Radiators - Koyo vs The REST

And one more time - because I have to always ask - The all AL champion is a direct fit. Tranmission cooler and all. Nothing special I have to do but drain the coolant fluid pop a few hoses off, install this one, reinstall the hoses, fill it back up with coolant...Not looking for a crazy project. Just need a good radiator replacment.

Yes, it is a direct fit.
 
After reading all of the posts, I ordered a Champion CC1998 radiator for $254 total. Toyota dealer wanted $211 for a plastic/aluminum OEM. Going for the upgrade because I don't want to pull it again. Lifetime warranty against leaking. Planning on towing my boat again soon here in Florida it gets hot. Getting a ASE certified mobile mechanic to install it at my house for $100.
 
Champion CC1998 install

2000 Toyota 4Runner SR5 3.4, 225k mi Champion CC1998 install - Here is a photo after installation. From reading other posts and watching YouTube videos, I wrote down the steps on radiator removal from watching the videos..When I took the skid plate off, it was a mess. Cleaned it up and painted it black. .I don't believe it was the original radiator, it didn't have any Toyota mark on it..plastic and aluminum, split on the seam at the top, in pretty nasty shape..I did most of the work myself, and paid a mobile mechanic $70 to help me with some of the install...we had to bend the hangers straight a little bit on the new radiator to fit, and widen the mounting holes a little in the truck with a drill... I knew this would be the case from watching the videos and posts on the Champion 1998 install.. Also had to bend the hangers straight out of the way on the skid plate as well because the new radiator is a little thicker and not quite enough clearance to hang it. All in all, I'm happy with with the install. I hope this info helps someone, like the info helped me.

My Koyo just started leaking, or at least I just noticed that it is leaking. After checking my Amazon order history I realized I have had it for 4.5 years so not a horrible product but could be better. The leaks are at the junction of the aluminum core and the plastic tanks. It appears to be more towards the ends. I decided to try and tighten up the junction by carefully compressing every aluminium tab with a Vise-Grip, the whole time being careful that the adjuster on the Vise-Grip didn't move in order to maintain consistent compression.

So far I have drove the vehicle about 20-25 miles and the radiator is bone-dry on the exterior, (knock on wood) unlike yesterday's test I performed to determine the leak location. Yesterday I rinsed off the radiator with water before driving the same route as today and noticed coolant on the exterior after the same 20-25 mile route. If anyone else has issues with their replacement radiator leaking it might be worth it to try to compress all of the tabs before buying another replacement.


I was having really frustrating issues with a radiator of similar design. After every trip to town I would park, then after a min or two the top and bottom of my radiator where those teeth are would spurt out a little fluid. I thought it was defective from the factory and was close to buying a new all aluminum radiator. I scoured this forum and found your post about clamping those teeth down. I clamped all the ones I could reach top and bottom. Now after 3 trips and probably around 80 miles I have had no such issue. Shitty quality control from the radiator factory.

I just wanted to come back on here and say thank you for the suggestion. This saved me a couple hundred dollars and possibly even the sad prospect of leaving my 4runner at home this hunting season.

THANKS A BILLION!!!!!!!! :banana:
 
02 SR5 w/automatic: Just finished installing new radiator purchased on Amazon (Denso 221-0508).
Cost me $94.79 + tax, no shipping fee.
Arrived undamaged within 2-3 days.
Installed at same time as B&R Trans cooler, smooth and trouble-free.
Quality seems good, no issues noted.....hopefully stays that way.
 
[MENTION=14566]2000se[/MENTION] where did you purchase that one? It says it is made in Japan and is an OEM part.
How much $ did it set you back? Inquiring minds want to know.

I just picked up a 2002 and it has the original radiator. Guy owned it since 2006. No pink milkshake ever and I want to nip that in the bud

Before I explain - (Preface) I know I'm going to catch ____over it for paying like I did. I bought the part and then took it to my dealer to have installed. I love my truck and don't mind paying to have correct maintenance done on it. I buy the same part and replace. I've a good relationship with my service dept. so they back their work on it.

I picked it up from here:
Radiator Assembly - Toyota (16400-75181) | Toyota Parts

Paid ~$350 for installation which included install, new fluid, new thermostat, and new hoses. So all in all total around $700

You're the man. I didn't think there were any of these still in inventory stateside. Overpaying? That price is a steal IMO. Let them laugh.
 
I drive my truck e v e r y s i n g l e day. I mean every day. I have to have a reliable vehicle. And this truck has seemed to prove that to me that it is. If I take care of it.

Now I need to find some wood to knock on :D
 
I didn't think anymore existed that were made in Japan. $350 is probably what the dealerships would charge for a radiator.

Did you get yourself a new radiator cap as well? As you might as well change that with your radiator in case the original cap is starting to degrade.

Is it common for a radiator to make it 341k miles? I have a 99 with 160k miles on it and I'm thinking about replacing now.

I would go ahead and change it. I bought my 4runner with 341k on the clock and the original radiator. I changed it because the top plastic tank had really fine cracks forming. I waited until the last minute, and I'm lucky my radiator didnt blow, because I had a pinhole leak that formed in less than 30 miles one day when I finalky decided to change it.

Get a quality radiator, and change it asap. I was dumb and waited until it was almost too late.
 
I don't want to revive an old thread but this is one of the newer ones that I referenced when looking for a rad replacement and did not see any of this information so I wanted it here for others in the future. This is from my personal build thread that I will also link for context. Niteghost's Build Thread

Regarding the radiators for our vehicles, there are two PNs.

16400-75181

&

16410-AZ011

There is a lot of discussion on which is the better radiator, which is made where..etc. I called a few Toyota dealerships to try and get to the bottom of it. This story lined up at every dealer I called but ymmv. I was told that the "AZ" Part numbers are manufactured by Southeast Toyota. Although they are replacement parts they are not 'True OEM" parts is what I was told each time. I have heard some people say that the 16400-75181 "Expensive" one is the made in Japan vs the AZ is China/Taiwan and while I cannot speak to that it would make sense. The parts managers I spoke with said the AZ/Southeast parts are meant to be cheaper alternatives for consumers to use for replacement.

I hope this clears up any confusion some may have had. I know while I have been looking at getting a new one I have seen lots say Denso, TYC, KOYO, OEM Toyota. I try to stick with OEM parts when I can but was super confused with the two different Rads at two very different price points. Based on what I have heard I would imagine the TYC, Koyo, Denso and the AZ/Southeast Toyota part are all probably made in the same spot just rebranded for each of them.
 
I put an aluminum (Champion) and I'm happy with it. Sure it costs more up front, but it will NEVER corrode, develop tiny cracks like plastic ones, or fail in the typical plastic/aluminum issues. Plus...it's all shiny and that's a plus
