Thermostat Replacement, Car Overheating
Thermostat replacement is generally done if a car is overheating. The other possibility is that the car is no longer heating up correctly due to the thermostat sticking. Before changing the thermostat verify that the engine coolant is full and that the cooling fan is working when the car is up to temperature. You will also need to find out the recommended temperature of your car’s thermostat when you purchase it. This sunbird has a 3.1 liter v6 engine that will randomly overheat. Another possibility is that the water pump is bad. Removing the radiator cap (if possible) when it is cool, can some times be helpful to see if flow is occurring although it won’t always work.
