What happens when the temp gauge is on Hot?
When the temp gauge is on hot and I rev the engine, temp gauge needle goes down a little bit. Fan switches on on Hot reading, then turns off when the needle goes down a bit, still the engine is not smoking nor does it feel really hot. It’s just a normal temperature as far as I can tell.
What makes the temp gauge jump on a Honda?
Both of these will lead to excessive coolant overflow due to lack of circulation causing hot spots to develop where the coolant is boiling and expanding to push coolant out of the system. This also creates air pockets which can make the temp gauge quickly jump or fall.
What’s the temp gauge on a Pontiac Vibe?
2005 Pontiac Vibe wagon…over 300,000 no issues until recently. The temp gauge goes to overheat. Here is what has been done in the past two weeks. New thermostat, proper coolant, new radiator cap, sensor, and just installed a used gauge panel. Fan is plugged in….heat sensor gun shows normal temps.
What to do if your temperature gauge is pinned Hot?
If you measure around this value (or definitely not near 140 Ohms) with a cold engine then the unit is faulty and needs to be replaced. A quick test is to disconnect the lead from the sending unit, turn on the ignition and observe the temp. gauge. If it registers ‘zero’ then most probably the sending unit is faulty.
Is it normal for the temp.gauge to go red hot?
Yes, coolant level is fine! The temp. gauge goes to red hot or pinned as soon as I start the car cold. And…after approx. 15 min. driving locally, the engine doesn’t seem to be overheated. so I’m assuming that the thermostat is working fine. I’m just afraid to drive it longer or farther when the temp. gauge says red hot.
What should the temperature gauge be on a hot engine?
With a hot engine it should measure 30-50 Ohms. If you measure around this value (or definitely not near 140 Ohms) with a cold engine then the unit is faulty and needs to be replaced. A quick test is to disconnect the lead from the sending unit, turn on the ignition and observe the temp. gauge.
Which is the best high temp wire terminal?
Professional online source for high temperature wire terminals and crimp connectors for electrical wire. Our hi temp crimp terminals are one piece, nickel-plated steel construction for reliable circuitry up to 900°F (900 degrees Fahrenheit) Made in the USA.
What causes a needle gauge to read incorrectly?
You mentioned the electrical system which actually can cause needle gauges to read incorrectly. If you can thump the gauge with your finger and cause the needle to jump to and remain at a different reading then suspect a loose or dirty connection at the back of the gauge.
Why is my coolant temp gauge not working?
The coolant temp gauge gets its input from the BCM and the AC gets told to do its thing there as well. You could have anything from a dirty connector (“fretting”) to a failed BCM.
Why does the temperature needle go up on my car?
If your temperature needle goes up and reaches the red zone, it could be an indication that your engine is overheating. Another possible reason is that you might be running out of coolant due to a leak or evaporation.
Why does the temperature gauge on my car go up?

Where is the temperature gauge on a BMW?
The engine temperature gauge is located in your BMW’s instrument panel; it provides information about the engine’s current operating temperature. It is marked by a thermometer symbol, and uses a needle to illustrate the vehicle’s engine-temperature level.
