Water Pump Bypass Hole
Often wondered about this hole on the left side of the pump. I've heard (TPiS) that plugging it (and drilling a .2" dia hole in the thermostat) will keep temps down in the summer. Why is this hole there? TIA

As I stated in the new thread, it is all in the book. If you had listened to the people telling you that the oil pressure switch wasn't a low oil pressure safety device and checked the book, at that time, you wouldn't be irritated with me. It's my fault you have such a hard head?

Did someone delete some posts or something?
Anyhow, no need to start a new thread. The SWITCH is there to power the fuel pump when oil pressure exceeds ~4psi.
Being wrong can get annoying I guess, but the solution is easier than you think.
