A thermostat rated at 160 degrees F (71 deg. C) just begins to open at 160 degrees and is not fully open until the engine coolant heats up another 15 or 20 degrees (8-11 deg. C) beyond the thermostat's temperature rating.
True or False?
Good information for those that are trying to get their Reeper to run at a constant temperature and zeroing in on a particular temp.
What is really interesting is how one works in the first place. The fact that in that copper area is filled with a wax designed to melt at a given temperature. It is this waxes slow melting rate that makes it perform as it does. And what is the coolest part is that it was designed so many many moons ago and has yet to be improved upon. The basic T stat you buy today for modern vehicles is mostly as it has been for many decades.
