Epoxy Curing, Pressure Test, and Addressing Root Cause

What happens here

The presenter returns after 24 hours, allowing the epoxy to fully cure. He then performs a "hillbilly pressure test" by plugging one end of the radiator and filling it with water from a garden hose. He checks the epoxy-repaired area for any signs of leaks, confirming that the epoxy has created a successful seal and is holding water. He then proceeds to tighten the loose bolts that caused the initial damage to prevent future issues.

Goal: Verify the epoxy repair and prevent future damage.
