You need to find out if your thermostat is stuck open, there's a way of displaying the OBD coolant temp on the dash if you have a search, that should tell you whether the thermostat is working.
If the thermostat is fine, next thing I'd look at is coolant level, too low and it doesn't reach the matrix.
After that I'd remove the matrix (easy job) and either replace or clean it out.
All my own opinion, if anyone has anything else to add I'd welcome it
