IBT Posted April 19, 2009 Share Posted April 19, 2009 Help Help Help. To all you pathfinder people. The water pump I pulled of my 1988 SE is not the same as the ones that the auto parts stores are trying to sell me. I do not know if someone has put a different nissan motor from another year in this 1988 but as you can see in the pictures below the old waterpump does not look anything like the replacements. Either for a 4cylinder or the 6cylinder which is what I believe I have? Any Idea's or help would be a lifesaver at this point..Wife needs the pathy for work on Monday!

OldSlowReliable Posted April 19, 2009 Share Posted April 19, 2009 are those just pictures of what you were looking @ online? if so, it could be that they use a generic picture for every model, but idk, sorry? Link to comment Share on other sites More sharing options...
adamzan Posted April 19, 2009 Share Posted April 19, 2009 Is your truck a 2wd? Because yours looks like a 2wd water pump....Mine is like the one the autoparts store sold you. Link to comment Share on other sites More sharing options...
IBT Posted April 19, 2009 Author Share Posted April 19, 2009 (edited) Is your truck a 2wd? Because yours looks like a 2wd water pump....Mine is like the one the autoparts store sold you. My pathy is a four wheel drive and the bottom picture of the new water pump is what they sold me for my model car and engine but was obviously wrong. I did not look at any of the 2 wheel drive waterpumps. I did'nt even know there was a difference! Edited April 19, 2009 by IBT Link to comment Share on other sites More sharing options...
Slick Posted April 19, 2009 Share Posted April 19, 2009 both my rigs (91 & 92) have the h2o pump pictured below yours...... i would go with the 4cyl 2wd thing Link to comment Share on other sites More sharing options...
unccpathfinder Posted April 19, 2009 Share Posted April 19, 2009 that looks like a 2wd water pump...I have one thats brand new if you're interested it could be possible that someone also swapped in a maxima or altima engine so you can use the 2wd HB water pump the maxima/altima pump has a shorter snout Link to comment Share on other sites More sharing options...
IBT Posted April 20, 2009 Author Share Posted April 20, 2009 both my rigs (91 & 92) have the h2o pump pictured below yours...... i would go with the 4cyl 2wd thing I am doing some checking now on the 2wd pump... thanks guys for all the comments!

unccpathfinder Posted April 20, 2009 Share Posted April 20, 2009 heh well good luck...its probably a good thing tho b/c i have no idea where that WP is right now...I know i did an 86 maxima swap and had to buy a 2wd water pump...i bought the maxima pump but it wouldnt work with the truck pulley system...so you may want to try an 86 truck 2wd water pump Link to comment Share on other sites More sharing options...

It was the rugged rock forum I saw the King for sale on. Glad your spoiling it not selling it. BTW still can't find the right water pump. I did look at some 2 wheel drive waterpumps but no luck. I did look at a 1988 D21 nissan pickup h2o pump and it was almost exact except the snout was too short. help!!! Link to comment Share on other sites More sharing options...

As it is I had to take Monday off to head down to the nissan dealership and try to figure out what engine this waterpump came off of, so I can hurry up and put it in with the new timing belt and thermostat.

nunya Posted April 20, 2009 Share Posted April 20, 2009 The one you have looks almost exact to the one from my old HB. Try having them match it to a 91 2.4l (ka series,not the z series motor)4x4. Hope it helps. Link to comment Share on other sites More sharing options...

IBT Posted April 22, 2009 Author Share Posted April 22, 2009 Arrrhhhh, still no luck finding the right water pump! Talked to the local nissan dealership and they cannot pin point what motor or model of car this h2o pump came off of. This is crazy. How many possible engines can you put in a 1988 pathfinder body? The long arm water pump is supposed to be the one but it is not the one I pulled off. To be honest the closest pump I can find to the one I pulled off is from a 91 300zx crazy huh. But the snout is still about a quarter inch too short and I cannot mod every other pulley. I did check the other suggestions you all gave and still no go. Any other Ideas would be great, PS how hard is it to rebuild a water pump? Link to comment Share on other sites More sharing options...
k9sar Posted April 22, 2009 Share Posted April 22, 2009 The 'wings' on the wide water pump do nothing but provide a mount surface for the timing cover. The only part that actually seals is what you have on your water pump. The one for the 2wd is like yours, the long one is for 4wd. Link to comment Share on other sites More sharing options...

