When my car has been on a run after about half an hour I can smell warm coolant inside the car through the heaters.

My experience with this sort of symptom is that the heater core is leaking, or related one of the related hoses/fittings is leaking.

Are you able to notice any steam inside the vehicle under the dashboard?

Hi, there's no steam or anything and my coolant level stays the same but the engine feels really hot after half an hour.

Well, the safe thing to do here is to have your coolant system pressure tested. You can do this yourself if you have the right tools.

See this link on how to do it:
