Where is the temperature gauge on a GM Truck?
Temp. gauge on dash stays completely at the far left/bottom. On startup (when key turned to start) the guage will briefly peg out to far right, but returns to left as soon as engine starts. checked coolant level (Overflow reservoir was empty, so I filled it to the “cold fill” line.
What causes an engine temperature gauge to stay on cold?
Reasons Why your Engine Temperature Gauge Stays on Cold 1. Faulty Engine Coolant Temperature Sensor 2. Faulty Gauge/Cluster 3. Broken wires to the sensor or to the gauge 4. Bad Thermostat 5. Corrosion in connectors 6. Air in the coolant system 7. Broken engine control unit
What kind of thermostat does a GM Truck have?
THe 195’s were Duralast and Valucraft. The 180 a Duralast and the 160 a Valucraft. I checked both the 195’s in a pot of water and they both opened at 195. I eliminated the possibility of a bad thermostat after that test. I checked the Serpentine belt to make sure it is correct and it is.
What should the radiator temp be in a GM Truck?
The radiator did not get hot though. After several minutes the temp gauge indicated a steady decrease in temp down to about 170 and then back up to about 240 and after several minutes the temp came back down to approx 200 and stayed there.
Why is the temperature gauge on my Chevy truck not working?
All I have the same issue, I own a 1996 chevy pickup c1500, before I replaced the temperature gauge sensor, the gage read two lines below 210, after I replace the temp gradually climbs but the engine not as hot as where the gage reads, need advice stephan is on point for the diagnostic procedure. First.it’s not a thermostat issue.
What was the head temp on my GM Truck?
I monitored the temp at the intake manifold next to the thermostat housing and it was initially about 130 degrees when the head was indicating 230. The head temp increased to 240-250 and after several minutes the intake climbed to 195 and the thermostat opened and head temp receded to approx 170 degrees.
Where is the temp sensor on a GM Truck?
Replace the “temp switch”. It’s on the right side of the block, in between the exhaust headers, it’ll have a single green wire going to it from past the alternator. They cost like $20, and it’s an easy replacement. Be sure to get the “temp SWITCH” and NOT the “temp SENSOR”.

What to do if your engine temperature Guage is not working?
That wire that’s on the temp sensor between the #1 & #3 spark plugs… Pull that wire off, leave it unhooked & turn on the key. The guage should stay to the left. Now with the key still on, momentairly ground that wire to the engine. Your guage should peg out. If it does both of these correctly, then you need a new temp sensor.
Why is my GM temp sensor not working?
Temp sensors have a “calibrated resistance scale” to the system they are providing temp data to. Wrong connectors is a big red flag!!! I’m leaving you the GM resistance scale for you temp sensor. If your temp sensor resistance values are not the same as the chart when fully warm.replace the sensor.
What should I do if my Guage sensor is not working?
Your guage should peg out. If it does both of these correctly, then you need a new temp sensor. If it does anything else with either of these two tests, then it’s a dash cluster/guage problem. Check your thermostat first! If your thermostat is bad, the engine will never warm up, and that can make it look like the gage is bad.
Where is the temperature sending unit on a GMC Truck?
Replacement temperature sending units for 1967-69 Chevrolet/GMC truck models with factory warning lights. The temperature sending unit screws into the side of the cylinder block or on the intake manifold and allows the temperature gauge to function properly. If your temperature gauge is not functioning properly, replacing the…
How to check a temperature gauge and sending unit?
Here I check to see if the stock Chevy temperature gauge works by using a potentiometer to see a specific ohms resistance. The potentiometer can be set to mimic the temperature sending unit. This way you can start to isolate the problem why the temperature gauge does not work correctly.
Where is the temperature sensor on a Chevy truck?
The sensor is located under the hood, mounted to the front driver side… The temperature sending unit screws into the side of the cylinder block or on the intake manifold and allows the temperature gauge to function properly. If your temperature gauge is not functioning properly, replacing the…
Where is the water temperature sending unit located?
The temperature sending unit screws into the side of the cylinder block or on the intake manifold and allows the temperature gauge to function properly. If your temperature gauge is not functioning properly, replacing the… Water temperature sender for use with Dakota Digital electric fan controller (DD2700).
What’s the temp on my GM Silverado truck?
The exact thing happened with my truck 2006. Battery dead, changed it, and now temp gauge sets on 160. I will try and do as you did. Thanks for the help. Just changed battery on my 07 Silverado and the temp gauge will come up and then drop back to very low and stay there.
Why is my oil pressure reading low on my GMC?
In this video we show common causes and solutions for GM vehicle experiencing low or no oil pressure reading on the instrument panel. This condition may also include a low oil pressure warning on the drivers information display and an illuminated check engine light and/or stored codes P0521 P0523 Watch this video for more information.

Why are all the gauges on my GM Truck not working?
Last night I was comin home from the store and realized my speedometer wasn’t working (ins’t the first time) so i hit the dash, then realized NONE of the gauges were working.. Gas gauge, almost empty. Water temp, cold. No oil pressure. The alt wasn’t charging. No tac and no speedometer.
What does it mean when your temperature gauge is not working?
The temperature sensor/sending unit is faulty. If this is the case your sensor will be reading the coolant temperature incorrectly and sending the wrong signal to the gauge. This could work in either direction and read as cool when it’s running hot or hot when it’s running cool. A malfunctioning circuit in the temperature gauge
What should I do if my gas gauge stops working?
