If you don't have a thermostat will that make you car overheat

Report as

No, a thermostat is what opens up when your car gets warm and needs to cool down, if you do not have a thermostat it will be running coolant thru all the time, so your car will run cool.

A thermostat is Typically only around $5. If you don't have one, you won't have heat in your car and it will run very rough.

A broken thermostat will.

Actually, it's more likely that your car will run too cool if you remove the thermostat completely.

The thermostat RESTRICTS water flow until it reaches a predetermined temperature. When it reaches that temperature the 'stat opens, allowing the water to flow to the radiator where it is re-cooled.

So... If there is no thermostat, water flows through the radiator unrestricted which could cause the engine to run too cool, reducing oil flow and lubrication, possibly causing serious engine damage.

If you don't have a thermostat, your car will NOT overheat.

People run without thermostats in hot climates to keep the car cooler. However if you are in a northern climate and want heat in your car, running without a thermostat will NOT allow your engine to heat up to optimal temperature, and therefore you won't get any heat through your heater core.

So since you did not say where you are located, I can't be more specific.
