Best replacement radiator for the money today...

Found a great thread on Denso & Spectra radiators. From my brief reading of the thread, my guess is the Denso radiator has better cooling/thermal transfer performance for both engine coolant and transmission fluid. However, the Spectra appears to have a more reliable transmission cooler construction. (This is assuming those companies use that same design for their 100 series radiators).

If somebody has an old T-Rad radiator sitting around, I'd be interested in seeing one cut apart. I know a couple have received replacement T-Rad radiators that leaked upon install. It easier to fix leaks at the end tanks than anything internal. I'm surprised any radiator would leave a factory without being pressure tested. I wonder if said radiators were damaged during shipping.

Radiator comparison: Denso/Spectra/OSC - Honda Ridgeline Owners Club Forums

I try not to check any Honda sites. Honda from the factory is defective. Take a look at the Fast Lane Trucks (Taco, Frontier, Colorado and Ridgeline comparison). They show a 2016 ridgeline going on a trail with a small incline. With less than a mile, the trans temp goes to max!
Honda is all plastic.
 
I'm not so worried about the radiator's cooling capacity/performance. I'm more concerned about oil cooler design and I'm betting they use the same design for both the Ridgeline and 100. The dimensions are likely different though. The thread is focused around the Strawberry Milkshake of Death (SMOD).
 
If truly built in Canada and thicker I'd be swayed in that direction. I'd try it out.

But keep in mind, Denso is one of our most reliable line of other OEM products in the 100's.

Update here (want all info to be correct and up to date).

Just got my radiator today (took 12 days from the time I ordered it.). Grrrrrrr!

Seems the Spectra brand radiator(s) are now made in China, just like the Denso.

It looks well built, but I will compare it to the OEM when I take it out. Will report back on fit and function.
 
Due to a dealership repair by the PO where the tranny oil college inlet nipple was smashed, brand new Denso radiator for the LX. Way cheaper than the OEM, which is also a Denso:meh:
 
Denso is made in Taiwan.
 
OK, new radiator is in.

Went with the Spectra instead of the Denso. It was an exact fit. Identical (visually) to the OEM I took out. Everything in the right place, dropped right in, bolted right up. Just need to go test drive it.

Spectra (CU2282) for 99 LX 470.

Update: Radiator has been in for over a month now. Seems to be doing a good job. The real test of course will be this Summer when the radiator must perform in the sometimes brutal Texas heat.

Will report back then, but the Spectra (thus far) does seem to offer another choice...besides the Denso unit.
 
After reading that 7 page ridgline owners thread I think I'd go with the one with the best fluid isolation. I don't think it matters one bit which one you use if you just get a new one every few years. Those honda dudes are fanatical in that thread. Edit,,, 9 pages
 
Has anyone used a Mishimoto Radiator?
They’re about $260 on amazon. Lifetime warranty, don’t know how it compares to oem.

Mishimoto makes a good product, I used one of their coolers on a previous vehicle and their customer service was great when my kit was shipped with missing pieces. I’ll be adding this to my list...

From reading the description seems like it’s OEM style.
 
Fyi Mishimoto only offers a fittment option for 98-02 models.
 
I put a TYC 2282 in my 99 LC three years ago and it is still working great! I ordered it off of Amazon and it was actually a Koyo radiator. The only caveat would be is TYC is still shipping Koyo or are they now sourcing them from another manufacturer.
 
You can open it.

Amazon is great about returning those.

I have received two of those damaged from Amazon. They gave me credit as soon as it was scanned when I shipped it.

It is hard to get one shipped from them that the carrier doesn’t damage the radiator.
 
So many recent reports of failing Denso radiators has me considering other options. With the internal leaks, and tank splits it's not worth the risk to install one until the reports of these early failures subside. I asked a parts counter seller ( national chain) if he had seen any Denso radiator issues; he smirked and nodded his head- yes. Are the failures a manufacturing problem: lack of a QC step like pressure testing, or poor vendor process, or a packaging problem where the radiator is damaged/compromised in shipping from being handled multiple times from import to break bulk, to distribution to multiple carrier hubs before its eventually tossed on the steps at my house. Who knows for sure. One thing I know, I will not mail order a radiator again unless I know its in bombproof packaging. Too many chances for handling damage between warehouse and my front door. I want to be able to pull it from the box at the parts store inspect and accept or decline.

Being a research nerd, I went back and researched specs and many web posts on several brands & options including OEM. I centered in on the Spectra product because of the price point, 2 year warranty and good initial reports here in the forum on Spectra fitment and reliability. There are two radiator options from Spectra for the 100 series: CU2282 (98-2002), and CU2755 (03-07). Catalog info states CU2755 is a 1 row radiator, vs the CU2282 which is stated as a 2 row radiator. Spec's indicate thickness of the CU2754 is 2.0625" wide and the CU2282 is 1.75". Maybe a misprint? My thought was thicker radiator=more rows so I called tech support to ask. Helpful folks at Spectra, but he admitted that it seems to possibly be a catalog error and couldnt confirm. FWIW I asked the manufacture origin of the 2282, its made by several vendors from 5 different countries, the 2755 one: Indonesia. If there was any room for production quality variance the 2282 would see it first, but the fact that there are few reported issues is a good indicator of overall QC. Another interesting data point is the trans cooler in the 2755 is concentric (long tube type heat exchanger), vs the stacked plate style heat exchanger found in the Denso and according to the specs I saw on rock auto's product description the 2282 is also plate style (9 plates).

None of the national parts chain stores listed on Spectra website actually had inventory, all fulfillment seems is through Spectra's warehouse and DS to the store or customer. FWIW anyone shopping for one, PEP Boys had the best deal on in store pick up on the CU2755: $170.25 after a 25% instant discount ($229 msrp). Thats as cheap as Rock Auto, and in my case the paying local tax for in-store pick up was less than the rock auto mail order shipping charges. Just have to wait a week for it to arrive to the store. Plan ahead.

OEM: Its always my preference, but the price is prohibitive. There are two options for OEM radiators depending on model year.
Part MSRP
Radiator OEM 03-07 16400-50290 $601.80
Radiator OEM 98-02, 05-07 16400-50360 $456.39 (Mexico spec for 05-07)

Weird that 03 & 04 are excluded from -50360, why?? I called my parts guy at Toyota and he asked for my VIN to determine which radiator to choose for my 05, and of course it came up with the -50290 more expensive model. He couldn't tell me the differences only that it had to do with North American spec vs Mexico spec., EPA something or other. What could possibly be different in the more expensive option that would be an EPA mandate wouldn't supersede to the earlier years? I know the earlier models had an electric fan, so maybe that accounts for some minor difference in mounting brackets? Anyway even the discounted price of an OEM radiator is more than 2.5x price of aftermarket so in this case I will roll the dice with Spectra and see how it goes. It would be great to know what the differences are between the two OEM options: tank design, configuration/construction 2row, 3row? , measurements, TOC differences if any etc.
