What happens when your engine temp drops to cold?
If your thermostat failed, it wouldn’t turn cold while driving. It would never get hot. THe thermostat is supposed to open as the water temp goes up. If it is stuck open, the water would never heat up. When your indicator is cold, are you getting heat from your vents??
What causes the temperature gauge to go down while you are driving?
The core, and thus the heating system, gets its thermal energy from the engine’s cooling system. Thermostat valves can fail in one of three ways: open, closed or stuck halfway. If the valve sticks in the closed position, coolant will constantly recycle through the engine without going to the radiator, causing the engine to overheat.
Why is the coolant on my car so cold?
When I stop and let the engine idle, it returns to the normal range. Could be that your thermostat is stuck in the open position which doesn’t allow the coolant to heat up when you drive. Is your coolant actually getting cold, or is it just your temperature reading?
Why is my car so hot when I idle?
When this happens you will notice a temperature spike and drop occasionally as the fan comes on and off. When your thermostat is not working properly or is stuck closed, this will not allow the coolant to properly circulate through the engine, which may cause the engine temperature to fluctuate erratically or in some cases just remain hot.
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

Why does my car’s temp keep going up?
Happening more lately wheezing traffic causing engine to sound likes it’s working harder to accelerate and temp fluculates My car has 100500 miles. My car has an automatic transmission. Overheating can be caused by a number of things such as low coolant levels, a faulty thermostat, a clogged radiator or a failing coolant fan switch.
What to do when your coolant temp goes up?
Turn the heater on at high speed. Rev the engine and hold for a few seconds. You don’t need mega high RPMs. Just enough to get good flow through the system. Check flow at the radiator. Temperature swings are common in colder climates. Thermostats are notorious for swings.
