Punctuation is your friend. Comma's can be used to break up sentences, and make them much more reader friendly.
Anyway, how old is your thermostat? Is it working correctly? Otherwise, take it to a radiator shop, and get them to do a check of the system, mainly sitting it there with a thermometer in the radiator, making sure that the thermostat operates as it should. You can also simulate this with a pot of boiling water at home. However, at the mechanics/ radiator place you can see how your guage reads in relation to the real temperature. If it's too far out, you may need another temp sender, or a new guage.
