On most vehicles, the temperature gauge reads cold until the engine has run for a few minutes. ... With the thermostat stuck open, the engine can be overcooled, causing a low temperature reading. If this is the case, the thermostat may need to be replaced.

Can engine temp be too low?
Having the engine operate below normal operating temperature causes significant wear and tear, notably on the cylinder liners and piston rings. Nothing you can do about it, just get the thermostat replaced asap.
Can you drive a car with low temperature?
It's not recommended to start driving the car immediately after starting it because the temperature of engine oil will be low. ... Because by doing so engine will take more time to get heated since rpm is low.
Is it bad if your car runs cold?
If you run your engine cold all the time, you'll most likely experience increased fuel consumption across the board. Additionally, you'll find higher amounts of carbon buildup at various parts of the engine. The most damaging effect of feeding a fuel-rich mixture to the engine is excess fuel reaching the exhaust.
What happens if my coolant temp is low?
Symptoms of coolant temperatures being too low will first be the check engine light. Another symptom is increased fuel consumption. ... If the coolant is not in the desired range, then the control strategy will change in order to heat the engine up faster while still ensuring normal engine performance.
Why is my engine temp dropping?
The reason the temperature gauge drops when driving is because there's much greater airflow through the radiator when you're at speed than at idle. That increased airflow drops the temperature on the coolant coming into the engine.
What causes low engine temperature?
The most common reasons for the temperature to remain low include: A thermostat stuck open. A bad engine coolant temperature sensor. A locked fan clutch.
What temperature is too cold for cars?
If your car gets extremely cold, the battery could freeze. Now, the good news is that it must get extremely cold before that happens. Some experts suggest as cold as negative 76 degrees. That said, even at 32 degrees, your battery can start having problems.
What happens if you don't warm up your car?
It lets the richer gasoline mixture strip the oil from the engine's cylinder walls, increasing engine wear. A rich mixture from a cold engine can damage your catalytic converter. Your vehicle pollutes a lot more when idling in cold weather. Long periods of idling are illegal in most places and could get you fined.
What happens if you don't warm up your car before driving?
The more you drive with your engine cold the faster the cylinder and piston will wear out. Simply leaving the engine to idle doesn't warm it up efficiently, so the car's application will remain cold until you start driving. ... This happens when fuel passes through the pistons and mixes in with the oil.
What happens if my engine is too cold?
When your car engine is cold, the fuel injectors send more fuel through the system. As the engine warms, it needs less fuel to run efficiently. So the longer you let a cold engine idle, the more fuel you waste and the more you increase the chance of fuel residue build up.
Does a cooler engine run better?
Performance vehicles move parts even quicker, from engine internals, to transmission gears, to differentials, only making components hotter. Cooling temperatures throughout the drivetrain will not only keep a car running longer, but will potentially help it run quicker.
How do I know if my thermostat is stuck open?
Symptoms of a bad thermostat
Thermostat stuck open: When the thermostat is stuck open, the engine temperature drops below normal when driving, especially on the highway in cold weather. A stuck-open thermostat can also cause lack of heat from the heating system. The Check Engine light may come on too.
