Why is my temperature gauge fluctuating up and down?

Why is my temperature gauge fluctuating up and down?

One common cause is a defective thermostat, a component that is inexpensive and easy to replace. Other causes of a fluctuating temperature gauge are a failing radiator fan, insufficient coolant level and a leaking cylinder head gasket. A failing radiator fan will be erratic.

Why does my thermostat in my car keeps going up and down?

The main reason why car temperature gauge goes up and down while driving is because something is not working properly in your car’s cooling system. It could be the radiator fan, water pump, thermostat valve, coolant, or the gauge itself.

What does it mean when your car thermostat goes up and down?

The primary reason your car temperature gauge goes up and down while driving is simply because a component in your cooling system is not functioning correctly. This could be the thermostat valve, radiator hoses, radiator fan, the temperature gauge, or the coolant itself that circulates around cools off the engine.

What does a fluctuating fever mean?

Remitting – the most common type with daily temperatures fluctuating above the normal range. Intermittent – daily temperature drops into the normal range and then rises back above normal. If temperature fluctuates widely causing chills and sweating, it is called a hectic fever.

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.

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 happens when the temperature of an engine increases?

This is to help the engine warm up to running temperature. As the temperature of the engine and hence thermostat increases, the thermostat opens (usually about 90 degrees or so) and lets coolant flow throughout the engine and through the radiator, this cools the engine. You can see the cycle will continue,…
