Does drilling a hole in thermostat affect engine temperature during cruising speed? (Please read my explanations before answering)

Should you drill a hole in car thermostat?

The main reason to drill a hole in your thermostat is to keep your car cooler by controlling the KR. However, these holes only reduce the overall engine temperature by about 5 degrees.

What are the possible effects of missing thermostat in the engine?

If the temperature doesn’t increase, the engine will choke and stop ultimately. In fact, the heater will produce the cold air as well. Secondly, there is a chance that the water will flow through the radiator so fast that it will not stay in the radiator long enough to cool down, which will make your engine overheat.

Does the thermostat control engine temperature?

You may be surprised to know that most cars are equipped with a thermostat as part of the engine’s cooling system. While your home’s thermostat is used to monitor the interior of your home, your car’s thermostat is used to regulate the temperature of the engine to help the engine stay cool.

What happens if you remove the thermostat from your car?

In a car without a thermostat, your engine will never reach its optimal operating temperature and your heater can blow away some cold air either. A malfunctioning thermostat causes your engine to think it is warm outside, causing it to adjust the gas mixing valve and fuel to get more fuel out.

What happens if you drill a hole in a thermostat?

It makes it easier to burp the air out of the cooling system – the little hole keeps air from getting trapped under the thermostat.

What does drilling a hole in thermostat do?

The hole serves two purposes. One is to let trapped air out of the engine and the other is to allow some water flow to let warm/hot water get to the thermostat motor before the engine overheats trying to open the thermostat.

Will an engine overheat without a thermostat?

Running an engine without the thermostat can cause the engine to overheat due to the coolant passes through the engine too fast and will not let the coolant absorb the heat from the engine.

Will a car heater work without a thermostat?

The warmth of the engine is what makes heat inside your car when you turn on the heater. So, if you drive without a thermostat, your engine will never reach its optimal operating temperature and your heater may blow cold air.

Why is my car overheating with a new thermostat?

If your car is overheating with a new thermostat, you could be dealing with a clog in your radiator and/or heater core, a bad water pump, a broken radiator, or any number of other coolant-related issues. The first and most important thing is not to drive your car until the issue is resolved.

Can I drive without a thermostat?

You can drive without a thermostat for short periods of time. Without the thermostat in place, your engine won’t work at the required temperature range. This action causes the engine to malfunction and affects the overall performance of your car. This can also cause your engine to take a longer time to warm up.

Does thermostat cause overheating?

Faulty Thermostat

Once the engine reaches operating temperature, the valve will open and coolant will begin to flow through the engine. A faulty thermostat might remain closed even when the engine is hot, which can quickly lead to overheating.

What causes a thermostat to fail?

Sometimes the thermostat fails and must be replaced; there are four main reasons for failure: overheating, sludge, defect and age.

How do you know if your thermostat is stuck closed?

Checking For the Signs of a Bad Thermostat

Look to see if the coolant is swirling/flowing immediately — that means the thermostat’s stuck open. If the coolant doesn’t flow after 10 minutes or so and continues to be stagnant after the temperature gauge indicates it’s hot, the thermostat’s likely stuck closed.

What happens when thermostat is stuck closed?

Your vehicle’s thermostat opens to allow coolant to flow through the radiator and cool the engine down. However, if the thermostat gets stuck in the closed position, the coolant can’t flow through the radiator and can make your engine overheat.

How do you know if a thermostat is not working?

The most common signs of a broken thermostat are: The thermostat display is off or is non-responsive when you try to adjust it. The display on the digital screen is faded or incomplete. The furnace or air conditioner does not respond when you adjust your thermostat.

How do I test my thermostat?
So if you're in the furnace you just want to make sure that you have this door switch shut in order to make sure that you have power to the thermostat.
