I just got my 2000 v70 wagon back from the mechanic. I originally took it in because it was stalling and he replaced the temp sensor. I got it home and it leaked coolant all over the driveway so I took it back next day and he said he forgot to replace the gasket ( ideot) on the way home stalled again. It also seems to take forever to heat up temp gauge slow to move too.
Any suggestions????

 

I would bet on that sensor being possibly bad. Was it replaced with a VOlVO one or aftermarket? Also when was your thermostat last replaced?

 

Not sure when thermo was changed bought used in june of this yr. Not sure either about the sensor but will ask. Can you think of anything else to try?

 

Since you don't know when the thermostat was changed I would do that ($12) and check on the sensor. I personally use the VOLVO blue box parts for sensors.....but that's just me
