Where is the coolant temperature sensor located on a 2000 hyundai accent. the car is giving out good heat but the temp gauge does not go tomuch pass the cold

Check out the videos. Also make sure the fan is working.

Yes this vehicle has one!

There are normally two, one with one wire which is for the temp gauge, and one with 2 wires which speaks to the ECU. The later one is usually near the thermostat housing or in the cylinder head nearby. If unsure, get the part from parts store and ask if they can show the location chart.

car shuts off when temp, gets to normal--- causes: low coolant, failing coolant temp. sensor, air in water pump, failed radiator fan, kinked heater hose, check the coolant temp. sensor first.

If it only overheats while stopped or when driving slowly then check to see if your radiator fan is coming on. If not check the radiator fan fuse, temperature switch, relay, and the fan motor itself.

If it is consuming radiator coolant or is blowing steam out of the tailpipe then consider a blown head gasket as your problem. The engine oil may or may not look milky in color if the head gasket is leaking.

did you install the thermostat pointing in the correct direction? Is the radiator cap in good shape? Check for correct coolant level. The radiator will continue to draw in coolant from the reservior for many heat cool cycles after it has been opened.

And lastly could the temp gauge be reading high? Possible temperature sensor.

The larger of the two is the coolant temperature sensor. The other is the actual gauge temperature sensor. The coolant temp. sensor gives information to the cars computor & when the car reaches a predetermined temperature, the computor changes the ignition timing allowing the car to run at normal operation temperature settings. The temperature sensor gives info to the dash board gauge &/or temp. warning light. The reason you can't start on cold days is that your coolant temp. sensor is stuck in advanced mode & the timing is to far advanced . To remedy this problem change the coolant sensor. Good luck!

time to replace thermostat,coolant not at correct temp

you might have 2 coolant sensors one for the gauge and one for pcm, and if you stop by a part store like autozone they will give you a print out of locations of one or both. did they tell you that you only had one ? ask the part store how many they are showing for your car when you go they will tell you. then find out which one they want you to replace

THE SENSOR FOR THE GAUGE IS ON THE HOUSING THE UPPER RADIATOR HOSE ATTACHES TO.

If the coolant is below a certain level, the temperature sensor will not read anything and the temp gauge will not rise. Replace the cap, and check that you have enough coolant in the system. If this does not solve the problem, you will need to test/troubleshoot the coolant temperature sensor.
