Check the gauge by removing the wire to the sender unit and shorting out on the head . If it goes straight to hot then replace the sender unit ( the one that has one wire only to it.)

I have a 1988 Mazda 626. What are the correct resistance values for the temp. gauge sensor at various heat levels? The official service manual doesn't give them. Thanks.

The Autodata fuel injection manual provides those figures for the engine management temp. sensor and I think I have seen them in the Haynes repair manual.

The temp. gauge sensor values I have never seen because it is generally accepted the electrical temp. gauge isn't a gauge but an indicator and therefore doesn't need to be accurate.

If you had the correct figures it is a bit of a faff suspending the sensor and an accurate thermometer in cold water and heating it slowly and monitoring the temperature and resistance. Mostly a replacement sensor is so inexpensive it isn't worth the effort.

Ford used to supply different sensors so the gauge (indicator) could be calibrated more closely - so it was around halfway at normal working temperature, but Ford seemed to be the only one that needed calibrating...

In the case of incorrect reading that isn't corrected by a replacement sensor, the supply voltage to the gauge should be checked to ensure it is being regulated accurately to the correct voltage - I know of only two standard voltages (10 volts and 5 volts) but there might be others.

How do you read the temperature of engine. Thanks

There are several methods. You can use the dash gauge but it is not accurate. The other ways are to use an infrared thermometer, an OBD reader, or manual gauge in the coolant

Temp gauge not accurate

Sometimes bad temperature readings can be corrected by cleanning ground connections at the battery, chassis ground, engine ground and instrument cluster ground.

Temperature display isn't accurate

Hi Dale. Look under the front bumper either on the left or right trim panel. The trim panels are triangle in shape. An outside temp sensor usually sits in this area. The sensor may be missing. BMW has the sensor, wire, and connector available sperately if they are missing or damaged. It will cause the outside reading to be -40 and can cause the a/c compressor not to operate.

After i turn off engine it sounds like boiling water but temp gauge reads cool and no water leaks out

I would recommend checking the coolant level in the radiator while the engine is cool. If the coolant level is low, the temperature gauge will not function properly and can read cool even though the engine is actually overheating. The cooling system should be checked for proper operation using a scan tool and an infrared thermometer to verify that:

1. The thermostat is opening at the correct temperature
2. The coolant is flowing through the radiator correctly
3. The engine coolant temperature sensor is providing accurate data to the engine control module.
4. The electric radiator cooling fans are turning on at the correct temperature

If there are any problems found by checking the 4 items listed above, further diagnosis may be needed to locate the actual CAUSE of the problem.

Needle on temp gauge stays on hot

if the temperature gauge never moves its probably just the coolant temperature sender. Replace that. but i honestly recommend buying a new temperature gauge with more accurate readings. they arent very pricey and they are easy to install

Temperature gauge reads that it is overheating but the engine is always at operating temp and the thermostat is already replaced. when turning the ignition on the guage automatically goes hot and climbs...

It certainly could be the sensor and it is mostly cheaper and easier to replace it as a first step.

Bear in mind the temperature gauge can only be reasonably accurate if it is supplied by the correct stabilised voltage and sometimes the instrument voltage stabiliser does cause problems...

Gage reads 10-50 degrees below actual tempiture

The needle on the dash gage can be pulled off and slipped back onto the stem of the gage. First get an accurate temp gage to be sure what the engine temp is operating at. Then remove the face of the dash gages and remove the needle and place it back onto the stem to reflect the current correct engine temp and you should be good.
