What will removing a thermostat do?
That’s because the thermostat creates a small restriction in the cooling system which allows the coolant to take on more heat. When you remove the thermostat, you remove that restriction and the coolant flows faster, taking on less heat and actually increasing the engine temperature.
Can I replace my Honeywell thermostat with a smart thermostat?
The devices most commonly called “smart thermostats”, such as thermostats from Nest, Ecobee, Honeywell, etc., are only compatible with “low voltage” 24v HVAC systems.

What happens when thermostat is stuck open?
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.
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 do I know which Honeywell thermostat I have?
The fastest way to see your thermostat model number is to look for it on your thermostat ID card. If you do not have a product ID card, the fastest way to find the model number is by removing the thermostat from the wall-plate.
