I have been putting together a small generator from parts I have acquired. The engine is a Kubota EA500-N.
I built a new frame and installed a Leece Neevel to charge batteries at our off grid ranch.
I thought I had all of the bugs worked out....oil leaks...bad seals but wouldn't you know it all of my test running a getting all just right before I was going to commit it to the wilderness and I have developed what appears to be a leak in the radiator. I am not sure if it is the radiator itself or the seal where it mounts to the engine block. I took it off and it appears someone else has also from the new silicone on the radiator where it mounted to the block. No soldiering has been done on radiator. I know many guys toss the radiator. I will do the same if this one is dead. Before I do that and all of the work involved I am looking for suggestions on how to check this style radiator. The coolant appeared to be coming from the tubes but in reality it was everywhere. It is well built. Any suggestions on how to find a bad tube?
Now if it can't be fixed what is the proper way to make a plate so an external radiator can be added?
