Pinhole leak in radiator

[DblDuce]

I have a 1990 Granville Debonair class c motorhome. Based on the chevy G30 350 ci chassis. Discovered a pinhole leak in the radiator about 2 years ago. Have tried adding bars leak to it and it seemed to hold up, but is now eventually leaking a bit again when its pushed/under load going up hills, etc. Thinking about replacing or fixing the radiator, but not sure how to proceed since the company is no longer in business. Would I look for a radiator to fit a chevy G30 Van, or take it to a radiator shop and see if its something that can be fixed? it doesnt leak very much, and i dont want to put more than $500 in it to fix it, as i can live with it the way it is before putting more money than that in it, since i only put a few hundred miles on it a year.

Anyone have any suggestions?

FWIW. I recommend getting estimate from a radiator shop

there should be a metal tag on one of the tanks.With this number you shoul be able to sheck aftermarket sources for a new radiator

While it doesn't get the same mileage as an RV, I used some JB weld high temp epoxy putty on a small leak on my classic car's radiator.was still holding up strong when I sold it. May at lest be a short term fix while you source a replacement. I feel that those internal bars and solutions can do more harm then good long term good luck
