Have any of you tried a universal radiator like summit racing etc ?
My C5 is high a high mileage lower budget ride.
spending a grand vs $300-400 is worth the research.
If you have a pinhole leak in your radiator, these ACDelco seal tabs worked for me. My wife has a 67 Nova with a 525 HP LS 376 crate motor with an aftermarket aluminum radiator. It had a pinhole leak in the radiator and I used these tabs and it fixed it. Sat in 95 degree bumper to bumper traffic with it, got it home and didn't leak or lose pressure in the system. I read that GM uses these tabs in all cars from the factory but was able to confirm it. It's been three months and still no issue.
