All of the turbo 5 cylinder engine bays are hot. Because the dash temp gauge is programmed to sit in the middle without moving, you will never get a fluctuation under normal circumstances. All you can do is check the actual temperature of the radiator and hoses, but that won't tell you much unless you have another car to ccompare it to.

Make sure the splash shield is under your engine. Many people run over curbs or concrete stops in parking lots and tear them up and just toss them. These are air guides to make sure the radiator and engine get proper air flow.

You should still flush the coolant system and brake fluid. Who knows if they have ever been done. On awd cars, the bevel gear fluid should also be flushed whenever the tranny is flushed.

Keep good track of your tire pressures and rotate the tires at every oil change, you must buy 4 new tires when replacing tires.

Don't get overly concerned about the heat in the engine bay,

How do you know it is too hot? Is there a lot of pressure in the hoses? That is do they feel very hard or turgid? Is the block hot but not the radiator?

If you are sure the engine is running too hot for the conditions of use, has the cooling system been flushed carefully? Is there any air in the system? And is the radiator possibly partially obstructed? All of these would lead to poor circulation - also there might have been some history where a stopleak or other compound was put in and this led to deposits and partial block that remained even after you changed the coolant.

In my experience if the circulation is poor or another problem is limiting cooling, the temp gauge will rise on a long hill climb, crowded city driving, or another stress, then go back to normal when the situation changes.
