16400-75181 Radiator: Made in Japan

fourfive · Jan 26, 2022

There's already a few threads on this & wanted to add to the confirmation that the more expensive Toyota radiator with pn 16400-75181 (~$365) are made in Japan & comes with a radiator cap. From what my local Toyota online parts guy told me, the cheaper Toyota/Denso 16410-YZZAJ, 16410-AZ011 or Denso 221-0508 (~$150) were offered to compete with lower cost aftermarket radiators & were usually made in Taiwan. Comparing the 2, the one that's made in Japan does seem to have a better build quality & wasn't beat up during shipping compared to my older Denso radiator that's made in Taiwan. Also, the first Denso one I got years ago had a leak when I first installed it which I was able to exchange for a new one.

Does the made in Japan radiator have a proper drain port?

hmm, based on what I see here it's only applicable to 2000-2002 models...I wonder if one would work on my '98.

I am fairly certain the radiators fit all 3 gen 4 chassis. Not just the 2001 and 2002. Hopefully another forum user can confirm this.

It does. Same drain port that were on both my 3rd gens that had the original factory radiator from Japan.

Wow that's fascinating, I've never heard of this. I've replaced a few 4Runner radiators and even when I went through the dealer, I got the cheaper Taiwan Denso which looked essentially the same as the original but the writing on the top was different, didn't include a cap, and obviously made in Taiwan. I also had one of those leak right out of the box but figured it was a shipping mishap.

That's wild. Thanks for the info

Last I checked, radiators for automatic 3rz & 5vz 3rd gens were the compatible.

I didn't think the Japan made ones existed anymore. And that inventory dried up on them.

this is a pretty cool find and thank you for sharing! I've been following the conversations around where the radiators are produced over the last couple years and I though the "JAPAN" made was completely non-existent!

That’s cool. Don’t be scared of the other one though. It’s a quality piece. That said, if this one was a known option, I would have bought it.

Even the Chinese koyo rad from NAPA I put in my ram 2 years ago was a nice piece. Chinese doesn’t always equal garbage, just most of the time…..lol.

China is capable of making great parts. They’ll build to whatever spec you want for a price. Problem is everyone likes their cheap bs…..easier to make money and most people just don’t care at the end of the day.

By the way, there’s a much higher percentage of Chinese parts in newer cars now. Start opening up Dorman and Cardone boxes….. you’ll be surprised at what you find.
