Well, its smart to replace it when you do the timing belt, cause if it goes bad then your basically gonna be back where you started when you were replacing the timing belt. If your having it done, labor will almost be as much as the timing belt. This way, you dont pay double for labor.

From what I hear replacing the water pump is a pain. You have to take off the timing belt (which is a lot of work and you need special tools for it.) But this would provide peace of mind.

On the other hand if you don't replace the water pump and it goes out when your driving you will have to pull over right away and get towed because it would over heat otherwise.

Hope this help.

Anyone else?

Do you know how many miles the water pump has on it?

I have no idea. I bought the car used with 63,000 miles on it. So it is safe to assume 63,000 miles

Well unless you feel comfortable doing the timing belt yourself, you are going to have to pay out some money to get it done. I personally would just wait until the water pump goes bad or 120k miles and then do the timing belt and water pump all at that time. A water pump should last a lot longer than 60,000 miles. I replaced my last one with over 100k on it and it was still working just fine at the time.

Thanks I didnt know if there was another reason other then location of the pump/timing belt and money.

It should be alright. If you start seeing coolant on the ground under the oil pan, its time to replace it cause its coming out of the weep hole of the water pump. Thats a sign that its time.

You can get the pump for 35. So that is one of the cheapest things in the whole motor. So change it and be safe. It is a waste of time to go through all of that. I replace belts, water pump, auto tensioner, pulleys on my timing belt changes. So if it is off replace it.

if you dont know change it since your there its a cheap fix rather than going through all the hassle.

Do you have a link to the site that sells it for $35? I only saw them for $130 and up.

Well I am not "there" because the timing belt has already been changed. Are you refering to mileage? And if so that is what I am asking if it is neccessary for me to change it after the timing belt has already been changed.

My Brother and I Both have 160,xxx miles on are 2g daily drivers and have never replaced the water pump when we did our belts and built are heads. I know it is a good idea to but I believe that 2g water pumps came with mettle propellers and not plastic ones like some cars so they are a lot more durable. So if you only have 63,000 miles on your motor I think you will be just fine till its time to change the timing belt again.

I am sorry it was 29.

I found out the hard way.I had my belts changed and 1 year later my pump started to leak.Once you are in there you should change everything just to be safe.

Thank you for the link.

Is this OEM and is this all I would need to change the water pump?

If this is all I need then I will buy it and pay for it to be installed.

I will say it again for all the slow people. The timing belt has already been installed by the previous owner.

A water pump is "scheduled" to be replaced every 120K miles. Most people just go ahead and do the WP and TB at the same time for piece of mind (I do), but it's not required. However, with the car being as old as it is time plays into things as well.

The key issue is not "do I need to change the WP?" but did he at the very least change the auto-tensioner and balance belt along with the TB" If not I would highly recommend changing those and while you're in there do the pump plus seals and the other pulleys and tensioner.

If the auto tensioner and BB have been changed and now that you have the car "after the fact" I would say just keep an eye on things and don't let the car overheat if the WP does fail because you will have to remove the TB in order to change the WP. Kind of a PITA if it's not currently required even if you are competent to do the job.

My good buddy's 1995 TSi AWD has 139k on the original 7-bolt, still has the OEM pump on it. At the end of last year the pump was just beginning to howl and the car was heating up a bit during extended idling, so it needs replaced.

My '92 TSi FWD made it to 128k on the original water pump and it started to growl and make some horrible metal on metal bearing sounds, although it still cooled just fine.

Around 120k seems to be the croaking point of the OEM pump. If the OP's at just 63k, his pump is probably at about half it's lifespan. Unless the car sat for a long period of time, I wouldn't hesitate to continue to run the existing pump.

Coming from a wiseman, that scares me. Just because someone has alot of miles doesnt mean many others have failed earlier. For 29 I would replace it. This thread is starting a major divide. If install is a problem, there are many people that would help you out. I am a cheap laborer, but I am in Washougal(our garage). So your choice. I think listening to people say push it to it limits(not their words), then soon I will be saying I told you so. Your choice now.

I'm simply using my personal experiences with pump lifespan to back up the manufacturer's recommended service interval of 120k.

At 60k, Mistu recommends belt replacement only....at 120k they recommend belt, tensioner pulley, idler pulley, auto tensioner, and water pump replacement. Sure there will be some water pumps that fail at 90k, but there will also be some that last to 180k. I've also had my share of new water pumps on other vehicles that lasted just 30k before they began to seep, so it's a gamble any way you look at it.

I imagine the advice would be a bit different if the OP had the front of the engine torn apart. However, since it's "buttoned-up" with only 63K on the car and no discernible issue, there is no point in opening it up again for a part that should be "good-to-go" for many more miles.

I will agree that just because the service interval is at 120K, that doesn't mean that it will last that long. But I also don't believe that it should be of concern at this point. "IF" he keeps an eye on thing he will be able to tell when the pump is going bad.

The real issue to me would be to know whether the balance belt and auto tensioner was change along with the timing belt. That will do more damage and be harder to judge when going bad and/or fails.

You got it on that one. It is a gamble. That is why I never trust what someone else said they did. The only way you are sure it is done right is to do it yourself or have a quality shop do it. Then you know truly what was done. Even if you keep an eye on it, it could still go when you are in a place that would make it tough to get it repair. I would hate to be 100's of miles from home and notice that my temps keep climbing. That is just my 2 cents. I think this thread has enough info for the guy to make a wise decision.

Thanks for everyones input in this discussion.

I have know idea if they changed them. I guess it would be safe to assume that they didnt. If I had to change them would I have to take the whole car apart? My thoughts are that if I have to take the car apart to change them then I would change the pump as well only if the kit below has everything I need to replace it.
