Why does the temperature gauge fall at idle?
Why does the temperature gauge fall at idle?
The difference might be that at highway speeds, the air blows hotter, but doesn’t at idle. This would mean air pocket in the coolant. if the air blows the same in both schemes, but the gauge still falls, remove the thermostat, ad drill a small hole thru it, max 1/8″.
Is it normal for car temp to fluctuate?
Thanking you in advance. Yes this is normal. When the A/C is ‘on’, both fans will come ‘on’. At least you know the fans will run. Get to work bleeding the air out of this cooling system and I think that will cure the temp fluctuation problem. IIRC, Honda has bleed screws on the high spots of the engine to help you.
Why does my car get hotter at idle?
Now, do the same thing from cold start in city driving, or just at idle in the driveway. The difference might be that at highway speeds, the air blows hotter, but doesn’t at idle. This would mean air pocket in the coolant.
When does it get hot on the highway?
Thank you for your time around town it’s fine in 110 plus degree weather only on the highway around 70 ish mph for more than 15 miles is when it starts getting hot however when stuck in stop and go traffic it runs perfectly cool so I’m stumped. This says your dealing with a circulation issue.

Why does my engine RPM fluctuate at idle?
Below are a few explanations as to what might be the issue and cause for that fluctuation. In older cars, your spark plugs might just need replacing. A quick tune-up can greatly help the engine performance of your car and how it operates when it’s at idle.

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 does intermittent mean on car temperature gauge?
The code indicates that a wire from the engine coolant temperature sensor, is shorting to ground, or open, somewhere. Of course, “intermittent” means: sometimes. The engine computer, in response, turns on the engine cooling fans, to lower the reported hot engine coolant temperature.
What do you mean by temperature gauge is fluctuating?
Temperature gauge is fluctuating, sometimes showing overh… Q: Temperature gauge is fluctuating, sometimes showing overheating.
Why does my a / C blow cold at idle?
If your evap core next to the heater core is freezing your not getting enough air flow through. And also your heater core helps to keep it from freezing over. It’s hard to determine how much freon is going in using the old style manifold gauges. The best way is to use a Robinair A/C machine.
What causes a car’s temperature gauge to dip and rise?
If you are referring to the dip and rise as indicated by the temp. gauge, this is completely normal. There is a thermostat in the head which controls the coolant movement. When the water/coolant heats to a set temperature, such as 75 degrees C, a wax pellet expands the valve in the thermostat, and cooler water is passed into the head.
What should I do if my temperature gauge goes down?
Is there a way to check if the engine fan stays on when the temperature gauge goes down, since this only happens when i am driving and it stay down only for a few seconds. It sounds like a simple sticky thermostat. Try replacing that for about $15+/- for starters. Post back with the results. I already had the thermostat replaced a few weeks back.
