A stuck car thermostat can cause all sorts of engine problems, from overheating to poor fuel economy. Learning how to diagnose and fix this issue can save you time and money. This guide will walk you through everything you need to know about how to fix a stuck thermostat in your car.
Understanding the Car Thermostat
Your car’s thermostat is a small but vital component. It regulates the flow of coolant through your engine to maintain optimal operating temperature. A thermostat stuck open will cause the engine to run too cool, while a thermostat stuck closed will lead to overheating. Both scenarios can cause significant damage if not addressed promptly.
