Excellent find (the D24-savvy Volvo-trained mechanic)! Great to hear you got it running better than before and no damage was done. Don't lose that mechanic!

Excellent plan. These engines have plenty of exterior coolant hosing that is susceptible to failure which can end catastrophically if a major loss of coolant occurs quickly. That low-coolant level alarm is the best insurance. I'm going to do similar on mine, planning to wire the alarm lamp to one of the unused lamps along the bottom row of the instrument panel.
