One question, my radiator has no writing on it whatsoever. Carfax says my water pump was replaced at 66K (before I owned it) but no mention of the replacing of the radiator. Does anyone else have a factory Toyota radiator without any markings on it whatsoever on that square flat part? Thanks By the way the radiator looks perfect (right now)

Is there any adhesive left behind as though a sticker was there at some point? or maybe even a "dirt shadow"?
 
I've seen at least one post where someone had a radiator that had failed again. Not sure if it was in this thread or a different one. I don't know which revision they had though. 16400-50384 is the latest part. My 2013 truck would have had 16400-50383 from the factory and the dealer replaced it with 16400-50384, so we'll see if it lasts any longer, but given there have been 4 other revisions (16400-50380 through -50383) my suspicion is no, Toyota just changes the part # when they introduce a new model year

I understand what you're saying, BUT, when I went in to buy the PN appropriate for a 2008, they recommended to buy the 16400-50384 as it has been updated, so it seems like Toyota is recommending the older MY URJ200s use the newer PN rad.

Unless ofcourse, if what you say is in fact true, then we're screwed either way. But I'm still waiting for someone to report the 16400-50384 has failed in the same exact manner, proving the same failure mode has NOT been mitigated.

Nothing there - No adhesive or any markings whatsoever. It's super clean. Will post a picture later on or tomorrow of it.

Time will tell. Toyota has only been using that 4th revision part since August 2016.

My original was stamped but the new radiator is a sticker. I suspect there was a sticker that came off. Either that or it was an aftermarket Denso that just didn't have a sticker.
 
Update to my post on the previous page (#413)

Toyota USA Customer Service has offered to cover half the cost of the radiator replacement. They will be sending me a check in the next few weeks.

The cost was just over $1200, so this was a nice relief. I searched all over mud and was able to garner some tips that helped my case. Below are the tips that I believe helped me the most:

-Most importantly: Honey not Vinegar. Despite your frustrations with the radiator, don't take it out on the rep. Lots of pleases and thank yous will go a long way in having your rep go to bat for you. Initially the rep mentioned that there were a few amounts ($200 or $300) that Toyota might be able to offer. Being pleasant and patient got me $600.

-I mentioned I have owned multiple Land Cruisers and this part failure is inconsistent with Toyota quality, specifically on their most expensive model.

-I explained how a hairline crack had formed where Toyota stamps the part number and that if it had been stamped on the curved surface, I don't think it would have failed in the same way (or at all).

$600 is pretty reasonable relief, particularly for being out of warranty. My Toyota extended warranty covered $758 of my repair (radiator & coolant were $460 and the labor was about $250 so I guess about 2 hours). I had to foot about $160 for the hoses and clips which were considered "wear items". (Yes I know the clips should really be reusable, but for $36 I wasn't about to argue). All of those prices on my invoice on the prior page are probably list prices. I'm assuming the additional you paid included the fan clutch and maybe some other parts as well. I opted to skip the water pump, fan clutch, and thermostat since I still have 2.5 years/23k miles left on my extended warranty and Toyota won't cover it until the water pump starts weeping.
 
The diesel radiator and expansion tank have arrived. The expansion tank design, has several benefits...

It draws steam and air from the top tank. Steam is quite abusive to the glass filled nylon tank, much more so than hot coolant in liquid form.... part of my hypothesis is that we have a steam problem, it is deteriorating the plastic and of course eventually causes it to fail at the weakest point. By removing the steam and keeping the tank full of liquid, the breaking down of the tank is slowed substantially.... so much so that 1VD equipped Cruisers do not have this issue.
Removing the steam and air for deaeration prior to running the coolant through the heat exchanger portion of the system will increase efficiency. This increased efficiency may allow the system to run at a lower pressure, again increasing tank life. We have an additional liter+ of coolant that is active in the system, rather than sitting outside of it in the overflow tank, doing nothing.

The radiator appears to almost be a bolt in. The unknowns right now, are the fan and fan shroud. A tee in the lower return hose, to bring coolant back into the main loop, just prior to water pump and t-stat, will be a custom part.

Please call Mishimoto and ask them to start building radiators for 200s. We spend thousands of dollars upgrading and “bulletproofing” our trucks. Why keep replacing it with with the exact same part that you know is going to fail, again. The more people that call, the more incentive they will have to start building them.
 
Do a little research on welded aluminum radiators. They are not a good long term replacement IMO. I hope to prove that the factory solved the issue for us with expansion tank.

So have you tried installing the diesel rad into your 200 yet?
 
so much so that 1VD equipped Cruisers do not have this issue.

Are we sure that is the only reason VDJs don’t see this problem? My understanding has been that direct injected diesels (as opposed to IDI) transfer less BTUs into the coolant for a given HP production in the first place.

That said, I like where you are going with this. When I lifted the hood of my new-to-me 200 I was shocked to see it didn’t use a “surge tank” setup like nearly every new car produced for years now. Not sure whether this is an overarching toyota design philosophy or something just for the cruisers, but it is one place I wonder whether toyota could have done better.
 
No, wrapping up some projects on the BJ73 before the 200 can be pulled off duty for a bunch of reworking.

Are we sure? No. However, there is little doubt that the expansion tank is an upgrade to a cooling system. The 1VD, being a diesel, with twin turbos, and an EGR cooler, should have more issues with steam and air.... that's the hypothesis, anyway.
 
Most of my diesel experience is with VWs, and it isn't exactly scientific but in a hot place like where I live the fans will run on a similar generation gas jetta/golf far more than a diesel one. A TDI jetta will often simply not warm up if left to idle in very cold temps. Gas engine? Different story. The radiators seem to go a lot longer on diesel jettas as well. And yes, those engines do have turbos and high-flow EGR that is cooled.

Again, not to say this won't be an improvement over all. I just wouldn't be surprised to see similar failures eventually if that radiator has the same raised part number area and is used on a gas engine.
 
Final update:

I got my check from Toyota on Saturday for $613 :)

Very quick turn around as I sent in documentation on 6/27 and they had told me 6-8 weeks for the check.

Mine was installed October 2017 in my 2015 LX570 it’s OEM from the Lexus dealer because the original had a bent fin from a minor collision;) the new one looks perfect after 9 months

I'm replacing my radiator in the morning with a mid grade Rock Auto unit. $155. 09 LC 145k miles. It blew while I was on vacation in Little Rock and I put some radiator repair putty on it and it slowed the leak enough for me to go from Little Rock to Dallas and home to south Mississippi. I probably put about 20 ounces of water in it along the way. And yes I'm going to refill with Toyota coolant after the replacement.
My question is, no one has mentioned topping off the Transmission fluid after the radiator replacement. Not even on the Toyota shop receipts. Is it such a small amount it doesn't matter?

After I did mine I asked the local dealership about it. They said there wasn't enough lost to worry about it.

At 145k, it may be worth it to go ahead and get the trans fluid flushed by the dealership anyway. At least you will know the correct amount is there.
 
So what's the ongoing consensus with reimbursements from Toyota? I didn't go thru the 20 some pages. Did you just call and state your case or was there more to it? Is it luck based?
