1)Do I disconnect the lower hose at the radiator or at the block?
2)Do I take the thermostat out during the drain?
Thanks again, Jim

Lower hose at the radiator (if you can get at it). I think when I did mine I did the lower at the engine and used a shop vac with the air flow reversed to blow air through the surge tank to blow out the residual coolant. I left the thermostat alone.
