QTO4842ANAX SN 5981027 installed in 2010 and has 103 hrs.

Radiator leak discovered, a pinhole in the core peeing out coolant while running (shut down on low coolant).

The radiator is the Russian made unit marked CPL-70.1301.100-2

Looking for recommendations on a path forward.  This is on my home so I have some time until hurricane season.

Do I go back with OEM?  I'm not really wanting to get another part like this one if it failed with only 103 hours.  My pro on a previous visit told me the metal on these radiators was real thin.

Is it worth having this radiator repaired if it's just a pinhole leak?

Are there aftermarket options that are better?

Thanks in advance for recommendations.

If you can find a good old radiator shop with torches and tanks and such that is the way to go.

Tell them to repair the problem and look for any other issues and you can use this opportunity to have them install an American style filler neck if it doesn't have one already.

A good shop should be able to make it better than new.  Also a replacement will usually be very expensive.

The radiator should be repairable but the pinhole may be the tip of the iceberg. If it were mine I would remove the radiator and solder it myself. They are built with a light gauge brass. I would also measure it while you have it removed and start searching for an aftermarket radiator. Next option would be having a shop re-core it with better materials.

I have found that the best thing to do is go to a reputable radiator shop and recore the radiator.  I can tell you I have done this on a couple different units and the re-cored radiator weighs about 50% more than the original.  Those Russian radiators are very thin from new.  It will probably cost less as well.

Thanks for all the advice.  I plan to have my pro remove the radiator (if their shop will do that king of work for me) and then bring it to recommended old timey radiator shop nearby that can fix/rebuild anything.  Regards

One more question, has anyone tried an aftermarket radiator from BGR?  They list a part number OF2008a replacement but don't give weight or price.

I have had no experience with BGR.

I have found that NAPA is very good at replacement. Bring your old one in and they will match it up. Usually all I need to do is have radiator shop remove mounting brackets and threaded port for coolant level probe from old radiator and install on new radiator.

So do they just use the dimensions of the core or do they come close with the tanks and outlets also? Napa is my go-to parts house especially for my 1957 Chevrolet two ton truck.

Yes. I drop it off and my NAPA guy matches it up. Everything is the same. I did use one on a older model Generac that matched the same ( replacement fit a 1967 Ford truck ). The only difference was it had the inlet and outlet for the automatic transmission lines but I just left them plugged. No problems and it has been 2 or 3 years now. I do all the maintenance and it runs fine.

Thanks for the info Genman, I was thinking that they were specific to Generacs needs.

I agree the Russian radiators are junk. Have had more than one rebuilt. They removed the mounting brackets and built a new one. Another plus is you are getting rid of the Russian radiator cap