And K9sar I thought about buying the 4wd pump and moding it to fit...Cutting off the wings...but the height of the pump is way wrong too. It's too short compared to the old one I pulled off. Infact its just a Quarter Inch taller then the nissan 300zx water pump. Link to comment Share on other sites More sharing options...
unccpathfinder Posted April 23, 2009 Share Posted April 23, 2009 out of curiosity does this truck have an efan mod? b/c with my VG I couldnt use the car pump b/c the pulley/fan would foul on the timing belt cover...I look fwd to the pix later on Link to comment Share on other sites More sharing options...
IBT Posted April 23, 2009 Author Share Posted April 23, 2009 out of curiosity does this truck have an efan mod? b/c with my VG I couldnt use the car pump b/c the pulley/fan would foul on the timing belt cover...I look fwd to the pix later on Uncc I'm not sure what an efan mod is. But here are some pics of the engine. Notice I don't have a place for the extra long water pump that all the parts places say I need for my 1988 pathy. this last picture is showing the exact place of the old water pump. Any Ideas as to the Model or year of this engine would be awesome also knowing exactly where to get the water pump from. Link to comment Share on other sites More sharing options...
unccpathfinder Posted April 23, 2009 Share Posted April 23, 2009 hmmm...going to go check the block i have on the shelf...it looks like to me someone was lazy with the last timing belt/wp change and put the wrong one on there...be back in a few Link to comment Share on other sites More sharing options...
unccpathfinder Posted April 23, 2009 Share Posted April 23, 2009 yea...ok that looks like the maxima engine I used...can you snap a pic of the timing belt covers b/c they're very different from what I have with the "winged" water pump I just thought of this...the TB looks like it has a round tooth belt on so if thats true its a newer engine...someone please chime in about the round teeth belts and what years had the square teeth and when they went to round I'm not much help right now... I just did some checking the 2wd D21 WP has hte same part number from 86-95...i'm still going to place my bet on that...even the winged water pump should mount to the same holes b/c the block castings are the same...try to get a nissan pickup (D21) V6 water pump and it should work b/c I can't think of anything else it would be...the maxima pump had the same mounts as the d21 but the snout length was significantly longer on the D21 and was what i needed for my accessories to work Link to comment Share on other sites More sharing options...
k9sar Posted April 23, 2009 Share Posted April 23, 2009 (edited) The VG30I from 1988 had a square tooth application... looks like yours has either a round tooth belt or a worn square tooth. Your cams look round tooth but I can't tell on your crank. Anywah, the key is your timing cover. Take a look at the pics in this thread to see how the wide pump fits (and I can tell that your block should have one from the flat surfaces to the left of your water pump. The wnd of the water pump actually seals the timing belt area. If you have the covers for the wide pump and someone threw on a little pump, you would have an opening above the tensioner where crap and water would get into the timign cover and... from the looks of your cam sprockets... it has. thread with pics of front of VG30E (same block as VG30I) oooohhh I just had a terrible thought... perhaps the previous owner snapped off a water pump bolt and chose to put the smaller one on rather than extract the bolt so the right one could be installed. hmmmm.....

Much thanks people I will be doing some more checking tonight. Although it does not look like anyone made any modifacations to the fan to accomadate a longer waterpump. But I will be looking for all kinds of stuff broken bolts included and will let you all know what I find with pictures...thanks again.. Link to comment Share on other sites More sharing options...
