Why does my car temperature go up when I stop?

Reasons a Car’s Temperature Gauge Spikes at Stops One the reason a car heats up when stopped, but cools when driving, is that air is moving over the engine and causing the fan to spin. Not necessary the end of the engine, but enough to cause some level of damage. Busted fan belt. A fan belt can loosen or just snap.

Is it normal for your car temperature to fluctuate?

If you’re driving your car and the temperature gauge is stuck on high, low, or going crazy, the issue is most likely with your thermostat. The job of the thermostat is to regulate the movement of coolant in your vehicle and maintain the best temperature for engine operation.

Why does my car overheat when sitting in traffic?

If the coolant level is low, that tells you there is a leak somewhere in the system. If there isn’t enough coolant in the system, the engine can easily start to overheat while you sit at a stoplight or in traffic. You can check the coolant level yourself by popping the hood and taking a look under the radiator cap.

Should I run my car while adding coolant?

Yes, run the engine After you do any work involved with draining the coolant you will either have an exact process to remove air from the cooling system or you will simply run the engine. If you don’t the gasses (air) will expand at a greater rate than liquid when the engine get’s hot.

What is the ideal engine temperature?

between 195 degrees and 220 degrees

How hot is too hot for engine coolant?

Too Hot. The acceptable range for an engine to run at sits between 195 degrees and 220 degrees Fahrenheit. This assumes a person is running a 50/50 mix of antifreeze and water.
