SOURCE: Temp gauge

the sender for the gauge is on the cylinder head near the spark plug if you unplug it the gauge should stay all the way cold then ground it out it will go all the way hot if that reads like that replace the coolant sensor

My mechanic in our town did a quick computer check. Car computer indicated a low level of antifreeze, he topped it up, cleared all messages off the car computer and said to watch the the heat guage for any further irregularities. I'll keep an eye on it, love the car, great mileage fun to drive.

Assuming the t-stat is good, I'd look at the wiring next. Make sure the connector is clipped onto the water temp sensor/back of the gauge and that the wiring is not chaffed, etc. If that all looks good, replace the coolant temp sensor...they're $20 or so. If it still does it, the gauge is bad.

Well , I know $800 is a big bill , but think of it this way , you got a bunch of new stuff on the car. The timing belt replacement alone would cost someone almost $800 to have done by a mechanic , and if it broke and destroyed your engine how much would that have cost. It's always nice to solve the problem on the first try , but at least it is fixed now , and you won't have to worry about any of that other stuff for a long time.

Thank you for the opportunity. I have a Ford Escape 2001 6 cl and temperature gauge stocks on cold. Today it moves to hot then went to neutral and slowly went to cold again without moving.


Hi Ivette,

Temp sensor/sender units, ussually send a variable earth resistance dependent on temperature, so it sounds like the wiring is broken/rubbed through, causing the sporadic changes due to full earth going to gauge(hot). brocken wire(cold)

But could be a faulty sender just the same, doesnt sound like a thermostat after driving the gauge would still move in relation to engine temp, would start by checking the wiring to temp sensor, also check coolant level and monitor engine temp while driving if gauge is in-op.

Hope this helps.

Won't start key stuck in ignition gas and temp gauge not working


this sounds like something is draining the battery like a bad alternator. if you install a new battery the car will run until the car drains the battery due to a bad alternator or bad wiring, these cars are all electronic so without a good battery you cant open door or start, take a look at battery and if it is low or dead again then have the charging system checked.

Temperature gauge stuck


1) Coolant sensor connections broken - this is the first one under number 4 cylinder, intake side. Coolant temp sensor could be faulty. Test by unplugging sensor, connect a 68 ohm resistor to one of the terminals and ground it to the block. Meter should read 3/4 to max. You might need to probe either wire for the correct one. If the gauge works, the sensor is faulty.
2) If the gauge doesn't work, then either the gauge or its circuit is open - the gauges are wirewounds, so they seldom fail.

Temp gauge is not working


Find the wire to the temp gauge sensor on the block of the engine. Unplug the wire and check your gauge. It should read max hot or cold. Ground the wire to the block and check your gauge. It should read the oppisite of the test before. If it does this then replace the temp sender. Otherwise head up the wiring to the gauge. Rare.

I assume you replaced the temperature sending unit when you installed the aftermarket gauge? You need to put the proper sending unit back in for the OEM gauge to work.

You can find a sending unit here (and a gauge if needed):

2001 Kia Optima over heating


I figured this out and fixed it on my 2001 Optima. Mine was an electrical problem, not an overheating problem. The problem shows up when there is a heavier than normal load on the electrical system. For most of us, this is when the air conditioner is running full-blast on a hot summer day. However, it was also occuring when I ran the heater full blast. The heater running full-blast should have lowered the temperature, not raise it. So I tested the coolant temp while the gauge was showing it overheating. The coolant temp was not increasing, but the gauge showed that it was. It is caused by a bad ground connection. Another test you can do to see if your problem is the same as mine is this. As soon as the engine is showing overheating, pull over, park the car and turn off the engine. Immediately start the engine again and see what the temp gauge shows. If it still shows hot, you'll know you've really got overheating coolant. If it goes back to normal range, you'll know it's just a bad ground connection. Turning off the engine eliminates the resistance in the electrical system that has beeen building up and causing an erroneous high temp reading.

To fix: Either find and clean ground connections throughout the vehicle until it fixes it, or do what I did. A mechanic at the Kia dealer showed me this. I ran a new wire from an empty bolt-hole on the top of the engine to a bolt into the frame behind the engine. I only added a 6 inch wire and a new bolt into the top of the engine. The bolt into the frame was already there, so I just removed it, put the wire under it, and replaced the bolt. It created a redundant ground that prevented the build-up of resistance that caused the erroneous temp reading. It was a 5 minute fix and it has never done it again. Kia knows about this problem and they put out a post to their shops on how to fix it.

Emissions test fail mixture to rich


what i used to do is pour a small bottle of rubbing alcohol in the gas tank....this mixture burns very hot so it will clean everything out thus burning all the gas particles off......i used to do this in a 1988 mustang gt that ran real rich because of performance parts and i couldnt ever get it to pass the tests....also try o2 sensors as well as possibly map sensor if equipped...this could be the problem....
temp gauge not working? check wiring and also check tempature sending unit and block temperature sensor.
