well first off theres nothing wrong the engine temp... built up to 90 the thermostat opens now the hot coolant going through the rad also provides the water to the heater matrix a small radiator behind youre dash now theres more hot water being taken away from the main rad... as you are only idling still so with the fan on 3 or 4 its basically taking all the heat out of the engine to maintain the interior temp.

thats why if youre car was overheating youre advised to whack the heater on full blast by taking the heat out the engine the coolant wont be as hot the thermostat will then close again to maintain it its normal you didnt even need a new thermostat it is working as it should youll notice that the heater isnt as warm because theres not a great deal of heat when idkling once you start driving the engine temp will go up the pump will work faster the jheat will build up again so simply youre worrying about nothing and wasting money for nothing every car does it mate
