Shop Nissan Water Pumps

If you decide to do it; be SURE NOT to get coolant on the timing belt. completely drain the cooling system first and I would advise placing a very absorbant rag under the pump and kind of stuffed between the engine and time belt cover to catch any antifreeze that may drip/drop down onto the belt. Reason: the antifreeze will cause damage to the time belt and cause it to break prematurely. when this belt breaks it causes major internal engine damage. The last broken time belt I repaired on one of these engines cost the owner $3000.00 parts and labor. too expensive to take chances with. good luck with the project! rick

The "book" times are based on knowing what you are doing and have average tools on a vehicle with no obsticles like rusted bolts that can slow a job down seriously.

A 1991 could be an open book as to how long it would take. You may consider doing lots more than just the pump while you are there too. Do you want to flush system, new hoses and thermostat while it's drained for the pump?

What engine is in this - I haven't checked on possible procedures as of yet,

Not hard at all take it in and a couple hundred dollars later it’s all done. LOL
Sorry but you have to confirm that it is the pump first and then get yourself a repair manual that covers this job. After you’ve read the procedure then make the choice of whether you want to attempt this.

It sounds as though you may have caught the O ring when you were reinstalling it. Did you use any type of lube on the O ring?

I don't know if you have a pressure tester but the best thing to do would be to take the cover off & pressurize the system to see exactly where the leak is be for tearing it down...

I'm assuming you weren't getting this mix before the water pump replacement.......

You could be correct, but while I was waiting for a answer a nissan mechanic told me when you change out that pump it will injest lots of coolant in the oil pan during the process, he might be right because before I started the engine up I checked the oil and it was way over fillled, I thought I was just reading the dip stick wrong and ignored it. I will change the oil tommorow and let you know if that solves the problem, Thanks for the responce.

Bammm, Yes I remembor this engine now, So sorry. There is actually three chains, and a two part chain thensioner.
the tensioner is to the left if looking at it from the front. the tensioner and the guide. there is still a trick,though pretty laimen, with the valve covers off, vice grips can hold the cams. anytime timing is an issue, it should be done right though and You take You're chances doing it shadetree style.

I solved the motor mount problem,but now have another question. I have the cover off of the timing chain tensioner and I can wiggle the plastic part of the tensioner sideways, and this is with the timing chain on normally how it should be. Does anyone know if this is normal ?

If I have a mental picture of what You are talking about, It's been a long time since I have done one.
Are You talking about a flat piece that has what appears to be very small flare out's at the ends and sits on would be the outside of the belt ? if it is what I am thinking, Movemant is normal. Are You also since tension is being taken off the belt, replaceing the timing belt too with the water pump. Rule of thumb, replace the belt with pump. There is a tool to kepp the timing in place while replaceing belt, can be done without but pay seroius attention to location of sprockets and a couple pair of vice grips will help along with a long 3/8 punch and a white or yellow paint pen.
It is a little difficult, but someone seriuos about doing it with a little attention can do it. You sound as if You are willing to do it right and if that is the case, You will be fine.

Thanks for the answer, this engine has a chain and is extremely hard to work on.

Which year?

2000

There are three belts. Alternator, PS, and AC. Which ones are rubbing together? Was there any recent repair work done prior? Visual inspection of the pulley alignment as HT stated should give you an answer.

Its the AC and Alternator belt. If you look at this picture its the area where the belts cross together between the two idler pulleys

Maybe the water pump is coming apart.

That is the most likely thing to make a grinding noise and belt alignment problems.

Thanks for your help guys. I will check the water pump today. If this is the problem, is it a thing I can fix on my own? Ballpark estimate?

Thanks

I don't know. Can you tell me if I would be capable of tiling my house? We don't know what your abilities are.

Ive changed out a radiator, brakes and average things on cars. What I was asking is if I will need access to things that a typical person wouldnt have, like a lift or a special tool. I have pictures attached of the pulley. The pulley in question had an extremely small amount of play that's hard to notice.

Thanks

That is the belt tensioner pulley and will have play when the hold down nut is loosened but shouldn't have any when tight. It appears you're missing half of the outside belt and that needs to be resolved.

Thanks Hammer Time. I ordered a new belt. I still haven't figured out why those belts are rubbing as everything seems to be tight and in working order.

I assure you that either there is still a problem or they were installed wrong in the first place and my money is on that there is still a problem and you are just going to ruin the new belt and when whatever is failing lets go all the way, you are going to be on the side of the road.

Something caused that belt to run off the side and you need to find it. Look for any pulley that tends to lean when the belt pressure is on it.

I'm going to examine this further over the holiday weekend before putting on the new belt. Thanks again for your help.

Sometimes temporarily putting the belt on will help you spot the misalignment.

Can you tell me if I would be capable of tiling my house?
NO!!!! You don't have the patience for it.................lol..................

Haha Brian......................... That's why I hired someone to do it.

LOL...I was expecting you to comeback & say "that was a trick question"..........I already did it!!!!!

I did the same, paid someone to do it......

I've watched guys do and it really doesn't look to hard but then thought of the saying I always say..........A good professional always makes his job look easy

Btw....The white flakes that you see in the pictures was the bar soap I used on the belts

That's happening because there is a failure in one of the components causing the belt to run off the side of the angled pulley. The noise is likely coming from the bad component,not the belts rubbing together.
