom pulley? All you have to do is loosen the water pump pulley bolts, then take the alternator belt off and unbolt the water pump. It's pretty simple and only takes like 20 minutes to do the whole job....

Do not use a GMB waterpump or it will start leaking after a year... NPW is a good brand and also don't forget to pull the plug on the timing cover and take out the hiddel 10mm bolt holding the waterpump in place.

you have to somtimes pull the enitre timing cover to access that one bolt. wich is fine couse you should be doing the belt too. ive never had a problem pulling a crank pulley with anything but a 2 foot breaker bar. somtimes even a 1/2" drive ratchet. people never beleive me but i swear to it. rusted, sitting in a field, hasnt run in a decade, never been a problem. knock on wood;)

Those thermostat housing bolts are the worst. I would go find another housing at a junkyard. If you can pull your own part, make sure you can remove those bolts before you buy it. Using lots of penetrating oil helps to loosen the threads too.

What I meant was if the junkyard will let you pull the parts you need (instead of them doing it for you), make sure you get a housing where you know you can get those bolts off without breaking them.
