Ahhh. I wonder why the last one I put in didn't do this? Got em' both from classic parts. But I'll do that. I've got the thermostat pulled out, brought it in and checked it in a pan of water on the stove with the help of my wife's candy making thermometer. It opened up right before 180*. Now I've got the radiator out to pull the old pump and put in the new one. If I'd have gotten back on here earlier, I would have just tried drilling the hole and saved the water pump. But I've already got two bolts out and the radiator, and horn out of the way. I'm not going to put it all back together now, especially since I know the thermostat is good. But thanks for that info. I know I've heard a lot of talk about that bypass hole before. Didn't even think of it till you said it. Now I've got to post again to ask about the fan bolts. They're not left-handed threads, are they? I'm having a hell of a time getting one loose, so I came back in to check with 'the guys' to make sure I don't ruin them by forcing them the wrong way. Be back in a bit to see if anybody knows.
