How long before Water Pump Replacement 2015

Just purchased a 2015 V6 with 85,000 miles. What is the service life of those water pumps?

 

i honestly think my water pump is the source of my squeaky belts and always has been. i think it drags.. but you cant tell by listening to anything. Been dealing with it since around 65k. around 106k now

 

Have 404,000 on my pump

 

My wife's 2003 Corolla had 256K on same water pump. If I were to replace a 1st gen or 2gen water pump for preventive maintenance I would say 135K. If I had a turd gen then probably 3 thousand miles would be my goal.

 

114K on my 2010 and haven't touched it.

 

The water pump will usually give you quite a bit of notice if there is an issue. It’s not a preventative maintenance item in my opinion.

I would be more concerned about your idler pulleys, lower control arm bushings/ball joints, and steering rack. Oh, and your door lock actuators...

 

You know man
I don't know. These parts seem to have different life expectancies. For example, many 2nd gen owners, despite high miles and years age, have never looked at their rear brakes.
But on a German car, rear brakes would already have worn out by now. But they're discs/pads.

Same thing for water pumps. On German cars? 100k mile item. Their bearings can fail. The impeller can fail. The seal holding coolant in can fail.
Coolant is slippery. Something has to be causing your belt squeal. And yes, if coolant gets on there, that's not good for the belt.
If I were you, I'd figure out if the system has a leak.
You can inspect visually. Maybe clean off the area. I don't know of other ways such as if there are UV dye additives.
But a common way is pressure testing the system. I don't know the best safe PSI/pressure to test it at, or what the radiator cap opens at. Stock or TRD cap.
As to avoid bursting anything.
Maybe 10, 15, or 20 psi?
That pressure test can help expose coolant from leak areas. Or a vacuum test that sucks it in and makes noise.
Or you can just say fuck it, load up the parts cannon, and start throwing shit at the truck. Which in this case, would be just one part. The water pump. Which is not so bad. At least then you have piece of mind knowing it's replaced.

It's not like a parts cannon with suspension, where a person might be unable to pinpoint a specific noise and then spend a lot replacing each and every many suspension component.
A water pump is just one part. Not ten.
Well I guess two if you add a thermostat or something else.
On the plus side, if the vehicle is due for new coolant, this lets you do that.
Also supposedly lack of coolant replacement (if that happened) can also lead to corrosion and debris that may not be good for water pumps

In general though, Toyota parts seem to last longer than many cars, for whatever reason.
I don't know if they're better designed. For example some of the parts look weird.
So maybe the WP could have a longer lifespan.
Plus WP getting changed on passenger cars is usually because it's done at the same time as routine timing belt service. Whereas 1GR-FE V6 has timing chain that lasts longer.

There's not too many places to check for leaks. Water pump. Hoses. etc.

 

I don’t know if there is a “Service” recommendation?
I will probably replace mine when it starts leaking or I feel it isn’t cooling sufficiently.

I would service the Coolant (Anti-freeze) by 100k or 10 years
Then every 50k or 5 years.

 

Squeaky belt not me? But I have had serpentine belts get glazed that squeaked and replaced to solve.

Water pump, I have replaced on a Chevy truck... when it leaked. I was just asking to find out how long they lasted.

 

Is this for 4.0Ls, 2.7Ls, or both? I’ve got a 2.7L with almost 122K...

 

It's a water pump....it will give you signs that it's gong bad! But very detailed none the less!

 

So you just use the same interval as any other vehicle. When the water pump fails or leaks excessively you replaced it.

 

I have 146k on my stock one... Waiting for signs...

 

Ok guys thanks... just checking to see if I needed to R&R before long, and its winter here in Iowa.

 

What I remember.....1st Gen 3.4L---when U replaced the T/belt

Just replaced water pump same time....that was 90-100K IIRC

Yes...we're talkin' 4.0L

My '14 has 91K & original w/pump

 

I've worked on Toyota since 2005 and have only replaced about 10 water pumps on 4.0s. They are not common and coolant replacements usually prevent failure.

More common is idler bearings howling. Alternators as well.

 

Yes I had to replace alternator at 132k on a 2006 prerunner, it was the source of high pitched whine. Word to the wise don’t try to save a few dollars using a cheap replacement, use the OEM Denso. I’ve owned six gen 2 trucks never had to replace a water pump all over 100,000 miles. I do replace coolant every 3-4 years regardless of mileage.

 

I just replaced my water pump. I have a 2015 with 75k miles. I am the second owner.

When I bought the Tacoma last November 2019, it had just under 72k miles and the dealer said they swapped all fluids. No way for me to completely verify that, but when I swapped the water pump, my coolant was still nice and pink.

Anyhoo, I had a chirping ticking noise. I had just driven about 200 miles back home, parked the truck, came back 4 hours later and the noise started. First time I ever heard it.

I had recently (like 500 miles previous) replaced belt, pulley 1 and 2's, and the idler pulley. Thought it was a stretched belt so swapped that with an OEM belt and the noise was still there. Also thought it was my power steering pump after a recent steering rack upgrade (tundra rack!). Eventually I found the noise with a mechanic's stethoscope...and by slowly turning the fan clutch with no belt on.

I have never changed a water pump on any vehicle, and with the awesome youtube video and numerous write ups on here, it was surprisingly easy and straight forward.

 

I learned about cheap alternators, after 2 Pos AutoZone ones I went to the auto electric shop near me and got one professionally rebuilt.
