Here's the thing I already stated previously: my water temp would climb when in the garage. Faster the further in I parked (or if 'stuff' was in front of the car). I could let the car roll in neutral back into the driveway and the water temp would fall.
This is from memory, and a different engine ago, but I recall seeing as high as 212-215 in the garage, but it would fall under 206 in the driveway.
Going from 210-220 in an enclosed garage vs outside is within that same order of magnitude.
Is real experience good enough? ;)
