Mike, you may consider waiting till spring, before you install the 180.

Several of us run 180 year-round (including in BC and Alberta) with no problems.

The PCM isn't 'set' for 195, nor will a 180 cause any open loop/closed loop issues.

With a 160, yes. Not with a 180.

Well-written Dex Cool article, Willwren. You're helping to convince me of the evils of Dex Cool. And that'* tough when you've got years of GM-sponsored training that tells you there'* nothing wrong with the stuff! :P

MM, two 1/16" holes will do.

DS, I threw opinion and rumor aside and tried to concentrate only on the physics/chemical nature of the materials. That article, belive it or not, is being hard-hit off my server and is being linked by several other sites now.
