Default Running warmer than normal

Hi,
I had my radiator replaced in my 2005 RX 330 due to over heating and a crack but now it’s running warmer than usual...any suggestions?

Was the system "burped" of air during the flush of coolant? Also how old is the T-stat?

Hi,
I believe the correct coolant was put in but I was also thinking it could be the thermostat. Will be taking it in this week.

Normally of there was suspicion of overheating, one of the things that should be checked is the thermostat. Weird that they did not get to the root cause of the overheating, or perhaps I am mistaken.

Happened to my wife's 08 RX 3 years ago at ~100K miles, had to replace both the Coolant Temp Sensor and the thermostat. No problem ever since.
