I started with a 160..thinking that a lower temp would help avoid overheating at slow speeds.

Having learned that MORE engine wear occurs at the lower temps,
(I knew that, but thought overheating and puking was too embarrassing).

I then replaced it with a 180 from NAPA.

Strange but my water temp constantly fluctuated from approx 175 - 200. I thought of the wear issue and thought...this CAN'T be good....so

I replaced that one with a 180 "Robert Shaw" thermostat and this thing holds steady at 180!

I'd go with a 180 degree Robert Shaw!

Bob P,

I've heard of the hole trick...and it seems to make sense...why wouldn't thermostat manufacturers incorporate this?
