Best way to tell your normal operating temperature is to visit an auto parts store and ask them what the OEM thermostat temperature is (or you can look it up yourself on Autozone.com). Most cars these days will have around a 190 degree thermostat. Your car will run slightly hotter than that temperature as it is needed to maintain the thermostat in an open position. With that thermostat you can expect to see the temperature of the water stay around 205-210. If the water temperature ever starts to get above 240 you should shut the engine down to avoid damage and have the cooling system checked. Temperatures above 260 WILL cause significant engine damage.
You run it until the engine reaches normal operating temperature on the temperature gauge this way the oils viscosity will be correct. on colder days you need to run it longer.
The normal operating temp for any Mercedes is between 80°C and 100°C (the next line after 80°) Anything over 100° and you should have it checked out. Mercedes are different, in that, the temp gauge is constantly moving because it provides true engine temp data... not just (normal) or stuck in the middle of the gauge.
The normal engine temperature for a semi-truck typically ranges from 180°F to 200°F. It may vary slightly depending on the specific make and model of the truck. Monitoring the temperature gauge regularly is important to ensure the engine is operating within a safe range.
Sounds like it could be a bad thermostat - not closing to allow engine to heat to normal operating temperature
lets you know from inside the car if your engine is running at the proper operating temperature.
We replaced the temperature gauge in my 1991 Chevy blazer what is the normal operating temp?
Just to the left of the engine temperature gauge , at the center of the normal operating temperature range . It is a symbol of a person wearing a seat belt with a circle in front of them
The gauge on the far right side of the gauge cluster is your engine temperature gauge. The normal operating temperature is at the half-way mark. If the needle raises above the 3/4 mark then the car is overheating. A light will come on also if it begins to overheat.
It sounds like your temperature sender (on top of the engine) is faulty allowing it to earth out, or the wire going to the sender may be touching a earth.
To check the engine temperature in a Citroën Saxo, you can monitor the temperature gauge on the dashboard, which typically indicates the coolant temperature. If the gauge is in the normal range (usually around the middle of the scale), your engine is operating at a safe temperature. Additionally, you can use an OBD-II scanner to read the engine temperature directly from the ECU if you're looking for more precise data. If you notice the gauge approaching the red zone, it’s important to stop the vehicle and check for overheating issues.
i just put in a new radiator and now temperature gauge reads high but their are no leaks
Between 180 and 210 degrees. It is safe to operate an engine normally above about 112 degrees. Before it gets to that temperature you should be soft on the accelerator. The red zone on the temperature gauge is usually around 240-245 or so. Getting the engine that hot can be harmful to it.
