You need to look at the temp sending unit it's probably faulty anthor issue with volvo is dirty throttle body's this raises havoc on the car they idle up down all over the map also you should change the thermostat too as a precautionary measure make sure it's the right temp for your year of your car thanx Chris
The C/F format for the outside temp display (on rearview mirror) can be changed by depressing the switch for an extended period (Instructions are in the owners manual, page 2-54). The inside temp C/F format (on the automatic climate control) is changed via the "English/Metric" selection on the DIC.
All that. The mechanic should have put your truck on a computer that will read what the temp is. It would have probably read that your truck was running at normal temp. You could have had a thermostat that was stuck partially open causing a lower than normal reading. temp gauges should read about the halfway mark. Seeing how you have a 180 t stat, your temp should be from 170 to 200 this is normal. Find another mechanic, I think you may have been taken.
TEMP GAUGE SHOULD STAY IN MIDDLE.IF ITS MOVING UP A LITTLE CLOSE TO RED.CHANGE THERMOSTAT AND RADIATOR PRESSURE CAP MINE RELATIVE CAR DONE THE THE SAME.I REPLACED THEM BOTH -.WARNING IF ITS YOUR FIRST TIME LET A GARAGE DO IT BECAUSE YOU GOING TO HAVE TO TAKE THROTTLE BODY OFF.TO GET TO THERMOSTAT.THEN COOLANT SYSTEM IS GOING TO TO BE BLEED.TO KEEP ENGINE FROM OVER HEATING.IF YOU BEEN USE TO WORKING ON CARS. ALL IS GOOD.
The temp sensor known as the engine coolant temp. sensor tells the computer if the engine is overheating and so forth and tells the injectors how much fuel to give the engine. The temp. sending unit is what controls what your guage reads. It sounds like you need the temp. sending unit. It located near the thermostat housing with a single pole connector.
