1994 Altima Water Pump Removal (bottom bolt hard to reach)

I'm trying to remove the water pump on a 1994 Nissan Altima. I have removed all of the bolts on the water pump except one. I can't reach it with a wrench or socket. The bolt is below the water pump pulley. Can anyone tell me if I need a special tool or if there is a secrect for reaching the bolt easier?

How do you change a water pump on a 2001 nissan altima?


Just did this over the weekend with my 2001 Nissan Altima. First, remove the negative battery cable to prevent shorting. Drain the radiator by removing the drain screw. To gain access to the water pump, I had to remove the upper radiator hose to the engine, unattach the reserve tank hose from the radiator and take out the reserve tank, remove the alternator and the lower alternator bracket because it blocks access to one of the water pump bolts and move the serpentine belt out of the way. This should give you free access to the six bolts that attach the water pump. You will probably have to hit the water pump with a rubber mallet or some other tool to break the sealant on the water pump, but it should then just come off. The hardest part of the job for me was removing the bolts for the alternator bracket because they were on extremely tight. Reinstall your new water pump after applying sealant to all parts that will attach to the bracket, and your ready to put it all back together. If you have the right tools, this should take probably 4 or 5 hours to complete.

How do you fix the water pump on a 1997 nissan maxima? Where is the water pump located on a 1997 nissan maxima?


The water pump is located behind the timing chain cover. There are two black plates on the front cover. The one near the front of the car has the water pump behind it. The other one has the timing chain tensioner behind it. First you must drain the coolant. Then support engine and remove engine mount. Then remove drive belts. Then remove the two black plates. Push the tensioner in and lock it with a paper clip. Then remove the two bolts holding the tensioner and remove tensioner. Then remove the water pump bolts. Rotate engine crankshaft the take tension off of water pump (about 20 degrees). Then install two bolts into water pump threaded flange (M8). Tighten M8 evenly as water pump will come without damaging it. Check for corrosion. Then replace with new one. Make sure you use new "O" rings. Lubricate with engine oil. Put the original three bolts back in the water pump. Then install timing chain tensioner and black covers. Replace belts and engine mounts. Add coolant and pressure test system.
