Going to change the thermostat tommorrow, I don't think it's working properly. Ended up getting a Stant Super-Stat from local auto parts store and also picked up a waterneck gasket. My question is, how should I go about this. Do I have to drain the radiator? From what I can tell I just take off the upper radiator hose from the water neck, unscrew the water neck. Clean off the waterneck, take out the thermostat and replace it with a new one. Put a fresh gasket on the waterneck tighten it down and reattach the upper radiator hose. That sound about right or am I missing something? Also, this thermostat doesn't appear to have a hole in it, i keep reading about this. Anyone want to elaborate on the installing of the thermostat issue so I don't **** something up. Appreciate it fellas.
