buy a thermostat
That's good advice. The older ones used a 180, while the newer ones used 195. They all run better at 195, as long as the cooling system is in good condition. The higher operating temperature is more efficient, but needs a good 16 psi at the cap to stay below boiling point.
If it stays below 210 even in the worst conditions, the thermostat is not necessary. However, it takes longer to warm up on a cold day without one.
195 to 210 degrees is NORMAL operating temperature.

A thermostat is a temperature sensitive device used in a vehicle's cooling system to control the flow of coolant between the engine block and radiator. A thermostat is important for several reasons. 1. It helps allow the engine to operate at optimal fuel efficiency. 2. It allows the engine to reach optimum operating temperature quickly. When the engine is cold, the thermostat stays closed, allowing the engine to reach operating temperature quickly. Once the engine approaches a predetermined operating temperature (typically 180-220 degrees F.), the thermostat begins to open and allows coolant flow from the radiator to the engine. Mainly it serves as an emission control device by allowing internal engine temperature to remain within normal operating ranges.
The thermostat in a car regulates the coolant temperature inside the engine. When the engine is cold, the thermostat is closed, allowing the heat from the combustion chamber to heat the fluid (coolant) in the coolant galleys in the engine block. Once the engine reaches an optimal temperature, the thermostat opens, allowing coolant to flow through the radiator. The thermostat then controls the flow of coolant to hold the engine at its optimum operating temperature, irrespective of engine load and operating condtions.
A thermostat on a vehicle opens at a preset temperature to allow coolant to flow from the water pump through the radiator and engine block to cool the engine. They are set to open around 185 degrees. This allows the engine to heat to operating temperature relatively fast.

On the engine block, near the thermostat housing.
Don't know if this is normal or not, but was playing with new OBD software this afternoon and engine temperature was 90 deg C. Sitting in yard and a couple of 5 km trips around the block.
On the engine block, near the thermostat housing.
The thermostat is located in a removable housing at the engine end of the upper radiator hose Drain about 1 gallon of coolant from the radiator Remove this housing Note how thermostat is installed Clean both surfaces Replace thermostat and gasket Re-install housing Re-fill coolant slowly to prevent an airlock Start engine and look for leaks Run engine to normal operating temperature with heater on Re-check coolant level
Either there's a problem with your sensor, or there's a problem with your thermostat, and it's giving a false reading. Your engine temp may actually be high, as well - what you see on the gauge is the temperature of the coolant, not of the block itself.
