Yes, I can help you, I have this car lol. First, start with the engine cold, then loosen the coolant reservoir cap. Then start the engine and allow it it get warm but not hot. Shut the engine off and disconnect the lower radiator hose a the radiator into a drain pan/container. Once it is done reattach the hose and refill with coolant, (there is no drain plug on the system FYI). Start the engine until fully heated and reinstall the radiator cap. Be careful of the old coolant is is poisonous, I would take it to the auto parts store for proper disposal. Please go over this guide as well.
