You might be low on enigne coolant. When air passes by the temp sensor, it will read higher and then read lower when liquid moves past. I would make sure your coolant is at the correct level in your radiator overflow tank. If not, fill with 50/50 Prestone engine coolant. When the engine is cold, remove the radiator cap and look in the radiator and fill it up if needed. I would then replace your radiator cap with a new one. When they get old, they can cause you to use fluid over time. The rubber does not seal as well when under normal 6 to 8 pounds of pressure. Please do this when the engine is cold. These can be very dangerous and burn you when the radiator is hot. Note, the cap is like a child medicine cap and has to be pushed in when removing them. Just turn it counter clockwise until it reaches its stop, push in and turn it some more and it will come off.


I hope this helps you.

Changed out water pump and thermostat and vehicle runs high temperature what could be issue?


Reasons the Temperature Gauge Reads High

If the temperature gauge reads high, it could mean your engine is overheating. Another reason your reading might be high is you could be losing coolant. A small leak or evaporation may cause your radiator to slowly lose coolant. A third reason your temperature gauge reads high could be because the thermostat is broken. If this is the case, you may need a coolant temperature switch replacement. The last reason the temperature gauge could read high is because of a water pump, or water pump gasket failure. If the water pump is malfunctioning, it may need to be replaced by a professional.

What to Do If Your Temperature Gauge is High

If your temperature gauge is reading high, it means your car is overheating. This is a very serious matter and you should never drive an overheating car. If your car starts to overheat, shut off the air conditioner and open the windows immediately. If this does not reduce the overheating, turn on the heater as high as it can go. If this still doesn't work, pull over on the side of the road, turn off the engine, open the hood carefully, and wait until the vehicle cools down. Never open the radiator cap while the engine is hot - coolant can spray and burn you. Once the vehicle has cooled, take the car to a mechanic right away so they can diagnose the problem. Cars are especially susceptible to overheating in hot climates, like what's common in cities like Los Angeles, Phoenix, Las Vegas, or Atlanta.
The temperature gauge is an important tool in your vehicle that shows the temperature of your engine's coolant. Contact YourMechanic and have your car inspected for overheating if it reads too high, as this can cause serious problems...

Reasons the Temperature Gauge Reads Cold

On most vehicles, the temperature gauge reads cold until the engine has run for a few minutes. If the temperature gauge still reads cold after the engine has warmed up, the gauge may simply be broken. Another reason the temperature gauge could read cold is if the thermostat in the vehicle stays open. With the thermostat stuck open, the engine can be overcooled, causing a low temperature reading. If this is the case, the thermostat may need to be replaced.

Double check the thermostat and make sure the water pump is doing its job. To check the thermostat, simply take it out and reassemble the housing with out the unit. Run the engine and hopefully it will get warm to hot. If not check the pump.

The temperature gauge reading of my nissan admax 2001 model is always too high. but im not experiencing overheating. what do i do?


If your temperature gauge is reading too high, it can only be one of two things: The engine is overheating or the gauge is "lying" to you. I would recommend first taking the temperature of the cylinder head with an infrared thermometer to determine which one it is. If the engine is actually as hot as the guge says it is, then you need to check your cooling system. If the engine is not as hot as the gauge says it is then you need to diagnose and repair your gauge circuit. (most likely an inaccurate temperature sensor)

What's chances that the temperature gauge or sender itself is wrong?
Is the heat exceptionally hot? What temperature is the heater dicharge when the gauge reads 260?
I think that the sender is not expensive, try that. An auto parts store could get you an inexpensive dial gauge that you might be able to install in place of the sender.

Even though my truck is not overheating, the temperature gauge will shoot up to hot and the oil light will come on. After a few minutes, the truck will not let me accelerate anymore. If I shut the truck off, it will reset the oil light and the temp gauge and run fine for a while. But eventually, it will do the same thing again. Is it a sensor or computer problem

Seems to me it's the engine coolant temperature sensor or the connecting wire to it. Some Model/Year (MY) hyundai's have TWO (2) temperature sensors.. one for the instrument panel/gauge, the other strictly used by the ECU (Engine Control Unit)... if this sensor goes bad, it sends the wrong data/signal to the ECU and this can affect engine performance.

Overheating


Is the car actually overheating? or is the gauge reading hot, but the coolant is fine and not bubbling over. Why? because my gauge kept reading hot, then I checked everything and all was fine. But the gauge continued to read hot. Then I replaced the resistor in at the bottom of the dual fan assembly ($50 part - installed myself), that that would solve it... nope! still read hot at various times... finally just gave the dashboard a good bop and the needle went back to the correct position. Try it.

Dash Temp Gauge reading extremely hot


You need to pressure test the cooling system. If it holds pressure, I would look at replacing the water temp. sensor. If it doesn't hold pressure, you have a coolant leak going on. If you don't see it dripping on the ground or inside the car, I would be suspecting head gasket problem.
