Re: 5/8" heater core hose blowing off!!!

If it were mine:

- run a stock thermostat, no drilled hole (if it needed it, GM would have drilled a hole)
- get the cobbled together fittings and metal hoses off of there, and run straight rubber with one good stainless worm clamp on each end

I bet the hoses will stay in place.
