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. To fix either of these issues, we'd advise that you engage a proven auto mechanic.

Why does my temperature gauge go up when I stop?
If your car begins to overheat when idling, but the temperature gauge moves back down once you get going, it's most likely due to a broken radiator fan. ... However, when your car is sitting still, the radiator fan should kick in, keeping the air moving over the radiator to help cool down the coolant.
Why does my temperature gauge go up when idling?
Car Temperature Gauge Goes Up When Idling. You may notice that the temperature on your vehicle only rises when you're idling, and here's why. When your car is moving, the air is passing across the fins of the radiator. When that happens, the heat is taken away from the liquid coolant on the inside of the radiator.
Why would car temperature needle goes high?
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.
Why is my car overheating when the coolant is full?
The primary cause of engine overheating is a lack of coolant. But, if your car is overheating with full coolant, it may be something more severe. Other possibilities include a faulty water pump, a radiator blockage, a stuck thermostat, or even a blown head gasket.
Why is my car running hot but not overheating?
If you find that you've got a car running hot but not overheating there might be a few reasons: Clogged or damaged radiator. Low coolant level. Damaged water pump or thermostat.
Why is my car overheating with a new thermostat?
You could be having a problem with your radiator being clogged up. This will cause the flow of the coolant in the system to be restricted, causing the truck to overheat. A clog in the heater core could also cause this problem. ... The most likely cause is a clogged radiator.
What makes an engine run hot?
Why Do Engines Overheat? Engines can overheat for many reasons. In general, it's because something's wrong within the cooling system and heat isn't able to escape the engine compartment. The source of the issue could include a cooling system leak, faulty radiator fan, broken water pump, or clogged coolant hose.
Why is my temperature gauge reading hot but not overheating?
This problem can be due to a low coolant level in the radiator, a faulty thermostat, a bad radiator, a damaged head gasket, a faulty water pump, or it might just be a bad temperature sensor or gauge giving a false reading.
What causes a car's temperature gauge to fluctuate?
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.
What can a bad thermostat do to a car?
Overheating. Because your thermostat controls temperature of fluids from the radiator hose, a bad thermostat will cause your car to overheat. When the engine temperature has reached the operating level, it should allow coolant to flow to the engine and regulate the heat.
