Drove the truck around town last night! Oil pressure seemed to be ok - it varied between 40-45 at start up, then after driving around a bit and getting warmed up, it dropped to down about 25. Is that normal for it to change that much?

My temps stayed steady at 180-190 the whole time. The weird thing - when I got home and started backing into the garage (driveway slopes up to the house), my temps jumped up to 210-215. I think, right before I shut it off, it was getting close to 220. Anyone have an idea why it would do that? Air pocket in the system? When I filled up the coolant, I had the truck jacked up in the front as high as I could get it.
