Replaced with an Aisin and no complaints
I got this kit and it’s working good, all that matters is the water pump is aisin
WP, like everybody else said. It sounds identical to my water pump on the same engine when it went. If you DIY it’ll be about $200 (Aisin pump plus new coolant), shop will charge $1000+. It’s an aggravating DIY job. Whether you DIY or have a shop do it, use a OEM replacement made by Aisin. Labor costs are too much to have to re-do it in a few years. I’ve seen prices down to $100 on sale.
I used the same ASIN water pump on my 4GR FSE 65k miles ago. Been great. No leaks or any issues. They are the OEM manufacturer and do not want to create a separate mold for the same product. Every bit as reliable.
I bought Aisin brand instead of Nissan OEM parts, hopefully they're as good or better.
That\u2019s what I have in mine and I\u2019ve had zero issue with the water pump.
The fel pro gasket set and head bolts + head bolt tool will be close to 300 and then you'll need RTV sealant. Another probably 200 for the Aisin water pump.
Here’s my experience with the 2019 for what it’s worth:
Bought a 2019 with 5.0, xlt with 20k miles for $41k in Aug 2022.
-Water pump and vct’s replaced at 50k miles.
-New engine at 98k miles due to oil consumption (2 dealerships and 4 months later). Replaced in Aug of 2024
-102k miles the trans started acting funny, fully grenading at 112k miles. Replaced Feb of 2025
-126k miles and the transmission cooler fails midway through a 3hour trip with the pop up camper and family in tow.
The water pump was defective as well upon diagnostic. Leak in coolant as well. 2022 with 20k miles.
The part they had sent to replace for a recall leaked all of the coolant out. Luckily the tech caught it and ordered another part.
