Another question from me

My rs never overheats, the temp is pretty stable, but, the under bonnet temps are stupid, even the slam panel gets hot, thats off a normal, short run, am pretty sure they shouldnt get this hot?

I have added some bonnet chocks, raised it up around 1", but its still pretty hot in there, wondering if there is anything i can check or replace that would make it cooler?

Where is the thermostat on these? thinking about changing it, just incase.

Also, people talk about charge temps, how do you get these? is there a gauge & fitting kit i can use? where do you get the reading from?

Cheers
