water pump problem in 2013 leaf

[CHLPatent]

Its out completely or working poorly? Unlike a regular car, you can drive a limited amount on your LEAF. The inverter will heat up and likely trigger the fans when temps get high (I know, you are thinking "fan?? What fan?") Be prepared. When they kick on, they are quite loud. In 13+ years of LEAFing, mine only kicked on one time. I was cruising thru Snoqualmie and stopped for a pee deposit. Parked, shut off the car, peed and about 3 mins later just as I was about 3 feet from the car, the fans kicked on and scared the beejeusus out of me!
Sounded like the car was about to take off.

A few weeks later, I was out in the garage and noticed the car was making more noise than normal when charging despite charging for barely an hour. It was the pump. So grabbed some LEAF Spy and compared it to earlier data and it did seem it was running a bit warm.

So took it in and the pump had a broken impeller and tech guessed it was doing no more than 20% of its normal flow. So it was replaced and all was back to normal.

During this time, I not only climbed over (and back) Snoqualmie, but drove around averaging 50-100 miles a day for a few weeks before realizing something was amiss.

My saving grace?

Free DC charging for most of that time. Does not use the inverter so it only heated when driving.

Just a nitpicky tech thing from an EE - it's AC to DC converter and DC to AC inverter.

Is there an inverter in the Leaf? It would be nice to be able to use the DC voltage from the Leaf battery to power my house through an inverter changing the DC to AC.

My 2023 Ford F-150 Lightning DOES have an inverter and several 120vac outlets and one 240vac outlet - called ProPower on-board.
Using a neutral switching transfer switch I can power some of my house circuits up to 30A max total.

So I think I have a water pump issue on my 2013 SL. The amber warning light is on and It is reporting error code P31E8(00). As far as I can tell the part number is 21581-3NF0A. However, this part does not appear to be available. All of the Nissan part web sites list it as out of stock or discontinued. I called the dealer and they quoted me $900 for the repair but also said they could not get the part at this time and did not know when they might be able to again. I might try my luck on the nock off ones on eBay.

Has anyone had to recently change the water pump on a 2013-2017? Where did you source the part?

Thanks in advance.

Did you have any luck? I have the same problem but with a 2012.

Hi, Did you ever make any progress in getting the part? I have almost the exact same problem with my 2012. John

Lots of those on Ebay, under $200 from China; $300+ domestic. I paid $350 three years ago to replace my #1 pump. I just noticed that my #2 (lower) pump is making a rattling/buzzing noise when running. I didn't realize it before, but it looks like both pumps are identical. I kept the #1 pump that I replaced, so I think I'll open it up and see if it's repairable.

Edit: The #1 and #2 pumps probably have different Nissan part numbers because they come with the mounting bracket which you don't have to replace. The old pump just pops out of the rubber gasket of the existing bracket and a new pump slides into place.

nitpick if you must but its a single unit and creating 2 from it will only cause confusion. What you probably meant was the device has two functions.

People nowadays mix the terms up calling everything an "inverter" or a "converter."
As a person with an engineering degree it stands out to me, but no big deal I suppose as long at the AC and DC input/output is specified.

For power circuits:
If the input voltage is AC and the output DC, it is a "converter."
If the input is DC and the output is AC, it is an "inverter."

But the term "converter" is a more general term and is used for other things like Analog to Digital Converter.

Dictionary definitions:

An AC-DC Converter is a device that converts an AC voltage to DC voltage.

An electronic device that reverses the sign of the current or voltage of a signal or power source. Also called phase inverter. An electrical device used to convert direct current into alternating current.
