The best temperature rating for the thermostat on a 1994 Toyota pickup is 190 degrees. This gives a good balance of performance and efficiency.
195
180
180 degrees F.
Engines are designed to operate at a given temperature, without a thermostat the engine will often not get up to the designated temperature. So it needs a thermostat to be sure that the engine will run at its optimum design rating.
If everything else is normal, one way to reduce the engine operating temperature is by changing the stock thermostat to one with a lower temperature rating. This temperature rating is the temperature needed for the thermostat to open which allows the coolant to circulate around the engine.
should be the same temperature as your thermostat rating...generally around 190 to 195 degrees.
This depends on the rating of the thermostat. Any where from 165 to 185 degrees is good.
Depends on car, example: it could be 180 - 195. There is the rating on thermostat
No. The thermostat controls the flow of water through the radiator, not the heating core. Using a thermostat with a higher temperature rating delay the opening of the thermostat (and the flow of water to the radiator) until that higher temperature is reached. This will cause the coolant to run hotter.
The thermostat's main job is to allow the engine to heat up quickly, and then to keep the engine at a constant temperature. It does this by regulating the amount of water that goes through the radiator. At low temperatures, the outlet to the radiator is completely blocked -- all of the coolant is recirculated back through the engine. Once the temperature of the coolant rises to between 180 and 195 F the thermostat starts to open, allowing fluid to flow through the radiator. By the time the coolant reaches 200 to 218 F, the thermostat is open all the way. It preforms this feat because there is wax inside the thermostat that melts at a preset temperature. If the thermostat is rated at 190 degrees F that is when it opens. That is it's temperature rating.
Stay at the factory temp.
Its normal power rating is at room temperature. For a temperature of 75 degrees, halve the rating.
