It could be a number of things:

  1. Not enough coolant, check level. If it´s missing some see if it holds level now or if it losses coolant.

  2. If something was done that required a drain of the cooling system, it may not have been bled correctly after refill and have some air-bubbles in it.

  3. Thermostat may be broken, replace, refill, bleed system.

  4. Water pump may need replacement. Did you stick to the recommendet change interval?
