My theory is that if we have the fluid flowing then the temperature will only go down after the engine is off and not up at all from where it was at before the engine stopped.
Again, I go this way just because in my case the front and rear o-rings were not the same two times and always the rear one was different. Although eventually both will get squared I just think heat is one of the causes.
I know we don't 'fix' the M62 flaws here but I find the discussion interesting though.
I am curios how many people found differences between these four o-rings.

Right, it's through the cabin but the fan is also running which will help dissipating the heat.

When I replaced mine I found the same condition you mention - fronts round, back square. I've been following this discussion and agree that the back of the engine temp stays higher (and longer) than the front possibly from it being so friggin tight back there allowing very little air circulation to dissipate the heat.

fmugur - is there a way to have the secondary fan come on for a predetermined amount of time; say 3-5 minutes after shut off with the GT1?

I don't know. Maybe terminator or Slick would know but without running the auxiliary water pump just the fan wouldn't help much. I am looking into it. I will try a few options this week and report back.
