What should the temperature of an engine be?
What should the temperature of an engine be?
Optimum performance, for both economy and power, is achieved at temperatures around 100-107 degrees C (210-225 degrees F). Up to 120 degrees C (250 degrees F) is OK if a decent oil is used, but getting a little warm. Some engine builders believe oil should be kept around 80 degrees C (175 degrees F) to keep things ‘safe’.
What should coolant temp be when car is off?
Thermostats normally open at around 80-90°C and the hose will only get hot once the thermostat has opened. Point is that the sensor is reading fine at low temperatures. I checked the ECU readings and when the engine is off for a day the coolant temperature more or less matches the outside temperature, so it definitely did not drift.
Why does my engine temperature stay on cold?
Reasons Why Your Engine Temperature Gauge Stays on Cold. 1. Faulty Engine Coolant Temperature Sensor. 2. Faulty Gauge/Cluster. 3. Broken Wires to the Sensor Or to the Gauge. 4. Bad Thermostat.
What should the temp be when blocking off the radiator?
Your engine should have a thermostat that opens at 195 degrees. If blocking off the radiator gives you a higher temp, then you can safely assume your t-stat is at fault. It’s letting the coolant circulate too soon/too much, not allowing the engine, and thereby the coolant, to reach proper operating temperature.
What is the temperature of the coolant in an engine?
If your car model has two coolant temperature sensors, one is used by the temperature gauge, and one is used for the engine control unit. Engine temperature sensors are easy to measure with a multimeter, but you need to find the right values of them.
How to check engine temperature after a drive?
To verify the actual engine temperature, check if the top hose to the radiator is hot after a drive. Thermostats normally open at around 80-90°C and the hose will only get hot once the thermostat has opened. Point is that the sensor is reading fine at low temperatures.
Why is my engine temperature reading so low?
The most common problem when it comes to a faulty engine temperature reading is the coolant temperature sensor itself, sending the information to the cluster. Some cars have two temperature sensors, while other car models have one.
