Outcome: Black pepper worked its way to find the small leak and eventually expanded and filled the leak.
Conclusion: Flushed out the cooling system and replaced the radiator.
Disclaimer: Don't drink the pepper flavored coolant.
Cinnamon is even better, and it works for your stomack too, it it takes a blowout...
