Hi,

Water Pump - A device, usually located on the front of the engine and driven by oneof the accessory drive belts, that circulates the coolant by causing itto move from the lower radiator-outlet section into the engine bycentrifugal action of a finned impeller on the pump shaft.

INSPECTION

The majority of water pump failures are attributed to leaks of somesort. When the pump seal fails, coolant will begin to seep out of theweep hole in the casting.

How can you tell if the water pump on a 1997 - 275e625.jpg

Signs of leakage from the water pump vent means the pump's seal is bad. Courtesy of Federal-Mogul Corporation.This is an early indicator of trouble. The seals may simply wear outdue to abrasives in the cooling system, or some types of seals crackdue to thermal shock such as adding cold water to an overheated engine.This could also cause other internal parts to fail.
Other failures can be attributed to bearing and shaft problems andan occasional cracked casting. Water pump bearing or seal failure canbe caused by surprisingly small out-of-balance conditions that aredifficult to spot. Look for the following:

  • A bent fan. A single bent blade will cause problems.
  • A piece of fan missing.
  • A cracked fan blade. Even a small crack will prevent proper flexing.
  • Fan mounting surfaces that are not clean or flush.
  • A worn fan clutch.

TEST

To check a water pump, start the engine and listen for a bad bearing, using a mechanic's stethoscope or rubber tubing.
  • Place the stethoscope or hose on the bearing or pump shaft.
  • If a louder than normal noise is heard, the bearing is defective.
WARNINGWhenever working near a running engine, keep yourhands and clothing away from the moving fan, pulleys, and belts. Do notallow the stethoscope or rubber tubing to be caught by the moving parts.There is another test that can be performed on vehicles with an engine-driven fan.
  • With the engine off and the fan belt and shroud removed, grasp the fan and attempt to move it in and out and up and down.
  • More than 1/16 inch (1.58 mm) of movement indicates worn bearings that require water pump replacement.
  • To determine whether the water pump is allowing for good circulation, warm up the engine and run it at idle speed.
  • Squeeze the upper hose connection with one hand and accelerate the engine with the other hand.
  • If a surge on the hose is felt, the pump is working.
  • Any air being sucked into the cooling system is certain to have a detrimental effect.
  • It cuts down pumping efficiency and causes both rusting and wear at a rate approximately three times above normal.
  • To test for aeration, have the engine fully warmed up, all hose connections tight, and the coolant level up to normal.
  • Attach one end of a small hose to the radiator overflow pipe and put the other end into a jar of water.
  • Run the engine at a fast idle. If a steady stream of bubblesappears in the jar of water, air is getting into the cooling system.
  • Check first for a cylinder gasket leak by running a compression test.
  • If two adjacent cylinders test low, the gasket is bad. Otherwise, there is an air leak somewhere else in the cooling system.
REPLACE

  • When replacing a water pump, it is necessary to drain the cooling system.
  • Any components--belts, fan, fan shroud, shaft spacers, or viscousdrive clutch--should be removed to make the pump accessible. Some pumpsare attached to the cylinder block as shown below.

  • Loosen and remove the bolts in a crisscross pattern from the center outward.
  • Insert a rag into the block opening and scrape off any remains of the old gasket.
WARNINGWhen working on the coolant system (for example,replacing the water pump or thermostat), a certain amount of coolantwill spill on the floor. The antifreeze in the coolant causes it to bevery slippery. Always immediately wipe up any coolant that spills toreduce or eliminate the chance of injury.
  • When replacing a water pump, always follow the procedures recommended by the manufacturer.
  • Most often a coating of good waterproof sealer should be applied toa new gasket before it is placed into position on the water pump.
  • Coat the other side of the gasket with sealer, and position the pump against the engine block until it is properly seated.
  • Install the mounting bolts and tighten them evenly in a staggeredsequence to the torque specifications with a torque wrench. Carelesstightening could cause the pump housing to crack. Check the pump tomake sure it rotates freely.
  • The water pumps on many late-model OHC engines are driven by theengine's timing belt. When replacing the water pump on these engines,always replace the timing belt.
  • Make sure all pulleys and gears are aligned according to specifications when installing the belt.
To be really honest, it depends on person to person. For some people it's easy and for some it's tough. The procedure is above for your model. You can judge yourself.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

I have a 2000 nissan maxima gle 3.0 do i have to take out the engine to cjange the timong tensioner it has a rattling sound


Larry, normally engines do not have to be taken out to change timing tensioners, the bumper assy., A/C condenser,radiator,etc is removed to get access. Best if you get yourself a manual.
Check the attached links,instruction and guides, Good luck

I am about to have my water pump changed on my 1996 Nissan Maxima. If there is water in my oil what other problem could it be beside the water pump? Thanks, Sandie


I just had to changed my water pump today. Its not the difficult for person handy with tools and a common sense demeanor for cars. Unfortunately, if its not the water pump, then its most likely the Head Gasket.

Does your oil look milky or foamy? If so go to next...

Do you see water with antifreeze dripping under your cars motor near the passenger front tire? "If so, then its most likely your Water Pump Problem"

If not, then its your head gasket!

My 1997 Nissan Maxima 4 door sedan is leaking coolant/anti-freeze. What could be the source of this leak? We fill it up and after several days it is out and the engine gauge is running hot.


could be the water pump. where is the coolant coming from?? behind the a/c compresor?? if so, you need a new water pump. need to know location of the leak or at least general location if you can not get exact.

WATER PUMP REPLACEMENT QUOTE


I don't have a labor manual in front of me right now but i can tell you that it's not cheap. The water pump is driven by the timing chain which requires a bit of labor to get to. If i recall correctly it's at least a 3 hour job so depending on your local labor rate it should be around $350-550.

I need a water pump in my 1995 maxima and it has a timing chain. The dealer tells me its less expensive to change out when the car has a timing chain rather than a timing belt. An independat mechanic tells...


your engine has a timing belt not a chain and the water pump is run by the timing belt,and when the pump is changed the belt should be too,it should run you about $300 if the job is done right with the pump,belt,idlers and tensioner if needed,hope this helps

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.

1997 nissan maxima with 3000 24 valve twin cam v6. I am need a water pump.What comes off to change.


Hello and thank you for using FixYa!

To replace the water pump, you will need to remove all the drive belts. Then there are 2 black covers on the front timing cover. One cover is for the chain tensioner, the other is for access to the water pump. I would recommend you replace the tensioner the same time you do the water pump. The reason is, you need to remove that tensioner so the chain has slack. When the chain has slack, you can then unbolt and pull the water pump out. It could get stuck, so there are bolts that you need that you would use to run in to pop the pump free.

Hope this helps , Thanks Jay!
