Look in the front of the vehicle where there is an opening in the bumper. It is located in the bottom opening around the middle of it. It has a plug on connector. I wish I had the part number for you.
i just put in a new radiator and now temperature gauge reads high but their are no leaks
1996 prelude temperature gauge reads low temp
THere are 2. one for the gauge, and one that reads for the fan. the gauge one is located by the firewall, while the other is near the coolant thermostat housing.
Low Coolant or faulty gauge
first let me ask you to clarify. do you mean it reads low temp or that it reads lower then what the banks and the temp outside is???? I have the same problem on my 1998 Regal. The temperature gauge reads ~ 20 degrees lower than actual. Occasionally it will read correct, but not for long. I can't find any information as to where the sensor is, or the supporting cabling that will help me trobleshoot the problem. JJD Not compared to Banks, but actual temperature readings outside. For example, if it is 95 degrees outside, the regal says ~72 degrees. It used to read withing about 1 degree to the actual outside temp, but now it is at least 20 degrees lower. I have a 99 Buick Park Avenue Ultra, and my temperature gage was doing the same thing the dealer replaced the sensor, located on the left front of the radiator. They charged me $80.00, if I had known where and what to look for I could have done it for a lot less.
The outside air temperature should still have the same reading. The installed sending unit should not affect the temperature gauge.
This sound like a bad temperature sending unit mainly located on the intake manifold sometimes by the thermostat housing ,it has one wire plug.
In the gas tank
ambient air temperature is the temperature of your surrounding air. if you stand outside with a thermometer, and it reads 64 degrees, that is ambient temperature.
you could have abad temp sensor
More than likely it is because it is in different conditions than the official weather stations thermometer. An official thermometer is in the shade and has air circulation. This is how an official temperature gauge has to be set up. The temperature reading from your car could be higher for a number of reasons, partially dependent on where the thermometer sensor is located. It could be in direct sunlight, near the engine, or if you are on pavement it could be receiving ambient heat waves coming off the pavement. All three of these things could increase the temperature reading of your gauge.
You might plan to refuel when your fuel gauge reads one-eighth of a tank of gasoline. Some people choose to refuel when the gauge reads one-quarter of a tank remaining.
