Best replacement radiator for the money today...

[supercoupe91]

Where did you see it priced like that?

Looks like serra has been 365 to 384 in the time ive been trackng, maybe 2 years. I just looked during all the 20 percent off sales, all in it bounced between 300 and 283. You still have to pay some shipping. I stopped tracking sep 2025.

Its a gamble though, and likely not worth what you save using a local dealer. Serra Decatur did pretty good packaging it and getting it to midwest.

I paid 283 for an oe 100 series rad and 440 for a liland alumnium for 3-fe that looked like a drunken elf welded it.

Original rad lasted 24 years before cracking at top.

The original 98-02 part number was <16400-50210> and the original '03-'07 radiator was <16400-50290>
Some years ago, the 98-02 part number was superseded by <16400-50360>. More recently, it seems the 50360 radiator is listed as the replacement for all years 98-07. All these radiators are interchangeable and probably fine for all of North America.

The <16400-50290> radiator, is the best of the bunch but also more expensive and maybe unnecessary. I suspect it'll go by the wayside in the future. If you have a lot of trinkets blocking the radiator, the 50290 might be the best choice for all years.

Do we know what makes the 16400-50290 radiator the best of the bunch?

Higher fin pitch (Fins per inch).

Would that translate to cooler operation in a warm climate...say Texas?

My Toyota parts department people I've used for 25 years. Say we've 3 radiator P/Ns (OEM T-rads) in North America: CN, USA, and Mexico spec. We can only order USA & Mexican spec, in USA. The difference they say, is environmental manufacturing standard they're built to. USA is highest standard, in removing pollutants for manufacture process. We see this in thermostats. 06-07 is different P/N and cost more. But both PNs (98-05 & 06-07) look and act the same.

You'll also find in mud published pictures showing different fin picture.

Bottom line. I've found no benefit, in buying the pricier rad. Someone living in a desert may, IDK.

The idea is to stay within normal operating range, not necessarily, the cooler the better. But if you are regularly hitting say 220 degrees, I'd consider going over your existing cooling system (Fan clutch, clean radiator fins, etc) before anything. If you desire better A/C performance at low speeds, I'd look into adding the OE condenser fan that was removed in 2003+

Understood. Thanks!

I replaced my original radiator back in 2019 at 320k miles with a new OEM due to browning tank plastic. It did not leak. That was 6 years and 80k miles ago. The replacement is now leaking along the upper tank to core seal and needs replaced. This is disappointing and about the life expectancy I have for an aftermarket radiator, not a Toyota.

I have one of these going in as soon as these rest of my parts get here from Impex.

Well that sucks. My replacement OEM radiator has 130,000 miles and is still going strong, but the original only lasted 60,000 miles. I guess it was more due to age than miles.. I have read that aftermarket radiators are a crapshoot. Some last as little as 3-6 months.

Bummed to read/hear this - getting ready to dive into this project in a couple weeks to replace my browning but not-leaking, original radiator (2004 with 171k miles). My goal/hope was to not think about this for another 20 yrs following the work...

What is the tariff situation these days on Impex orders?

NOT GOOD! I have a whole comparison I'm going to post soon.

EDIT: @CruiserDreaming: Impex order update here.

I read the comments about the part numbers and replacements, but does anyone know if the mounting points for 16400-50290 and 16400-50360 are identical? or are there variations due to the application year? Does the 16400-50360 line up and work with 05+ rigs?
