Yes. Your car may experience increased fuel consumption once your thermostat is removed. By cooling the engine far below the normal temperature, the coolant releases more fuel than is needed for combustion.

Can a thermostat affect gas mileage?
Temperature Reading is Erratic: In some instances, the thermostat doesn’t get stuck in just one position. This will prohibit the coolant from flowing properly. This will lead to reduced engine performance as well as poor gas mileage and engine damage.
Does removing thermostat increase fuel consumption?
High fuel consumption
Your car may experience increased fuel consumption once your thermostat is gone! The coolant is released to cool the engine far below the normal temperature and thus make the CTS release more fuel than the standard quantity required for combustion.
Does a car run better without a thermostat?
If there is no increase in temperature, the engine will clog and stop entirely. This is dependent on how old the car is, but when you drive without a thermostat, the car will consume more fuel. This is because the engine control module (ECM) assumed the engine is yet in a cold state and needs powering up.
What causes fuel consumption to increase?
This bad habit is threefold – driving too fast, accelerating too quickly, and stopping too suddenly. All three of these actions lead to high fuel consumption. Where possible, you should accelerate slowly and drive with the speed of traffic.
How do you know if your car thermostat is working?
Start your car’s engine and allow it to idle. Look through the radiator filler neck to see if the coolant flows. At this time, it should not be flowing as your car has not reached the operating temperature to cause the thermostat to open. If you find the coolant is flowing, it means the thermostat valve is open.
Can coolant affect fuel consumption?
Improved fuel economy
“The coolant itself doesn’t save fuel, but it allows fuel saving strategies that you can’t do with a water-based coolant,” says Mike Tourville, Director of Marketing, Evans Cooling Systems.
What will happen if thermostat is removed?
TOM: But taking out the thermostat can actually do quite a bit of damage on a modern car. Most cars now have computers, which constantly monitor the engine temperature and adjust things accordingly. If the computer thinks the engine is cold–and it WILL be cold without a thermostat–it’ll richen the fuel mixture.
Why you should not remove your thermostat?
Removing the thermostat will simply make the engine to over cool. That is bad. It will increase fuel consumption, as the engine CTS (coolant temperature sensor) will assume the engine’s not up to normal operating temperature, and simply inject more fuel in.
How do I know if my thermostat is bad?
7 Ways to Tell Your Thermostat Is Broken
- Thermostat Has No Power.
- AC or Furnace Won’t Turn On.
- Heater or AC Won’t Turn Off.
- Thermostat Doesn’t Match Room Temperature.
- Thermostat Doesn’t Respond.
- Short Cycling.
- Thermostat Forgets Programmed Settings.
- Thermostat Replacement Services.
How do you tell if a thermostat is bad in a car?
Here are the signs your car thermostat is failing: The temperature gauge reads high and the engine overheats. The temperature changes erratically. The vehicle’s coolant leaks around the thermostat or under the vehicle.
How do you test a thermostat?
Standard thermostats: Enlist a friend or family member to assist, Position one person by the thermostat and one person by the furnace. Slowly turn the thermostat from off to heat and increase the temperature. Both the thermostat and furnace should make a sound.
How do I fix high fuel consumption?
10 ways to reduce fuel consumption
- Keep tires pumped up. Tires that are underinflated have a higher rolling resistance on the road.
- Lose the weight in your boot.
- Drive with AC.
- Don’t go too fast or too slow.
- Remain steady when accelerating.
- Avoid braking aggressively.
- Cruise in top gear.
- Practice predictive driving.
What causes poor fuel efficiency?
Clogged or Damaged Fuel Injectors
One of the most common culprits for a drop in fuel efficiency is dirty fuel injectors. Fuel injectors are the nozzles that spray fuel into each engine cylinder. A fuel injector’s spray pattern must be very precise to properly mix with air and combust inside the engine.
What affects fuel consumption?
Driving behaviour: Rapid acceleration, speeding, driving at inconsistent speeds and even extended idling can increase your fuel consumption. The smoother you drive, the better your results will be. Drive smarter – and reduce your fuel consumption by up to 25%!
What can a faulty thermostat cause?
If the thermostat becomes stuck in the open position, there is continuous flow of coolant into the radiator causing the engine to run cold. Overcooled engines run inefficiently, which leads to increased fuel consumption and higher emission levels and engine parts enduring more wear.
Does changing coolant improve performance?
A mechanic will then finish the coolant flush by adding fresh antifreeze to your engine along with a conditioner that will keep it protected for longer. This process improves the health and protection of your vehicle, so you will likely notice an immediate boost in engine cooling and performance following this service.
Does water pump affect fuel consumption?
It can. If the pump is failing and not providing proper fuel pressure to the system, it can cause a reduction in mileage by simply not providing enough fuel for the engine to run smoothly, which would cause a reduction in mileage.
What happens if engine runs too 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.
How important is a thermostat in a car?
The thermostat of an engine is a simple mechanism, but very practical as well as useful and necessary. This part of the vehicle fulfills the function of regulating the temperature of the engine and, through its radiator, controls the overheating of the engine, that is, it is used to cool and warm the car engine.
What does a car engine thermostat do?
The thermostat is like a valve that opens and closes as a function of its temperature. The thermostat isolates the engine from the radiator until it has reached a certain minimum temperature. Without a thermostat, the engine would always lose heat to the radiator and take longer to warm up.
