Question on Radiator connections

Are you gonna have the valves adjusted as well?

The whole point for me was to reset the MM before the 15% to skip the B4 since I do not plan to change the TB until at least 120K. I guess now it's too late and when I do my oil I will be resetting all those codes. My valves are not super quiet or noisy, we will see.

If get to clean and restore those washers Ill post pics, most likely I will replace the cooling fluid or at least 1 full gallon once I either replace the radiator or fix the washers.

Just wanted to upgrade the thread...I had a mechanic friend of mine install the new radiator with the honda coolant on sunday. I asked him if he knew about the issue and he said yes but it varies with manufactures and various radiators and the materials used etc. He also said that unfortunately with those connections its not a matter of if but when that trouble will arise. But im glad that its done and I have peace of mind.

So does he think the problem will eventually recur with the Silla? All I could see from your photo was that the washers appear to be anodized.

To be honest I did not ask him if he thought there would be an issue with the silla washers eventually down the line. I was just happy to have it replaced haha. He simply said that if one intends to keep the vehicle for a long duration its certainly good to be proactive just encase something were to occur. I did ask him if it was strictly an import issue and he said that he had seen the same problem in some GMC's but did not specify the years.

Ok, thanks. That's what bugs me about this is that these replacement radiators all seem to be "OEM replacements" - it's hard to tell if they'll be any better or not.

From what I have read I believe Denco makes OEM replacements for honda which uses the same exact washers etc and Koyo and silla make aftermarket ones which differ. I guess people who have replaced theirs (from what I've read here) have gone with either silla or koyo.

From what I've gathered, the koyo and silla designs and materials used are very similar to those found on the odyssey. This issue seems to be a non-issue on the ody from what I've read. I do know the fittings on my silla are not simple steel. They are either brass or an anodized steel. Either way, I have full confidence the silla will last as long or longer than an OEM replacement. You also have to think this: if the OEM lasted for 5+ years, an OEM replacement should last that long as well. One would have 10+ years of ownership before this would ever be a concern again.

The radiator shop that changed mine out in Portland said that I'd not have the same problem with the radiator he installed last year. He's seen a lot of them in the last 35 years and said that the one he puts in won't have those problems.
