+2 on that, it helps to run out the air bubbles.
Smear the bolts with anti-seize to make it easier to disassemble next time and protect the bolts against corrosion.
Regarding the slow warmup at idle: This is common for diesels; they don't produce a lot of heat unless worked, much different than gassers. Might want to try covering the radiator during the winter. You may have seen large diesel trucks running with winter radiator covers for this reason.
Generally mine warms up to operating temp within 2 - 5 miles driving thru the city streets, depending on conditions.
The Volvo water temp gauge is notoriously inaccurate. Mine jumps to midspan within a minute of starting on a cold morning and I know it can't have warmed up that much that fast. There is some sort of signal buffer at the gauge that dampens the needle's movement, making it act more like an idiot lamp.
