About T. Rad
T.RAD North America was established in 1988 as "CoPAR, Inc.", as a joint venture, or Co-PARtnership, between Toyo Radiator Co., LTD of Japan and another North American manufacturer. The primary goal of this joint venture was to support the growing agricultural and construction equipment markets in the United States. Hopkinsville, KY was selected as the home of our facility due to its centralized location.

Our initial product line consisted of various sizes and configurations of copper/brass radiators. In 1991 Toyo gained complete ownership of CoPAR. The CoPAR name was kept until 2005, when every member of the worldwide Toyo group was renamed "T.RAD" to present a truly "global" presence.

Over the years, the company has experienced continuous growth; necessitating several plant expansions and acquisitions of new equipment. Our copper/brass facility, which started at 61,000 square feet has now expanded to nearly 100,000 square feet. Most recently, this facility was upgraded with the addition of a vacuum brazing furnace, allowing us to produce stainless steel heat exchangers. In March of 2000, we celebrated the grand opening of our aluminum products manufacturing facility; a 100,000 square-foot operation, located approximately 3 miles from the copper/brass facility in Hopkinsville, KY. It was established to produce aluminum radiators and oil coolers for automobiles, motorcycles, ATV''s, and off-highway equipment. In the years since, our aluminum facility has experienced an exponential amount of growth. T.RAD North America is now the leading supplier of aluminum radiators and oil coolers to the motorcycle and ATV markets. In 2005, this facility was expanded to nearly double its original capacity to facilitate this growth.

T.RAD North America continues to grow today, Come Grow With Us!

Denso still no ETA. Funny how Toyota and Lexus can get them all day long for double the price but nothing on non OEM side.
From what @hoser has clued us into, Denso not our OEM manufacture of series 100 radiators T.RAD is.
 
I did not realizes when I asked if you've used that the last sentence was from you @ponyti. Are you the author of points A.-F.?

The above makes reference to lower pressure. I'm wondering if any issue from low pressure like getting adequate flow to rear heater or back pressure on water pump?
yes those were my points, in a former life I was involved in heat transfer/airflow and cooling system design in performance applications... lower pressure I was referring to was the pressure that builds up in front of the radiator (damming effect) with a 4 core radiator in theory you get higher flow rate (coolant spends less time in the radiator) 2 core less flow so in "theory" a longer soak time which takes more heat out... it's all a trade off 4= more surface area 2= more effective soak time...
in my opinion this is a small V8 that is NOT working very hard, low compression, few restrictions air in /exhaust out large surface area radiator... large open grill... it just doesn't have a large cooling requirement
 
I've used 2 of them with no problems.. direct bolt up...
So this means thickness of this radiator is the same as OEM, fan shroud distance from engine and foam air/dust dams gaps the same.

Did you replace foam, use old or go without?

Go with Koyo. I have them both in my 80 and 100. Exact fit and virtual duplicates of the originals. Mine have plastic tanks. In AZ they work great. Ned

How about you; Did you replace foam, use old or go without?

the 2 row are physically the same size same tank thickness, just not crammed with fins & tubes the full thickness ...
always use the foam... new or old... you want the radiator sealed to the radiator support... you want all the air that enters the grill flowing through the radiator not around it...
 
Ordered a Koyo radiator about 5 years ago to replace a leaking OEM on my 99. Seller shipped me a CSF. I had them get me a Koyo, about twice the price I remember. Both units were identical. Installed Koyo.

Wife's 03 now has leaky rad, I ordered CSF at $136. Install in a few days, will post any issues. Also tried to order denso with no luck.
 
They show in stock. I called them today. BO, Not in stock, no ETA.
Even KOYO's I called on are BO.

I went with @ponytl recommendation just before they rasied the price $10 2282 Fits Toyota Landcruiser 98-02 4.7 Radiator V8. It arrived early, I opened top of box and saw the same number molded into plastic as all my factory's have (>PA66-GF30<), so must be the OEM plastic top at least.

Edited: This radiator did fit properly, addition I had to open up holes (grind out, covered by poor manufacturing) to bolt on.

PA66= nylon
GF30= 30% Glass filled -

Plastic mold could be China knock off with the required composite stampings-

For others looking in with later model year 100s, I believe there is a different application on 03-07; I was told the mounting tabs are in slightly different locations, & outlets may be in a slightly different position.
 
Jumping in late........where did we end up? Not leaking but Im replacing my rad in an 05. Could be plugged to a degree. Can't find a denso either.
 
I became frustrated with each online supplier I called, stating in stock (Denso & KOYO), but phone called revealed NOT.

Was installing last night, but stop as my new radiator didn't have foam seal on top. Need adhesive to attach old foam to new rad, then will see. Looks like it will fit, but need to inspect further.
 
:(

I called this company to confirm fitment prior to ordering. My concern was Dealer has different part number for 98-02 then other years. They assured me "theirs" was correct fitment for my 98-02 application.

Installing I was not happy.
  1. I was not prepared (poor planning) to glue old foam (top & sides) onto new radiator, so was held up a few days.
  2. Brackets along bottom that retain fan shrouding are in wrong position on new radiator. Took some modifying.:(
  3. Should have checked each bolt hold prior to installation. As luck would have it, the last bolt (PS side lower shroud bolt) I was installing (wasting an hour trying) I could not get to thread in. Finally I decided to remove radiator again to see why this bolt would not thread into side bracket of new radiator. Turns out they wielded nut in off center. I had to modify hole with cutting bit then re-tap.:bang:
  4. Lower radiator hose neck stuck out further then OEM (twice the length). I'd needed too pushed fan shrouding back further to install and removing rad. As I removed new radiator to modify, that extra long lower hose receptor neck made getting pasted shroud difficult, doable but difficult. What I didn't notice was; the extra moving back of shroud flipped the wire harness brackets into radiator fan fins. I sure hope I did cause leak.:mad:
  5. New radiator is thinner, resulting in a small 1/4" gap between upper foam and radiator housing.

This Radiator worked on first warm up, but I'd not order again.:ban:
 
Looks like they may have sent me wrong radiator.

Anyone have picture of 2003 - 2007 radiator back bottom side?
 
Thanks.

That 03 looks just like my 00 LX470 factory. The aftermarket they sent me has everything on bottom in slightly different position, fan shroud hooks that needed modifying, as will top foam air dam. The picture they have on ebay appears to be just like our factory. The Toyota & Lexus Dealer show different part numbers for 89-02 then for 03-07. What the difference is I don't know, since your 03 appears the same. I've read something about change in fins IIRC, but don't know.

I replaced Steering rack bushing last night and took on test drive, all seemed good with radiator. But I'm just a little concerned foam air dam along top isn't tight enough.

Darn, last thing I wanted was an aftermarket wasting my time.

The seller is going to ship me a replacement, hopefully the first one was some kind of error.

Is it the picture or is the replacement appear 2-3" wider?
 
It's the picture, and old support are on new radiator. Width fit fine except thinner so OEM foam along top left 1/8 - 1/4 inch gap. The radiator lower hose tube is over a bit and longer as are transmission line.

Seller says he doesn't know what happen, will see what he sends now. He's agreed to send without me shipping back first, as in my 100 now and I'm not pulling again tell I'm see what he sends.
