Would thermostat be stuck if runs hot in jeep?

A stuck thermostat can definitely cause a vehicle to overheat. When a thermostat is stuck open, it allows coolant to flow through the radiator at all times, resulting in a lower engine temperature. This can cause the engine to run cooler than it should, which can lead to poor performance and fuel economy.

On the other hand, a thermostat that is stuck closed prevents coolant from flowing through the radiator, causing the engine to overheat. This can lead to engine damage if the problem is not addressed promptly.

If you suspect that your Jeep's thermostat is stuck, it is important to have it checked by a qualified mechanic as soon as possible.
