for a week or 2 i have been searching and reading alot of posts about air in the cooling system. I have since bled her profusely but to no avail. i have a spare water pump and thermostat that i will be attempting to install today. Is there any trick to installing them? or is it just straight grunt work. from what i can see i need to take off my fan, remove the belt and just unbolt the old one. is there anything im missing? if my old pump is bad will i be able to easily tell? thanks for all the advice guys.

super easy and straight forward. simple tools and just crank the tunes and go at it. nothing tricky at all.

yeah its super easy, just dont slack. get a good RTV seal on it and everything.

if youve got small hands and wrenches you may be able to take it off with the fan still on. sort of a biotch but saves time

i just want to make sure that this is going to fix it all guys.

the deal is this, after i drive the upper rad hose is HOT. the lower is ice cold. the rad cap is cold. my thoughts are that the pump is not moving the water so the water in the upper is boiling and going back into my reserve tank. am i just completely off?

I believe that is your thermostat not opening. Perhaps you should start by replacing that. Then if that does not fix your problem replace the pump.

why waste time
do them both same time, you already would have everything off and out of the way
knock them both out doesnt matter if one is bad, at least both are new now
id replace the hoses too if necessary, one time to bleed it all and fret over it. cooling is very important

Just make sure the thermostat in new, and OE. Used units are just as risky as the one you have now, and most aftermarkets are different sized openings, or have a different design on the spring and don't work as well.

EXACTLY!

A tip: If you're having trouble breaking the existing RTV seal off the water pump, take a wooden dowl or something similar and place one end against the pump and hit the other end with a BFH from the top (make SURE you have all the bolts removed first, of course http://forums.freshalloy.com/images/graemlins/tongue.gif).

LOL, not me. A friend of mine pounded the crap out of his on his Z and accidently left one bolt in. Funny thing is, he didn't realize it and kept beating on it until the head busted off, at which point he discovered... "oops".

ya know with every passing mod i do to this car, everytime i work on her, i am amazed at how easy they are to DIY. i just replaced my water pump in a matter of minutes. i am simply astonished. how do u know if ur water pump was bad? cause i dont really see any signs of it being bad.

Generally there's leakage at the weep hole, or you can hear the bearings groan.

just one small problem. the water pump i installed does not have the bolts installed to hold on the pully and fan... just go to home depot?

OEM doesn't come with the studs and Nissan is out of them. I just pulled them out of my old water pumps. Half of them stripped as I pulled them out for some reason.

When your all done I suggest you keep your water pump. Replacing it all in one shot is great, but you wouldn't want to toss a perfectly good water pump.

yeah i kept it. im a pack rat anyway. im gonna clean her up and stare at it constantly.

Ditto, my KA OE pump came with the studs as well.

For some odd reasons Nissan doesn't give new studs with S13 SR water pumps but they do for S14/S15 SR water pumps. At any rate, you might have purchased the pump from us quite some time ago because since couple months ago we complete the water pump kit with new Nissan studs free of charge.
