Are you actually overheating-boilover-could be the engine temperature gauge sender acting up or the coolant temperature sensor-

I bought it a couple weeks ago and the toyota dealership said it was something in the supercharger or the block. and it boils over after about 20 minutes of driving unless i turn the heater on high, and it comes back down a bit. could it have anything to do with the supercharger or something else?
