Best is you can supply us with the codes so we can help in pin pointing the troubled area
Coolant below thermostat temp is an indication of a bad thermostat (open)and need to be replaced

P0128 Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature) Detailed Description
Indicates that the thermostat monitor has not achieved the required engine operating temperature within a specified amount of time after starting the engine.

Possible causes : -
Insufficient warm up time
Low engine coolant level
Leaking or stuck open thermostat
Inoperative engine coolant temperature (ECT) sensor
Inoperative cylinder head temperature (CHT) sensor
WE FIND IT VERY COMMON FOR THE THERMOSTAT TO BE AT FAULT
CHECK COOLANT 1ST
