How do I drain coolant from the coolant system? The car is overheating and the heater does not work only the fan works. I need to know how to drain the coolant out of the car so I can add new coolant.

Hello, I'm Danny.

Here is the information you requested. I don't think this issue is being caused by bad coolant rather a thermostat issue. It's possible the thermostat is faulty-or stuck closed therefore not allowing the coolant to circulate through the engine and heater. Here are two tutorials showing how to replace an thermostat and change, flush the coolant:

I've attached picture steps below on how to change the thermostat on your car. I've also included a picture below of the type of coolant to use and your cars capacity requirement. Hope this helps and thanks for using 2CarPros.
